Understanding Solar Energy Systems 

Solar energy uses one of the earth’s most bountiful and free renewable resources: the sun. Solar energy systems harness energy from sunlight and convert it into electricity or heat that you can use to warm your home and water saving money, electricity, and gas. There are many factors to consider when deciding if a solar energy system is right for you: structure of your home, ground-mounted verse roof-mounted, photovoltaic (commonly called PV, used to produce electricity) versus solar thermal (used to produce heat for water or air), affordability, reliability, availability of sunlight, and much more.
