A PV cell intercepts 585 watts of sunlight and produces 68 watts of electrical power. What is its percent efficiency?

Interpretation Introduction

Interpretation:

The percent efficiency of the given PV cell is to be calculated.

Concept Introduction:

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.

Percent efficiency=Power outPower in×100% ...... (1)

Explanation of Solution

The PV cell intercepts 585 W of sunlight and the output electrical power is 68 W.

Substitute 585 W for power in and 68 W for power out in equation (1) as follows:
