There is no need to hook your solar power system onto a power grid in your area. You have the ability to be independent from the power companies in your area. In other words, you won't need to change electric services should you move, nor will you see high electric bills anymore.
Before signing any agreement for installation of solar energy products, get at least three estimates. Once the estimates are in your hand, read each one carefully to ensure that the installation is up to your standards. Each estimate should include a time frame of completion, a list of materials and the estimated amount of labor charged.

Check with your local power company as to whether they have a program to buy excess electricity collected by your solar panels. Some utility companies will give homeowners credits to apply to any energy provided to them. These programs are becoming more available as more and more people install solar panels on their home.
When the space and resources are available, your best bet for maximum solar energy gathering is a panel system with sun tracking. This type of system tracks the sun's movement across the entire day, and even the entire year. This may cost you a little more at first, but the results in the end are worth it.
