Product Description

sunpower flexible solar panel 20w for sale
Flexible solar panel are designed to provide a powerful charging solution for batteries and conform to almost any surface. Unlike other 'flexible' products, these use high-efficiency monocrystalline cells that produce more power per square foot than any other flexible panel on the market.
   An impermeable lamination coats the entire module, allowing it to contour and flex against curved areas, eliminating any need for custom mounts.
   The panel can be affixed by adhesive or screw mounting options and grommets are an added bonus for ease-of-installation. The thin, lightweight module can also be sewn into canvas, making it a truly versatile solar m odule.
     The Solar Flex panels are aerodynamic and DURABLE - a virtually unbreakable solar battery charger for RVs, boats and long-haul trucks.

Q: I have several 6v 4.5a sealed lead acid batteries. I would like to hook one of them up to a solar panel and have it stay charged from the solar panel all the time, but not overcharged. Is there a simple way to do this with an IC or something? I am only a beginner with circuits so I want it to be something very easy to make. Basically, I want it to stay charged all the time so it's available if I need it for a power out or something.Thanks.: Yes, you can purchase a solar photovoltaic array to keep your batteries charged. You will need a Photovoltaic Cell Panel that produces 27 + watts (6volts x 4.5 amps = 27 watts) at 6 volts of electricity, a Charge Controller that allows only 4.5 amps of power through to the battery and will reduce the amps as the battery nears full charge and shut off the Panel when the battery is fully charged, and a 6v. Battery. Figure you will need a photovoltaic panel capable of producing a minimum of 27 watts if you are going to charge a completely dead 6 v. battery in one day. (with a clear sky). The way the system works is the sunlight strikes the cells on the panel and releases the excess electrons in the cells, they travel along central wires to your battery and charge the battery. When the sun sets, the procedure is reversed and the electrons flow backwards from the battery, into the photovoltaic cells. That is where the Charge Controller is needed. It acts a one way gate and lets the electrons go into the battery, but won't let them go backwards to the Panel. Just set your panel in the sun at the optimum angle for the season and your latitude on earth, connect the charge controller and then the battery, and it will keep your battery charged. Don't waste your money on the small wattage solar photovoltaic systems that claim to keep your battery charged. They simply can't do it unless your battery is in like new condition and is fully charged when they are hooked up. If you battery is a few months old, the small wattage photovoltaic systems can't keep up with the loss of power from sulfation inside the battery.

Q: If you need 9400 watts, 75 amps@ 240V, how many solar PV panels do you need?: 75 amps @ 240VDC is 8,000 watts.

Q: How much electricity does a solar panel produce?: The amount of electricity a solar panel produces depends on various factors such as its size, efficiency, location, and weather conditions. On average, a standard-sized solar panel can generate around 250 to 400 watts of electricity per hour under optimal conditions. However, this output can vary significantly throughout the day and across different seasons.

Q: hi so im doing a school project thing and they have a lot of different questions for us that help us decide whether we would rather a city have a nuclear reactor, or solar panel. But i cant seem to get the last 2 questions...help please???so question ........What types of emissions, if any, are produced by each type of generating station? Do these emissions affect human health?question 2.....What are the long term financial costs associated with maintaining each type of generating station?thanks!: You should research nuclear reactors and their emissions. Mostly it's waste heat, and if they use a water-based cooling reactor, there can be significant emissions of water vapor. Some might consider the spent fuel an emission too. Waste nuclear material disposal is a problem. Research it. Solar panels have no emissions during operation, but there is some nasty stuff emitted when they are manufactured. 2: Maintenance of solar panels is pretty straightforward: keep them clean, trim overhanging trees, shrubs, etc., check for and clean corrosion, contaminants, etc. regularly. Maintenance of nuclear power plants, so far, is a full time job for many technicians and engineers. The recently developed portable (the size of a shed) nuclear generators claim zero maintenance for 20+ years. That's a big improvement.

Q: please no dumb answers and list where you got the info.Also how much does it cost to install solar panels for a regular sized house?: Short version is that the sunlight knocks electrons loose from a semiconductor panel, and those loose electrons generate an electrical current. The solar panels have lots of cells arranged in series parallel to get to a higher voltage (usually 2 or 24 volts) and current. This is sent to charge batteries under the control of a charge controller. The voltage from the batteries is sent to an inverter that converts the 2/24 volts to 20/240 VAC for household usage. .

Q: Can solar panels be installed on a streetlight?: Yes, solar panels can be installed on a streetlight. This allows the streetlight to be powered by solar energy, reducing the reliance on traditional electricity sources and making it more sustainable.

Q: quot;Does it take more energy to produce a solar panel than what the same solar panel can generate in its useful lifetime?quot;: No. okorder /... Since then they have only improved. CdTe efficiencies have increased, partly by reducing material use (particularly the depth of the CdS layer)

Q: I have a 2V .5W solar panel and I want to get a battery that can be charged by the solar panel that can then be used to power a 2V .5W fan. Ideally I want all the components to be connected and able to run without interaction. I have very little knowledge in regards to this field which is why I have come to yahoo answers. Any help would be greatly appreciated.: batteries are rated via the CCA, chilly cranking Amps the better the CCa the longer it is going to very last, don,t imagine you want a cost Controller as your continuously drawing juice from it, the picture voltaic panel will keep the bat at its top , then even as the daylight is down , the pump will draw off the bat,

Q: Can solar panels be used in areas with high levels of bird or bat activity?: Yes, solar panels can be used in areas with high levels of bird or bat activity. However, it is important to take certain precautions to minimize the potential risks to birds and bats. These precautions may include using specific panel designs that reduce the chances of bird or bat collisions, implementing bird or bat deterrent measures, and considering the placement of the panels in areas away from known flight paths or nesting sites. By implementing these measures, solar panels can coexist with bird and bat populations while helping to generate clean, renewable energy.

Q: I want to replace my electricity with solar and wind. I live just right outside the city, the roof about 000 square feet. How many windmills/solar panels would it take to get me off the power grid?: Insolation, okorder okorder /... that are 420x420x25 mm so each unit is about .764 m3. If you used these to cover 500 sq ft then you would need (46.45/.764=) 263 of these panels at a cost of ($09.95 x 263=) about $28,953 plus wiring, plus brackets, plus an inverter, plus batteries, plus a battery management system and any labor or your time. Best of luck with it.
