Solar sounds great; reality has not been very good. Graveyard of companies in the business - especially for residential use. A few reasons why: a) animals (squirrels, birds, etc.) get in underneath the panels and cause issues, b) they often result in a leaky roof - and have to be totally torn off to replace the roof - very expensive, c) challenges when extreme wind. The ONLY system I'm aware of from friends that remain in the business is from GAF. The reason is that the solar panels ARE THE ROOF TOO -- so they don't experience the issues most all other systems have. Hope that helps.
