Congressman Richard Hanna is co-sponsoring legislation aimed at providing critical data on the benefits of solar net metering.

Under the bill, the U.S. Department of Energy would be tasked with conducting a study on the practice that allows residential solar customers to sell excess energy produced back to the grid at retail rates.

“What we’ve seen across the country is the rapid growth of the solar industry as an affordable energy source,” Hanna said. “With net metering, customers can become energy self-sufficient and return their excess capacity back to the grid in exchange for credits, benefiting all of us."

Hanna says the cost of solar power installation today is nearly half of what it was just five years ago.  Through the end of 2014 more than 640,000 homes and business had installed on-site solar.

Congressman Brian Higgins of New York is co-sponsoring the legislation.
