Talk to your local government about doing any major solar installations in your home or business. You want to be properly permitted and within building, zoning and construction codes and regulations. However, you may also discover tax credits, rebates and other financial incentives. They may also have data and information about how well certain solar technologies work in your area.
Always use non abrasive cleansers on your solar panels. An abrasive cleaner can scratch the surface of the panel and cause permanent damage and affect how well the solar panel works. There are commercial cleaning solutions to use or you can use a pool skimmer with a very soft cloth on it.
Have you ever been without power during a winter storm, resulting in you freezing and all your refrigerated food going bad? Instead of using a generator which will only run some of the power in your house, use solar energy. Swapping over your system can really help you to prevent power failures in the future.
