Solar energy is made out of the sun. People can get it from solar panels and solar energy can be used by the sunlight and the rays from the sun. The solar panels will last about 15-30 years in till you have to get a new panels. The cost for the solar p.v. costs only $0.16 and the solar thermal only cost $0.25. The bad thing is that the panels can kill birds and bugs because the heat can shot them. Solar energy can be used for buildings, and framers can use them for their crops. It the sun is covered the panels will use the heat that it really have in it.
