As you may have heard, starting in 2020, California will require that all new single-family homes include a solar power system. (At present, about one in five new homes has solar added when built.) This will help California meet its ambitious goals regarding greenhouse gas emissions, and will continue California's leadership in home energy efficiency.
We hear a lot about the "cost" of solar when utilities attempt to weaken net metering rules. "Solar is only for the wealthy," they say. "Poorer ratepayers subsidize every rooftop solar installation out there." "Why should the poorest ratepayers help pay for a more affluent person's solar system?"
