Nine services. One crew. From the first 15-minute call to the last permit signoff, every step happens inside Teamsun — no subcontractors, no handoffs, no excuses about who-said-what.
Solar, batteries, roofs — designed in Aurora and built by our in-house crews.
Custom rooftop systems for homes across CT, MA, and RI. Tier 1 panels, in-house crews, 47-day average install.
Small-to-mid commercial roofs and ground mounts. 25 kW – 500 kW range, full permitting, utility interconnection.
FranklinWH, Tesla Powerwall, Enphase IQ. Backup for outages, plus CT ESS and MA Connected Solutions program enrollment.
If your roof is under 12 years from end-of-life, we re-roof and install solar on the same timeline. One crew, one warranty.
Retrofits, upgrades, and service — even on systems we did not install.
Add a battery to a solar system any installer built — any brand, any age. The work most national installers refuse.
Older system underperforming? Inverter swap, panel addition, full repower — diagnosed first, then quoted.
Cleaning, inverter repair, monitoring fixes, animal and storm damage — for any solar system in CT, MA, or RI.
Round out your install with the pieces that pay for themselves.
Level-2 chargers wired to your solar panel by licensed in-house electricians. Eligible for utility rebates.
Cash, loan, PPA, or pre-paid lease. Our PPA underwrites at 620 FICO — the floor most nationals will not touch.
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.
A 15-minute call, then a remote or on-site visit. Aurora-based design, panel and battery brand named on the proposal.
Permits filed, utility interconnection submitted, and equipment staged at our Bristol warehouse.
Local crew, local trucks. Most homes finished in 2 – 3 days. Final inspection scheduled before we leave.
PTO from your utility, ITC and rebate paperwork filed, and 25 years of local service after the system goes live.
“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.”
A 15-minute call with a designer who knows your town. No closer on the line. No follow-up unless you ask for one. $0 down options available.
