- Rochester power is expensive, which is what makes solar pay. New Hampshire residential electricity averages about 27.33 cents per kWh (EIA, as of May 2026), well above the national average.
- Your utility is Eversource New Hampshire, the former Public Service of New Hampshire (PSNH), which serves Rochester and Strafford County (NH Department of Energy).
- New Hampshire credits the power you export at less than the full retail rate, so size your system close to your own use (NH Public Utilities Commission).
- Rochester adopted a local solar property-tax exemption of $50,000 or the added assessed value of the system, whichever is less (City of Rochester Assessing).
- The 30% federal homeowner credit (Section 25D) ended for systems placed in service after December 31, 2025 (IRS), and the state rebate is closed.
Rochester, New Hampshire is the Lilac City in Strafford County, one of the Tri-Cities alongside Dover and Somersworth, and its homeowners pay well above the national average for electricity. That high rate is the single biggest reason rooftop solar pays off here. The catch in New Hampshire is the local detail: your utility is Eversource NH, the state credits the extra power you send to the grid at less than the full retail rate, the federal homeowner tax credit just ended, and the state rebate is closed, but Rochester itself does offer a local property-tax break on solar. This page lays out what solar actually costs in Rochester, how Eversource NH net metering works, which incentives still exist, and the local roof factors to plan around, then you can check your own address in about a minute.

The 60-second answer for Rochester (2026)
- Rochester’s power is expensive, which is what makes solar pay. New Hampshire residential electricity averages about 27.33 cents per kWh (EIA, as of May 2026), well above the national average, so every kilowatt-hour your roof makes offsets an expensive one you would otherwise buy.
- Your utility is Eversource NH. Rochester sits in Eversource New Hampshire’s electric territory, the former Public Service of New Hampshire (PSNH), so your net metering runs through Eversource (NH Department of Energy, as of August 2026).
- New Hampshire does not credit your exports 1:1. Under the state’s default net metering, a typical home is credited for the power it sends back at less than the full retail rate (NH Public Utilities Commission, as of August 2026). See how New Hampshire net metering is calculated.
- Rochester offers a local property-tax exemption on solar. The City of Rochester adopted the RSA 72:61-62 exemption, worth $50,000 or the added assessed value of your system, whichever is less (City of Rochester Assessing, as of August 2026).
- The state rebate is closed and there is no state income or sales tax to exempt. New Hampshire’s residential solar rebate stopped taking new applications, and the state has no general sales tax and no wage income tax, so there is no state solar sales-tax exemption or income-tax credit to claim (U.S. DOE Alternative Fuels Data Center, as of August 2026).
- The 30% federal homeowner credit (Section 25D) ended after December 31, 2025 (IRS, as of January 1, 2026), so a Rochester homeowner who buys solar in 2026 cannot claim it.
Why Rochester’s electric rates make solar worth it
The reason solar pays in Rochester is the price of the power it replaces. New Hampshire residential electricity averages about 27.33 cents per kWh (EIA, as of May 2026), one of the higher rates in the country, and Eversource NH delivery plus supply is what a Rochester household actually pays each month. So every kilowatt-hour your roof makes offsets an expensive grid one. A typical Rochester home spending $150 or more a month on electricity is a strong solar candidate. For the exact cents on your own bill, read the supply and delivery lines on your Eversource statement, since both reset on a schedule.
Your production is what turns that high rate into savings. Rochester gets a solar resource typical of southeastern New Hampshire, and a well-placed roof offsets a large share of a normal home’s annual use. A 6 kW system at a Rochester ZIP models to about 7,797 kWh a year in NREL’s PVWatts (PVWatts, ZIP 03867, as of August 2026), with the winter months lighter and summer heavier. New England snow cuts a few weeks of winter output, but panels shed snow as they warm and the long summer days more than balance the year. Because output depends on your roof’s pitch, shading, and orientation, estimate your specific roof with the free PVWatts calculator rather than a generic number.
Rochester solar payback estimate (MySolarFY analysis, August 2026). We put the real local rate against the modeled production and a benchmark installed cost so you can see where the 10-to-12-year payback comes from. These are estimates for a typical cash purchase, before financing costs, and with no federal 25D credit (it ended after December 31, 2025) and no state rebate in 2026; your own numbers depend on your roof, usage, and quotes.

Your Rochester utility is Eversource NH
For electricity, Rochester is Eversource New Hampshire territory. Eversource NH is the former Public Service of New Hampshire (PSNH), the state’s largest electric utility, and it serves Rochester and the surrounding Strafford County communities (NH Department of Energy; Eversource New Hampshire rates and tariffs, as of August 2026). Your solar interconnection, your Permission to Operate, and your net-metering credits all run through Eversource NH. You may buy your electricity supply from a competitive supplier while Eversource still handles delivery, but either way the delivery utility and the net-metering account are Eversource. For the full utility picture, see our Eversource New Hampshire solar guide and the statewide New Hampshire solar guide. Nearby, the same Eversource NH rules apply in Dover, Rochester’s Tri-Cities neighbor.
How Eversource NH credits the power your roof sends back
Net metering is the engine of your savings, but New Hampshire’s version is not a full one-for-one deal. When your panels make more than your home uses in a moment, the extra flows to the grid. Under New Hampshire’s default net-metering tariff for residential systems (100 kW and under), Eversource credits that exported energy at less than the full retail rate, because the credit covers the energy charge plus only part of the delivery charge rather than the whole bundled rate (NH Public Utilities Commission, as of August 2026). The power you use in real time, as your panels make it, still offsets the full retail rate, so the more of your own solar you use on-site the better your economics.
The practical takeaway: size your system close to your own usage rather than aiming to bank a big year-round surplus, because exported power is worth a bit less than the power you consume directly. For the exact formula and how the credit rolls forward, see how New Hampshire net metering is calculated and the plain-English guide to net metering.
| What happens to your solar power | How it is valued in NH | Who benefits |
|---|---|---|
| Power you use as your panels make it | Offsets the full retail rate you would have paid | You, on your Eversource NH bill |
| Power you export to the grid | Credited at less than full retail, not 1:1 | You, as a net-metering credit on the account |
| A lease or PPA system’s output | Set by your contract, not by net metering | The third-party owner keeps incentives; you get a power rate |
New Hampshire incentives and Rochester’s property-tax exemption
New Hampshire is an honest case: the money math leans on net metering and the high local rate, not on a stack of state incentives. But Rochester adds one local break the state does not. Here is the real picture for a Rochester homeowner in 2026.
- Rochester offers a local solar property-tax exemption. New Hampshire lets each town choose to exempt the added home value from a solar system under RSA 72:61-62, and the City of Rochester has adopted it, worth $50,000 or the added assessed value of the qualifying system, whichever is less, effective for the tax year beginning April 1, 2024 (City of Rochester Assessing; NH RSA 72:62, as of August 2026). You apply through the city Assessing Department, so confirm the current form and filing deadline before you budget around it.
- The state residential solar rebate is closed. New Hampshire’s Residential Renewable Electrical Generation rebate stopped accepting new applications, so a new Rochester project cannot count on it (U.S. DOE Alternative Fuels Data Center, as of August 2026). If an installer quote still assumes the rebate, ask them to confirm its current status in writing.
- No state sales tax means nothing to exempt. New Hampshire has no general sales tax, so unlike many states there is no solar sales-tax exemption to apply for; your equipment simply is not taxed at purchase.
- No state wage income tax means no state solar income-tax credit. New Hampshire does not tax earned income, so there is no state income-tax solar credit like the ones some New England states offer.
Because the statewide rules are set at the state level rather than by your utility, we keep the full detail on our New Hampshire solar guide rather than repeating all of it here.
What the federal tax-credit change means for Rochester
The federal homeowner credit is gone, so the local case rests on net metering, the high rate, and Rochester’s property-tax break. The 30% federal Residential Clean Energy Credit (Section 25D) ended for systems placed in service after December 31, 2025, under the One Big Beautiful Bill Act, so a Rochester homeowner who buys solar with cash or a loan in 2026 cannot claim it (IRS Residential Clean Energy Credit, as of 2026). You will still see installer pages and search results asking whether the 30% credit is going away; the accurate answer for 2026 is that the homeowner version already ended. For the full timeline, see what the federal solar tax credit change means in 2026. MySolarFY does not provide tax advice; consult a tax professional about your own situation.
One federal exception exists, and it is not yours to claim. A separate commercial credit, Section 48E, is claimed by the business that owns a leased or PPA system, not by the homeowner (IRS Clean Electricity Investment Credit, as of 2026). On a leased system you do not file for a federal credit yourself; the company that owns the panels does. The Section 25D homeowner credit, by contrast, ended after December 31, 2025.
Going solar on a Rochester home
Rochester’s mix of housing is what shapes its solar projects. As a former mill and shoe-manufacturing city on the Cocheco and Salmon Falls rivers, downtown Rochester has older wood-frame homes, while the areas spreading north and out along the Spaulding Turnpike toward the Lakes Region are newer single-family homes on larger, less-shaded lots that often make excellent solar candidates. Two checks matter most here. First, many older Rochester homes still run a 100-amp electrical service panel that may need an upgrade to carry a modern solar system, especially with a battery, EV charging, or heat pumps. Second, an older or steeply pitched roof usually needs a structural look, and if your roof is near the end of its life it is worth reroofing before panels go up.
Note: Rochester sits in a real New England snow belt, so winter output dips and your installer should plan array tilt and layout with snow shedding in mind. Panels keep producing through winter, they warm and shed snow, and the long summer days carry most of the annual total. A local installer who knows Rochester roofs and City of Rochester building and electrical permitting will handle the structural review, any panel upgrade, and the Eversource NH interconnection paperwork.
| Rochester roof or site factor | What to plan for |
|---|---|
| Newer suburban home on a larger lot | Often low shading and good roof area; strong solar candidate |
| Older downtown wood-frame home | Structural check and roof-condition review before install |
| 100-amp service panel | May require a service upgrade for solar plus a battery or EV charging |
| Tree cover on a wooded lot | Shade study; fewer, higher-efficiency panels may beat a big array |
| New England snow load | Tilt and layout for snow shedding; expect lighter winter output |
Paying for solar in Rochester: cash, loan, lease, or PPA
Installed residential solar in New Hampshire runs in the mid-$3-per-watt range before any incentives (U.S. DOE solar cost benchmarks, as of 2026), so a 6 kW system for a typical Rochester home works out to roughly $18,500 to $21,000 up front, which is the basis for the 10-to-12-year payback in the quick answer above. There is no single right way to pay for that; the best fit depends on whether you want to own the system or avoid an up-front cost. Because there is no federal homeowner credit in 2026 and no state rebate, the choice hinges more on cash flow and net-metering value than on chasing a credit. A lease or PPA can mean no up-front cost for eligible homeowners, but it is a long-term agreement with monthly payments, not free, and the system owner, not you, keeps any incentive and the local property-tax exemption. To weigh the long-run numbers, see whether solar panels are worth it.
| Path | Up-front cost | Who owns the system | Best when |
|---|---|---|---|
| Cash purchase | Full system cost | You | You want the fastest payback and the most lifetime savings |
| Solar loan | Little to none, financed | You | You want ownership without paying cash up front |
| Lease or PPA | $0-up-front where eligible | The third-party owner | You prefer no up-front cost and a simpler, fixed monthly bill |
How to choose a solar installer in Rochester
Rochester homeowners can draw on local New Hampshire companies as well as regional and national brands, which is good for you because it means real competition on price and service. Rather than chasing a “best installer” list, screen any company against objective criteria:
- NABCEP certification, the industry’s professional standard for PV installers.
- Proper New Hampshire electrical licensing and a written business record you can verify.
- A clear workmanship and equipment warranty in writing.
- Real experience with Eversource NH interconnection and City of Rochester permitting, plus a plan for snow and any needed panel upgrade.
- A written production estimate and a transparent quote that does not assume the closed state rebate or any incentive that no longer applies in 2026, and that accounts for the Rochester property-tax exemption. For a checklist, see the right questions to ask a solar installer.

Frequently asked questions
Are solar panels worth it in Rochester, NH in 2026? For most owner-occupied Rochester homes with decent sun, yes. New Hampshire residential electricity averages about 27.33 cents per kWh (EIA, as of May 2026), well above the national average, so every kilowatt-hour your roof makes offsets an expensive grid one. A typical 6 kW system here models to about 7,797 kWh a year in PVWatts, which offsets roughly $1,980 to $2,130 a year at the Eversource NH rate. Savings are not guaranteed and depend on your roof, usage, and how you pay, but the high local rate, net metering, and Rochester’s local property-tax exemption make it a workable solar market even though the federal 25D credit ended after December 31, 2025 and the state rebate is closed.
Who is my electric utility for solar in Rochester? Eversource New Hampshire, the former Public Service of New Hampshire (PSNH). Rochester and the surrounding Strafford County area are in Eversource NH’s electric territory, so your interconnection, Permission to Operate, and net-metering credits all run through Eversource (NH Department of Energy, as of August 2026). You can buy your electricity supply from a competitive supplier, but Eversource still handles delivery and your solar credits.
Does Rochester, NH offer a solar tax break? Yes, a local one. The City of Rochester adopted the RSA 72:61-62 property-tax exemption for solar, worth $50,000 or the added assessed value of your system, whichever is less, effective for the tax year beginning April 1, 2024 (City of Rochester Assessing, as of August 2026). You apply through the city Assessing Department. There is no state income-tax or sales-tax break, because New Hampshire has neither tax, and the state rebate is closed.
How does net metering work with Eversource in New Hampshire? When your panels make more than you use, the extra flows to the grid and Eversource credits your account, but New Hampshire’s default net metering values that exported power at less than the full retail rate, not one-for-one, because the credit covers the energy charge plus only part of the delivery charge (NH Public Utilities Commission, as of August 2026). Power you use in real time still offsets the full retail rate, so using more of your own solar on-site improves your economics. See our New Hampshire net metering guide for the full formula.
What happened to the federal solar tax credit? The 30% federal Residential Clean Energy Credit (Section 25D) ended for systems placed in service after December 31, 2025, under the One Big Beautiful Bill Act, so a Rochester homeowner who buys solar in 2026 with cash or a loan cannot claim it (IRS, as of 2026). A separate commercial credit, Section 48E, can apply to leased and PPA systems, but the business that owns the system claims it, not the homeowner. New Hampshire net metering was not affected, so at Rochester’s high rate the local payback case still holds. MySolarFY does not provide tax advice; consult a tax professional.
Is this Rochester, New Hampshire or Rochester, New York? This page is about Rochester, New Hampshire, in Strafford County, served by Eversource New Hampshire, ZIP codes starting 03867. It is a different city from Rochester, New York, which is served by RG&E and has different rates, incentives, and net-metering rules. If you meant New York, see our Rochester, NY solar guide.
Can I get solar in Rochester with no up-front cost? Some homeowners can, through a lease or power purchase agreement (PPA) where eligible, which can mean no out-of-pocket cost at installation in exchange for monthly payments. This is not a giveaway; it is a long-term agreement, typically 20 to 25 years, and total payments may exceed the cost of a cash purchase. On a lease or PPA the third-party owner, not you, keeps any incentive and the local property-tax exemption, while your benefit is a lower or fixed power price. There is no program that installs solar at no cost with nothing in return. If you want to own the system and capture the savings yourself, a cash purchase or solar loan is the path that keeps them. Check what you qualify for before deciding.
