Teamsun is the residential and commercial install brand of Green Enterprises, LLC, a privately owned New England company. Our Team Sunshine install arm has put solar on more than 9,000 New England roofs across Connecticut, Massachusetts, and Rhode Island.
Our crews are W-2 employees on our payroll. We do not use subcontractors. The lead tech who walks your roof at the site visit is the same lead tech who installs your system — and the same person who picks up the phone when you call about a service question in year five.
We only install Tier 1 panels and certified batteries (FranklinWH, Tesla Powerwall, Enphase IQ). Every quote names the exact panel and battery brand. Every install is designed in Aurora using your real roof, your real shade, and your real utility rate — so the production numbers on your proposal are the numbers you will actually see.
That model is slower to scale than handing roofs to subcontractors. It is also why three of your neighbors already have us on speed dial.
No franchise. No private equity. Dan answers the phone, and every dollar that funds our install crews comes from work we did last week — not a 10-year exit clock.
We name the panel brand and battery brand on every quote. FranklinWH, Tesla Powerwall, Enphase IQ — the same gear we put on our own families’ roofs.
Every crew is W-2 on our payroll. The lead tech who walks your roof at the site visit is the same one who installs the system, and the same person who picks up the phone in year five.
47 days from signed contract to a working system, on average. 5 to 15 days from final install to PTO. Tracked weekly across CT, MA, and RI.
Forty-plus years of combined management experience between our founder and senior crew leads. No call center, no offshore intake desk — when you call our Bristol office, the person who answers worked on a roof in your county within the last six months.

“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.”
