Solar generates electricity. A heat pump consumes it for heating and cooling. Together, they eliminate fossil fuel bills and maximize your NEM 2.0 credits. NHSaves provides up to $6,250 in heat pump rebates. NEM 2.0 rates are locked through 2041. This is the most powerful residential energy move in New Hampshire.

Docket DE 16-576
Federal Tax Credits: 25D and 25C Both Expired
Section 25D (residential solar) and Section 25C (heat pump/energy efficiency) both expired December 31, 2025. There is no federal tax credit for homeowner cash/loan purchases of solar panels or heat pumps. NH state solar rebate (SB 303) also repealed. Only NHSaves rebates and HEAR (pending) remain.
A heat pump uses approximately 4,200 kWh per year for heating in New Hampshire. An 8 kW solar system produces approximately 9,400 kWh per year. Solar covers the heat pump electricity with 5,200 kWh to spare for the rest of your home. This combination eliminates your heating fuel bill and dramatically reduces your electric bill.

Most NH homes heat with oil (the dominant fuel). Switching from oil to a cold-climate heat pump powered by solar is the biggest financial win.

Our Recommendation
Install the heat pump first if you are replacing a failing furnace or boiler. Otherwise, install both together for the best experience. The NHSaves rebate has a December 30, 2026 deadline, and sizing solar after knowing your HP electricity consumption ensures you do not undersize or oversize the array.
New Hampshire winters demand cold-climate rated heat pumps. All models below are NHSaves qualified, use R-32 or R-454B refrigerant (required for 2026), and operate well below 0 degrees F.
Pairing these with solar maximizes the electrification benefit: the more efficient your heat pump (higher COP), the less electricity it draws, and the more solar surplus you keep as NEM credits.

A typical cold-climate heat pump in New Hampshire uses approximately 4,200 kWh per year for heating, assuming a COP of 3.0 and standard NH winter conditions. An 8 kW solar system produces approximately 9,400 kWh/year in NH, more than enough to cover the heat pump electricity plus most of your existing household electricity usage.
Yes. An 8 kW solar system in NH produces about 9,400 kWh/year. A heat pump uses about 4,200 kWh/year. That leaves approximately 5,200 kWh to offset your other household electricity. With NEM 2.0 credits at ~85% of retail rate, excess production rolls over as credits on your utility bill.
NHSaves rebates apply to the heat pump regardless of whether you have solar. Standard tier: $250/ton (max $1,250) for oil/gas/propane replacement. Enhanced tier: $1250/ton (max $6,250) for electric resistance replacement. Systems must be installed by December 30, 2026 and use R-32 or R-454B refrigerant.
We generally recommend installing the heat pump first (or both together). Installing the heat pump first lets you know your actual electricity consumption, so you can size solar accurately to cover your home plus the heat pump. If your furnace or boiler is failing, heat pump first is a clear choice. The NHSaves rebate has a December 30, 2026 deadline.
HEAR (Home Efficiency and Electrification Rebates) is PENDING in New Hampshire. The state has been allocated $34.7 million, and spring 2026 launch is anticipated. Once active, HEAR would provide up to $8,000 for low-income and $4,000 for moderate-income households, stackable with NHSaves rebates. Do not count on HEAR when making purchasing decisions today.
With an 8 kW solar system (~$24,240) and a heat pump (~$12,000) minus NHSaves rebate ($1,250-$6,250), combined annual savings of approximately $4,288 (solar savings + fuel switch savings) yields a combined payback of roughly 7 years. This assumes oil-to-heat-pump fuel switch and NEM 2.0 credits for solar production.
