“NuWatt was the only company that told me straight up — the federal tax credit is gone. They showed me how the Efficiency Maine rebate and net metering still make solar a great investment. System is outperforming their estimate.”
“We got three quotes. NuWatt handled our CMP interconnection paperwork, the Efficiency Maine rebate, and even helped with our town building permit. Everything was seamless from start to finish.”
“Being in Versant territory, I was worried about finding a solar company that knew our utility. NuWatt handled everything — net metering, rebates, all of it. Our electric bill went from $240/month to a $12 connection fee.”
Answers to common questions about solar installers in Maine.
The best solar installers in Maine are NABCEP-certified, locally based, and experienced with both CMP and Versant utility territories. NuWatt Energy has completed hundreds of installations across Maine, holds NABCEP certification, and honestly discloses that the Section 25D federal tax credit expired December 31, 2025. Look for installers who handle Efficiency Maine rebate paperwork and net metering enrollment as part of the installation.
Solar installation in Maine costs $3.00-$3.20 per watt in 2026. A typical 10 kW system costs $31,000 before the Efficiency Maine rebate ($0.40/W up to $4,000). After the rebate, a 10 kW system costs about $27,000. The federal residential tax credit (Section 25D) expired December 31, 2025, so there is no federal credit for cash or loan purchases.
No. The Section 25D residential solar tax credit expired December 31, 2025. If you purchase a solar system with cash or a loan in 2026, your federal credit is $0. The only way to access federal incentives is through a third-party ownership model like NuWatt's Propel financing ($4.00/W max in Maine), where a financing company claims the Section 48 commercial ITC and passes savings to you as lower payments.
Maine offers the Efficiency Maine rebate ($0.40/W up to $4,000 for systems up to 10 kW), 1:1 retail rate net metering credits, 100% property tax exemption on solar equipment value, and no sales tax on solar equipment. For qualifying homeowners, Propel financing (available in Maine) provides $0 down with lower monthly payments through third-party ITC capture.
Yes. NuWatt Energy installs solar across all of Maine, including both CMP (Central Maine Power, covering ~80% of the state) and Versant Power (covering Bangor, Downeast, and Northern Maine). We handle all interconnection paperwork and net metering enrollment for both utilities.
Propel is a Concert Loan + Prepaid ESA available in Maine at $4.00/W max. A third-party financing company owns the system and claims the Section 48 commercial ITC (30%+), passing those savings to you as a lower price. You get $0 down, 25-year warranty, and immediate savings. Propel requires FEOC-qualified Silfab 440W panels. It is not a lease or PPA.
From signed contract to system power-on, most Maine residential solar installations take 6-10 weeks. This includes engineering and design (1-2 weeks), permitting and Efficiency Maine rebate application (2-3 weeks), installation (1-2 days), electrical inspection, and utility interconnection with Permission to Operate (2-3 weeks). NuWatt handles all permitting and utility paperwork.
Maine gets 50-80 inches of snow annually, but solar panels are installed at an angle that helps snow slide off. Cold temperatures actually improve panel efficiency by 10-15% compared to summer heat. NuWatt installs snow guards on every Maine system and designs for annual production of 4.3 peak sun hours. Most Maine systems produce 85-90% of their annual output between March and October.
