Before you can understand why solar energy is important you should have a good idea of what solar energy is. Solar energy is produced by the sun. It can be harnessed like any other type of energy and used to create electricity to run homes and businesses. Buildings can also be heated by the thermal energy produced by the sun. Best of all, solar energy is free and does not compromise the environment.
If you have ever gotten in a warm car on a sunny winter day, you have experienced the thermal energy of the sun. The sun's rays move through the glass of the car and warm the interior, although it may be quite chilly outside. Likewise, some people have actually baked cookies on the dashboard of their car on hot summer days. Again, thermal energy is being used.
In order to harness the energy from the sun and turn it into electricity, it is necessary to have solar cells to collect and transform solar energy into useable electricity. These cells are typically in the form of panels that face the direction of the sun to capture the most rays possible.
