Electromagnetic Waves

Electromagnetic waves are waves that consist of magnetic field and electric field components perpendicular to each other. These field components are also perpendicular to the direction of propagation of the wave.

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
