In-house W-2 crews installing Tier 1 panels and batteries on Cambridge homes. 290+ local installs already, on Eversource service. 47-day average from contract to a working system.
By the numbers
Cambridge homeowners are high-information, high-bill, high-EV-attach customers. Bundling solar + battery + EV charger is the typical Teamsun project here.
Our crew dispatches from our Bristol, CT office and reaches every Cambridge ZIP within standard service radius — no third-party crews, no "we will hire local" handoff. 290+ Cambridge homes already have a Teamsun system on the roof.
We work in Mid-Cambridge, North Cambridge, Cambridgeport, and East Cambridge Cambridge neighborhood — plus the surrounding Somerville, Boston, Watertown area.

“Teamsun was the only crew that walked the roof, named the panel brand, and answered every question without checking with someone. Same lead tech came back a year later when I added a battery.”
“Three of my neighbors had Teamsun, so I called them. The crew was on my street five days after I signed.”
“They knew the historic district secretary by first name. Saved us six weeks on permitting alone.”
“Same lead tech who installed it came back four years later to swap an inverter under warranty. No charge, no excuses.”

If your roof is over 12 years from end-of-life, we strongly recommend our solar + roofing bundle — re-roof and install solar on the same timeline. Cambridge's housing stock makes this a common scenario; we have the crew and process for it.
