If you value your money, do not do business with Performance Solar. I previously hired them to re-install solar panels; 5 years later a panel was leaking from damage from a hail storm. I was told to leave a credit card for the $127.50 service fee, not realizing that ethical firms do not require a down payment. Friday morning, the repairmen show up unannounced. They go up and they come down from the roof and tell me that I need two panels replaced but they dont have that particular panel with them. They ask if I would like to add another panel to the system. I say no, I just want the panels replaced. I wait another week. Finally, around 3:00 pm, I call them. You need three panels replaced at $600 apiece. We will replace your system for only $3000. Remember that service charge? A week later, the service charge shows up. I will pay this fee but I will tell the world not to do business with Performance Solar. You can find panels for half the price online. Caveat emptor, indeed.
