    Reviewed Mar 31, 2021

    We are going into our third summer with an 8 KWH rooftop system installed by Granite State Solar. The system is performing as promised, and the installation has been trouble-free, with the exception of one connection to a microinverter that worked loose, but was fixed quickly. Staff has always been responsive to my questions. We are now considering adding an Enphase 10 KWH battery to the system.

    Thank you so much for your review! We're so glad to hear that you've been happy with your system year after year and we look forward to hopefully working with you again on your battery.
