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 %

Step-by-step 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* 15=750\ W`

Efficiency
`\eta=(750)/(650* 10)* 100=11.53\%`
