Question
Chapter 10, Problem 31E
Interpretation Introduction
Interpretation:
The area of the PV cell required to build a charging station is to be calculated.
Concept Introduction:
Power input on a PV cell is the total active area of the PV cell multiplied by the solar power.
The percent of the input power that is converted into output power by a PV cell is called its efficiency.
Percent efficiency of a PV cell is 100 multiplied by the ratio of power out and power in.
The expression is as follows:
