For homeowners with Sunnova, SunPower, or PosiGen solar leases
Is your solar company shortchanging you?
Your servicer went bankrupt, but your production guarantee usually didn't. SunStrong, Sunrun, and Renewbrook just aren't going to volunteer to pay it. We check your actual output against your lease's guarantee for free, and draft the claim letter if you're owed money.
Most true-up periods come back with nothing owed, and we'll tell you that too, for free. $99 only if we find real money on the table.
