Solar built for your roof, your bill.

A typical 8 – 12 kW Teamsun system runs $25,000 – $40,000 before incentives. Residential ITC no longer applies in New England, but with our high energy costs, state rebates, and full retail net metering, our systems still save homeowners money — typically 30 – 50% lower effective cost over the first five years.

47 days on average. About 7 – 10 days for the site visit and design lock, 20 – 30 days for permitting and utility interconnection, one day on the roof for most systems, and 5 – 15 days for utility approval (PTO) once we close it out.

No. Every Teamsun residential install is done by W-2 employees on our payroll. The crew lead who walks your roof at the site visit is the same crew lead who installs your system, and the same person who picks up the phone if you call about a service question in year five.

Tier 1 only — REC Group, Q CELLS, and Silfab as our default brands. The exact panel and inverter brand are named on every proposal. We do not swap brands at install without explicit re-approval.

Yes. We size your inverter and electrical panel to be battery-ready on every install, even if you defer the battery to a later date. We also retrofit batteries onto systems we did not install — most installers refuse this work.

Residential ITC no longer applies in New England, but state and utility incentives still carry the math: CT ESS battery rebates start at $5,000 (up to 100% of battery cost by location), MA Connected Solutions performance payments, full retail net metering across all three states, plus CT property and sales tax exemptions on the system value. Commercial systems remain eligible for up to 40% federal ITC. We file every form with you.

Yes. Our PPA underwrites at 620 FICO — the floor most national installers will not touch. You pay $0 down and a fixed monthly rate that is typically below your current utility bill from day one.

If your roof is over 12 years from end-of-life, we strongly recommend bundling. We re-roof and install solar on the same timeline — one crew, one contract, one warranty. See the solar + roofing service.

You call our Bristol office at 203-903-4091 and a person picks up. Manufacturer warranties cover panels for 25 years, inverters for 10 – 25 years, and batteries for 10 – 15 years. We service systems we installed and ones we did not.

We use Aurora to model production based on your real roof geometry, your real shade (from satellite imagery), and your real utility rate schedule. Estimates are conservative on purpose — most of our customers see equal or higher production than the proposal predicts.
