Chapter 10, Problem 10.2YT
Textbook Problem

Square Meters of Solar Cells

Highway call boxes use PV cells for power. By assuming that each PV cell has an area of 0 .16 m 2 , calculate how much power it provides to the call box. As in the previous example, assume that solar power is 1 .0 × 10 3  W/m 2 and that the cells are 15% efficient.
