Portland is Maine's densest rooftop market — historic housing stock, CMP net metering, and strong battery interest for coastal storm backup. Crews stage from Bristol with dedicated project days for greater Portland.
Our crew dispatches from our Bristol, CT office and reaches every Portland ZIP within standard service radius — no third-party crews, no "we will hire local" handoff. 140+ Portland homes already have a Teamsun system on the roof.
We work in West End, East End, Deering, and Munjoy Hill Portland neighborhood — plus the surrounding South Portland, Westbrook, Scarborough area.

What customers say
Trusted by homeowners
Trusted by homeowners
who value quality.
“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.”
Portland FAQ
Questions Portland homeowners ask.
How much does solar cost in Portland?
A typical 8 – 12 kW residential install in Portland runs $25,000 – $40,000 before incentives. Residential ITC no longer applies in New England, but with high regional energy costs and Maine state programs, effective residential costs still land 30 – 50% lower over the first five years. Commercial systems also stack up to 40% federal ITC. We model your specific roof in Aurora using Central Maine Power rate data.
Does Teamsun install in my Portland neighborhood?
Yes — we work across West End, East End, Deering, Munjoy Hill and surrounding Portland ZIPs. 140+ Portland homes already have a Teamsun system. The crew dispatches from our Bristol, CT office.
How long does the install take in Portland?
47 days on average from signed contract to a working system, including Portland permitting and Central Maine Power interconnection. The on-roof portion is typically just one day. We file every form on your behalf.
What incentives can I claim as a Portland homeowner?
Maine net metering (CMP or Versant), Efficiency Maine heat-pump and weatherization stack-ons where eligible, and commercial systems can still claim up to 40% federal ITC. We model your utility tariff on every proposal. Teamsun files every form with you — commercial federal ITC paperwork is handed to your CPA, state and utility paperwork we submit on your behalf as part of the install.
Do you use subcontractors on Portland installs?
No. Every Teamsun install — in Portland and across our entire CT, MA, and RI service area — is done by W-2 employees on our payroll. The lead tech who walks your roof at the site visit is the same lead tech who installs your system.
What if my Portland home has an older roof?
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. Portland's housing stock makes this a common scenario; we have the crew and process for it.
Can I add a battery to existing solar in Portland?
Yes — see our battery retrofit service. Maine net metering and Efficiency Maine stack-ons accept retrofitted batteries on existing solar. Most national installers refuse this work; we built a team around it.
Are you licensed to do work in Portland?
Yes — Teamsun is licensed in Maine (and ME, NH, VT, FL for project work on request). License numbers, NABCEP certification, and BBB profile are all available on every quote and contract.
