Development Direction of Solar Street Lamp Manufacturers
Development Direction of Solar Street Lamp Manufacturers
There are many solar street lamp manufacturers. In the face of fierce competition in the industry, solar street lamp manufacturers have to face some problems if they want to develop. If they want customers to find you or patronize you again, the premise is that you are a good manufacturer in all aspects, What kind of development direction should solar street lamp manufacturers have now?If the solar street lamp price has an impact on customers, it can only be that the solar street lamp manufacturer has not really succeeded. Because the price war is never an inevitable factor for the development of manufacturers. Today, you can give customers a very low price and reduce the street lamp price by reducing the Watts actually needed by customers. It may not be guaranteed that another manufacturer will use the same method to reduce the price and attract customers. You are lowering the price, and your opponent is also lowering the price. In this way, long-term development will only hurt both sides.Therefore, the price war is not the correct development direction of solar street lamp manufacturers. The correct direction should be to focus on product production, improve product quality and cost performance, and do a good job in after-sales service at the same time. It's like a 99 yuan smartphone and a Samsung phone with hundreds or even 3000 yuan. There is a big difference in price, but we still choose Samsung phone because of its high brand, good performance and cost performance in all aspects. Therefore, the development direction of solar street lamp manufacturers should not tangle in price, but do a good job in their products and improve their brand.

Girl Power! India's 'solar Gal Pals' Light Up Rural Homes
Girl Power! India's 'solar Gal Pals' Light Up Rural Homes
ALWAR, India (Thomson Reuters Foundation) - Buffalo trampled over it? Rain drenched it? Child dropped it? No problem. This solar flashlight can endure it all, said Bassi in a pitch to her neighbours in rural India to convince them to power their homes with clean energy instead of polluting fuels.Bassi is one of 2,500 "Solar Sahelis", or solar women friends, who fan out to different villages and persuade families to use solar energy in the western desert state of Rajasthan, which sees about 300 days of sunshine every year.With unreliable electricity and hours-long power cuts every day, many rural families in Rajasthan are often forced to rely on candles, kerosene oil lanterns or burning wood, which emit soot and noxious fumes.They not only can lead to premature death due to disease, but can also cause fire accidents and burn injuries.That is why solar is the way to go, 26-year-old Bassi, who goes by one name, told the Thomson Reuters Foundation in her village of Moonpur, about 130 km (80 miles) from state capital Jaipur, where buffalos and cows wander the dusty streets."They just makes more sense - affordable, long-lasting, durable and safe," said Bassi, who has sold up to 32 solar flashlights since becoming a Solar Saheli last year.Even then, Bassi said it can be a challenge to win over villagers who are usually wary of the initial higher costs and distrust solar products due to experience with some flimsy products from China.The most popular product, the "Solar Rakshak", or solar protector, flashlight costs between $10 and $20, while a regular battery-run one would be about $5.But once doubts are cleared, almost every customer is satisfied, said Bassi.Kamlesh Devi, a mother of two, bought the Solar Rakshak in June after Bassi assured her that it would save her frequent trips to the market for new batteries and lights, and help her children study without any irritation to their eyes."I used to buy flashlights for 300-400 rupees (about $5) that would malfunction within six months. Sometimes it would fall here or there. The batteries would die quickly. But this is a great thing," said Devi, her head veiled with her sari."The kids are studying well. Until 10, 11 at night, even if there is no electricity, they study very comfortably," she said.Jaipur-based Frontier Markets, the social enterprise behind the project, said its mission is to provide over 10 million clean energy products to 30 million households in India by 2020.But the project is not just about going green.It also aims to empower women in the male-dominated, conservative state, where child marriage is rife and girls are routinely denied an education and live a life largely confined to home.Bassi's life was headed there too. Forced to marry at 17, she was regularly beaten up by her husband before she ran away and moved back in with her parents.When she insisted on studying further, her elders refused, saying she brought shame to the family.That is when Frontier Markets found Bassi in a self-help group for women and trained her to spread awareness and sell solar lights in remote areas of Rajasthan."If not for this. I would have just stayed at home, tended the buffalos and done household work. That is all I would have been good for," said Bassi.Having never ventured out much or spoken in public before, Bassi said she was jittery at first, unsure whether she would be taken seriously or be able to sell anything."But now I feel like I have no fear," said Bassi, who unlike most rural women travels miles out of her village, interacts with men and earns an income - up to 2,000 rupees ($28) every month."Women are not weaker than men. At least I do not have to depend on anybody for money," she said."On days when I feel like buying something or wearing something new, then I know I have my own money and I can do whatever I want."The Solar Sahelis have collectively earned more than $2.5 million by lighting over 500,000 homes, according to Frontier Markets."In order to drive true women empowerment, they need to be economically secure. The second you put money into women's hands, everything changes," said Ajaita Shah, the 34-year-old founder of Frontier Markets.The rise in family incomes has made the Sahelis confident and more involved in household decisions, she said."The fire we saw in some of these women, it is like they were finally recognising that their voice has value," said Shah.Repeated studies show that when women control the family's finances, they invest more in their children's education, healthcare, businesses and communities, which can be a step out of poverty.While such programmes seek to boost women's rights, experts warn they can backfire at times as they upset traditional norms and spark conflict, especially in conservative pockets of India.Rajasthan is known as much for its beautiful palaces, camel-back desert safaris and colourful apparel as for its age-old customs like purdah, or veiling, of women.It is home to some of India's poorest villages where politically powerful councils, mostly comprising elderly men, have an iron grip over social and moral life.Women are often expected to conform to established gender roles such as being the main caregivers who look after the home and children despite modern, urbanising times, experts say.That is why it is essential to sensitise villagers about changing dynamics, said Shashank Bibhu of CARE India, a charity that works for women from poor, marginalised communities."Otherwise, in the past, we have seen that it has led to domestic violence," he said.He urged organisations to counsel communities about gender equality and promote supportive men as role models who share household responsibilities.For Radha Devi, working as a Solar Saheli has not been very easy due to the lack of help from the men in her family."I struggle to balance household work and this work," said the 37-year-old, who became a Saheli last year."Men do not have to worry about household work . so they progress in life. But women have to think a lot about how they will take out time for their jobs," she said.Still, that does not dim her hopes of making it big one day."The plan is to open up my own store . and make a name for myself," she said, wearing a bright yellow Solar Sahelis vest."Success takes time. One should not lose confidence."Buy Best Solar Light Products Online in India at Best PricesWhere to Buy Best Solar Light Products in India?

When I heard there are people who "waste" their money on things such as pool lightings, I wondered how someone can be so stupid to spend money on such useless things. I mean, those shiny and colorful lights are cool and all, and they do not cost so much money. Still, I did not see any purpose of those lights, except they make your pool nice and bright. I generally do not buy things unless I realize how they can really be useful to me, so I thought I would never buy anything like best above ground pool light. When readers of this site buy through our link, we may earn an affiliate commission. Therefore this affiliate commission never biased our product recommendation. Our motto is to promote the best products for consumers, through detail research and market analysis. I would rather spend the same amount of money on something else, or even donate it to charities. However, my family convinced me that we should buy these lights. However, I was not so willing to buy them, but in the end, my family prevailed. So, I bought one of the above ground pool lights underwater. After several days, I was heavy hearted at admitting my family was right about it because I noticed many benefits from pool lighting. Without further ado, let's see how above ground pool light improved my pool experience. Swimming at night is just fun! When I bought pool lights, I could indulge in swimming in my above ground pool for the first time in my life. I've never thought that swimming at night can be that interesting and fun. I highly recommend it to anyone who has never tried it before. If you have never tried it before, you do not know what you are missing. Also, if you have young kids, they will be especially happy because you bought a pool light. I remember when I was a kid, I hated seeing Sun falling down because I knew it means the end of enjoyment in the pool. I beg my parents to let me stay longer in the pool, but they said it's unsafe, not smart and they did not understand why I would have like to stay in the pool at night. Of course, I did not understand them as well. So, if you buy pool light, your children will be very grateful to you. Furthermore, you can also enjoy the beauty of swimming during the night. Do you hate insects? Me too. One of the reasons why I hate spring and summer is because that is the time when bugs, cockroaches, grasshoppers, and other insects are popping out. I am literally afraid of turning lights in the house on because I know that will attract butterflies, wasps, and other flying insects. That's why I thought swimming at night in your above ground pool is impossible. I mean, if you want to do so, you obviously need some lighting, and that will magnetize dozens of unwanted guests. However, I did not know that most of the pool lights are actually LED lights which do not draw the attention of insects. I am not sure why, but it seems like insects are very picky when it comes to light. This is a really great characteristic of pool lights. No one wants to share their pool with wasps, flies, spiders and other disgusting and "dangerous" little animals. You can not swim if you do not see anything in front of you. It may be very dangerous to take a bath in the total darkened pool. You can easily slip and hurt yourself pretty bad. I assume that's one of the reasons why my parents did not allow me to experiment with this kind of fun. Therefore, lights can provide you safety and thanks to them you will feel more comfortable as you wo not have to worry whether you will stay on some slippy surface, or something similar. Plus, the world is a dangerous place, and I really never feel comfortable in darkness in open space. That's why you should consider buying one of those lightings. Have you ever wanted to be on the other side of screen swimming in the romantically lightened pool with a hot partner? Well, you can actually do it with little help of the adequate and best above ground pool light. There are numerous options when it comes to pool lights, and many of them offer you the possibility of changing light colors. So, you can transform your ordinary pool into a romantic place for a perfect date in just one second. It's only up to you how you are going to use that possibility. Anyway, one thing is sure; pool lights can make magic real. You probably heard so many times that you should not mix water and electricity. Being inside of water that is connected to an electric source is life-threatening. So, you probably think that having pool lights is not so good idea. But, above ground pool lights producers thought about everything. Pool lights are completely safe, and they cannot interact with the water anyhow. Unlike ordinary bulbs, pool lighting bulbs are made to not cause any threat to you or anyone else in your pool. Also, they can not even interfere with your filter systems, so once again, you are completely safe. They have many advantages over standard lighting The most logical question is why anyone should buy this specialized lighting instead of ordinary lighting bulbs. Well, above ground pool light is designed to be more effective, economical and, as I said, safer. Also, I mentioned that pool light does not attract insects while standard lighting does. Another great thing with pool light is that most of them are made to be very durable, so customers do not have to think about batteries a lot. 5. Intex Multi-Color LED Pool Fountain for Above Ground Pools, Fits Metal Frame and Ultra Frame Pools Intex Multi-Color LED Pool Fountain is designed to make your pool look like a real fountain, as the name suggests.

That's why I feel such relief when I know it's safe, and you can freely use it near the water. What are the customers saying? One of the satisfied customers said that they were pleasantly surprised by how well it worked out for them.They were a little skeptical of how well this product would light up the pool given some other reviews and pictures they had seen. They were, however, pleased to see that they worked well on their 18-foot easy set pool. They had not had them very long so they could not speak to how well they will last long-term, but so far, they were working well.

It has 3 AAA batteries (not included) 16 static color modes and 3 dynamic color modes. It also has four remote controllers so you can control these lights from 30 feet distance. This product is really a very good solution for above ground pool light. It's a high-quality product, it's cheap, and you can use it literally for anything. It comes with 4 devices and 4 remotes. So, you can pick the best combination that fits your pool the most. I really do not have to tell you how much remote control is useful. You can sit back in your sunbed and change modes. And if you get bored of using this light only for your pool, you can use it for anything else. Unfortunately, you need to buy batteries on your own, and that can potentially cost a lot in the long run. But that's the price for a low price (what wordplay). What are the customers saying? One of the verified customers on Amazon said that this product works fine as long as you follow the instructions. The product package mentioned not to keep them submerged for more than 10 hours. That was the simple rule he had to maintain and he enjoyed his pools during nights as well. Intex LED Pool Wall Light is magnetic light that can be used only on pools that do not have a metal frame. It also can float in case that device separates from the magnet. These pool lights for above ground pool is the highest-rated and one of the best above ground swimming pool lights. That surely means that you will get what you expect from such a device. It has more-less whatever any other above ground pool light has. In addition, its possibility of floatation after separating from the magnet is very useful. You do not need your light to fall below the top of the water, even though it may be cool. What are the customers saying? A verified customer on Amazon described this product as one of the great products. He said the strong magnet keeps the lights at one place and it illuminated the pool beautifully. The only inconvenient thing was that there was no on/off switch so he needed to unplug it when he was done using it. Not a deal breaker but something that could be improved. He was still very happy with the light and would definitely purchase again. He like the above ground pool lights color changing. This Above Ground Pool Light is also multipurpose and it features five modes (Motion sensor low light mode, a Motion sensor (power saving mode), Always lighting mode, Automatic mode, and Emergency light mode). It has 60 LED Solar Lights. It is designed with PIR Motion which reacts to any movement within 16-32 feet long area. As it is Solar Light, it does not require any electric source. This is one of the best above ground pool lights. It can do anything. Whatever you want from pool light to do, this device is able to accomplish. Also, it does not have any particular drawback and that is a big bonus. The fact it is Solar Light is both benefit and disadvantage. First of all, it will save you the money you would spend on electricity. But on the other side, it can not work without Sun, so if you live in areas with cloudy and rainy weather, you maybe should avoid buying this thing.

Basically, it will work only when you pass by the ECHTPower Solar Light device. That's like a device that is smart and intelligent and knows when you are nearby.

Importantly, challenge-response pairs differentiate our protein-based PUFs from other common unique objects and tags29,63. In reaction to optical challenges, defined by a unique set of excitation and emission bands of different fluorescent proteins, the edible PUF made of silk protein (i.e., fibroin) and fluorescent proteins generates distinct output responses, which are used to extract digitized keys (Fig. 1a). The source of entropy is randomly distributed fluorescent silk microparticles seamlessly embedded in a covert thin transparent silk film. First, we take advantage of four different fluorescent proteins (i.e., eCFP, eGFP, eYFP, and mKate2) that have specific excitation and emission peaks in the visible wavelength range (Supplementary Table 1). Specifically, we utilize fluorescent protein-expressed silk produced by transgenic silkworms as recombinant proteins via the piggyBac transposase method (Supplementary Methods and Supplementary Fig. 1a). Silk proteins are an excellent biopolymer to be genetically hybridized with fluorescent protein genes46,55,57,59. Second, to fabricate fluorescent silk microparticles (Supplementary Fig. 2), fluorescent silk fibroin is regenerated into an aqueous solution with a low-temperature process, is freeze-dried, and is gently ground into zeolite-shaped microparticles with sizes of 99.3 7.9 m (mean standard deviation) (Fig. 2a, b and Supplementary Fig. 3). Third, an admixture of the fluorescent silk microparticles is broadcast on a large flat surface and a white silk fibroin solution is poured on top. After an ambient drying process in the dark, this thin transparent silk film with a thickness of 150 m is punched into 7 7 mm2 squares, resulting in all protein-based edible PUF devices (Methods and Supplementary Figs. 2 and 4). eCFP, eGFP, eYFP, and mKate2 silk cocoons possess bluish, greenish, yellowish, and reddish colors under white light illumination (Supplementary Fig. 1b). However, after the regeneration of the fluorescent silk, each type of fluorescent silk microparticles are not distinguishable in the naked eye, while maintaining their fluorescent properties (Fig. 2 and Supplementary Fig. 5). This fabrication process is scalable for mass production without using any sophisticated equipment and is safe for oral consumption without any organic solvents or synthetic polymers (e.g., methanol, ethanol, isopropanol, or polyvinyl alcohol) (Methods and Supplementary Fig. 6a). Analyses of mass spectroscopy, energy-dispersive X-ray spectroscopy, and in vitro cytotoxicity (cell viability test) assays support the overall nontoxicity of the edible PUF devices (Supplementary Methods and Supplementary Figs. 7-9). In Fig. 3, the flow diagram illustrates how a cryptographic key is extracted from an output response when challenged by a set of excitation and emission bands, including the raw output measurement, the bitstream extraction, and the final digitized security key. We mainly use four representative challenge-response pairs (n = 4) based on the excitation and emission peak wavelengths of the individual fluorescent proteins in silk (Supplementary Table 1 and Supplementary Fig. 1c). An input challenge (C ) is selected as a combination of the excitation and emission bands at specific wavelengths such as = 415 nm and = 460 nm; = 470 and = 510 nm; = 470 and = 560 nm; = 530 and = 630 nm, corresponding to eCFP, eGFP, eYFP, and mKate2 in silk, respectively. Upon optical excitation, a raw fluorescent image is recorded by a charge-coupled device (CCD) camera equipped with a conventional zoom lens via a tunable color filter (Methods and Supplementary Fig. 10a). In other words, the corresponding fluorescent image acts as an output response (R ). A resultant digitized key (K ) is obtained by an extractor that converts the fluorescent image of silk microparticles to a binary bitmap (Fig. 4). First, to improve the quality of binarization, we normalize the raw fluorescent image (300 pixels 300 pixels) by the maximum intensity (Fig. 4a). The noise is removed by applying a threshold of 20%. Fluorescent areas smaller than a specific pixel size of 20 are also considered as noise. Then, the image is resized to be 150 pixels 150 pixels with a binning process. Second, to ensure a low bit error rate (high reproducibility), we find the spatial peak position of each fluorescent silk microparticle where the highest intensity peaks of the microparticles are located, subsequently reducing the image size to 50 pixels 50 pixels (Fig. 4b). Then, the peak positions are only assigned to 1 bits and other pixels are 0 bits. Third, to remove the bias of 0-bits, we apply an enhanced version of the von Neumann bias compression algorithm with two-pass tuple-output debiasing (Fig. 4c)64. Because the fluorescent peaks are relatively rare events in the entire image due to the density of the fluorescent microparticles, global bias is present such that 0-bits are generated consistently more often than 1-bits. Finally, after debiasing, we use first 64 bits as a digitized key in each response, because a typical minimum number of peaks in the fluorescent images is 32. Combining four challenge-response pairs (n = 4) together, the final digitized key size results in 256 bits (=4 64). We assess the quality of randomness of the edible PUF-generated binary sequences, using the NIST statistical test suite that was originally designed to evaluate random and pseudorandom number generators65. One of the minimal requirements of PUFs is randomness with high entropy, as PUFs rely on an entropy source to create an unclonable output response66,67. When PUF responses are used for cryptographic key generation, it is also critical to evaluate the randomness to ensure the unpredictability of the keys generated by PUFs. The NIST statistical test suite includes 15 different tests to quantify the randomness of bitstreams. Each test focuses on a specific aspect of randomness (Supplementary Table 2). Some of the tests rely on the minimum sequence length of 1 106 and the minimum number of substrings (blocks) of 55, requiring a total stream of 5.5 107 bits. On the other hand, the key size of the edible PUFs is significantly shorter than those of random number generators. To use seven statistical tests that require a reasonable stream length, we explore the randomness of binary sequences summed from 30 different PUFs (Fig. 5). Specifically, we collect a total of 7680 bits from 30 different PUFs (256 bits for each PUF) and divide the bitstream into 60 sequences to perform each statistical test 60 times on individual 128-bit long sequences (Supplementary Dataset 1). Each statistical test returns two results; a p-value of a chi-squared (2) test and a pass rate (i.e., proportion), as shown in Table 1. As summarized in Table 1, the binary sequence from the 30 different PUFs passes all of seven NIST randomness tests without any post-processing. The parameter values used in each test and the characteristics of the NIST randomness tests are summarized in Supplementary Table 2. In other words, the bitstream (7680 bits) extracted from the 30 PUFs is statistically random, supporting the idea that the output responses of all protein-based PUFs can be unpredictable and unclonable. This result also supports the idea that our simple broadcasting process of particulate fluorescent silk offers a random spatial distribution as a straightforward yet effective entropy source60,61. To evaluate the basic PUF performance, we examine the digitized keys of the edible PUFs. We first estimate the bit uniformity by checking the equal probability of observing 1-bit or 0-bit states: where K is the lth binary bit of the key and s is the key size. Basically, the bit uniformity is the Hamming Weight (i.e., number of 1 bits in a binary sequence) of the s-bit key. For 30 different PUFs, the distribution of bit uniformity converges to the ideal value of 0.5 (Fig. 6a). Then, to evaluate the device uniqueness of each PUF, we calculate an inter-device Hamming Distance (HD) by counting a number of different bits between two PUFs under the same challenge. The device uniqueness measures the degree of correlation between digitized keys measured from two different PUFs. Ideally, the digitized keys from any two selected PUF devices should be uncorrelated, indicating that the state of a PUF is unknown even when the states of other PUFs are known. The inter-device HD between any two PUF devices can be defined: where K and K are s-bit keys of the ith PUF device and the jth PUF device among q different PUFs, respectively. The 30 different PUF devices generate a total of C (=30 29/2 = 435) comparisons. In Fig. 6b, the histogram of the normalized inter-device HDs is well fitted into a Gaussian distribution with a center at 0.5032 with a standard deviation (SD) of 0.0458, which is close to its ideal value of 0.5, exhibiting the excellent device uniqueness of all of the edible PUFs. In addition, we investigate the degree of correlation among the digitized keys of four responses in each PUF by calculating an average HD (Fig. 6c). The 30 different PUFs result in a mean HD value of 0.499 with a SD of 0.0041, indicating that the individual digitized keys in each PUF are also unique. When the number of challenge-response pairs is extended to seven, seven resultant digitized keys are still uncorrelated with a mean HD value of 0.5089 with a SD of 0.0766 (Supplementary Figs. 11 and 12). In addition, we calculate an encoding capacity of the edible PUF-generated binary sequences. The encoding capacity simply means a number of codes that can be generated and is defined as cs where c is the bit-level (c = 2 for binary bits of 0 and 1) and s is the key size38,68. To accurately estimate the encoding capacity, it is important to use an appropriate key size. When an imaging scheme is used, one may think that the total number of pixels (variables) is the digitized key size. In this case, the actual encoding capacity can be less than this nominal encoding capacity, because each individual pixel (variable) cannot be completely independent. One way for estimating the number of independent pixels (variables) is to analyze the degrees of freedom; s = p(1 p)/2, where p is the mean probability and is the standard deviation31,34. In Fig. 6b, the resultant width of the inter-device HD distribution shows that significant subsets of the key are mutually independent, corresponding to the degree of freedom (or number of independent variables) of 120 (0.5032 (1 0.5032)/0.04582). As a result, the edible PUF has c = 2 and s = 120, resulting in a relatively large encoding capacity of 2120 (1.3292 1036). Importantly, the debiasing process is useful not to comprise the actual coding capacity. If a security key is biased with too many 0 s or 1 s, the actual coding capability is often diminished. A large encoding capacity could be utilized to provide information on manufacturer-determined data, including dose information (e.g., dosage strength, dose frequency, and expiration date), manufacturing details (e.g., location, date, batch, and lot number), and distribution path (e.g., country, distributor, wholesaler, and chain). If a higher encoding capacity is required for a specific application, the key size of our edible PUF can simply be scaled by further optimizing the density of fluorescent silk microparticles, which allows for a larger number of peaks in each image. The number of challenge-response pairs can also be increased by incorporating additional combinations of the excitation and emission bands (Supplementary Fig. 11). To examine the feasibility for reliable PUFs, we test the readout reproducibility and stability of the security keys from the identical PUF device. The reproducibility of a PUF represents the ability of generating the identical keys following the same repeated challenges. We calculate an intra-device HD, which is quantitatively described by a bit error rate (i.e., percentage of error bits out of response bits with an ideal value of 0) from 10 challenge-response cycles (nine pairwise comparisons) for each PUF device. For the ith PUF device, an average intra-device HD captures the readout reproducibility: where K and K are the original s-bit reference key and a s-bit key extracted from the same PUF device at a different time-point t and m is the number of repeated measurements. Figure 6b shows a relatively low mean value of 0.0632 with a SD of 0.0164 estimated from the intra-device HD histogram for the 30 different PUFs at the same 10 challenge cycles. We further examine the long-term reliability under the same challenges after 60 days in the laboratory environment (i.e., stored at 22 2 C and 40-50% relative humidity in the dark) (Supplementary Fig. 13). When the fluorescent intensity of the raw fluorescent images taken 60 days apart is compared, the correlation coefficients (r) of the four responses (R , R , R , and R ) range from 0.833 to 0.983. For the pixel positions of the first 32 peaks in the binarized images, the r values are even higher than 0.895 for all of the responses. These results support the potential reliability of the protein-based edible PUFs, although the reproducibility assessments do not reflect extremely harsh conditions, given the medical applications. We further estimate a false positive rate and a false negative rate from the inter-device and intra-device variabilities. When PUFs are used for authentication, the false positive rate is the probability that PUF A is authenticated as PUF B. The false negative rate is the probability that a correct PUF fails to be authenticated. The resulting false positive and false negative rates are 9.6394 1013 and 3.0982 1012, respectively, assuming that the inter-device and intra-device variabilities follow Gaussian distributions (Supplementary Fig. 14). The pairwise comparison map of cross-HD analyses further shows that all of the 30 different PUFs are highly uncorrelated (Fig. 6d) where the diagonal line indicates the intra-HD values for the identical PUF device itself, while the off-diagonal points represent the inter-HD values compared with the other PUF devices.
Leapfrogging to a Renewable Future.
The devastating typhoon that hit Mozambique in March 2019 gave terrible support to the widespread expectation that poorer nations will suffer from the impacts of climate change most. The reasons include poor infrastructure, the absence of social safety nets, limited financial resources, and often tenuous public order. Poor rural dwellers depending on subsistence agriculture can not count on crop insurance or government bailouts. Floods and storms add to the pain from water and insect-borne diseases, which are likely to increase and spread to new areas.As the challenges from climate change mount, building resilience to its negative impacts may be more important than trying to get the world's poorest nations to cut back their emissions. The nations of Africa, in particular, have contributed little to anthropogenic climate change, and it's quite possible that Africa will move forward with continued low emissions, especially in the realm of electrification. Climate Change and Renewable ElectrificationAfrica has the opportunity to leapfrog the carbon-intensive centralized development process and move straight into distributed electrification — especially through on and off-grid solar and wind power. The International Renewable Energy Association (IRENA) estimates that 60% of Africa's electricity needs could be met through renewable off-grid solutions.Indeed, the majority of renewables development is now taking place in non-OECD countries. In 2017 this amounted to 94 GW of installed wind and solar globally — twice what was built in new coal plants that year.As electricity continues to spread, Africa would surely benefit from its own green new deal. But there's a real need to develop a trained workforce to fill the gap in skilled labour in the clean energy sector, to take on the skilled work of developing, building, and maintaining solar and wind projects, microgrids, and storage and local distribution systems, for the hundreds of millions of Africans who still lack access to electricity. Of course, as electrification penetrates further, it opens up many more new opportunities in a wide range of businesses, including IT, communications, and remote work.To now, most renewables development has taken place in wealthier African nations like South Africa, Kenya, and Uganda, and most commerce is happening in the cities, again among wealthier Africans. Not surprisingly, business is going where the money is. According to Gogla — the global association for the off-grid solar energy industry — most sales of off-grid lighting are similarly concentrated in Kenya, Uganda, Ethiopia and Rwanda.That means that for now the poor rural populations are largely left out, even while they could benefit most from even the most basic of off-grid technologies like lighting. Gogla notes that families with solar systems very often see an increase in income, while small businesses find new opportunities for efficiency and customer service. In addition, solar powered lighting expands opportunities for income generating work and education at home.Local clean energy systems can also help build individual and community resilience, particularly by providing water for drinking and irrigation. And they have a positive impact on health and cleanliness, by reducing indoor air pollution from kerosene lamps and improving access to clean water, communications, and health care. Putting the Leap in Leap-FrogSo the question is, how are poor communities going to gain access to these beneficial technologies? How are they going to be financed and built? And how can this be done without imposing the trappings of multilateral debt and the spectre of privatization, austerity, and neocolonial exploitation? How, that is, can the world's poor reap the benefits of an autonomous energy modernization leap-frog?Well, businesses are not entirely asleep at the wheel, and the growth of pay-as-you-go has gone a long way to proving the benefits of clean, modern energy. Gogla represents 130 firms, most of which it seems are using a PAYG model. PAYG grew at an average annual rate of 140% between 2013 and 2016, and was the model used with 80% of solar home systems sold in 2016, according to the World Bank statistics. But the very poor are still generally seen as too high-risk, and high cost (i.e. in reaching scattered rural villages) to be attractive for traditional entrepreneurs. These markets are often left to charities like Solar Aid, founded in 2006 to provide access to solar lights in Uganda, Malawi and Zambia, and to help catalyse solar markets and eradicate the kerosene lamp. SolarAid's charity work is largely educational, and the corresponding high cost of sales is what turns for-profit companies' attention elsewhere. SolarAid's "teams travel thousands of miles — spending days with local community members — sometimes only selling a handful of lights. Because that's what it takes to help people leave the darkness behind. "Another novel approach is SolShare, a Bangladeshi start-up that is developing local micro-grids "from the bottom up," to enable the 3-5 million solar-powered homes there to trade electricity, even with neighbours who do not have their own solar panels. This a truly localized peer-to-peer trading within the "last mile" of power distribution infrastructure. The SolShare network also generates a potentially valuable set of data on production and consumption patterns, and on how such a trading system functions. AfricaGreenTec (see images) is another group that provides electricity — and with it, clean water and internet connectivity — to whole villages. The key is their portable Solartainer — a solar power plant that unpacks like a high-tech butterfly from its shipping container cocoon.While bringing all the benefits of distributed solar to some of the poorest and most remote communities on the planet, AfricaGreenTech, SolShare and others also hold the seed of a much bigger shift. The next leap: Data-Driven TokenizationFor some months I've been working with innovators at Freeelio, especially around TheSunProtocol and the Electraseed Fund. These projects are creating ways to expand rural renewable electricity, and make it self-sustaining, through the application of blockchain technology and the drive of data valuation.While SolShare and Africa GreenTec have shown how power can be provided, Freeelio sees an opportunity to use blockchain and the token model to build incentive structures that enable autonomous social development through a meritocratic token distribution. TheSunProtocol, for instance, not only sees tokens being used to purchase electricity, but also aims to reward consumers for their productive electricity uses — amplifying, if you will, the economic returns on their activity.TheSunProtocol token provides a redeemable means of exchange, as its value (in kWh) remains constant. The token can be separated from the electrical supply; users could use the tokens to pay for a haircut or groceries, while their merchants could then exchange the tokens for electricity. The token could even be used in exchanges between users in separate villages, thus building an economy of value harnessed from the sun itself. This would be a leap far beyond what typical development experts typically prescribe, and reflects a far more sustainable economic vision for the future — one in which environmental and social values are reflected in something like a Quality-Adjusted GDP.Such a leap requires a takeoff point, and for now, that means the hardware, the education, and the technology development, needs to be financed, and that demand falls on donors or investors from wealthier nations. How can it be made easier for such investors and donors to be part of these initiatives? One of the big and quite reasonable concerns of financiers is in ensuring that the money they invest is achieving the returns they set out to achieve, whether these be monetary, or in the social and environmental sphere (ESG). Smaller or distributed projects are less "bankable" in part because the money can be hard to track, and the returns difficult to measure and capture. They also carry some risk (not absent from larger projects) of money being misdirected or connected with criminal activities, especially if KYC regulations have not been followed through the entire flow of funds. It's here that the ElectraSeed Fund can allow blockchain and especially smart contracts to shine. As an energy data-driven investment platform, the ESF invests in a pool of solar energy assets worldwide. It too uses smart contracts to improve data integrity and transparency, and to thus open up the scope of positive impacts for donors and investors. ElectraSeed Fund smart contracts can track investment funds down to the individual user and kWh. They may even be able to characterize the use of the kWh — in other words, the specific sorts of activities the electrical gifts support.The Electraseed Fund is thus designed to enable investors to see precisely how their investment is performing, especially in the ESG calculus, even while the Fund pools investments across a range of projects to reduce risk. Companies that seek to offset carbon emissions, or that want to verifiably achieve targets within their own ESG commitments, can access secure data on the results on the ground, half a world away, in real time.The Electraseed Fund is building relationships with host-country entrepreneurs like SolShare, to help ensure local uptake and reliability. Meanwhile it's engaging with western firms looking to build their ESG returns, and that want to find ways to better validate their investments. Another interesting model, called Energy Solidarity Token, entails the western company donating cost savings achieved through energy efficiency measures to purchase electricity to give away through the SolShare model. This allows the firm to leverage its investment to achieve environmental and social goals where they are most needed.Blockchain and decentralized renewable energy constitute a major leap for electrification among the world's poor, but the path ahead is promising. While the footprint is still small, it suggests huge potential to improve lives in Africa and South Asia, where hundreds of millions still lack electricity.A leap like this might not ultimately do a lot to reduce emissions or slow climate change, but these initiatives can make a big improvement in the lives of the world's poor, who in any case need to figure out how to live under changing climate conditions. Electricity, clean water, and communications connectivity are key elements of a resilient local infrastructure, and a radical localization - not just of energy but also food, water, and economic and commercial infrastructure - may well be what it takes to ensure rural Africans and others can continue to create and produce, to thrive in the pursuit of their goals, and to grow with their families and their communities.

Leave a note in the forms for the research venture TheSunProtocol, pilot of Electraseed Fund, and Energy Solidarity TokenThe Advantages of Solar LightingLarge companies and homeowners alike enjoy the many benefits that only solar lighting can provide. Solar lights are ideal for areas that are off-the-grid, where energy is costly or if the company is looking to showcase their eco-friendly approach to energy. Installing solar lighting is considered one of the most cost effective projects to date as they do not require trenched grid power and the actual costs of installation are minimal. There are many ways to take advantage of solar lighting solutions. Some are as small or simple as a singular LED bulb or a solar lantern, while others are more advanced needing a battery and integrated panel. These lights are generally employed to light driveways or even 150′ spaces with floodlights. Solar is the best option when power is not available in a location or too costly to install. Using solar lights also eliminates concerns around a power surge. Of course, there are numerous advantages for choosing solar lighting over traditional methods. Great Way To Go Green! Solar power is the number one source of renewable energy; therefore, solar lighting is a great way to transition to going green. It takes absolutely nothing from grid power and is naturally produced. The LED lighting uses a battery that charges up on solar power during the day, and at night it dips into the power supply to illuminate the desired area. This is a process that repeats daily without using any other form of energy. Installation is considered low cost, in any case, lower than trenching grid power. There is no underground running conduit to the light poles like you would see with traditional power, however, poles, albeit much taller, are still employed in a safe manner. Installation is safe and not as difficult as it is considered low voltage power and the only wiring is located at the top of the poles. In some instances, it may carry across to nearby poles. Standard electric trenching is rife with difficulties, but that is not something experienced with solar power installation. The greatest thing about solar lighting is that it's virtually maintenance free. This is especially the case as LED bulbs last for 20 years or more. If properly installed, the system's batteries will need some maintenance only every 5-7 years. Visually checking and cleaning the glass grid is also recommended to prolong its lifespan along with checking the light fixtures themselves. Most other components can last 30 years or more without any maintenance whatsoever. The most convincing aspect of solar power is the ability to reduce energy bills to zero. Though a commercial system can cost a lot of money upfront, the savings by utilizing solar power will pay back dividends on this investment. In addition, commercial systems also receive significant monetary incentives to make the switch to solar energy. If you care about the environment and wish to reduce your footprint, solar lighting is a great option! It works just as well as traditional power while cutting your energy bills down to zero and providing a constant stream of LED lighting. Whether you have an expansive backyard or a large area in need of illumination, solar energy is here to help. Do you have other alternatives you like for your lighting needs? Just let us know as we would love to hear from you.
Solar Street Light Market Is Growing Globally
The solar street light industry is growing exponentially with governments and organizations across the country and the globe offering incentives for solar installation. In the United States over 200 city mayors and city managers have committed to going 100% renewable by 2030. This growth is also being fueled by the increasing cost of traditional fossil fuels such as coal and natural gas power plants while renewables are going down. Renewables just surpassed fossil fuels for the first time ever last month. The government of India is planning to replace 35,000,000 street lights and almost 800,000,000 incandescent light bulbs with LED lights.Solar installers say cost per kw-hr is total charge/kw-hr from elect. co., but why would elect co agree to free use of their grid?The electric company is probably already charging you a connection fee and for the average household, that fee should not depend if you receive, send power, or how much power you use.

In many ways, hiring a solar contractor is much the same as hiring a contractor to do any home project. Do not be intimidated by the technical nature of solar: if you do some due diligence and ask the right questions, you will be fine. This guide will help. Now what? How do you choose the best solar installer? Here's the tips that will help guide you to a good decision: Get in the right mindset We do not want to scare you or anything, but just be aware that buying solar is more complicated than. But it's also less work than remodeling your kitchen. So be prepared to do some work, but it's really not that bad. Just go into it with the right frame of mind. You are hiring a contractor. You will need to carefully review a contract and make a couple decisions, but not nearly as many decisions as if you were redoing your bathroom or kitchen. On the other hand, there are some companies out there that want make the home solar buying process a little bit like picking a flight or a hotel. We think that this is bad for the consumer for a number of reasons. First of all, this approach emphasizes price over other important considerations. It's okay to just go with cheapest option if you are , say, renting a car for the weekend - one company's Toyota Corolla is the same as a Corolla from any other. But solar panels are a product that are going to last you 25-30 years. Workers are going to come to your house and bolt a lot of equipment to your roof. It's a major purchase, so it's important to really understand the details of the product before you make such an important decision. Second, it encourages people to gloss over the important details of the equipment that you are buying. You might be prone to do this because solar can involve an intimidating number of technical aspects like watts, voltage, AC/DC, efficiency ratings, electric meters and monitoring systems. But, we promise, you do not need an engineering degree to figure this stuff out. So do not just make your decision on price. Consider the quality of the contractor and the contract details. Imagine that you want to do a big home renovation. You are going to make your dream kitchen! It's going to look just like the magazines. So you come up with a wish list of things that you want to have: shiny stainless appliances, granite countertops, a big island, wine fridge, that sort of thing. Oh, because you've got an older home where everything is a little bit crooked, you want the contractor to tear everything down to the studs and also install a new floor. Then you come across a website that promises to give you an accurate quote for all of this, just by filling out a form. No phone calls. No contractor will even come to your home to take a look around. Would you trust a quote like that? No, obviously not. If you are doing a kitchen remodel, a competent contractor needs to make a site visit so they can identify problem areas that will cause labor or materials costs to go up. Are there structural aspects to the space that will make the work more difficult? Is there electrical or plumbing work that needs to be upgraded? Is there a chance that your floor tiles have asbestos? All of these things would cause your estimate to go up, but none of them can be identified without a person coming to your home. Problems that cause solar costs to go up Solar panels and racking are heavy and last for decades, so a good contractor will need to evaluate the condition of your roof. Is the roofing material and decking in good condition? Do you have roof drainage issues that need to be addressed first? What is the size of your current electric service panel, and will it handle the additional load? Do wiring or circuit breakers need to be upgraded? Do you have landscaping that will cause shading problems after a few years' growth? Nobody on the internet can promise an accurate quote for your solar project if they do not come to your home to assess these kinds of things. A lot of people do not like sales calls. That's understandable. But for a project like a solar installation, you have to make an exception. In this case, you are going to get a phone call, and somebody is going to come to your house. This is a good thing. Get more than one quote Just like with your dream kitchen project, you need to get multiple quotes. This is not only to get a fair price, but also to compare the different materials, warranties, and credentials of the companies that you are evaluating. For example, one of the most important details of a solar installation is how the racking is secured to the roof and waterproofed. Ask the contractor exactly what methods and materials will be used. What is the fastening system, and what flashing and sealants are used to waterproof it? Or, maybe one installer insists that microinverters are the only way to go, while another contractor says that they would use string inverters for the project. In that sort of situation, you need to be prepared to ask each contractor why they selected one type of equipment over another. Never select a company only on price Everybody likes to save money, but do not save money on your solar photovoltaic system by simply going with the cheapest quote. There are real differences in equipment and installation quality . While it's very possible that your best installer will also be the cheapest, you can not know until you closely evalulate the details of the contract and materials. Conversely, going with the most expensive installer does not guarantee higher quality either. The biggest solar panels company installers, usually do not want to sell you a solar system. Instead, they tend to push you to rent one instead using financial products such as solar leases and power purchase agreements (PPAs). These financial products result in higher profits for them, and a lower financial return for you. There are a number of reasons why these financial products are often bad for consumers, but one of the key reasons is the inclusion of escalator clauses that automatically increase your cost of electricity every year, even if the utility company holds their prices flat. In addition, many of these large national installers have poor reviews and have even faced lawsuits by state governments. Prefer local companies that have been in business for a long time When you get a quote, we prefer local solar panels company that have been in business for a long time and have a strong presence in the community. Quite often, these are electrical companies that have decades of experience that have added solar installation to their portfolio. One reason is the obvious fact that a company does not stay in business for decades if they do lousy work. But the most important reason is that in order for a contractor to honor their labor warranty with you, they need to still be in business. The labor warranty, which is separate from a manufacturer's warranty, could be 5 to 10 years long, and even more with a few companies. With the explosive growth of residential solar across the country, a lot of new companies have sprung up overnight, especially in states like California. A company that has been in business for only a couple years might do great work, but running a company profitably for decades is a different skill than installing solar panels. Your best chance of having a company be around to service your system years from now is to pick one with a long track record. Be wary of brand new solar companies that have been in business for only a couple years. If you are independently doing research on solar installer companies, be selective about the review sites that you use. You will find sites, including ones that specialize in reviewing solar installers, that allow companies to appear as featured companies in their listings in exchange for a fee. This is a controversial practice , one we think that is misleading to the consumer. Which sites should you trust? Start with the BBB.org, which contains both reviews and a platform where consumers can file complaints with the Better Business Bureau, and companies are able to respond. Google Local Business is another site we think is reliable and does not offer paid placement. A few years ago, Yelp was accused of extortion , but the class action that followed was dismissed, and we think the company answered the controversy reasonably. Fake reviews are a different issue, and one that is more difficult to address. For this reason, we recommend you start with BBB, which uses human reviewers to check submissions. Check that your contractor is licensed The first thing to do is understand what type of license is required by solar installers in your state. The Interstate Renewable Energy Council maintains a website that lists what is required. Be aware that licensing for solar photovoltaic (PV) may differ from the requirements for solar thermal (which is used for hot water heating), so read carefully. Once you know what the requirements are, you can ask your contractor for their license so that you can look it up at your state's licensing board. California and Nevada, for example, make these databases searchable online, and also tell you how long the license has been active and whether the contractor is bonded. Check online to see what your state provides. Many companies list their license number right on their website, so you can do this check in just a few minutes. Never work with a company that is not properly licensed. There are many different components in a photovoltaic system, and each is covered by a different warranty from their manufacturer. It's crucial that the installer fully explain each one. The solar panels company should provide a warranty of the workmanship and components of the system, and cover the labor and replacement costs of any failing components. Photovoltaic panels have their own warranty, and often this is specified in two parts: one warranty covering materials and workmanship, and another warranty period covering their power output. Solar panels normally degrade over time, producing a little less power each year. (This degradation should be less than 1% per year.) The panel warranty will certify that it will continue to produce a given percentage of the original power output after a number of years. A 25 year power warranty is typical, and the product warranty should be at least 10 years and is sometimes long as 25. The inverter system is a critical part of the system, and will have its own warranty period. 10 to 25 years is typical. The racking system needs to hold up to potentially extreme weather for a couple decades. You want to make sure it has a strong warranty - at least 20 years. Are you getting batteries? It's a pricey component, so be sure you know what the warranty is. Meet your solar panels company contractor in person and ask a lot of questions We mentioned already that you should always have a face-to-face with your potential solar installer, right? Once you have an actual human person in front of you, that's the time to ask some important questions. Sometimes, the first person you meet with wo not be technical and can not answer all your questions on the spot. They might need to consult with other people on their team. That's okay. Just be sure that all your questions are clearly answered before you sign a contract. If you have not already checked that the installer has the proper licensing for your state, now is the time to do so. Also ask if their installers are NABCEP certified. What incentives are available? Use our calculator to find out about major incentives, but your solar installer may know about other local rebates. Be sure to understand if the owner receives the credits, or if the installer does and passes them onto the customer. Confirm if net metering is available to you, and make sure that you clearly understand how it works. (You can read our article What is net metering? for a primer. The estimate should list the price of individual components and labor: modules, inverters, racking, labor, electrical work, and other costs should be itemized. The contract should indicate exactly when payment is due, and what the payment schedule is (if any). You will receive a site plan that visually indicates the layout of the system components on your home, which includes the placement of the panels, inverters, disconnect switch, and meter. The installer will give you an electricity production estimate for the system in a year with average weather. Compare this with your average usage, and make sure that you are happy with the system output. Ask about labor and component warranties. Discuss the details of the solar panels, inverters, and racking system. Systems that are tied into the grid will require approval from the utility company, and possibly an inspection. Ask about the requirements and timeline of these. Your local code may require an engineering structural inspection before work begins, and an electrical inspection after work is completed. Ask what is required and when in the project timeline they occur. Your interconnected pv system will most likely require that your utility company install either a new bidirectional meter, or a second meter alongside your existing one. There may be a fee charged for this. Be sure to ask. Find out how you will monitor the system output. This will either be a display on the inverter, or a website or smartphone app. Ask if there is recommended system maintenance. If your roof needs repair, find out labor charges for removing and reinstalling the hardware. For component failures that happen after the installer's warranty, ask about the process for making a manufacturer warranty claim and having the component replaced.
