Apples & Oranges—But Often Eaten Together
I hear the debate weekly: “Should I choose solar panels or a heat pump?” Truth is, solar panels vs heat pumps isn’t a direct either-or. One makes electricity, the other uses it ultra-efficiently. Let’s see why this usually ends with “get both—eventually,” and which upgrade should land first on your budget list.
How Each Tech Slashes Bills
Factor | Solar panels | Heat pumps |
Primary job | Generate power | Move heat in/out |
Bill impact | Whole-home kWh (12 mo) | Heating + cooling only |
Lifespan | 25–30 yrs (≤ 0.4 %/yr loss) | 12–15 yrs before replacement |
Incentives | 0 % Greener Homes loan (up to $40 000) | Greener Homes + Oil-to-Heat-Pump grants (up to $5 600) |
Because solar touches every appliance—lights, fridge, EV charger—it often wins the headline solar panels vs heat pumps savings race.
Net-Metering—Your Silent “Battery”
Nova Scotia Power credits surplus solar kWh at a one-for-one retail rate, banking summer sunshine for winter nights. That virtual storage boosts the payback, since panels feed your pump with effectively free energy.
ROI Snapshot—Which Upgrade First?
Upgrade path | Year-1 cash flow* | Payback | Why/When |
Solar first (7 kW) | – $25 000 (0 % loan) | 8–10 yrs | Cuts whole bill; fuels future pump |
Heat pump first (ductless, 18 000 BTU) | – $7 000 (after grant) | 6–8 yrs | If oil furnace costs > $2.00/L |
Both together | – $32 000 | 10–12 yrs | Ultimate carbon & cost drop |
*Typical suburban load. Individual results vary.
Why Pairing Beats Picking
Mention solar panels vs heat pumps a third time: run the pump on sunshine and you displace pricey grid kWh and heating oil—stacked savings with a single emission punch.
- Summer: Solar powers A/C mode outright.
- Shoulder seasons: Excess solar tops up annual kWh bank.
- Winter: Banked credits offset pump’s heating draw.
Real-World Case—Wolfville Bungalow
A retired couple installed 6 kW of JA Solar JAM54D41-440/LB modules in 2022, then added a cold-climate mini-split in 2024. Solar now covers 80 % of their total load—including the pump—and their annual NSP bill fell from $2 300 to under $500.

Start Smart—Decision Checklist
- Fuel type: Still burning oil? Tackle the heat pump grant while it lasts.
- Roof sun hours: South-facing? Lean solar first.
- Cash flow: 0 % solar loan bigger than heat-pump grant; choose what fits.
