The Best
You will be amazed if you use GMS From the initial phone call to the site visit to the install one word Perfect.The office staff is the best we have dealt with.The site visit no pressure went through all questions again perfect.The Tesla battery install again perfect.When the crew arrived they were polite & told us their names.They worked like a well oiled machine very neat & cleaned up when done.Stayed on site until all internet programs were done. The one big thing was the respect they all showed during the process.This is old school service . From start to finish this company will not fail you.

Responsive, Reliable Service
GMS designed our system and did the installation in June. 15 panels on two roof pitches, each with its own microinverter. GMS answered our many questions, were patient as we compared them with a quote from another contractor, and were prompt in responding to all communications. This was a key factor in choosing their service, given spotty communication from the other vendor. The installation was neatly done in one day, with connections between the two panel arrays and to the gable end done within the attic rather than routed across the roof. Panels were producing on day 1 via a temporary meter that GMS installed pending the power company installation of the dedicated meter a few days later. System monitoring via an app shows each individual panel performance and overall system output.

Happy in Brookfield
Gms was professional, and gave us an honest competitive quote. Work was completed quickly, and system looks and works great! Very pleased!
