Solar power increases for businesses and utilities in Wisconsin led to three times more solar power installations for 2015 than any other before, according to numbers from Renew Wisconsin.

Seven-and-a-half megawatts of solar power, enough energy to power 1,000 average sized homes, were installed in 2015, Tyler Huebner, Renew Wisconsin executive director, said. In previous years, he said, only two to three megawatts were installed, and most increases were residential rather than industrial.
