Get Ready for the Rooftop Solar Stall
This was supposed to be solar’s moment. Residential panel installations in the U.S. grew 71 percent in 2015 as the falling cost of panels made the power they generate more competitive. In December, Congress unexpectedly extended a tax credit set to expire at the end of 2016. . . Yet instead of energizing the industry, the extension has hurt growth, as solar companies no longer rush to meet a deadline. After jumping more than 1,000 percent since 2010, panel installations are projected to grow by only 0.3 percent in 2017, according to Bloomberg New Energy Finance.
