BuildZoom recently calculated the frequency of solar permits in the U.S., finding over 325,000 new solar power systems were added to homes last year, half of which were located in sunny California. While the Golden State remained the leader in solar sustainability, the Northeast held a 13.2 percent share of all solar permits -- up from 9 percent the year prior, according to BuildZoom. The Midwest remained the least geothermal focused in the report, with just 1.2 percent of solar permits in 2015, down from 3.2 percent in 2014. Solar permits in the South rose slightly last year, from 15.2 percent to 16.2 percent of all U.S. activity in 2015. The West, excluding California and Hawaii, grew from 13.9 percent to 15.1 percent. Highest solar permits per capita California continues to be the most solar-friendly state, holding 48.3 percent of all solar permits in the country in 2015.
