"Early distributed generation (DG) models inspired us to believe that we could all participate in the mission to democratize and decarbonize our energy infrastructure. Yet, for a long time, that was really only true for a quarter of U.S. households and businesses. For the other 75% or so, putting a solar PV system on their roof or property either wasn’t possible or wasn’t practical. Those hurdles are being addressed today through the proliferation of community solar, an adaptive DG model that has opened the door to a vast new customer base – one that includes all of us."
