Question

At what efficiency is a photovoltaic array running if insolation on the collector is 650 W/m2, the total collector area is 10 m2, the voltage across the array is 50 V, and the current being delivered is 15 A

Answer 1

Answer: 11.53 %

Explanation:

Given

area $A=10\ m^2$

Voltage V=50 V

current I=15 A

Array running at $650\ W/m^2$

Power  $P=VI=50\times 15=750\ W$

Efficiency $\eta=\frac{750}{650\times 10}\times 100=11.53\%$
