Most New England homes still heat with oil or propane. A cold-climate heat pump replaces that fuel cost with electricity — and a solar array turns that electricity cost into a long-term asset. The two systems are designed for each other: solar generates what the heat pump consumes, and the heat pump electrifies the load that makes solar financially powerful. See our full solar services and HVAC services for what each trade covers individually.
Solar Powers the Heat Pump
Since both systems run entirely on electricity, they pair seamlessly. During the day your panels generate clean electricity that runs your heat pump directly. In the evening, net metering credits from daytime surplus offset what the heat pump pulls from the grid overnight. A typical heat pump adds 2,000 to 6,000 kWh of annual load — size your solar system 2 to 3 kW larger than a solar-only design to cover it.
Built for New England Winters
Modern cold-climate heat pumps are specifically engineered for the Northeast. They maintain efficient heating performance at temperatures well below freezing — a fundamentally different category of equipment than standard heat pumps from a decade ago. We install cold-climate certified equipment on every New England project, sized through a Manual J load calculation for your home's actual heat loss, not a square-footage guess.
Coordinated Installation
Coordinating solar and heat pump on a single project eliminates duplicate mobilizations, overlapping permit timelines, and the scheduling gap between two separate contractors. One project manager handles both scopes — solar design, roofing coordination, heat pump sizing, electrical, and permitting — all moving in sequence toward a single turn-on date. See our bundles page for multi-service project structure.
Required First Step in MA
Massachusetts requires a Home Energy Assessment before Mass Save rebate applications can be processed for heat pump projects. The assessment evaluates your home's insulation, air sealing, and existing heating system — and often identifies additional efficiency improvements that stack with the heat pump and solar incentives. We coordinate the assessment timing so it doesn't delay your project start.
Both Systems Earn Rebates
The solar and heat pump incentive programs in New England are separate and stackable — you don't have to choose between them. Massachusetts alone stacks the Mass Save heat pump rebate, the SMART solar performance program, and the Mass Save 0% HEAT Loan. Other states have their own equivalents. We document every applicable program on your quote and handle the filing paperwork end-to-end.
The Complete Electrification Stack
Add battery storage to solar and a heat pump and you're running the full New England electrification system — solar generates, the heat pump consumes efficiently, and the battery stores surplus for evenings and outages. In Massachusetts, battery storage also unlocks ConnectedSolutions income. In Vermont, the GMP BYOD program pays up to $10,500 in upfront battery rebates.

Solar + Heat Pump Incentives by State
Every New England state has active rebate and incentive programs for both solar and heat pumps in 2026. Here's the current stack — solar and heat pump programs run independently and stack on the same project:
- Massachusetts — Mass Save Heat Pump Rebate Up to $10,000 for qualifying whole-home cold-climate heat pump installations, calculated at approximately $2,650 per ton. Requires a prior Home Energy Assessment. Stacks with the SMART solar program and the 0% Mass Save HEAT Loan up to $25,000 for 7 years.
- Massachusetts — SMART Solar Program Performance-based solar incentive paying a fixed rate per kWh produced over a 10 to 20-year term through your utility. Adding battery storage increases the SMART payout rate. Enroll at the same time as interconnection filing.
- New Hampshire — NHSaves Heat Pump Rebates NHSaves offers rebates of approximately $1,250 to $2,500 for qualifying cold-climate heat pump installations, depending on your utility (Eversource or Unitil) and system type. Stacks with NH net metering on the solar side.
- Maine — Efficiency Maine Rebates Efficiency Maine administers heat pump rebates with enhanced amounts for income-qualified households. Maine has supported over 200,000 heat pump installs statewide. Pairs with Net Energy Billing (NEB) enrollment for the solar side through CMP or Versant Power.
- Vermont — Efficiency Vermont + GMP Programs Efficiency Vermont provides guidance and contractor connections. Green Mountain Power customers adding battery storage to solar qualify for the BYOD upfront rebate up to $10,500. Net metering base rate of $0.1839/kWh locked for 10 years.
- Connecticut — CT Green Bank + Energize CT CT Green Bank coordinates residential clean energy financing and program access. Cold-climate heat pump installations may qualify for Energize CT incentives alongside the solar tariff structure through Eversource or United Illuminating. Confirm current program eligibility at time of application.
What a Solar + Heat Pump Project Looks Like
Three components, one coordinated installation. Each piece earns its own incentives — and all three are more valuable when designed together than when installed separately.
Cold-Climate Heat Pump
Air-source, ductless mini-split, or central split-system heat pumps sized and specified for New England's climate demands. Manual J load calculation, cold-climate certified equipment, utility rebate documentation, and licensed electrical work included on every install. Whole-home or partial-home configurations depending on your existing heating setup.
Solar Array
Custom-designed solar systems sized to cover both your existing electrical load and the added consumption from the heat pump — typically 2 to 3 kW larger than a solar-only design. Roof or ground mount, state incentive program enrollment, and utility interconnection all handled end-to-end by the same team doing the heat pump work.
Full Electrification
Solar + heat pump + battery storage is the complete New England electrification stack — eliminating oil and propane costs, slashing electricity bills, and building backup resilience for nor'easter season outages. Each component earns its own state incentive. All three installed on one timeline, one permit application, one project manager, one warranty contact.

Solar + Heat Pump FAQ
Yes — and they're specifically designed to complement each other. Solar panels generate electricity; heat pumps run entirely on electricity. Pairing them means the solar array can directly power the heat pump's heating and cooling load, reducing or eliminating the grid electricity your heat pump would otherwise consume. The financial case is stronger when both are designed together rather than added separately years apart.
The key sizing adjustment is planning the solar array 2 to 3 kW larger than a solar-only design to account for the heat pump's added annual electricity consumption — typically 2,000 to 6,000 kWh per year depending on your home's size and climate zone. We model this against your actual utility usage data on every combined quote.
Yes — cold-climate heat pumps are specifically engineered for New England's climate. Modern cold-climate units maintain efficient heating performance at temperatures well below freezing, with many models rated for reliable operation at -13°F or colder. This is a fundamentally different category of equipment from standard heat pumps of a decade ago, which struggled below freezing.
Many New England homeowners install a heat pump as their primary heating system alongside a backup oil or propane furnace for the coldest days of the year — especially in northern Maine, the White Mountains, and Vermont's higher elevations. We design every system with a Manual J load calculation and discuss the hybrid vs. full-replacement option honestly on every quote.
A typical whole-home cold-climate heat pump adds roughly 2,000 to 6,000 kWh of annual electricity consumption depending on home size, climate zone, and insulation quality. To cover that load with solar, you generally need 6 to 12 additional panels beyond what you'd install for a solar-only system — with the typical combined system running 10 to 16 panels total for a New England home.
The exact count depends on your roof's orientation, available square footage, the specific heat pump system spec, and your baseline electricity usage. We size every combined system against your actual utility interval data and heat pump load modeling — not a national average formula. The result is a system sized for your home, not a template.
For most New England homes, yes — particularly homes currently heating with oil or propane. The combination attacks two separate monthly costs simultaneously: electricity bills through solar generation, and heating fuel bills through heat pump electrification. When both systems are coordinated, the solar array is sized to cover the heat pump's added electricity demand, which means the fuel savings aren't partially offset by a higher electric bill.
The stacked state incentive programs across New England — Mass Save in MA, NHSaves in NH, Efficiency Maine, Efficiency Vermont — significantly reduce the upfront investment on the heat pump side, while solar programs like SMART in MA and GMP net metering in VT create ongoing income or bill offsets over the system's life.
Yes — Massachusetts requires a Home Energy Assessment completed through Mass Save before heat pump rebate applications can be processed. The assessment evaluates your home's insulation levels, air sealing, existing heating and cooling equipment, and overall energy performance. It's free for most Massachusetts homeowners through Mass Save, and it often identifies additional weatherization improvements that can be bundled with the heat pump project.
We coordinate the assessment scheduling as part of the project timeline so it doesn't create delays. The assessment results also directly inform the heat pump sizing — a more insulated home needs a smaller system, which reduces the upfront cost and can increase the net rebate percentage. It's a required step that actually improves the project economics.
Adding battery storage completes the electrification stack and adds two specific values beyond backup power. First, in Massachusetts, battery storage unlocks ConnectedSolutions — a demand-response program through Eversource or National Grid that pays annual income for sharing battery power during peak summer grid demand. Second, with heat pumps increasing your electrical load, a battery lets you store midday solar surplus and use it to power the heat pump in the evening instead of drawing from the grid.
In Vermont, Green Mountain Power's BYOD battery rebate program pays up to $10,500 upfront for qualifying battery installations paired with solar — one of the strongest battery incentives in the country. For homes in areas with frequent outages (Lakes Region, White Mountains, rural Maine), the resilience value is also meaningful independently of the financial programs.
