Solar Energy Science

Julia Said:

What is the science behind solar energy?

We Answered:

Basically a solar panel absorbs the light, light contains energy it transforms that energy into electricity to use just like any other electricity.

Roland Said:

How do I do a science fair on solar energy with a thermoelectric generator? How would I ask the question?

We Answered:

The first question would be "How does the temperature of a thermoelectric device effect the electrical output?" You can measure the temperature fairly easily while measuring the intensity of sunlight is more difficult.
The most likely question about waste heat would be one of these two: "Can electricity be produced from the low level of waste heat from a house heating system?" "Is it cost effective to install thermoelectric generators in the heating system of a house?"
