As per this model, consumers do not need a good roof for panels to get power from the sun.

NRG Senior Vice President Craig Cornelius told Bloomberg in a phone interview: "These types of programs, whether with homeowners, commercial businesses or municipalities, allow us to democratize participation in renewable power consumption."

Colorado is the first state in the US to allow private players to create community solar gardens in 2010.

Unlike the usual large solar installations that provide power to utilities, community projects sell power directly to consumers, reported Bloomberg.
