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.

Keep shade issues in mind when installing solar panels. A panel that loses a quarter of its light can lose half its power production. The main thing to keep in mind is tree foliage. Are any trees going to grow in between the panels and sunlight? Consider trimming them back a little.
