Concord solar costs $3.00–$3.25 per watt in 2026. A typical 8 kW system runs $24,000–$26,000. As the state capital of New Hampshire (population ~44,000 in Merrimack County), Concord benefits from Unitil's higher rates which accelerate solar payback.

Federal Residential Solar Tax Credit (Section 25D) Expired December 31, 2025
Concord homeowners who purchase solar with cash or a loan receive $0 in federal tax credits. NH state rebate was also permanently repealed (SB 303). All prices below reflect what you actually pay. PPA/lease providers can still claim Section 48/48E (30%) through July 4, 2026. Full NH solar cost guide
Concord pricing reflects Unitil NH territory. No federal ITC, no state rebate — these are real 2026 out-of-pocket costs.

Prices as of March 2026. Based on Concord-area installer data and EnergySage NH marketplace. No federal 25D ITC ($0). No NH state rebate (SB 303). No state sales tax (NH advantage).
Concord's Unitil territory, state capital permitting, and property tax exemption shape the economics.
Concord is served by Unitil NH at $0.26/kWh — one of the higher rates in the state. NEM 2.0 credits are approximately $0.22/kWh (~85% of retail). Credits roll over indefinitely with cash-out at $100. Rates are locked through 2041 under Docket DE 16-576.
Concord 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.
As the state capital (population ~44,000), Concord has a well-staffed building department and straightforward permitting. The city is progressive on renewable energy and actively participates in CPCNH Community Power.
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.
Concord has a mix of historic New England homes near downtown and newer suburban development in the Heights and east side. Older homes may need electrical panel upgrades ($1,500-$3,000). Homes in Bow, Hopkinton, and Pembroke share similar characteristics.
Unitil's $0.26/kWh rate is higher than Eversource ($0.25) and Liberty ($0.24). Higher rates mean more savings per kWh of solar production, partially offsetting Concord's slightly higher install costs compared to Manchester.
How an 8 kW cash-purchased system pays back in Concord with no federal credit and no state rebate.
Third-Party Ownership (TPO) Still Has the ITC
If you go with a PPA or lease, the financing company claims Section 48/48E (30%) on systems beginning construction before July 4, 2026. You get a lower monthly rate because of it. You do not own the system and NEM credits typically go to the system owner.
Concord has higher per-watt costs than Manchester due to fewer competing installers, but Unitil's higher rate improves payback.
| City | Cost/W | 8 kW Avg | Payback |
|---|---|---|---|
| ConcordYOU ARE HERE | $3.00-$3.25/W | $25,000 | ~8.6 yr |
| Manchester | $2.85-$3.20/W | $24,200 | ~9.3 yr |
| Keene | $3.00-$3.20/W | $24,800 | ~11.2 yr |
| Laconia | $3.05-$3.30/W | $25,400 | ~12.5 yr |
Manchester has the lowest costs due to installer competition. Laconia has the longest payback due to NHEC's lower rate ($0.22/kWh). Concord's Unitil rate ($0.26/kWh) helps offset its higher install costs.
As the state capital, Concord has a professional building department and efficient permitting process for residential solar.
Your installer submits plans to the Concord Building Department (41 Green St). Standard residential solar permits include structural and electrical drawings. Typical processing: 1-2 weeks.
Physical installation of panels, inverter, and electrical connections. Most Concord homes with standard asphalt roofs are completed in 1-2 days.
Concord 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 to Unitil.
Total timeline: 5-8 weeks from signed contract to system activation. Concord has no historic district solar restrictions for residential installations. The downtown area is straightforward for permits.
Homeowners in Bow, Hopkinton, and Pembroke share similar solar economics with Concord — all served by Unitil with comparable rates and costs.
Just south of Concord, Bow is also Unitil territory at $0.26/kWh. RSA 72:62 adoption varies by town — check with Bow's assessor for property tax exemption status. Similar cost range: $3.00-$3.25/W.
West of Concord in Merrimack County. Mix of Unitil and NHEC territory depending on location. More rural properties may have better south-facing roof exposure. Costs similar to Concord.
East of Concord along the Merrimack River. Eversource territory at $0.25/kWh (lower rate than Unitil). Slightly different payback math but comparable install costs: $3.00-$3.20/W.
Three paths to solar in Concord. Each has different economics now that the federal credit is gone.
~$25,000 upfront. All NEM credits and property tax savings go to you. Best long-term value with ~8.6-year payback.
25-year savings: ~$74,673
$0 down, 6-8% APR typical. You own the system and keep NEM credits. Monthly payments $200-$285 for 15-20 year terms. NH has no special subsidized loan program.
Total cost with interest: ~$36K-$44K
$0 down. Financing company claims 48/48E (30%) — deadline July 4, 2026. You get reduced electricity cost. You do not own the system.
Monthly: ~$125-$190 (fixed PPA rate)
Solar panels in Concord NH cost $3.00-$3.25 per watt installed in 2026, averaging about $3.13/W. For a typical 8 kW system, that is $24,000-$26,000 with an average of $25,000. 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. Concord 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 at Concord mill rates. This is a permanent exemption with no expiration.
Concord is in Unitil NH territory with residential rates averaging $0.26/kWh. Under NEM 2.0, solar credits are approximately $0.22/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 Concord pays back in approximately 10-12 years. This factors in $0 federal tax credit, $0 state rebate, NEM 2.0 credits at ~$0.22/kWh, property tax exemption savings of $584/year, and 2.5% annual rate escalation. After payback, you generate free electricity for the remaining 13-15+ 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 48/48E (30%) on systems that begin construction before July 4, 2026. The TPO provider passes some of that savings to you as a lower rate.
Concord solar costs $3.00-$3.25/W, slightly higher than Manchester ($2.85-$3.20/W) due to fewer installers competing in the capital region. However, Concord has the advantage of Unitil's higher rate ($0.26/kWh vs $0.25) which means more savings per kWh produced. Both cities have RSA 72:62 property tax exemption.
