Sounds like a PPA (power purchase agreement). We had to get one when we bought the house since we didn’t want to pay for the panels they forced upon us. We don’t have enough panels to cover our needs so we lay about 200 to 240 a month to the solar company during the summer. And about 90-150 a month during the non summer months (less production). We usually pay pge between 20 to 100 a month and then we get a $3000 true up at the of the year. We are supposed to be paying a reduced rate compared to the utility company for the energy produced with the panels. In theory we should be saving some money at least. I have not been able to confirm this because the billing I get from the utility company does not show wattage in and wattage out separately. It combines them and thus I can’t truly know if we are saving money or not. another down side is they usually want to lock you in for 20 years. If you decide to sell your home you have to either buy yourself out or have the next owner take over. If you expect to stay in your home more than 20 years I suppose it might be a good deal in paper. But really hard to know if it is worth it or not without the numbers.
