Hays Energy Services did a fantastic job installing 44 350W solar panels on our concrete tile roof. Another installer planned to order a palette of tiles, since they expected to break many tiles during installation. Hays' installers were able to do the installation without breaking a single tile.
Plus the installation looks great because they ran the conduits through the attic, instead of across the roof!
They also installed 4 Tesla PowerWalls. Because they have experienced electricians, we had confidence they would design an implementation that would correctly with our house.
They installed the system in late 2019 - and almost a year and a half later, we haven't had a single problem with the system!
Would highly recommend them - especially based on the quality of their solar panel installation and experienced electricians.
