If you have research solar power systems, and feel your home is ready for a solar system installation, you must schedule a consult from a professional solar installer. Be prepared for the consult, in order to make it efficient and accurate. A basic understanding of solar technology will aid in your understanding of what the installer tells you after your consult.

Have a year’s worth of energy bills ready, so the installer can calculate the size system you need. Your energy costs (versus your energy usage) are a better calculator of what you will need.
Once the installer determines the size system you need, it must be determined if you have enough sunlit roof space for the solar system. Panel sizes average 3 X 5 feed, and generally, 400 square feet of uncovered roof is required for a 3.5-4 kWh system.
A professional solar system installer should provide the following information. If they don’t, be sure to ask for it.
Be sure the entire proposal is in writing, as is the warranty for installation. Remember, the installer is responsible for rebates, permits and other paperwork. A reputable solar installer will be glad to provide these requests.

If you are ever in doubt about your solar system installation, it is important to get your concerns addressed, and your questions answered. Doing so will save you time, money, and unnecessary stress. Stay informed every step of the way.
When it is time to make the final decision whether or not to install a solar power system, be completely sure about your decision. If you have any doubts, wait it out, get your questions answered, and don’t make any hasty decisions. A solar power system is an expensive investment that requires construction, so be sure of your decision at all times.
