2015 was a banner year for solar policy: Obama announced his Clean Power Plan, Pope Francis came out in favor of incentives for renewables and against fossil fuels, the California Public Utilities Commission announced its preliminary decision that Net Metering 2.0 should be at the retail rate (the deal’s not done; there are still extra charges), and Congress -- in the biggest surprise of all -- voted to extend the ITC for five more years.

I don’t know how much influence the solar industry had on the president and the pope, but I do know how diligently the solar industry worked toward extending the ITC and a favorable decision at the CPUC. With the ITC secure for another six years, my crystal ball for solar is clearer than last year (I did not expect the ITC renewal until the end of 2016). So here are my predictions for rooftop solar in 2016.
