Production description

A solar panel is a collection of solar cells. Lots of small solar cells spread over a large area can work together to provide enough power to be useful. The more light that hits a cell, the more electricity it produces, so spacecraft are usually designed with solar panels that can always be pointed at the Sun even as the rest of the body of the spacecraft moves around, much as a tank turret can be aimed independently of where the tank is going.

A photovoltaic (in short PV) module is a packaged, connected assembly of typically 6×10 solar cells. Solar Photovoltaic panels constitute the solar array of a photovoltaic system that generates and supplies solar electricityin commercial and residential applications. Each module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 365 watts. 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:How can you get affordable Solar Panels?

Q:how much watts can a x2 inch solar panel make?
A solar cell's purpose is to generate electricity through the release of electrons from a material that is bombarded by electromagnetic radiation or photons. Most crystalline solar cells are sensitive to visible radiation from 400 - 700 nanometers, which correspond to 3. - .8 electron volts, of the visible region as shown by ACEPT W3 Group (999) and also into the near infrared spectrum. As the wavelength of the electromagnetic radiation increases, the amount of electron volts decreases. This means that infrared radiation has less electron volts than the visible spectrum of light (because it has a larger wavelength than visible light) and ultraviolet and gamma radiation has more electron volts than both the visible spectrum of light and infrared radiation (because they have a smaller wavelength than both infrared and visible light). Abramowitz, M., Davidson, M., Neaves, S. (2003) wrote that all forms of electromagnetic radiation originate from the atom which contain orbiting electrons around its nucleus. When those electrons absorb more external energy than they can contain in order to be stable, the extra energy is released in the form of an electromagnetic wave. That electromagnetic wave contains a magnetic field and an electric field, one offset by ninety degrees to the other along the propagation plane.
Q:Solar Panels: How long will it be before solar panels are cheap & effecient enough so that everyone?
As the cost of fossil fuels continues to rise, solar panels become of more value. At one time they were looked on as a rather expensive investment with only a long-term pay off. Now oil is so expensive other sources of power such as wind, solar panels and geothermal energy become relatively cheaper. The efficiency of solar panels is expected to rise so that even in regions where sunlight is limited, these become a realistic investment.
Q:Help with solar panels?
It's depends on how many electrical appliances at home. For small house average need 800-200 watts electricity. The average solar panel kits produce 75-50 watts depending on the size of the panel. You needs minimum 5 solar panels.

Q:Powering my house with solar panels?
I had a survey of my home and it was estimated at $30K with a 30% rebate from the government. It would take about 5 years to pay back the cost. I elected to go solar water heating instead. 2 panels with piping installed to an 80 gallon electric water heater with an internal heat exchanger. One small photo voltaic panel to run the pump. There is ethylene glycol inside the pipe and it circulates and heats the water. Works excellent. I live in Nor-Cal and we get a lot of sun. I need to comment on another statement that photo voltaic cells cost more energy to produce they generate. Maybe once but not true any longer. {Solar cells and energy payback In the 990s, when silicon cells were twice as thick, efficiencies 30% lower than today and lifetimes shorter, it may well have cost more energy to make a cell than it could generate in a lifetime. The energy payback time of a modern photovoltaic module is anywhere from to 20 years (usually under five)[9] depending on the type and where it is used (see net energy gain). This means solar cells can be net energy producers, meaning they generate more energy over their lifetime than the energy expended in producing them}
Q:I need help with solar panels?
Even if you can buy solar glass, you CAN'T properly repair the panel for the cost of having a professional do the work.
Q:I would like some info on Solar panels and Wind Generators...please?
You may have to put a snow roof over the wind generator to keep it working. A solar hot water system might be hard investment where you are but it could work if it's designed right. Check out the solar companies in your area for ideas.
Q:Solar panels for a netbook?
That strikes me as completely impractical for most circumstances. The power output of your mains adapter is 30W and to do that you are looking at at least five or six square feet of solar panels costing in the region of $600 even from a surplus supplier I know. You could do it cheaper (maybe $50 on panels) but then you would be looking a more primitive panels and need perhaps thirty square feet of solar panels. This is a completely different exercise to creating a solar powered USB charger - the power requirement is a lot higher. Astronomy and space?
Q:how to make your own solar panel?
There are several types of solar panels. If you mean photovoltaic panels for generating electricity, that is a really advanced project that few amateurs are equipped to do. In the long run, it will be a lot cheaper and easier to buy factory made PV panels. You can try building one by sandwiching an array of photovoltaic cells between a sheet of glass or plexiglass and a sheet of aluminum. Remember that this assembly must be able to withstand great heat, and it must be sealed to make absolutely sure it does not leak.
