Chapter 10, Problem 34E

Interpretation Introduction

Interpretation:

The area of the PV cells required to run the air conditioner is to be determined and some good reasons to use solar power for air conditioning units are to be stated.

Concept Introduction:

Power input on the 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 to 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.

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

$\text{Average solar power}=\frac{\text{Power input}}{\text{Surface area}}$
