With the stroke of a pen, Governor Brown could now save California building owners an average of a $1000 off the cost of installing rooftop solar.  That’s the estimate from Lawrence Berkeley National Lab in analyzing the impact of streamlining local permitting regimes in California.  AB 2188 (Muratsuchi) seeks to do just that — streamline local processes and end additional burdens from homeowner’s associations on rooftop solar.  The bill is now headed to the governor’s desk.  As I wrote about earlier this month, California can’t control the cost of solar PV, but it can get its collective local houses in order when it comes to permitting solar.
