If you are thinking about using solar power in your home, you must consider how much direct sunlight your home is actually exposed to. In order for solar energy to be worth it, your roof should have full sun exposure a minimum of 6 hours every day. You should also be wary of any areas of your roof covered by shade.

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.
The best time to incorporate solar power into the design of a home or building is in the initial construction. Windows are best facing south to let maximum sunlight (hence greenhouse heat) in during the winter. Likewise, avoid windows facing directly into the summertime sun to keep things cooler, so less power is needed for fans or air conditioning. The maximum roof space, however, should always get sunlight exposure.
