Question

which radiation should i consider for calculating solar power

Answer 1

Answer:

Solar radiation with wavelengths of 380 nm to 750 nm (violet to red) strike the material with enough energy to knock electrons from their weak bonds and create an electric current. The unused wavelengths (ultraviolet & infrared) do not have enough energy to dislodge the electrons and are absorbed as heat.

here's ur answer mate

Answer 2

Divide the maximum wattage on your panel by this number, then multiply it by 100 percent you'll get an efficiency rating. For instance, if 1,000 watts per square meter of sunlight hits your home (the amount of sunlight assumed during STC testing) and your panel is 2 square meters, you'll end up with 2,000
