Question

A photovoltaic array of (solar cells) is 10.0% efficient in gathering solar energy and converting it to electricity. show answer Incorrect Answer 50% Part (a) If the average intensity of sunlight on one day is 710 W/m2, what area, in square meters, should your array have to gather energy at the rate of 75 W

Answer 1

`A = 1.056\,m^(2)`

Step-by-step explanation:

The portion of solar energy converted into electric energy is given by the following equation:

`\dot E = \eta \cdot I\cdot A`

The area needed to produce energy is derived by clearing the corresponding variable:

`A = (\dot E)/(\eta \cdot I)`

`A = (75\,W )/((0.1)\cdot (710\,(W)/(m^(2)) ))`

`A = 1.056\,m^(2)`
