Chapter 10, Problem 30E

Interpretation Introduction

Interpretation:

The surface area of the PV cells is to be calculated and whether the given array would meet the peak power demands and fit on a rooftop or not is to be explained.

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 the 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)
