Manchester solar costs $2.85–$3.20 per watt in 2026. A typical 8 kW system runs $22,800–$25,600. As the Queen City and largest municipality in NH (115K population), Manchester has the most installer competition and some of the best pricing in the state.

Manchester pricing reflects Eversource NH territory and the city's competitive installer market. No federal ITC, no state rebate — these are real 2026 out-of-pocket costs.

Prices as of March 2026. Based on Manchester-area installer data and EnergySage NH marketplace. No federal 25D ITC ($0). No NH state rebate (SB 303). No state sales tax (NH advantage).
Manchester's Eversource territory, property tax exemption, and competitive installer market shape the economics.
Manchester is served by Eversource NH at $0.25/kWh. NEM 2.0 credits are approximately $0.21/kWh (~85% of retail). Credits roll over indefinitely with cash-out at $100. Rates are locked through 2041 under Docket DE 16-576.
Manchester has adopted RSA 72:62 at town meeting, exempting solar energy systems from property tax. Your 8 kW system adds $0 to your assessed value, saving approximately $584/year based on the local mill rate.
Manchester participates in the Community Power Coalition of NH (CPCNH). Community Power can lower the supply portion of your bill by 5-15%. Solar customers still get NEM credits through Eversource for delivery and transmission.
New Hampshire has no state sales tax at all. Unlike MA (6.25%) or CT (6.35%), you pay zero sales tax on solar equipment and installation. This saves $1,500+ compared to neighboring states on a typical system.
Manchester has a mix of mill-era housing, triple-deckers, and newer suburban construction. Older homes in the downtown and Millyard area may need electrical panel upgrades ($1,500-$3,000). Newer neighborhoods like Hooksett border areas are straightforward.
As the largest city in NH (115K population), Manchester has the most installer competition. More quotes drive better pricing. Average costs here run slightly below statewide averages due to installer density.
The federal 25D credit is dead and NH repealed its state rebate. But four mechanisms still reduce your effective cost or improve payback in Manchester.
~85% of retail rate (~$0.21/kWh on Eversource). Credits roll over indefinitely. Locked through January 1, 2041.
Formula: 100% supply + 100% transmission + 25% distribution. NOT 1:1 retail.
Manchester has adopted RSA 72:62. Solar adds $0 to assessed value. Saves ~$584/year permanently.
~66% of NH towns have adopted this. Manchester is confirmed.
NH has no sales tax at all. Saves $1,500+ vs. MA (6.25%) or CT (6.35%) on a typical system.
This is a statewide NH advantage, not a solar-specific program.
Third-party system owners (lease/PPA companies) still claim 30% ITC on systems beginning construction before July 4, 2026.
You do not own the system. The TPO provider passes savings via lower monthly payments.
Expired December 31, 2025. Homeowners who buy with cash or a loan receive $0 in federal tax credits.
SB 303 (signed 2024) permanently repealed the $0.20/W state rebate. No state solar rebate exists in NH.
How an 8 kW cash-purchased system pays back in Manchester with no federal credit and no state rebate.
While homeowners can no longer claim the 30% ITC directly, Section 48E still allows third-party system owners (lease and PPA companies) to claim a 30% investment tax credit on residential solar systems. The deadline: construction must begin before July 4, 2026.
Timeline alert: To meet the July 4, 2026 “begin construction” deadline, you need to sign a PPA/lease agreement by mid-May at the latest. Manchester permitting takes 2-3 weeks, plus Eversource interconnection adds 2-4 weeks. Full Section 48E guide for NH homeowners
Manchester has the most installer competition in NH, which helps keep pricing competitive despite being the largest metro.
| City | Cost/W | 8 kW Avg | Payback |
|---|---|---|---|
| ManchesterYOU ARE HERE | $2.85-$3.20/W | $24,200 | ~9.3 yr |
| Nashua | $2.90-$3.25/W | $24,600 | ~9.5 yr |
| Concord | $2.85-$3.15/W | $24,000 | ~9.1 yr |
| Portsmouth | $2.95-$3.30/W | $25,000 | ~9.2 yr |
Concord has a slightly faster payback due to Unitil's higher rate ($0.26/kWh). Portsmouth costs more per watt (seacoast premium) but also has a fast payback due to higher property values.
Manchester has a straightforward permitting process. Most residential solar permits are issued within 2-3 weeks.
Your installer submits plans to the Manchester Building Department. Standard residential solar permits include structural and electrical drawings. Typical processing: 1-2 weeks.
Physical installation of panels, inverter, and electrical connections. Most Manchester homes with standard roofs are completed in 1-2 days.
Manchester electrical inspector signs off on the installation. Typically scheduled within 1 week of completion.
NEM 2.0 enrollment and bi-directional meter installation. Takes 2-4 weeks after passing inspection. Your installer submits the interconnection application.
Total timeline: 5-8 weeks from signed contract to system activation. Manchester has no historic district solar restrictions for residential installations.
Three paths to solar in Manchester. Each has different economics now that the federal credit is gone.
~$24,200 upfront. All NEM credits and property tax savings go to you. Best long-term value with ~8.6-year payback.
25-year savings: ~$72,407
$0 down, 6-8% APR typical. You own the system and keep NEM credits. Monthly payments $190-$270 for 15-20 year terms. NH has no special subsidized loan program.
Total cost with interest: ~$34K-$42K
$0 down. Financing company claims 48/48E (30%) — deadline July 4, 2026. You get reduced electricity cost. You do not own the system.
Monthly: ~$120-$180 (fixed PPA rate)
Solar panels in Manchester NH cost $2.85-$3.20 per watt installed in 2026, averaging about $3.03/W. For a typical 8 kW system, that is $22,800-$25,600 with an average of $24,200. There is no federal tax credit (25D expired December 31, 2025) and no NH state rebate (SB 303 repealed it). The price you see is the price you pay.
Yes. Manchester has adopted RSA 72:62, which exempts solar energy systems from local property tax assessment. Your solar system adds $0 to your assessed home value. This saves approximately $584 per year based on a typical 8 kW system adding ~$15,000 in value at Manchester mill rates. This is a permanent exemption with no expiration.
Manchester is in Eversource NH territory with residential rates averaging $0.25/kWh. Under NEM 2.0, solar credits are approximately $0.21/kWh (about 85% of retail). The NEM 2.0 formula is 100% supply + 100% transmission + 25% distribution. Credits roll over monthly indefinitely, with cash-out at the $100 threshold. Rates are locked through January 1, 2041.
A cash-purchased 8 kW system in Manchester pays back in approximately 9.3 years. This factors in $0 federal tax credit, $0 state rebate, NEM 2.0 credits at ~$0.21/kWh, property tax exemption savings of $584/year, and 2.5% annual rate escalation. After payback, you generate free electricity for the remaining 15+ years of panel life.
No, if you buy with cash or a loan. Section 25D (the 30% residential solar ITC) expired December 31, 2025. However, if you go with a third-party owned system (PPA or lease), the financing company can still claim Section 48E (30%) on systems that begin construction before July 4, 2026. The TPO provider passes some of that savings to you as a lower rate.
Section 48E is the commercial/third-party clean energy investment tax credit (30% base rate). While homeowners cannot claim it directly, solar lease and PPA companies can claim 48E on systems they own and install on your roof, as long as construction begins before July 4, 2026. This means Manchester homeowners who choose a lease or PPA still benefit from a 30% credit indirectly through lower monthly payments. After July 4, 2026, this pathway closes too.
Manchester homeowners still have four active incentive mechanisms in 2026: (1) NEM 2.0 net metering at ~85% of retail rate, locked through 2041; (2) Property tax exemption under RSA 72:62, saving ~$584/year; (3) No state sales tax on solar (NH has 0% sales tax); and (4) Section 48E lease/PPA option through July 4, 2026 where the financing company gets 30% ITC. The federal 25D residential credit ($0) and NH state rebate (SB 303 repealed) are both gone.
