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:

$\text{Percent efficiency}=\frac{\text{Power out}}{\text{Power in}}\times 100$ …… (1)
