You may want to check out a company called Solstice (www.solstice.us). They specialize in community solar, especially for those that are low income and living in apartments/multi-family homes. They are successful and are bringing solar to communities and residents that are not rich. Certainly, solar started out as something for the rich. But prices have come down dramatically, and solar is now moving into the masses. Many states, like Hawaii have 10% or more renewables now. We can move to 100% renewable grid affordably...Bill Buchan, P.E.
