Rated 5.00 out of 5 based on 3 customer ratings Rated 5.00 out of 5 based on 3 customer ratings With growing concerns on electricity shortages and keeping in view high fares, Ultronics has introduced Solar Street Lights with 60 Watts power. This solar street light is a complete solution for people choosing to move on alternate energy solutions. This solar light is built with high quality ABS Material that stands tall under tough conditions. An ideal selection for housing societies, parks, factories, mines and open warehouses this light is IP65 certified which means it is completely water proof. Back up Time: 6-8 hours (on full mode) when charged under bright sunlight1. how can i made a circuit for solar street light?You could be using leds or a compact fluoro for this. These will be for use with a 12V battery. It may be you want to reconsider using 40W, as less power is much more feasible. About 10W of CFL or LED supply will be the same as a 40W incandescant lamp, and last much longer. If using leds you will need an efficient switch mode current regulated source to drive them. You can expect similar efficiency to a compact fluorescent lamp. The leds will need heatsinks. The size of the battery and the panel are critical parts of the design. The power supply would be a 12V battery. The light runs at night only. WIth some care the solar panel itself can be used as a sensor to switch on the lights by measuring the battery voltage. When under charge it will be around 13.85V, using a float charger. The current is inherently limited by the panel. A simple but effective charger is to connect the solar panel by a switch (P channel mosfet as a high side switch or relay) when the voltage is below 13 volts and disconnect it when the voltage approaches 14V (lead acid battery). Use a reverse blocking diode with the panel. Note that gel type batteries are not very suitable for operation in sunlight in the tropics at least. When the battery is below 12.6V consider it as night time. Otherwise use a separate sensor for sunlight. Thus you have three voltage comparators for these 3 voltages. These can be a schmidt trigger with the correct hysteresis. You need a reference supply. A small 5V regulator is simple. This uses a solar panel designed for charging a 12V battery, meaning it has 36 cells. The OC voltage at standard conditions is 22V. Look up data sheets specs for panels. If the lamp runs 12h per day, and the power is 10W, then it uses 120Wh per day. With a 12V system this is 10Ah. The battery needs to be at least 10Ah, especially considering overcast days, and the need to not discharge it below 50% of capacity. This looks like a 40Ah battery therefore. The maximum charge rate should not exceed 4A (10h rate). The solar panels must provide 10Ah per day too, but... The battery takes 140% of its discharge to recharge, so now 14Ah per day. Allow extra to catch up after a period of overcast weather, at least 20Ah per day. The rated current occurs with full sun. There is an equivalent of full sun hours for your region, likely 2-5h a day. In the tropics 5h per day. Thus we need 20Ah in 5 hours, so a current of 4A. This agrees nicely with a 40Ah battery. So for a 10W lamp operating 12h a day in the tropics we need something like a 40Ah battery, and a 4 amp x 36 cell panel. This will be rated around 15V * 4A = 60W. A bigger panel is ok within reason, but should have a bigger battery so it does not charge too quickly. A bigger battery may be needed to increase the lifetime, and allow a reasonable number of days without sun if overcast weather lasts more than a day or too. The electronics should all be designed for outdoor use, vermin proof, including rats to ants, weather-proof and able to operate at 60C ambient temperature. The link below has an example of a P channel mosfet high side switch driven by a voltage comparator. Use a 10A or more rated switch and the comparator needs a reference so it turns on at 14V and off at 13V.2. All in One Solar Street Light Manufacturer with Best Price in IndiaAll In One Solar Street Lights All In One solar street light is a new-age form of lighting solution integrating solar panels, charge controller, LED light and battery. These lights are available in two varieties, with infrared motion sensors and without, as part of the unit. All In One solar street lights are becoming popular due to their compact design and multiple other advantages. Motion sensors help to adjust the LED brightness intelligently in All In One street lights. Infrared (IR) and passive infrared (PIR) motion sensors are used for motion sensed detection of emitted/reflected infrared energy. The All In One solar street lights with motion sensor switch on in the evening and after a time delay of 30 seconds, the lights automatically reduce their brightness to 20%. Motion sensor is capable of detecting infrared waves that radiate from moving objects, thereby electronically increasing the brightness of the lights. Once motion is detected, there is 100% brightness and if there is no motion detected in the area after the time delay, the light gets automatically adjusted to a dim mode of 20%. The biggest advantage of solar street lights with motion sensors is that they add a sense of security and safety to your property while providing better battery life. Features of All In One Solar Street Lights Controllers used in All In One solar street lights PWM or MPPT charge controllers are used in All In One solar street lights. PWM controller acts as a switch between the battery and solar panel. The battery is charged with constant 3-stage charging, i.e., bulk, float and absorb. Pulse width modulation or PWM is the technique to modulate the pulse width to change the voltage and frequency of energy from solar panel to charge the battery. One of the greatest pros of PWM controllers is that it helps to prevent overcharging while charging the battery. As for the cost, PWM controllers are less expensive compared to MPPT controllers. MPPT (maximum power point) controller offers an indirect connection between the battery and the solar panel. The DC/DC converter takes extra photovoltaic voltage and transforms this into additional current at lower voltage. MPPT controllers adjust the voltage to maintain the most efficient level of power. In cooler conditions, MPPT controllers are observed to be more effective than PWM controllers due to their ability to capture extra PV voltage. Solar panels used in All In One solar street lights Though both monocrystalline and polycrystalline solar panels are used in solar street lights, polycrystalline solar panels are most commonly used in All In One solar street lights due to their cost effectiveness. Since most of the All In One solar street lights use motion sensors, they do not require solar panels with more wattage. Batteries used in All In One solar street lights Lithium ion phosphate (LiFePO4) batteries are widely used in All In One solar street lights due to their multiple advantages. LiFePO4 batteries offer upper and lower voltage protection and longer lifespan. These batteries can operate in different temperature range and are maintenance free. LiFePo4 batteries are the perfect choice for All In One solar street lights due to their relatively small and light feature. Lithium-ion as well as lead acid batteries are also used in some All In One solar street lights. Light source used in All In One solar street light LED light source is used in as it consumes less energy and gives higher luminosity. Installation of All In One solar street lights Compared to integrated solar street lights, the installation of All In One solar street lights can be carried out easily. The All In One solar street light can be effortlessly mounted due to its compact size and also due to the fact that there are no wires or cables to connect. They can be installed either on a pole or on a wall. The pole should be fixed to a flat ground without inclination. The light fixture should be installed to the pole before erecting the pole. The pole should go at least 3 feet deep inside the ground. The basic cage must be secured to the ground using concrete. It is essential to place the poles at even widths to provide uniform brightness to the entire area. The poles must be placed in the right position and angle so that the panels get sufficient direct sunlight throughout the day. Since All In One solar street lights have dusk to dawn feature, they need very minimal maintenance once installed. Rain water washes away most of the dust and dirt off the solar panels; however, routine cleaning of the panels helps the efficiency of All In One solar street lights. The solar panels can be cleaned by wiping them with a soft cloth or spraying water with a jet spray. Occasionally, you may inspect the installation bracket and the mounting arm to look for any damage. The All In One solar street lights are automatic in its function. They are operated with infrared motion sensor which helps to detect movement in its field and illuminate the lights, thereby ensuring security. Also, the controller can be set to operate in a timer-based manner where in the lights operate in full brightness for the first four hours and then later, in lower light for rest of the time. With the motion sensor and dimming options, the All In One solar street lights tend to save energy, thereby guaranteeing longer life to the lighting fixture. No cable work or electric equipment is needed, so the installation/construction cost is lesser. No need of manual intervention after installation, so the management cost is lesser. The lights are powered solely by using solar energy and no conventional energy is used, so the operation cost is lesser. Installation is easier and faster and maintenance is very minimal. Compared to integrated solar street lights, All In One street lights are less expensive. Since All In One solar street light requires direct sunlight to give its full potential at night, it may not be able to meet requirement of the areas with insufficient sunlight. Since having shadows may obstruct the sunlight to fall onto the solar panels to charge them efficiently, installation sites may be limited. Initial investment to purchase All In One solar street light is high compared to traditional lighting system. However, the benefit of advantages is far beyond the shortcomings of disadvantages. With the technological advancement, All In One solar street lights will be more and more used in the coming future.3.

Grid-tied inverters work by taking Direct current from your solar panels and converting it to alternating current which is then fed into the state grid even as you use it in various appliances. This means that the balance of your power output is used in the grid. When your power goes off you can get power from your balance. It works just like a bank where the utility company measures and tracks your power input into the grid to ensure they have data of your power input into the grid. This means that whenever you have extra power produced from your solar system, it will flow into the grid system and be credited to your power account from which you can take when your solar power goes off. On the other side, an off-grid inverter needs to operate together with a battery. Here, as the solar panels produce direct current they feed it to the charge controller. From here the direct current is channeled to the batteries for storage, from the batteries the direct current is then fed to the inverter which then converts the direct current to alternating current for use in powering your appliances. The difference, therefore, is that while grid-tied solar inverters convert direct current from the solar panels to alternating current, the off-grid inverters convert direct current from battery banks to alternating current. There is a need to always consider the choice of your solar panel. It will affect the quality and the amount of energy output from the whole system. Solar panels convert sunlight into DC (direct current) power; while an inverter converts the direct current into AC (alternating current) power, that is then used to powering homes and electric appliances. The different types of solar inverters are highlighted below; These are the most pocket-friendly inverters. They are a good choice if all your panels are exposed to a lot of sunlight or if they all face the same direction. Each row of panels is called a string, and that string is attached to an inverter. If a panel on the string does not receive enough light, then it will drag the performance of all the others down to its level. Power optimizers are a solution to any performance defects caused by a poorly performing solar panel. One is installed on each panel and conditions the DC current before it reaches the inverter. They are a good compromise between standard string inverters and more expensive microinverters. These are installed on each panel and they convert the DC power into AC power right at the panel. They are more efficient than string inverters because a single panel will not affect the performance of any other panels. They are a good solution for homes where one or more of the panels are in the shade. They are expensive, so they should only be purchased if necessary. Central inverters are similar to string inverters but they are much larger and can support more strings of panels. Instead of strings running directly to the inverter, as with string models, the strings are connected together in a common combiner box that runs the DC power to the central inverter where it is converted to AC power. Central inverters require fewer component connections but require a pad and combiner box. They are best suited for large installations with consistent production across the array. With the growth of solar and storage, battery-based inverter/chargers are becoming increasingly important. Battery based inverter/chargers are bi-directional in nature, including both a battery charger and an inverter. They require a battery to operate. Battery-based inverter/chargers may be grid-interactive, standalone grid-tied or off-grid, depending on their UL rating and design. The major benefit of inverter/chargers is that they provide for continuous operation of critical loads irrespective of the presence or condition of the grid.

The economic development has made our city construction work more emboldened, and more advanced equipment can be used.Solar street light with sensor have entered our line of view in this context. It has been widely used in many large cities in China. As an energy-saving product that can effectively save energy and protect the environment, we want to make solar street light with sensor better for us,extend its life services.In actual use, also need to pay more attention to these issues.The first is the heat dissipation problem. We all know that solar street light with sensor are generally led light source, so its service life is very long and if you want to improve its service life for a longer time, it is necessary to increase the heat dissipation and constant current of the led lamp.Work harder,effective heat dissipation can help control the temperature of the led tube.The second is the anti-theft problem.Because solar street light with sensor need to be equipped with solar cells and solar panels,this has become the target of theft of criminals. Therefore, in order to be able to use normally, it will not affect the night lighting. During construction, it is necessary to pay attention to effective anti-theft, and the battery can be buried. Under the pedestal of the solar street light with sensor,the cement is poured on it, so that the solar battery can be effectively prevented from being stolen, the economic loss is reduced,and the normal lighting work is not affected. In addition,solar street light with sensor can use lithium battery,the lithium battery has one-third of the weight of the same-power lead-acid gel battery and one-third of the volume. It is even more difficult to be stolen by installing it inside a pole, inside a bracket.The third is to choose the right solar street light with sensor controller. Although the controller is very inconspicuous in the entire solar street light with sensor system, its quality will directly affect the life of the entire street lamp system and the cost of use, so be sure to choose a controller with excellent quality during construction.As a typical example of green lighting equipment, the use of solar street light with sensor is very beneficial to our country and the masses. If you want to fully utilize its long-life advantages, you must add more in construction and pay attention in actual use.Optical sensors or magnetic sensors for position control?Optical sensors can be very precise, but they will also be pricey maybe ($75-300) Magnetic sensors can be are accurate as far as on/ off, they are also going to be much cheaper ($20-50) Both types of sensors can be tampered with if that is something you are worrying about but the optical will be harder to tamper the single.2001elantra,loss of power,especially on up grades.?you have replaced a few items that would do this. however we need a diagnostic check to see fault codes. using these we can have a better chance of a solution. for example coil pack, plugs,crank sensor wo not do that. map sensor and TP sensor may.. do that. as its sudden cut back and reapplication of power we need to look at ecu inputs. this would seem to be an electrical issue such as loose wire on a connector. accelerating gently up and down by itself is more of an actuator issue. again diagnostic check with a competent technician is best way to get decent fix.Bad oxygen sensor? or catalytic converter?a low catalyst efficiency very rarely points to a failing cat or o2 sensor. the fact that it does not get hot enough to work right can be the issue. look for a vacuum leak on that bank or an exhaust leak on that side. either one could lead to that.Serial sensors and the YunI do not have any experience with the Yun so I can not comment on that specifically, but the only problem you will encounter with using SoftwareSerial is that you can only communicate with one device at a time.This means you will have to make a call to listen()before communicating with sensor1. Then when you want to communicate with another sensor, you have to do the same.

Hybrid batteries are typically warranted for 8 or 10 years, not 2 or 3. And that's a full replacement warranty, not pro-rated. Also Lithium batteries are not used in hybrids yet, today's cars use NiMH (Nickel Metal Hydride), which is fully recyclable and not a big issue for mining either. Edit: Your "Additional Details" have added another inaccurate assumption. The electronics in a hybrid vehicle do not allow the batteries to go through a full charge-discharge cycle, as that severely shortens the life of a battery. Instead, the batteries are kept within a relatively narrow range of state of charge; typically around 50% to 85%. That extends the lifetime dramatically. How else do you explain 8 or 10 year warranties on the batteries? Car companies are not in the business of giving away expensive parts under warranty.Top 11 Lithium and Battery Stocks to Buy NowThe company reported during their September 2020 quarterly report a signed binding agreement with Tesla, Inc. for the supply of Spodumene concentrate from Piedmont's North Carolina deposit to Tesla.

Think heat, gassing, or both.2 If the battery uses up the chemicals in the initial chemical reaction, there is nothing to push back. Therefore attempts to charge the battery will just produce heat, or explosive gases, or both.3 If the battery emits noctious fumes under a recharge, we say it isn't rechargeable. For both your sake and the environment, these batteries should be charged in a sealed environment.Think Fire, Exploding Batteries, Noctious Fumes Etc.

Good luckRRHow to Extinguish Lithium Battery FiresWhile batteries in common use are generally safe, the question does arise about what happens when they catch fire. This may be because of thermal runaway or physical trauma. Any fire can run out of control; foreknowledge is therefore essential. Especially if you need to extinguish lithium battery fires, and water seems the obvious solution. We posted a high school experiment further on in this post. We did so because, although this does not appear dangerous we wanted to point out the research assistant wears protective clothing and is not working alone. This experiment shows that broken lithium batteries are considerably more toxic in the presence of water than other similar-size cells. Hence, we should avoid attempting to extinguish lithium battery fires with water. The primary reason is lithium burns in the air we breathe. And moreover reacts with water to form explosive hydrogen that may develop a chain reaction. Water is clearly not a lithium battery's friend. It may ignite during thermal runaway, or in the presence of an adjacent fire. When a lithium battery overheats for whatever reason, it expands rapidly causing short-circuits inside. This may spontaneously release energy that can ignite adjacent cells when it explodes. Emergency personnel must wear protective clothing, especially eye-protection, respirator, and rubber gloves. Extinguishing a lithium battery fire is not something you or we should attempt. We provide this information in good faith along the lines we understand. Never attempt to extinguish lithium battery fires yourself. Your health and safety are far more important. Please call the emergency services instead as these are Class D fires.12V 55AH Lithium Battery Replacement for Motor Guide VariMax TrollingInvest in power with the Mighty Max 12V 55ah Lithium Iron Phosphate Battery.

NEW DELHI: The President of India, Pranab Mukherjee inaugurated the 44 Kms Deoghar - Basukinath Solar Street Light Project. Speaking on the occasion, the President said that the problem of job creation cannot be solved unless people are imparted skills to increase their employability. India has a huge workforce and skill development can help in economic development of this vast country. The President said that he believes that initiatives launched such as Deoghar - Basukinath Solar Street Light Project; Software Technology Parks of India Centre; Employees State Insurance Corporation Hospital and Driver's Training Centres will transform the employment landscape of this region. The President said that Jharkhand played a key role in India's freedom struggle. The pain and sacrifices of Sidho Murmu, Kanho Murmu, Tilka Manjhi and Birsa Munda are always remembered. The state has made progress on many fronts since attaining statehood in 2000. Its rich deposits of mineral resources, forests and industrial infrastructure etc. have laid down the foundation for all-round development. The President said that he comes from Bengal. Indeed, Jharkhand, Bihar, undivided Bengal, Orissa and Assam were part of the same Bengal Presidency for a long period in the earlier part of the last century. The area has a shared past and heritage and its shaping in the post Independence era has also been similar.

Street lighting is one of the largest single expenditure for many cities around the world. Staying up-to-date with new developments and adopting solar lighting technologies dramatically reduces electricity costs and green house emissions.Solar street lighting can be an economically viable option in many applications. Not only in areas where the cost of providing electricity is too expensive, but also in situations where reducing running costs is a priority. Solar street lights are a judicious choice for parking lots, parks, highways, roads airports, area lighting and many other public, private and military sites.When installing solar street lights, there is no need for excavation to put cables, as power does not depend of the grid. Solar energy is used to charge the self-contained battery during daylight and at night, the power released by the battery powers the lights. A timer or a photocell controls the operation of the lights from dusk to dawn. Set up is quick, usually less than a day per solar street light. It can be done by any experienced technician. The solar panel needs to be properly aligned to gather maximum energy during the day.There are few things to consider when planning using solar street lights: It is very important to correctly size the different components (solar panels,lamp, battery, solar controller) according to the geographic area. Well designed solar street lights systems can provide adequate and low cost illumination for years, with minimum maintenance. LED (Light Emitting Diodes) lamps can work up to 50.000 hours.

Is electricity understood well enough in Eberron to produce current and simple electrical devices?You are operating under a misconception: lightning and electricity in Eberron (and most D&D worlds) does not work like it does in reality. This is to some degree just simplification; it would not be fun to have to pull out Maxwell's equations every time an electrical attack happened. But this simplification does have some rather important side-effects.A prime example of this would be a character in full plate mail getting struck by lightning. In the real world, the fellow struck by lightning is completely protected thanks to his Faraday-cage / full plate armor. In D&D, the character is damaged (barring electrical resistances, immunities and other such effects). Another example is the lightning bolt spell itself. In 5e, for example, the spell produces a bolt of lightning five-feet across and 100-ft long. In the real world, if we produced enough voltage to cross a 100-ft long span of air, the bolt would ground itself out because the path of least resistance will be the 5-foot span directly downward. There are reasons stun batons have to basically make skin contact, and tasers have wires to direct the flow of electricity. Since electricity demonstrably behaves differently in Eberron than in reality, you should not expect electrical engineering solutions to work in Eberron either.This doesn't mean there aren't solutions in Eberron that would work even when hit by Dispel Magic, however. We had lanterns and torches long before we harnessed electricity, and cannon wicks have been around since the invention of the cannon------What are some of the startups in the field of smart energy and smart streetlighting in India?Photron Power- All-in-One Solar LED Street Lights Manufactures in India.Photron being a well known Solar LED Solar manufacture & Supplier in India is among the few LED street light manufactures in India.

By way of analogy, the path of a solar eclipse will cross the United States this summer. People are already being warned not to look directly at the Sun during the eclipse without protection. The reason of course is that looking at a partially eclipsed Sun may cause permanent damage to ones eyes. Most of that damage results from from the Sun's infrared rather than visible output. Just because one cannot see that infrared radiation does not mean it won't hurt you.The same applies to radio antenna. While radio antenna are typically designed to be insensitive to visible and infrared, an unprotected radio antenna, like an unprotected eye, will suffer irreparable damage when pointed at the Sun.What about a radio antenna protected by a radome? Those can be and are pointed directly at the Sun. What they see is a large body that radiates at an effective temperature well above the 5778 K of the surface of the Sun. The Sun's chromosphere can have an effective blackbody temperature in the microwave and radio frequencies in the tens of thousands of kelvins, and the solar corona, in the millions of kelvins.This is particularly the case when the Sun is active, a one to four year long period during the Sun's eleven year solar cycle. Solar scientists aim radome-protected radio antenna directly at the Sun because the deviations from blackbody radiation at 10.7 centimeters are highly correlated with deviations at short wavelengths. Scientists use the Sun's radiation at 10.7 cm as a bellwether of the Sun's activity.Suppose someone decides to ping the Sun with a radio antenna inside a radome while the Sun is quiet. Even during quiet periods, the Sun still outputs radiation in the microwave and radio frequencies with an effective temperature of nearly 10000 kelvins. The large output from the Sun in the microwave and radio frequencies will overwhelm that little ping, even when the Sun is at its quietest.Once again by way of analogy, think of pointing a flashlight directly at a street light. Flashlights work great when pointed at a somewhat nearby dark patch of ground. They don't do much at all when pointed at a more remote source of light

BHUBANESWAR: The solar street lighting project in Bhubaneswar is likely to be delayed further as the Bhubaneswar Municipal Corporation (BMC) on Tuesday expressed its inability to allot land to the Orissa Renewable Energy Development Agency (Oreda) at the proposed site near Unit-8 Boys' High School for setting up a solar photovoltaic (SPV) power plant. The BMC, instead, has requested the director of estates to allot land near Orissa University of Agriculture and Technology (OUAT). Solar lighting will be installed on the stretch between OUAT and Delta square for which Oreda had sought land from BMC. "Since BMC is the user of solar lights, it has to provide us land to set up the plant which will facilitate the lighting," said deputy director, Oreda, B K Swain. He said they had sought 600 sq metre land for installing solar panel and batteries. A BMC official said they had no piece of land at the proposed place. "We are hopeful that Oreda will be provided land soon," said the official. OREDA is the nodal agency for technical assistance for solar lighting and BMC would provide the required support. The solar lights on the proposed stretch would cost about Rs 1.14 crore. The Union ministry of new and renewable energy (MNRE) will give 30% of the project cost, sources said. The BMC in 2011 was included in the MNRE's 'solar city' project, which will turn 60 cities across the country into solar cities. "The solar powered streetlight was planned by BMC. It is supported by the science and technology department and Oreda," BMC commissioner Sanjib Mishra said. At present, the BMC spends around Rs 5 crore on street lighting annually. Solar lights are expected to cut down on the expenses significantly. Earlier, the civic body had launched environment-friendly LED street lighting system in some parts of the city to cut down on energy expenses. BMC aims to convert at least 10% street lights into solar powered lights by 2020.
