Question
The Intensity of solar radiation at the Earth's orbit is 1370 W/m2. However, because of
the atmosphere, the curvature of the Earth, and rotation (night and day), the actual
intensity at the Earth's surface is much lower. At this moment, let us assume the
intensity of solar radiation is 575 W/m2. You have installed solar panels on your roof to
convert the sunlight to electricity.
If the area of your solar panels is 4 m2, How much power is incident on your array?
Watts
Submit Answer
Tries 0/2
Unfortunately, solar panels are only about 20% efficent...Only 1/5 of the light is
converted to electricity. This being the case, how much electrical power are you
actually producing for your home at this moment?
Watts
