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.
Keep your solar panels out of the shade. It might seem obvious, but your solar panels do need sun. Make sure that you are not installing them in the shade. Trim back the branches on surrounding trees if you need to. Failing to do so could cost you more than half your energy output.
