Home solar in New Hampshire

Net metering is still open to new home solar under the 2017 "NEM 2.0" tariff, which the PUC kept in late 2024 and now runs until Dec. 31, 2040; the state $0.20-per-watt rebate is closed.

Net metering Net metering available

Systems up to 100 kW are netted: you pay for the kWh you take from the grid minus the kWh you send back. Under the NEM 2.0 tariff, exported power earns credit for the energy and transmission parts of the bill but only part of the distribution charge. Extra credit rolls forward; you can ask for an annual payout of credit over $100 (as of the March bill) or quarterly payouts over $25. Today's tariffs end on Dec. 31, 2040, when customers move to whatever tariff is then in effect. Source

Solar laws

  • RSA 362-A:9, net metering (2026). Sets net metering for systems up to 1 MW (100 kW netted on one meter), a 100 MW program cap with later PUC tariffs, payout options, and the Dec. 31, 2040 end date for today's tariffs. Source
  • HB 1718 (2026), ch. 309 (2026). Allows energy stored in batteries, including solar-charged batteries, to be exported under net metering. Main parts take effect Jan. 1, 2027. Source
  • HB 2 (2025), state budget (2025). Closed the state Renewable Energy Fund rebate programs to new projects until further notice. Source

Community solar

Yes, in a limited way: group net metering lets members share credits from one system, and low-to-moderate income community solar projects get special treatment.

Timeline

  1. PUC Order 26,029 creates the NEM 2.0 tariff
  2. PUC Order 27,074 keeps NEM 2.0 credit levels
  3. HB 2 budget closes state renewable rebates to new projects
  4. HB 1718 (batteries in net metering) signed, ch. 309

Federal tax credits

The 30% federal tax credit for homeowners who buy solar (Section 25D) ended for systems placed in service after December 31, 2025, so buying no longer earns a federal credit. If you lease or sign a power purchase agreement (PPA), the panels belong to a company that may still claim a business credit under federal deadlines that tighten through 2027. Ask your installer whether that savings is in your price.
