NH solar costs $2.85-$3.25/W installed. Average: $3.03/W. No sales tax saves $1,500+. No federal credit. No state rebate. Here is the real breakdown — every dollar accounted for.
The federal 25D tax credit expired December 31, 2025. The NH state rebate was repealed by SB 303 in 2024. You are paying the full installed cost of your solar system. Any estimate that shows 30% federal credit or $1,000 state rebate is wrong. NuWatt's prices reflect 2026 reality.
Three panel options at three price points. All include Enphase microinverters, racking, permitting, and full installation.
Lowest installed cost. Strong cold-weather performance. Best for fastest payback.
FEOC-compliant. Required for Propel lease. North American manufactured.
Highest efficiency and snow-load rating. Best temp coefficient for NH cold.
Typical cost breakdown for an 8 kW system at ~$3.03/W ($24,240 total).
Varies by tier (Hyundai, Silfab, REC)
Microinverters — no single point of failure
Engineered for NH snow loads
Wiring, conduit, disconnect, meter
Licensed electricians + roofers
Town permit + utility NEM 2.0 enrollment
Structural analysis, electrical plans
Insurance, vehicles, office, profit

For a standard residential installation (composition shingle roof, good sun exposure, standard electrical panel), anything above $3.50/W in NH likely includes:
Exceptions: Steep-pitch roofs, tile roofs, multi-plane layouts, significant electrical panel upgrades, or EV charger additions can legitimately push costs above $3.50/W.
Competitive pricing, entry-tier panels
Premium panels, standard installation

The 25D residential ITC expired December 31, 2025. Any estimate showing a 30% credit on cash/loan is using expired data. Run.
SB 303 repealed the state rebate in 2024. It no longer exists. If an installer shows $1,000 in state rebate savings, they have not updated their software.
Unless you are installing on a complex roof (multiple planes, steep pitch, tile), $3.50/W or higher suggests excessive overhead. Get a second quote.
If an installer says you will get 1:1 net metering, they do not understand NH rules. NEM 2.0 credits at ~85% of retail, not 100%. This affects your payback calculation.
A good NH installer should know whether your town has adopted the property tax exemption and help you file it. If they have never heard of RSA 72:62, question their NH expertise.
NH electricity rates average $0.27/kWh — 65% above the national average. NEM 2.0 credits are locked through 2041. Property tax exemptions add ~$584/yr in qualifying towns. Even without the ITC, the math works because your electricity costs are already high and rising at 3-5% annually.
