A decade ago, someone knocking on your door to sell you solar panels would have been selling you solar panels. Now, they are probably selling you a financial product—likely a lease or a loan.

Mary Ann Jones, 83, didn’t realize this had happened to her until she received a call last year from GoodLeap, a financial technology company, saying she owed $52,564.28 for a solar panel loan that expires when she’s 106, and costs more than she originally paid for her house.

In 2022, she says, a door-to-door salesman from the company Solgen Construction showed up at her house on the outskirts of Fresno, Calif., pushing what he claimed was a government program affiliated with her utility to get her free solar panels. At one point, he had her touch his tablet device, she says, but he never said she was signing a contract with Solgen or a loan document with GoodLeap. Unbeknownst to Jones, the salesman used “[email protected]” as her purported email address—that of course, was not her email address. She’s on a fixed income of $960 a month, and cannot afford the loan she says she was tricked into signing up for; she’s now fighting both Solgen and Goodleap in court.

Her case is not uncommon. Solar customers across the country say that salespeople obscure the specific terms of the financial agreements and cloud the value of the products they peddle. Related court cases are starting to pile up. “I have been practicing consumer law for over a decade, and I’ve never seen anything like what we are seeing in the solar industry right now,” says Kristin Kemnitzer, who represents Jones and says her firm gets “multiple” calls every week from potential clients with similar stories.
