Incandescent light wavelength range
WebDec 20, 2009 · 963. 0. Well if the light is coming from a point source in all directions equally--at any distance r there is a ball of light with surface area 4 pi r ^2. The sum of all of the light is 100 watts but only a portion of the sphere strikes the solar cell. Then from a purely proportionate view. 100w/4 pi r^2 = x watts/ area of panel.
