Chapter 10, Problem 30E
Textbook Problem

If a typical home requires an average power of 1 kW, calculate how many square meters of PV cells would be required to supply that power. Assume that solar power is 1 .0 × 10 3 W/m2 and that the cells are 15% efficient in converting sunlight to electrical energy. Could such an array meet the peak power demands? Could such an array fit on a rooftop?
