Effective Intensity = 0.12 * 250W/m^2 =
30W/m^2.
Area=(1200W * 1m^2/30W) = 40 m^2.
a solar panel is 12% efficient at converting sunlight into electrical energy.on average the sunlight that strikes the earth's surface has an intensity of 250 w/m^2 which of the following is the best estimate for the area of the solar panel needed to provide 1.2Kw of energy to a home?
