With the home solar panel industry and the electric utility industry at war, you might expect a liberal Democratic congresswoman from New York City to support the solar side. But that’s not what happened recently when Rep. Yvette Clarke decided to wade into this fight. Instead, she signed her name to a letter apparently written by utility lobbyists that warns about the risk of solar companies duping consumers.

The Federal Trade Commission (FTC) is holding a workshop on June 21 to learn about the booming rooftop solar market and how it’s affecting consumers. There are concerns on both pro- and anti-solar sides: The solar industry is hoping that the FTC will look into what they consider to be anti-competitive practices by the electric utility industry, intended to stymie the growth of solar. The utilities hope to prod the FTC to investigate allegedly unscrupulous solar companies, in the name of protecting consumers.

The FTC is inviting comment ahead of its workshop. Clarke sent a letter to the FTC commissioners expressing concern that consumers could be misled and ripped off by solar-panel installation companies. Clarke’s office also circulated the letter to other congressional offices seeking supporting signatures, according to solar industry sources.
