Before deciding on the best way to use solar electricity at home, assess the potential solar energy that can be produced at your address. Because PV technologies use both direct and scattered sunlight to create electricity, the solar resource across the United States is ample for home solar electric systems.
However, the amount of power generated by a solar energy system at a particular site depends on how much of the sun’s energy reaches it, and the size of the system itself.
Several mapping services and tools are available to help you determine your home’s solar energy potential. Some of the services also offer information on the estimated system size, potential costs and savings, and local contractors.
