Question

A panel of solar cells has an efficiency of 0.15. The total power input to the panel of solar cells is 3.2 kW. Calculate the useful power output of this panel of solar cells in kW.

Answer 1

0.48 kW

Step-by-step explanation:

Given;

Efficiency of solar panel = 0.15

Total power input of the solar panel = 3.2kW

The useful power output of the solar panel is the amount of power transmitted by the solar panel for use. It can be expressed as a function of its efficiency and total power input.

Useful power output = efficiency × Total power input

Substituting the given values;

Useful power output = 0.15 × 3.2 kW = 0.48 kW
