These homeowners didn’t have a good roof for solar on the house, so they had us install solar electric on the flat rubber roof of their garage. The solar is covering 35% of their electricity needs. Some people might be disappointed to only offset 35% of their bill, when their neighbors are eliminating bills altogether. But consider the savings. This system is delivering more than $1,300 worth of clean electricity a year. Over 25 years with inflation factored in, the savings will be $53,685, substantially more than the system price tag.
