How much energy does solar energy produce?

Question

PLZ PLZ HELP!!!!!!!!!!!

Answer 1

By solar energy, I assume you are not referring to the general term for all the energy transmitted by the sun, including light, heat and cosmic and electromagnetic raditation.  I do not have exact figures, but it is obviously enuogh to sustain life on earth and to control the climate.

As for solar energy devices, all I can really say is that they have domestic uses in certain climates, depending in part on how the rays of the sun hit the solar battery device.  They are still used mainly for smaller devices, such as electronic calculators.  They are used as well in outer space, where recharging batteries through more commonly-used means is not feasible.

As far as quantity is concerned, I can give you this much general information, which is not too technical or overwhelming, from Wikipedia:

The power output of a solar array is measured in watts or kilowatts. In order to calculate the typical energy needs of the application, a measurement in watt-hours, kilowatt-hours or kilowatt-hours per day is often used. A common rule of thumb is that average power is equal to 20% of peak power, so that each peak kilowatt of solar array output power corresponds to energy production of 4.8 kWh per day.

Answer 2

Your question is kinda vague but here is one figure where the Sun hits the Earth's atmosphere.

The amount of solar radiation received at the outer surface of Earth's atmosphere varied little from an average value of 1,366 watts per square meter (W/m²).

Answer 3

depends where you are. you can find your local solar potential on an insolation map eg;

the limit to your size of array will be price or area, so take the number of panels you can afford or have room for, and multiply their combined stated peak power rate by the sun hours from the insolation map.

another complication, tracking panels will catch more sun than stationary ones, and the optimum angle for a fixed panel will depend on your lattitude.

Answer 4

About 75 Watts per square foot.
