Not in New Hampshire?

New Hampshire runs solar the way it runs everything: no subsidies, no sales tax, no drama. What it offers instead is durable: export credits worth 80 to 85% of retail at the three investor-owned utilities, locked in through 2040. When the federal credit died in December, New Hampshire's math barely moved. EcoGen America shows you what a Granite State system really costs and which installers earn a bid.

In New Hampshire, No Subsidies Means No Surprises.

New Hampshire runs solar the way it runs everything: no subsidies, no sales tax, no drama.

What it offers instead is durable: export credits worth 80 to 85% of retail at the three investor-owned utilities, locked in through 2040.

When the federal credit died in December, New Hampshire’s math barely moved, because it was never propped up by paperwork in the first place.

EcoGen America shows you what a Granite State system really costs, around $3.03 per watt, and which installers earn a bid.

Durability-First Guidance

The 80 to 85% export credit runs to 2040. We build paybacks on terms that outlast programs, not promotions.

Quote Analysis

Built-in checks for per-watt pricing against the New Hampshire market and export credits counted at your utility's real percentage.

Local Policy

We track the three IOUs' crediting terms and the PUC decisions that lock New Hampshire's rules through 2040.

Privacy First

Your data is only shared with the licensed New Hampshire installers you choose.

What Each New Hampshire Utility Pays for Exports

New Hampshire is small enough that people assume one set of rules. There are two, and the gap between them is the biggest variable in the state.

Utility
Export Credit
Monthly Fixed Charge
What It Means
Eversource
80 to 85% of retail
Standard
The mainstream case; solid returns
Liberty Utilities
80 to 85% of retail
$14.74
Payback from roughly 9.5 years, the state’s fastest
Unitil
80 to 85% of retail
Standard
Same tariff family as the other IOUs
NH Electric Co-op
13.76¢/kWh, about 62% of retail
$29.00, the state’s highest
The weakest economics in New Hampshire
The IOU tariff pays 100% of energy and transmission plus 25% of distribution on exports, per the PUC net-metering tariff, guaranteed through 2040. Figures per our New Hampshire cost guide, July 2026.

One nuance for rate shoppers: New Hampshire is a retail-choice state, and joining a Community Power program or a competitive supplier does not change your net-metering credit; the utility still sets it. Shop your supply rate freely. The solar math stays put.

Bid, Size, Bank: Buying Solar the Granite State Way

1

Bid

With no rebates distorting prices, installer competition is the discount. Collect at least three bids; the Manchester-Nashua corridor rewards it.

2

Size

Exports earn 80 to 85% of retail, not 100, so self-consumption is worth slightly more than exporting. Size to your usage and your roof's unshaded, snow-shedding area.

3

Bank

The tariff is locked through 2040. Every utility rate increase between now and then raises what your panels save, with no program deadline to chase.

Locked Until 2040: The Quiet Guarantee

Other states have spent the decade trimming what solar owners earn: California cut exports to a fraction of retail, and utilities elsewhere file to do the same most years. New Hampshire went the other way and wrote its export credit into a tariff guaranteed through 2040.

  • Fifteen years of known rules. A system installed this year runs most of its warranty life under a compensation structure that cannot be quietly re-filed away. Few states can say that.
  • No deadline pressure, by design. There is no expiring rebate or stepping-down block here, so any salesperson manufacturing urgency is selling you something other than the tariff.
  • Group net metering catches the roofs that can’t. Households without a usable roof can share the output of a local system and receive bill credits under the same tariff family.
  • The bill never quite reaches zero. Fixed charges, $14.74 a month at Liberty up to $29 at the co-op, survive any system size. Realistic projections show them.

The whole incentive story, including what vanished in 2026 and what never existed here, is in our New Hampshire incentives guide.

New Hampshire Contract Checks

What a New Hampshire Contract Should Prove

No subsidies means nothing hides the installer's own numbers. Make every bid show these four.

Clause to verify: Ask which export credit rate the projection uses, for which utility. It should match the tariff, not round up.
Clause to verify: Confirm the racking spec and load analysis in writing, and ask how seasonal snow cover is reflected in the production estimate.
Clause to verify: Ask which of these the quote assumes, and get the all-in number, not the per-watt teaser.
Clause to verify: Request the cash price next to the financed total, and check the loan payment actually beats your current bill.
Verify your paperwork

Four checks, any bid. A New Hampshire installer with real numbers will not flinch at them.

The Homes Where New Hampshire Solar Falls Flat

No incentives also means no cushion. These are the situations where the Granite State math does not close.

  • A low-usage co-op account. The NH Electric Co-op pays 13.76¢ on exports and charges $29 a month regardless. Small usage plus weak credit plus the state’s highest fixed charge is the worst combination New Hampshire offers.
  • Deep tree shade you will not cut. New Hampshire’s canopy is beautiful and brutal. A shaded roof underperforms its model here just like everywhere else, but with no subsidies to absorb the miss.
  • A roof nearing replacement. Panel removal and reinstall costs thousands and none of it is warrantied. At $3.03 a watt untaxed, the system deserves a roof that will outlast it.
  • Moving before the high-9s. Payback starts around 9.5 years at the best-positioned utility and runs longer elsewhere. Shorter tenure rarely gets its money back.
  • Chasing backup power on savings math. A battery adds roughly $13,500 and earns little on arbitrage under this tariff. Buy storage for outages if you want it; do not let anyone sell it as an investment here.

What does not disqualify you: your supplier. Community Power and competitive-supply customers keep the same utility-set net-metering credit as everyone else. Weigh your own numbers in our worth-it breakdown. And when quotes start, our ranked top solar companies in New Hampshire is the shortlist to test them against.

New Hampshire Solar FAQs

Does New Hampshire really have no solar incentives?

Essentially, yes: no state tax credit, no state rebate, and no sales tax on anything, so nothing to exempt. Some towns offer a local property tax exemption; check yours.

What the state provides instead is the net-metering tariff itself, worth 80 to 85% of retail on exports at the investor-owned utilities and guaranteed through 2040.

What happens to my export credit when rates change?

It moves with them. The tariff pays a percentage-based credit, so every approved rate increase raises what your exports earn, automatically.

The structure itself is locked through 2040, which is a longer guarantee than nearly any other state currently offers.

I’m an NH Electric Co-op member. Is solar still worth it?

It can be, with eyes open. The co-op credits exports at 13.76¢, about 62% of its retail rate, and charges the highest fixed monthly fee in the state at $29.

A well-sized, unshaded system still recovers its cost within the panels’ life, but low-usage co-op households see the weakest returns in New Hampshire.

Do panels make sense with this much snow?

Yes, engineered properly. Cold weather improves panel efficiency; the loss comes from snow sitting on the array, which the right pitch and snow-shedding racking clears within days.

Make sure the production estimate accounts for seasonal cover and the racking spec is in the contract.

My roof can’t host panels. Any option in New Hampshire?

Group net metering. The state lets multiple accounts share the output of one system and receive bill credits under the same tariff family.

It is a smaller market than rooftop ownership, but it is the realistic fallback for shaded roofs and renters.
