Federal Residential Solar Tax Credit (Section 25D) Expired December 31, 2025
Laconia 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 NH state rebate was also permanently repealed (SB 303).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
Laconia pricing reflects NHEC territory and the Lakes Region installer market. No federal ITC, no state rebate — these are real 2026 out-of-pocket costs.

Prices as of March 2026. Based on Lakes Region installer data and EnergySage NH marketplace. No federal 25D ITC ($0). No NH state rebate (SB 303). No state sales tax (NH advantage).
Laconia's NHEC territory, lack of property tax exemption, and Lakes Region market dynamics shape the economics.
Laconia is primarily served by NH Electric Co-op at $0.22/kWh — the lowest rate among NH's major utilities. NEM 2.0 credits are approximately $0.19/kWh (~85% of retail). Lower rates mean lower per-kWh savings, extending payback compared to Eversource or Unitil territory.
Unlike Concord, Manchester, and Keene, Laconia has NOT adopted RSA 72:62 for solar property tax exemption. Your solar system may increase your assessed property value. This is a meaningful difference — other cities save ~$584/year from the exemption that Laconia homeowners miss.
Laconia sits on Lake Winnipesaukee and Lake Opechee, making it a tourism hub with many waterfront and vacation properties. Solar on rental/vacation homes still works but usage patterns differ. If the home is unoccupied seasonally, more energy gets exported at the lower NEM credit rate.
New Hampshire has no state sales tax at all. Unlike MA (6.25%) or VT (6%), you pay zero sales tax on solar equipment and installation. This saves $1,500+ compared to neighboring states on a typical system.
Laconia has everything from waterfront estates on Winnipesaukee to modest in-town homes and older mill housing. Waterfront homes often have larger energy demands (docks, heating, cooling) and may benefit from 10-12 kW systems. Older homes may need panel upgrades ($1,500-$3,000).
The Lakes Region has fewer solar installers than the Manchester-Nashua corridor. Less competition means higher per-watt costs ($3.05-$3.30 vs $2.85-$3.20 in Manchester). Getting 3+ quotes is even more important here to find competitive pricing.
How an 8 kW cash-purchased system pays back in Laconia with no federal credit, no state rebate, and no property tax exemption.
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. TPO may be especially attractive in Laconia given the longer cash payback period.
Laconia has the highest costs and longest payback among NH cities due to NHEC's low rate and no property tax exemption.
| City | Cost/W | 8 kW Avg | Payback |
|---|---|---|---|
| LaconiaYOU ARE HERE | $3.05-$3.30/W | $25,400 | ~12.9 yr |
| Manchester | $2.85-$3.20/W | $24,200 | ~9.3 yr |
| Concord | $3.00-$3.25/W | $25,000 | ~10.5 yr |
| Keene | $3.00-$3.20/W | $24,800 | ~11.2 yr |
Laconia's longer payback is driven by two factors: NHEC's $0.22/kWh rate (lowest in NH) and no RSA 72:62 property tax exemption. Manchester benefits from installer competition and Eversource's higher rate.
Laconia has a standard permitting process. Most residential solar permits are issued within 2-3 weeks.
Your installer submits plans to the Laconia Building Department. Standard residential solar permits include structural and electrical drawings. Typical processing: 1-2 weeks.
Physical installation of panels, inverter, and electrical connections. Waterfront properties may have specific structural requirements due to wind exposure. Most standard installations complete in 1-2 days.
Laconia electrical inspector signs off on the installation. Typically scheduled within 1 week of completion.
NEM 2.0 enrollment and bi-directional meter installation through NH Electric Co-op. Takes 2-4 weeks after passing inspection. Your installer handles the interconnection application.
Total timeline: 5-8 weeks from signed contract to system activation. Waterfront properties on Winnipesaukee may require additional structural review for wind load but this rarely adds more than a week.
Homeowners in Gilford, Meredith, and Tilton share similar solar economics with Laconia — all in the Lakes Region market.
Adjacent to Laconia on Winnipesaukee's southern shore. NHEC territory at $0.22/kWh. Many waterfront properties with high energy usage. Similar costs: $3.05-$3.30/W. Check RSA 72:62 adoption status with the Gilford assessor.
North of Laconia on the lake. Mix of NHEC and Eversource territory. If you are in Eversource territory ($0.25/kWh), payback is faster than NHEC ($0.22). Tourism-heavy economy means many seasonal properties.
South of Laconia, more of a year-round residential community. NHEC territory. Solar economics similar to Laconia but with potentially more year-round occupancy, which improves self-consumption rates and overall payback.
Three paths to solar in Laconia. Given the longer payback period, TPO options may be more attractive here than in other NH cities.
~$25,400 upfront. All NEM credits go to you. Longer payback (~12.9 years) due to NHEC's lower rate and no property tax exemption.
25-year savings: ~$42,060
$0 down, 6-8% APR typical. You own the system and keep NEM credits. Monthly payments $200-$290 for 15-20 year terms. NH has no special subsidized loan program.
Total cost with interest: ~$37K-$45K
$0 down. Financing company claims 48/48E (30%) — deadline July 4, 2026. You get reduced electricity cost. You do not own the system. Worth considering given Laconia's longer cash payback.
Monthly: ~$110-$170 (fixed PPA rate)
Solar panels in Laconia NH cost $3.05-$3.30 per watt installed in 2026, averaging about $3.18/W. For a typical 8 kW system, that is $24,400-$26,400 with an average of $25,400. 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.
No. Laconia has NOT adopted RSA 72:62 for solar property tax exemption. This means your solar system may increase your assessed property value and property taxes. This is a notable disadvantage compared to Concord, Manchester, and Keene, which have adopted the exemption and save homeowners approximately $584/year.
Laconia is primarily in NH Electric Co-op (NHEC) territory with residential rates averaging $0.22/kWh — the lowest among NH's major utilities. Under NEM 2.0, solar credits are approximately $0.19/kWh (about 85% of retail). Some areas of Laconia may be Eversource territory ($0.25/kWh). Check your utility bill to confirm your provider.
A cash-purchased 8 kW system in Laconia pays back in approximately 12-14 years. This is longer than Manchester (~9.3 years) due to two factors: NHEC's lower rate ($0.22 vs $0.25/kWh) means less savings per kWh, and Laconia lacks the RSA 72:62 property tax exemption. After payback, you still get 11-13+ years of free electricity.
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.
It depends on usage patterns. Vacation homes occupied mainly in summer generate solar during peak production months, which is good. However, if the home is empty much of the year, more energy gets exported at the lower NEM credit rate (~$0.19/kWh) instead of self-consumed at the full rate ($0.22/kWh). Year-round residents see better economics. If you rent the property, the tenant benefits from lower bills which can justify higher rents.
