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.

If you are looking for a solar energy system, make sure to ask your friends and neighbors about their experiences with various companies. A recommendation, or a warning, that you are familiar with can help you to make a smart buying decision. Your friends can also let you know about their experiences after installation, including any warranty issues and cost savings the system has offered.
