The solar panels on the roof of a house measure 4.0 m by 5.2 m. Assume they convert 12% of the incident EM wave's energy to electrical energy.

(a) 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) 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 62.0° from the normal?

____kW
