Question

Solar radiation at the surface of the earth is about 700 W/m2. How much power is incident on a roof of dimensions 12.96 m by 20.43 m?

Answer 1

Our first step is to find out the area of the roof, which is:

`A=12.96*20.43=264.7728m^2`

We can then obtain the power by multiplying it to the solar radiation:

`P=264.7728*700=185340.96W`

Then, our final answer is P=185340.96W
