The Georgia Public Service Commission is going after some rooftop solar installers who are making promises they can’t keep.

Commission Chairman Tricia Pridemore has sent a letter urging state Attorney General Chris Carr to protect Georgia homeowners from rooftop solar panel installers advertising free electricity and free solar.

The PSC approved a pilot program two years ago allowing 5,000 homeowners to install solar panels on their rooftops and sell any excess energy produced back to Georgia Power. That 5,000 cap was reached this summer, and representatives of the solar industry have been urging the commission to raise the limit.

False ads being run by disreputable rooftop solar installers are misrepresenting the pilot program, regulators and utilities, Pridemore wrote to Carr.

“The solar developer industry is self-regulated, but there are clear and decisive laws against misleading advertisements,” Pridemore wrote. “I implore the attorney general’s office to protect hard-working Georgia homeowners from these scams and companies who seek to damage the exceptional reputation of Georgia’s utility system.”
