The solar panels on the roof of a house measure 4.0 meter by 6.7 meter. Suppose they convert 12 percent of the incident EM wave's energy to electrical energy.
(a) Find what average power do the panels supply when the incident intensity is 1.0 kW/m2 and the panels are perpendicular to the incident light?
kW
(b) Find what average power do the panels supply when the incident intensity is 0.80 kW/m2 and the light is incident at an angle of 56 degree from the normal?
kW
