__Solar Panels__
> > ==== ====
 * When the photons that are in the sunlight hit the electrons in the solar cells, some electrons are let loose and that's what makes the electric current. Solar panels collect the energy for homes and businesses. They are an alternative to paying for electricity from the energy companies. Many people use solar panels now instead of paying for electricity from the companies because it is much more 'green' and it's much less expensive.

__Solar Panel Locations__

 * The location of solar panels is very important for getting the most energy and the most sunlight. 90 degrees is the preferrable tilt angle for the most amount of sunlight. The locations for solar panels are usually on roofs or in big open that get a lot of sunlight such as fields. Solar panels come in many sizes. The bigger ones go in the fields and the smaller ones go on peoples' houses.

 * Solar cells where discovered in 1876 by William Grylls Adams and a student of his, Richard Day. They discovered that when selenium was exposed to light, it made electricity. The selenium cells were not efficient at all, but that was when it was proved that light, without moving parts or heat, could be made into electricity.

This is a sketch of a solar panel. The white stripes are where where the electrons would be. The rest is black so it will attract the sun.
