“Yesterday in Lancaster, homebuilder KB Home celebrated its 1,000th new home with solar panels from SunPower,” reports the website Greentech (“California City Wants to Require Solar on Every New Home,” by Herman K. Trabish). “Speaking at the event, Mayor Parris announced his city will institute a first-of-its-kind requirement that solar be installed on every new single-family home built in Lancaster after January 1, 2014.” Under Parris’ proposed ordinance, houses on lots from 7,000 square feet must have a solar system of 1.0 kilowatt to 1.5 kilowatts. But builders will be able to average the solar capacity of different houses together, as long as the total installed solar equals the per-house minimum.
