Heat pump cuts heating bills 25–45%. Solar + battery adds outage resilience and grid independence, but costs $25K–$40K more upfront. Here's the real math on which combo makes sense for your home.
Start with insulation + heat pump ($8K–$14K net after rebates). That's your biggest payback in years 1–5. Add solar + battery only if: (1) you want outage backup, (2) you live on time-of-use electricity rates, or (3) you're building net-zero as a long-term lifestyle choice. Heat pump alone is the financially smart first move.
Installed: $13,000–$16,000
CleanBC rebate: $4,000–$16,000 (income-qualified)
Your net (middle income): $3,000–$8,000
Annual heating savings: $1,200–$2,000 vs gas furnace
Payback: 2–4 years
System cost: $13,000 (HP) + $28,000 (solar) = $41,000
Combined rebates: $10,000 (heat pump) + $5,000 (solar) = $15,000
Your net: $26,000
Annual combined savings: $2,200–$3,200 (heating + electricity generation)
Payback: 8–12 years
System cost: $13,000 + $28,000 + $15,000 = $56,000
Combined rebates: $10,000 + $5,000 + $3,000 = $18,000
Your net: $38,000
Annual savings: $2,500–$3,500 (heating + solar + Peak Saver bonus)
Payback: 11–16 years
Mild winters mean heat pump ROI is slower (25–30% savings vs gas). Solar payback is 13–16 years. Battery makes sense only if you value outage backup (storm season is real on the coast).
Recommendation: Heat pump + insulation first. Solar is optional, battery even more so unless you're in a flood zone.
Colder winters (4,700–5,200 heating degree days) = higher heating savings. Heat pump payback drops to 2–3 years. Solar is decent (3.8–4.0 sun hours/day). Battery makes more sense here because Peak Saver enrollment pays $500 + $250/season bonus on top of avoiding grid peak pricing.
Recommendation: Heat pump first (fastest payback). Solar is worth considering. Battery if you want the Peak Saver rebate stream.
Extreme winters (6,100+ heating degree days) mean massive heating savings (40–45%). Heat pump payback is fastest in BC (1.5–2.5 years). Solar is lower potential (2.9–3.0 sun hours/day), but battery for outage resilience during winter storms is genuinely valuable.
Recommendation: Heat pump absolutely. Solar only if you have south-facing roof. Battery yes—outages are real in winter.
Heat pumps cut heating bills year-round, immediately. A 5-ton system handles 80–90% of your heating needs, even in Prince George winters. You see the savings from month one.
Solar generates power only during daylight (less relevant in winter when you need heat most). Battery sits idle most days unless you're on time-of-use rates or experience frequent outages.
Financially: heat pump payback is 2–4 years. Solar is 11–16 years. Battery pushes it to 15+ years. The math is clear.

Don't use Tesla Powerwall in BC. It's not on BC Hydro's approved battery list, so you get zero rebate ($0 instead of $3,000–$5,000). Eguana Evolve, LG Chem, and Sonnen are all approved and cheaper anyway. Not worth it.
| Priority | Install | Payback | Do it when? |
|---|---|---|---|
| 1 | Insulation + air sealing | 3–5 years | First. Makes heat pump 30% smaller and cheaper. |
| 2 | Heat pump | 2–4 years | Second. Biggest ROI. Do it in year 1. |
| 3 | Solar panels | 11–16 years | Year 3+. Only if heating is solved. |
| 4 | Battery storage | 15+ years (economic), priceless (resilience) | Year 5+. Or skip entirely if you're budget-conscious. |
Heat pump alone saves more money faster. Solar + battery feel aspirational and offer genuine resilience value, but they don't pencil out financially until year 10+.
If you've got $15K, spend it on insulation + heat pump. If you've got $40K, do insulation + heat pump + solar. If you've got $50K+ and you value outages prevention more than ROI, add the battery.
Don't let perfect (net-zero house with backup power) be the enemy of good (heat pump that cuts your heating bills by 30% in year one).
