Product description
A solar cell, or photovoltaic cell (in very early days also termed "solar battery"[1] – a denotation which nowadays has a totally different meaning, see here), is an electrical device that converts the energy of lightdirectly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon.[2] It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. Solar cells are the building blocks of photovoltaic modules, otherwise known as solar panels.
The efficiency of a module determines the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16% efficient 230 watt module. There are a few solar panels available that are exceeding 19% efficiency. A single solar module can produce only a limited amount of power; most installations contain multiple modules. A photovoltaic system typically includes a panel or an array of solar modules, a solar inverter, and sometimes a battery and/or solar tracker and interconnection wiring.

- Q: Hello Yahoo, I am doing another one of my wacky inventions however I need something that will give me 2V of power!I don't want to connect loads of AA batteries into a battery holder as this shall run out quickly and become expensive in the long run, I don't want to carry around a big car battery either.I have been searching around on OKorder .uk and found some Solar-Powered 2V Trickle Chargers. These say they shall work on cloudy days (which is perfect as the majority of the time that is all we get!) but could I use it as an independent power source?If I attached the thing I want to run to the solar panel will it supply it with 2V of power?
- If you want to run something from a solar panel, you should remember that the power from the panel is only available when there is reasonable sunshine on the panel. Usually the solar panels are used with solar regulators in order to charge batteries. These batteries are used as energy storage for when the sun is not shining. Now, this does not mean that you cannot drive instruments directly from the solar panel and regulator. To do this, you will need a panel that has sufficient power to drive your instrument. An example is the solar powered garden or fountain pumps. I have driven 2V computer fans directly from the small solar panels - useful for cooling of things such as pool pump housings. The solar regulator is used to convert the solar panel output to a 3.5V output in order to charge lead acid batteries. I have used MPPT regulators (maximum power point tracking) which is more efficient than the standard solar regulator. If you don't use these regulators you may find the solar panel producing up to 7-9V in good sunshine which is not good for your instruments that are expecting 2-3V. Hence the answer to your question is that you will need to have a battery being charged to get useful power from the solar panels via a solar regulator.
- Q: Rooftop solar panel (not sure if rubber or plastic?) has leak arising from thin vertical crack in panel about long. Any ideas for repair?Thanks.

- Q: What are solar panels?
- Solar panel is a generic term used to describe a device that collects and converts solar energy into electricity or heat. Photovoltaic module, used to generate electricity Solar thermal collector, used to generate heat Solar hot water panel, used to heat water, often in homes but i guess u mean the ones which generete electricity a photovoltaic module is a packaged interconnected assembly of photovoltaic cells, also known as solar cells. An installation of photovoltaic modules or panels is known as a photovoltaic array. Photovoltaic cells typically require protection from the environment. For cost and practicality reasons a number of cells are connected electrically and packaged in a photovoltaic module, while a collection of these modules that are mechanically fastened together, wired, and designed to be a field-installable unit are known as a photovoltaic panel or simply solar panel. A photovoltaic installation typically includes an array of photovoltaic modules or panels, an inverter, batteries (for off grid) and interconnected wiring.
- Q: How do solar panels affect the electrical grid?
- Solar panels affect the electrical grid by supplying clean and renewable energy. When solar panels generate excess electricity, it can be fed back into the grid, reducing the overall demand for fossil fuel-based power generation. This helps to stabilize the grid and reduce carbon emissions. However, the intermittent nature of solar power can create challenges for grid operators in managing variations in supply and demand.
- Q: is a wind turbine better than solar panels
- Both solar and wind production is largely a function of location. If you live in the southwest where the sun shines most days, maybe solar is an option. If you happen to live in one of the wind corridors, maybe wind is an option. Neither one will be as reliable and cheap as your grid power, though. Best is to concentrate on conservation of energy use.
- Q: Can solar panels be used in areas with high pollution levels?
- Yes, solar panels can be used in areas with high pollution levels. While pollution can potentially decrease the efficiency of solar panels, they can still generate electricity even in polluted environments. Additionally, using solar energy can help in reducing reliance on polluting fossil fuels, contributing to the overall improvement of air quality.
- Q: my solar car works when using the Battery but when there is sunlight i connect the wires to the solar panel and it does not work...................HELP
- leave the car in the sun for a few hours to see if it charges. if not, the panel is defective. get it replaced b4 the science fair
- Q: Can solar panels be installed on water bodies or reservoirs?
- Yes, solar panels can be installed on water bodies or reservoirs. This is known as floating solar or floating photovoltaic (FPV) technology. It involves mounting solar panels on buoyant platforms on the surface of the water. This approach offers several benefits, including reduced land requirements, increased energy generation due to the cooling effect of water, and reduced evaporation from the water body.
- Q: Can solar panels be installed on a military base or facility?
- Yes, solar panels can be installed on a military base or facility. In fact, many military bases have already implemented solar energy systems as part of their efforts to reduce reliance on traditional energy sources and promote sustainability. Solar panels can provide a reliable and cost-effective source of renewable energy to power various operations and facilities on military bases.
- 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?
- I live in the Southwest where the sun shines almost every day. I got a quote for Solar system to produce about enough to cover my annual usage. My annual average electrical usage costs about $2300, or about $90/MO. The system costs around $30,000 but I can get rebates and some of your tax dollars in subsidies to bring my cost down to under $20,000. I can borrow $20,000 for 3 years at 7% and pay $95/MO, so in 3 years I will have the system paid for. As you can see, I don't start Saving any money for a long time. Maybe the rates will go up in later years which will help, but My friends that have solar systems tell me things like controllers go bad over time and they cost like $3000. Will it ever pay for itself? Maybe. Please note. This still does not get me off the grid. This system will not support things like an electric stove, air conditioning, Pool pump running, etc. so I still need the grid for when these operate and my usage peaks. If I installed a system that would totally support everything 24/7 the cost would be astronomical. If you live in the east, midwest, or NW where you have cloudy days, your economic calculations will be much less favorable I would think, unless your power costs are much higher than mine..
