Q:I have a 20 watt solar panel that I want to set up. I need to connect it to the solar controller but do not know what cable to use. I plan on adding more solar panels down the line. What would be the best cable to use?

on the controller, it writes which would be related with image voltaic panel which would be related with battery which would be related with load all of it write on the image voltaic controller. only see the controller

Q:I have a playstation PSP charger that is 5v 2A, so it takes 0 watts.I have several small solar panels that put out watt a piece and are 4 volts, 250mAhow can I get my 0 watts to be 5v 2A instead of 4v 250mA? the voltages have to match up right?also, what's a 3-T regulator that controls voltage?

The first item is whether the psp charger output is ac or dc. IF, AC then you are stuck as the panels put out DC. (Increasing the voltage enough to cover invertor losses is not practical in this instance!) IF DC, then you need to combine panels to produce 2 Amps, after which it is run through the 3 terminal VOLTAGE regulator to limit the voltage to 5v. That is 8 panels in parallel in 2 groups placed in series = 2amps at 8 volts, then add regulator for 2 amps at 5v. (Parallel increases amps, series increases volts.) Total panels required is 6 panels.

Q:what kind of rays are used in solar panels?

Ultra Violet rays from the sun.

Q:How do solar panels perform in extreme temperatures?

Solar panels can still generate electricity in extreme temperatures, but their efficiency may be slightly affected. In high temperatures, solar panels may experience a decrease in their power output due to increased resistance in the electrical circuits. In extremely cold temperatures, solar panels may become less efficient temporarily, but they can still produce electricity as long as there is sunlight. Overall, while extreme temperatures can have a minor impact on solar panel performance, they are designed to withstand a wide range of weather conditions and continue to produce clean energy.

Q:Do solar panels require batteries?

No, solar panels do not require batteries. They generate electricity directly from sunlight and can be connected to the electrical grid to supply power or utilize net metering to offset energy consumption. However, batteries can be used to store excess energy for later use when solar generation is low or during power outages.

Q:If a solar panel is a .5kW system, what length of time is it putting out that much power? Every hour?

Power = work done/time taken In other words, Watts=Joules/second. In this respect, power is a little like speed (m/s). Your question is looking at a car with a 50mph top speed, and asking how long is it going that fast? The solar panel will produce .5KW for as long as you require it. Enough to boil a kettle, run a modest electric heater etc,

Q:who has solar panels on their home and are they worth it

There are different kinds of solar panels. The biggest division is between photovoltaic panels that produce electricity and thermal solar panels that produce heat for hot water and space heating. Commercial photovoltaic panels are from 8 to 24% efficient while solar thermal panels are from 60 to 80% efficient. Solar thermal panels especially for hot water have a much higher ROI (return on investment) than photovoltaic panels. A solar hot water system may have a payback period (when savings equal the investment) as short as 3 to 5 years while photovoltaic panels will typically have a payback period between 7 and 5 years. Solar panels especially in times of low interest rates may be a very worthwhile investment with a better return than you can find almost anywhere else. But they are also highly dependent upon your situation. Owning a home with a good southern exposure is a prerequisite.

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?

If you are in the desert and near the equator you will need fewer panels than if you live in a rain forest or Alaska. If you live in a wind tunnel with consistent strong wind, you will have better results than if you live where there often is a lull in the wind and changes of direction of the wind. If you already pump your water by hand, generate your own electricity by cycling using your legs, and go to bed whenever it gets dark out, you might make it. But if you tend to cook and launder on the grid, run a refrigerator, perhaps heat your house or air condition it, own various gadgets you plug into outlets to use, like lamps, puters, toaster, shaver, blender, dishwasher etc, you may not be able to get off the grid.

Q:Can solar panels be installed on schools or universities?

Yes, solar panels can definitely be installed on schools or universities. In fact, many educational institutions are increasingly adopting solar energy as a sustainable and cost-effective solution to meet their electricity needs. By installing solar panels, schools and universities can reduce their carbon footprint, save money on energy bills, and provide a valuable educational opportunity for students to learn about renewable energy.

Q:For a computer technology project we are using solar panels and trying to see different methods that will increase the output of solar power from these panels. For now, we have got polymer stickers and mirrors. Are there any more methods, or information that increase the solar power? Please and thank you :)

If it's a solar heating panel, add insulation around it. If it's a solar electric panel, chill it in some manner, like with a fan, mist of water, etc. Electric panels are generally more efficient when cold.
