“NuWatt was upfront that the federal tax credit was gone. Every other company I talked to still had it in their proposals. That honesty is why I went with them. System has been producing above estimates for 8 months.”
“From the first call to flipping the switch, NuWatt handled everything. SMART enrollment, net metering paperwork, even coordinating with our historic district commission. Truly full-service.”
“We got quotes from three companies. NuWatt was the only one that explained the difference between cash purchase and the Propel lease option. No pressure, just clear options. Our electric bill dropped 85%.”
Answers to common questions about solar installers in Massachusetts.
The best solar installers in Massachusetts are NABCEP-certified, locally based, and transparent about 2026 pricing. NuWatt Energy has completed over 2,500 installations across Massachusetts, holds NABCEP certification, and is one of the few MA installers that honestly discloses the Section 25D tax credit expiration. Look for installers who handle SMART 3.0 enrollment and ConnectedSolutions signup as part of the installation.
Solar installation in Massachusetts costs $3.00-$3.20 per watt in 2026. A typical 10 kW system costs $30,000-$32,000 before state incentives. The federal residential tax credit (Section 25D) expired December 31, 2025, so there is no federal credit for cash or loan purchases. After the $1,000 MA state tax credit, SMART 3.0 income, and net metering savings, payback is typically 8-11 years.
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 solar lease or PPA where a third-party owner claims the Section 48 commercial ITC and passes savings to you as lower monthly payments. NuWatt offers this through our Propel financing program.
Massachusetts has the strongest state solar incentives in the country: SMART 3.0 pays $0.03/kWh for 20 years, 1:1 net metering credits your bill at full retail rate, ConnectedSolutions pays $225-$275/kW annually for battery owners, a 15% state tax credit (up to $1,000), 20-year property tax exemption, and 6.25% sales tax exemption on solar equipment and labor.
From signed contract to system power-on, most Massachusetts residential solar installations take 8-12 weeks. This includes engineering and design (1-2 weeks), permitting (2-4 weeks), installation (1-2 days), electrical inspection, and utility interconnection with Permission to Operate (2-4 weeks). NuWatt handles all permitting and utility paperwork.
NuWatt Energy serves all of Massachusetts including Greater Boston, North Shore, South Shore, MetroWest, Central MA, Pioneer Valley, Cape Cod and the Islands, and Merrimack Valley. We install in both Eversource and National Grid territories as well as municipal utility areas.
When you buy solar (cash or loan), you own the system and keep all production value, but the federal 25D tax credit is $0 in 2026. When you lease through NuWatt's Propel program, a third-party financing company owns the system, claims the Section 48 commercial ITC (30%), and passes those savings to you as a lower monthly payment. You get $0 down, immediate savings, and a 25-year warranty.
NuWatt installs Hyundai 440W (entry tier), Silfab 440W (FEOC-qualified, required for Propel lease), and REC 460W (premium tier) solar panels paired with Enphase IQ8 microinverters. For battery storage, we offer Tesla Powerwall 3, Enphase IQ batteries, and Franklin aPower2 systems. All equipment includes manufacturer warranties of 25 years.
