Wolfeboro, New Hampshire
Like many homeowners in Wolfeboro, New Hampshire, this family was looking to take control of their electricity costs. With Eversource rates averaging $0.27/kWh, the numbers made sense — especially with New Hampshire’s available state and utility incentive programs.
In New Hampshire, solar homeowners can benefit from programs like NEM 2.0 (~85% retail credit). Property tax exempt (RSA 72:62, ~66% of towns).
Important: The federal residential solar tax credit (Section 25D) expired on December 31, 2025. All savings calculations for this project reflect $0 federal tax credit for homeowner-purchased systems.
We designed a 12 kW system using 30 REC Alpha Pure-R 400W panels (400W each). REC Alpha panels offer industry-leading efficiency and one of the strongest warranties in the market (25-year product and performance). Their heterojunction cell technology delivers excellent performance in low-light and high-temperature conditions.
The Enphase IQ8+ microinverters convert DC to AC at each individual panel, maximizing production even when some panels are shaded. Enphase’s panel-level monitoring lets the homeowner track performance of every single panel through the Enphase app. The IQ8 series also supports Sunlight Backup — limited daytime power during grid outages even without a battery.
Equipment Reviews
New Hampshire NEM 2.0 credits solar production at roughly 85% of the retail rate (100% supply + 100% transmission + 25% distribution). Credits are locked through 2041.
Federal Tax Credit Status: The residential solar tax credit (Section 25D) expired December 31, 2025. Homeowner-purchased systems receive $0 federal tax credit. All savings estimates above are calculated without any federal credit. Third-party owned systems (leases/PPAs) may still benefit from the commercial ITC (Section 48/48E) claimed by the financing company.
“Near Lake Winnipesaukee, we wanted panels that could handle heavy snow loads. REC Alpha panels were the right choice and NuWatt's design accounts for our shading from pine trees.”
