Federal Residential Solar Tax Credit (Section 25D) Expired December 31, 2025
Hudson 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 NH state rebate was also permanently repealed (SB 303).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 guide
Hudson pricing reflects Eversource NH territory and strong installer competition from both NH and MA companies along the Route 3A corridor. No federal ITC, no state rebate — these are real 2026 out-of-pocket costs.

Hudson's Eversource territory, property tax exemption, MA border installer competition, and suburban housing stock shape the economics.
Hudson 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.
Hudson has adopted RSA 72:62, exempting solar energy systems from property tax. Your 8 kW system adds $0 to your assessed value, saving approximately $584/year based on Hillsborough County mill rates.
Hudson directly borders Massachusetts. Both NH-based and MA-based solar installers compete for Hudson jobs, driving down pricing. You get quotes from Nashua, Lowell, and greater Boston-area companies all vying for your business.
New Hampshire has no state sales tax at all. Unlike MA (6.25%) next door, you pay zero sales tax on solar equipment and installation. This saves $1,500+ compared to Lowell or Tewksbury homeowners just across the border.
Hudson is predominantly 1960s-80s subdivisions with standard asphalt shingle roofs and good south-facing exposure. Newer construction off Route 111 and near the Nashua border is also ideal for solar. Most suburban lots have minimal shading.
Hudson 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.
How an 8 kW cash-purchased system pays back in Hudson 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.
Hudson's MA border location, commuter demographics, and suburban housing stock make it one of southern NH's best opportunities for residential solar.
Hudson sits directly on the Massachusetts border along Route 3A, just minutes from Nashua and a short commute to Lowell, Burlington, and Boston. Many residents earn Massachusetts salaries while enjoying NH's zero income tax and zero sales tax. High household incomes mean strong purchasing power for solar, and many homeowners are pairing EV chargers with their solar systems.
Hudson's housing stock is predominantly 1960s-80s subdivisions with standard asphalt shingle roofs and good south-facing exposure. Newer developments near Route 111 and the Nashua border have modern roof designs well-suited for solar. Unlike dense urban areas, most Hudson lots have minimal tree shading on the south side, reducing the need for expensive tree removal.
Hudson offers lower property tax rates than neighboring Nashua, making it attractive for families who want the Nashua-area amenities at a lower cost. With RSA 72:62 adopted, solar adds $0 to your tax bill. Many homeowners who moved to Hudson for the tax advantage find that solar further reduces their monthly expenses, especially when combined with CPCNH's lower supply rates.
Hudson's western edge follows the Merrimack River, giving the town a distinctive mix of riverside properties and inland subdivisions. Riverside homes may have more tree coverage requiring shade analysis, but the vast majority of Hudson's residential areas — especially the neighborhoods along Route 3A and Route 111 — have excellent solar exposure with no historic district restrictions on rooftop installations.
Hudson's MA border location and installer competition keep pricing in line with or below neighboring towns.

Salem uses Liberty Utilities at $0.24/kWh (slightly lower rate, slightly longer payback). Nashua has slightly higher costs due to urban density. All four towns have adopted RSA 72:62 property tax exemptions.
Hudson has a straightforward permitting process. Most residential solar permits are issued within 2-3 weeks.
Your installer submits plans to the Hudson Community Development Department. Standard residential solar permits include structural and electrical drawings. Typical processing: 1-2 weeks.
Physical installation of panels, inverter, and electrical connections. Most Hudson homes with standard roofs are completed in 1-2 days.
Hudson 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. Hudson has no historic district solar restrictions for standard residential installations.

Solar panels in Hudson NH cost $2.85-$3.15 per watt installed in 2026, averaging about $3.00/W. For a typical 8 kW system, that is $22,800-$25,200 with an average of $24,000. 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. Hudson 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 Hillsborough County mill rates. This is a permanent exemption with no expiration.
Hudson 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 Hudson pays back in approximately 9-10 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 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.
