What the adoption figure means
A mature market by national standards, which usually means several credible installers to compare and a permitting process that is not learning on your job.
Residential electricity in New Hampshire averaged 23.40¢ per kilowatt-hour in 2024, 9th of 51 and above the national average of 16.48¢. Electricity here is dear by national standards, so self-consumption carries more value than it does in most of the country. Prices and adoption across all 51.
System size and consumption
The average New Hampshire system was 8.06 kW in 2024, ranking 13th of 51. Households consumed an average of 7,428 kilowatt-hours a year (42nd of 51) — the figure a system here is sized against.
Size your own system from your own kilowatt-hours, not from this average — how to do that.
Who owns the systems
25.7% of New Hampshire systems were third-party owned in 2024 — leased or under a power purchase agreement rather than owned by the householder. That is 14th of 51.
Third-party ownership is the dominant model, so expect a lease or PPA to be the first thing you are offered. Who claims the federal credit · ownership across all 51.
Battery attachment
3.19% of New Hampshire solar systems were paired with a battery in 2024, 14th of 51 — 718 paired systems.
Attachment is well above average, so storage is a normal part of a quote here rather than an upsell. Attachment across all 51 · does a battery belong in your project.
Where the market is going
New Hampshire added 3,372 systems in 2024 and has grown at 20.8% a year over five years, 34th of 51. Where growth has turned.
Solar companies and licensing in New Hampshire
We found no dedicated state licence register for solar work in New Hampshire, so we publish no company counts rather than guessing. That is not evidence of light regulation — electrical work is frequently licensed at state or local level even where solar is never named separately.
It does have a practical consequence here. With 22,503 systems in the state and adoption 14th of 51, you are working in a market where a search for "New Hampshire solar licence" will often return nothing useful, and where the company quoting you may be travelling in from out of state. Ask which licence they hold, in which state, and confirm it with that issuing authority rather than accepting a licence number on a proposal. What to do when the search comes back empty.
Method
Figures are computed by HyreSolar from the Form EIA-861 2024 annual files — net-metered residential systems only, penetration counted against residential accounts, sizes as means. EIA publishes the inputs, not these ratios. Full methodology and the underlying CSV.

Common questions
How many homes in New Hampshire have solar?
22,503 residential net-metered systems were recorded in New Hampshire in 2024, against 652,608 residential electricity accounts — 3.45% of households, 14th of 51 jurisdictions. That is a HyreSolar calculation from Form EIA-861.
What size solar system is typical in New Hampshire?
The average net-metered residential system in New Hampshire was 8.06 kW in 2024, against a national average of 6.74 kW. Your own system should be sized from twelve months of your kilowatt-hours and your usable roof, not from a state average.
Do people in New Hampshire add batteries to solar?
3.19% of New Hampshire systems were paired with storage in 2024, 14th of 51. Battery attachment tracks outage frequency and export rules more than it tracks sunshine.
Is New Hampshire a good state for solar?
On the measures we can compute: residential electricity averages 23.40¢/kWh (9th of 51), households use 7,428 kWh a year (42nd of 51), and 3.45% have installed a system (14th of 51). Retail price and export rules move the answer far more than sunshine does, and both are set by your specific utility rather than by the state.
