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

Answer:

$A = 1.056\,m^{2}$

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:

$A = \frac{\dot E}{\eta \cdot I}$

$A = \frac{75\,W }{(0.1)\cdot (710\,\frac{W}{m^{2}} )}$

$A = 1.056\,m^{2}$
