Karen R.
Simmitri replaced our roof and installed solar panels at the same time, which saved us a lot of hassle. The crew was punctual and thorough. System is performing well and the roof looks great.
Mark D.
Very professional from start to finish. Simmitri's team explained every step of the process. The Enphase system they installed is easy to monitor and our electricity costs have dropped significantly.
Angela S.
Good experience. Simmitri was thorough in their energy assessment and recommended the right-sized system for our home. Installation took one day. Minor scheduling delay at the start but otherwise smooth.
