What Powers a Solar Street Light? the Same Thing That Starts Cars Every Day. Rechargeable Batteries!

The new kids on the block are starting to take the world by storm, and are only going to grow in popularity and efficiency. No, they are not a pop sensation of teens singing songs of growing up and high school sweethearts. The new kids are solar street lights that will bring energy production and dispersement directly at the site of the light itself. Solar street lights have come a long way since their piecemeal configurations of large solar panels and inefficient luminaires. Today, companies such as SolTek Renewables are working to supply customers across the globe with a new generation of area lighting that is on par and above the standards of conventional lighting methods. Their lights use CREE LED fixtures that are highly efficient, safe to use, generate minimal heat and produce illumination (in foot candles) that often exceeds traditional non-LED luminaires. With these positive aspects, the most cost-effective energy source to power LED luminaires is by employing sealed lead-acid gel rechargeable batteries, much like what is in most cars on the roads today. So, why use a lead-acid battery as opposed to a Lithium battery? First, the cost of lead-acid batteries is within the economic realm of most users. Their capacity is high for the size and initial investment, so they are the chemistry of choice for solar street lights. Being that the batteries are essentially car batteries (and comparatively priced), they are 95% recyclable and have a typical life-span of 5 to 7 years. Coupled with a smart controller that regulates the charge from the battery to the LED fixture at night, lead-acid batteries have a system autonomy of anywhere between 3 to 6 days (typically toward 6 days). This means that the solar panel will collect photons (light) from the sun in a span of 2 to 4 hours and charge the battery to capacity. At night, the light will illuminate with a steady discharge from the lead-acid battery as specified by the controller. If the following 3 to 6 days are occluded with thick cloud cover or stormy conditions, the battery will continue to operate as intended over the next 3 to 6 days until it needs the 2 to 4 hours of sunlight to get a full charge again. What does this mean for regions where sunlight is more likely to be out more than once every 6 days (realistically, how often, if ever, does that happen)? It means that illumination autonomy can be achieved by users/owners of solar street lights. It means that you are now 100% energy efficient with regard to generation and use. It means you are using 100% renewable energy. It means local energy generation, thus eliminating the dirty energy of coal and oil sources. It means savings for your local economy as you have eliminated fees incurred by local utility companies (they can raise the rates all they want, you are not paying a penny to them with autonomous street lights). It means it can happen now (2 months installation from factory to site). It means that you save money from the get-go as you have eliminated trenching and expensive wiring to the utility grid. Stay tuned for our next blog on the CREE LED luminaires that are used in the solar street lights from SolTek Renewables. Reliable, clean and effective lighting is here to stay.

1. Solar street lighting is a unique opportunity for sustainable recovery | Greenbiz

This article is sponsored by Signify. In response to the economic fallout from COVID-19, the European Union has formulated a major recovery plan for the continent with a key focus on adapting to the digital age and investing in cleaner and more resilient technologies for the future. In the U.S., the 2021 American Jobs Plan aims to steer $2 trillion into productivity and long-term growth, including a strong focus on building resilient and climate-friendly infrastructure. With economic and climate resilience plans taking a more concrete shape across the globe, Signify believes that solutions such as solar lighting pave the way for countries to build back better. According to Allied Market Research the global market solar energy was $52.5 billion in 2018 and is set to grow to $223.3 billion by 2026, vastly accelerating the scale of renewables. One of the fastest growing solar technology segments is street lighting. "Solar street lighting technology has come on leaps and bounds in recent years and is fully aligned with the goals of EU and U.S clean energy and economic stimulus initiatives. Just 15 streetlights can save enough electricity to power a home for a year," said Harry Verhaar, global head of government and public affairs at Signify. "Being a digital technology, it can be connected to sensors and be controlled remotely, enabling forward-thinking municipalities to leapfrog to solar and reap the benefits of the digital age." President Joe Biden's administration already has proposed $621 billion of additional investment in transportation infrastructure, with $20 billion earmarked to improve road safety and $174 billion for electric vehicles. A sizeable chunk of the latter would be spent on grant and incentive programs to build a national network of 500,000 electric vehicle charging stations by 2030. Signify advocates specifically for the wide adoption of solar and solar hybrid powered street lighting which will not only help improve road safety, but also pave the way to lower emissions and eliminate the need for extra power stations to power the street lamps. This is particularly useful in more remote areas where existing infrastructure is minimal. With the strain taken off power stations, excess capacity could be diverted towards supporting charging stations for electric vehicles. Solar is the ideal technology for serving far-flung communities with intermittent power supply or coverage. For example, in 2020, Signify installed solar streetlights on the Greek island of Leipsoi in areas lacking full electricity coverage including a playground, allowing the community to feel safer. A total of 28 autonomous Philips SunStay luminaires were used, each combining a solar panel, an LED light, a charge controller and a battery in one housing unit. The lights also contained an infrared motion sensor which detects movement and alters brightness accordingly, increasing energy efficiency and minimizing light pollution. "As we have many hours of sunshine throughout the year this is a very effective and functional solution for those areas on our island that are not connected to the power grid," said Fotis Mangos, mayor of Leipsoi. "The lights have such an aesthetic design that they seamlessly blend in with our island's natural landscape." The electricity grid does not always follow the street layout on the island and the solar installation allowed for an inexpensive, unobtrusive and environmentally friendly way to light roads and pathways without needing to dig trenches for electrical cables. "Solar lighting is a key part of our commitment to sustainability and to climate action, as we aim to help people move to cleaner technologies," said Signify's country leader for Greece, Polydefkis Loukopoulos. "The expansion of solar lighting in new areas of Greece strengthens our vision to provide local communities with the security that results from high-quality solar lighting." With the addition of hybrid technologies, solar lighting is a feasible solution in areas with only seasonal sunshine, allowing countries at higher latitudes to access its benefits. This technology broadens the market for solar power. A version of solar is available beyond sun-soaked countries to around 6.5 billion people in the world. According to Antonio Espada, head of public segment in Europe for Signify, solar hybrid street lighting is the best of both worlds. It uses sunlight to charge its batteries and on cloudy days seamlessly switches to electricity from the grid. It's highly energy efficient and increases the use of renewables and balances electricity loads. The battery power can be used during peak hours so fewer power stations are required. "Solar and solar hybrid power streetlights are particularly well suited to countries and regions where power outages are common. It can help deter crime and contributes to safer, more resilient communities," added Verhaar. Ultimately, solar lighting is an accessible, efficient and future-proof solution for community development, and one which could hugely benefit global recovery on both sides of the Atlantic.

2. The solar street light is not bright, what is going on?

The installed solar street light is no problem. It will not be easy to light up for a while. It is necessary to check the indicator light of the controller first and see the status of the indicator light of the controller to identify the shortage. If there are 2 indicators If it is not bright, the controller will be damaged early, and the system will be destructive to strong current values, such as lightning or short-circuit faults. 1, The light source is damaged Due to the natural environment or the cause of the human error, the light source is damaged, resulting in the solar street light system not working, when the light is not bright, flashing, etc. Solution: Check the light source or replace the light source. 2, Solar photovoltaic panel damage Connect the digital multimeter to check the working frequency when the solar photovoltaic panel has no load. The general system working voltage is 12v, which is generally higher than the 12v working frequency. Only when the working frequency is higher than 12V can the battery be charged. 12V cannot charge the battery. The solar street light system cannot work or has insufficient working hours. Solution: Disassemble the solar panels. 3, The solar photovoltaic panel positive and negative plugged into the wrong After the solar garden light reinstalls the system, it always lights up once. When the battery is used up, the solar garden light is no longer easy to light up. Solution: Replace with the positive and negative electrodes of solar photovoltaic panels. 4, Battery damage Connect the digital multimeter to check the working frequency when the battery is not loaded. The general system working voltage is 12.8v, which is generally higher than the 12.8v working frequency. If it is lower than 12.8V, the battery explosion-proof switch can not be charged and discharged. The solar street light system cannot work or has insufficient working hours. At this time, everyone must use the charging plug to charge the battery. If the battery does not charge enough power, be sure to remove the replacement battery. Up and down is the reason and the treatment method of the relevant solar garden light is not bright. To solve this, to ensure that the natural light garden light is no problem, the punctual solar power circuit lamp manufacturer maintenance inspection is essential. As a professional manufacturer of solar-powered circuit lights, we will provide consumers with a permanently free service to provide maintenance and repair services for consumers. Details of the baby-related to the solar garden lights.

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.
Industry: LED Industry Reshuffle Through Three Forces
Industry: LED Industry Reshuffle Through Three Forces
The collapse of small and micro led enterprises last year has opened the curtain of the reshuffle of China's LED industry. Since the beginning of this year, three major factors, such as the rising threshold of government procurement, the continuous tide of IPO listing and the introduction of industry standards, will accelerate the process of reshuffle in the LED industry.On March 20 this year, the "2012 financial subsidy promotion project for semiconductor lighting products" organized by the Ministry of finance, the national development and Reform Commission and the Ministry of science and technology held a domestic public bidding in Beijing, involving led downlights and reflective self ballasting LED lights for indoor lighting, LED street lights and led tunnel lights for outdoor lighting, Nearly 300 bidding representatives from 110 enterprises across the country participated in the bidding activities.The national development and Reform Commission made it clear that in 2012, the Chinese government will spend 40 billion yuan on the procurement of LED street lamps and provide 30% financial subsidies to LED street lamp users. Since March this year, all lighting projects and new planning areas invested by the provincial government have used LED electrodeless lamps in the field of public lighting, which is estimated to bring a market of hundreds of billions of yuan.Don't think that the government will "sprinkle pepper" again. An entrepreneur who participated in the bidding on March 20 revealed that the national bidding raised the threshold. For example, products should have energy-saving certification. The province also invited tenders for LED products entering the indoor lighting of public works this year. So far, downlights of 3 enterprises, spotlights of 3 enterprises, bulb lamps of 6 enterprises and fluorescent lamps of 22 enterprises have won the bid.Facing the industry pattern of "small and scattered", the government began to realize that it is necessary to support powerful enterprises to become bigger and stronger.More and more led enterprises are listed, which will become another important force for industry integration. After development in recent years, the total number of Listed Companies in the LED industry has been close to 40, and not a few are lining up for listing. It is expected to produce some industry leaders who can compete with international giants.According to the data of provincial Lighting Appliance Association, from 2010 to now, more than 100 LED projection lamp enterprises have completed the share reform, and the Pearl River delta accounts for 51.5%; The listed led enterprises account for about 61.5%, including Hongli optoelectronics, Zhouming technology, etc; There are also some ready to be listed, such as Shenzhen Jiawei Co., Ltd., which exports solar LED outdoor lights for 1 billion yuan a year, and will be listed soon.After the listing of led enterprises, it is not only conducive to establish their own good brand image in the chaotic market, but also can use capital means to acquire and merge, expand themselves and purify the market. Zhouming technology said that if it encounters a good project, it does not rule out the possibility of acquisition.The third force of integration comes from the continuous improvement of industry standards. The national standardization management committee recently held the first working meeting of the semiconductor lighting standard leading group, involving the national development and Reform Commission, the Ministry of science and technology, the Ministry of industry and information technology, the Ministry of housing and urban rural development, the Ministry of Finance and other departments. This is the first time that the industry has uniformly planned and deployed the semiconductor lighting standardization work at the national level Light source and lamps, lighting application and energy efficiency.The Provincial Department of science and technology will also announce the progress in the formulation of semiconductor lighting standards this week. At present, 130 standard items have been listed, and led enterprises can participate in the revision of industry standards through bidding.It can be predicted that with the gradual improvement of industry standards, the LED metal halide lamp industry will bid farewell to the mixed situation. In the upcoming 12th Five Year Plan for semiconductor lighting, the state pointed out that by 2015, the scale of semiconductor lighting industry will reach 500 billion yuan, and cultivate 20 30 leading enterprises with independent brands and independent intellectual property rights, and 40 50 innovative high-tech enterprises
I Would Like to Ask What Are the Ways to Improve the Brightness of Solar Street Lamps?
I Would Like to Ask What Are the Ways to Improve the Brightness of Solar Street Lamps?
I would like to ask what are the ways to improve the brightness of solar street lamps?1. Determine the brightness of LED solar street lamp before purchaseBefore purchasing solar street lamps, if it is a large number of recycling, the best thing is to choose manufacturers with industrial plants and drive to the processing plant to have a look. If you decide where to buy, you must talk to the other party about the regulations on chromaticity. If you don't have much definition of this chromaticity, you can let the other party make a sample to have a look.If the requirements for chromaticity are very high, the size of LED light source should be larger. Some manufacturers will choose the most suitable scheme for you out of your own consideration. If it is not particularly bright according to your specific situation, you can also listen to the manufacturer's suggestions.2. Lower the LED solar street lamp equipmentIf solar street lamps are to be installed on both sides of the road, we should fully consider whether there are green plants on both sides of the road. Because the solar street lamp is converted into electromagnetic energy by digesting and absorbing solar energy, if something blocks it, the actual effect is undoubtedly impossible to be very good. When such a situation does occur, why not reduce the height of the solar street lamp and not completely cover the solar panel.3. Query LED solar street lamps on timeMany solar street lamp projects are not easy to hold meetings after the equipment is good, which is naturally not very good. Although solar energy does not need maintenance or cleaning by full-time personnel, it must be queried on time. The damaged position should be repaired immediately. If the solar panel has not been removed for a long time, it also needs to be inadvertently scrubbed.

This Can Be Done When the Solar Street Lamp Cannot Work (I)
This Can Be Done When the Solar Street Lamp Cannot Work (I)
1 Power loss of solar street lamp: the power loss of solar battery is due to the quality problem of the battery itself. The cheapest one is 2-3 yuan 1Ah. Generally, this is not very reliable. Problems continue to occur after using it for about a year. Therefore, to solve this problem, replace the solar battery and replace it with a better manufacturer, If it is a northern city, it should also be noted that the battery must be buried below the frozen soil layer, especially in cold places. Thermal insulation cotton should be added to the battery, because the capacity of solar energy storage battery has a great relationship with the external ambient temperature.2 The LED light source of solar street lamp is not on: it may be the most direct way for the performance of solar street lamp. The solar street lamp system is abnormal, that is, it is not on. One of the reasons why the solar street lamp is not on may also be the problem of LED light source. As a general purchaser, it is difficult to distinguish high-power LED light source. If the solar street lamp is not on, You can simply check the light source by yourself. If the system is small and the system voltage of the light source is 12V or 24V, the conventional configuration is used. The best way to detect the light source is to connect the battery directly to the light source. If the light is on, it proves to be normal.For more questions, please click the right figure to consult online customer service.
