We are very pleased with the installtion and operation of our Sunrun solar panel system and battery. The Tesla phone app that lets us see the energy generated by the panels, stored by the battery and used by our home is an outstanding way to track our energy consumption and consider ways to reduce it.

Never scheduled an appointment with them because I never liked them. Then suddenly I'm receiving notifications saying I have an appointment with them. They forced an appointment down into your throat. What a shady company.

The support Company, Trinity Solar/Roofing, was easy to work with and their work was satisfactory. The sales and support staff were friendly, professional and all questions were answered. The work was performed in a timely matter and communication was maintained throughout the installation process. I am awaiting answers on monitoring the Tesla Power Wall as one battery is not reporting to the app. can be monitored via the web on the Sunnov client site.

Your service. I have two bad panels that I paid for and refuse to replace. you say you are only responsible for the amount of energy productionnot responsible. Then who the hell is? You say you're only responsible for the energy production and it's doing what it's supposed to do. I say then why do I have two extra panels that I paid for if that's the case.
