What your roof actually produces here

Rockingham County averages about 4.0 peak sun hours a day. A well-oriented kilowatt of panels produces roughly 1,168 kilowatt-hours a year in this part of New Hampshire. A typical 9 kW residential system therefore produces around 10,512 kilowatt-hours annually. At a rate near 24.0¢, that production is worth roughly $2,523 a year before any incentive.

Those are pre-shading numbers. Trees, roof pitch and orientation move them, sometimes a lot, which is why we look at your specific roof rather than quoting from a county average.

Permitting and interconnection in Rockingham County

Permits for solar in Rockingham County are issued locally rather than at the state level, so requirements vary between municipalities. Interconnection is handled by your utility and runs on its own timeline after the permit clears. We manage both, and we tell you what the local process looks like before anything is scheduled.

Every New Hampshire utility rate, for context

What New Hampshire offers a homeowner

New Hampshire repealed its rebate in 2024 under SB 303. What remains is more durable than a rebate: net metering at roughly 85% of retail is written into statute through 2041, the most stable arrangement in New England.

How export credit works here

Net metering at roughly 85% of retail, in statute through 2041.

Outages and storage in Rockingham County

Solar alone does not run your house during a blackout — a grid-tied inverter has to disconnect when the grid goes down, for line-worker safety. Adding storage and the right switching changes that. Whether storage also makes financial sense in New Hampshire depends on the export credit above: where exports are credited at the full retail rate there is no arbitrage to capture and storage is a resilience purchase.

Rockingham County questions

The things people actually ask

Does solar make financial sense in Rockingham County?

It depends on your roof and your rate, not on the county. Rockingham County averages about 4.0 peak sun hours a day, so a well-oriented kilowatt of panels produces roughly 1,168 kilowatt-hours a year here. Against a rate near 24.0¢ that production has real value — but shading, roof pitch and your actual usage move the number, which is why we look at your address instead of quoting a county average.

Which utility serves Rockingham County?

New Hampshire is served by several utilities, including Eversource, Unitil, Liberty Utilities, NH Electric Co-op. Your bill names yours at the top. Enter your ZIP and we will match your address to the right one.

Where does the 24.0¢ figure come from?

It is the New Hampshire statewide average residential price published by the U.S. Energy Information Administration, as of August 2026. It is a state average rather than a verified figure for one utility's tariff, so treat it as a starting point — your own bill is the accurate number.

Does SolarAmerica install the system?

We design the system and manage the project. Installation is performed by licensed partners in your area, and you will know who is coming to your roof before anything is scheduled.

What does $0 upfront actually mean?

Under a power purchase agreement we install and own the system and you buy the power it produces at a rate set in your agreement. There is no purchase and no loan. The residential federal credit (25D) ended for systems purchased after December 31, 2025; what remains applies to the owner of the system, which under a PPA is us.
