Solar vs Grid Electricity Cost — 2026 Canada Comparison
Side-by-side cost comparison of rooftop solar against Canadian grid electricity in 2026. Levelised cost per kWh, payback period, provincial tariffs, and Greener Homes Loan economics.
The Canadian solar-vs-grid comparison is the most province-dependent of any market — federal incentives are uniform but provincial retail electricity tariffs span more than a 4× range. A Quebec resident on Hydro-Québec’s Rate D pays C$0.078/kWh for the first 40 kWh/day; an Alberta resident on a typical Direct Energy Regulated Service plan pays C$0.18–C$0.24/kWh depending on month. A 7 kW residential system installed under CSA C22.1-compliant guidelines lands at a 25-year LCOE of roughly C$0.09–C$0.13 per kWh post-Greener Homes Loan financing. The case for solar is strong in Alberta, Ontario, Saskatchewan, BC and the Maritimes — and notably weak in Quebec and Manitoba where regulated hydro keeps the grid rate below most LCOE benchmarks.
Levelised cost: solar vs grid
For a 7 kW system in Ontario (5.0 PSH after snow):
- Gross cost: C$22,400 (NRCan 2026 Survey of Household Energy Use-aligned median)
- Federal Greener Homes Grant closed Feb 2024; Greener Homes Loan 0% APR 10-yr remains for up to C$40,000 — this changes the financing model but not the LCOE
- 25-year production: ~204,000 kWh (CanmetENERGY snow-loss factor 0.76 derate, 0.5%/yr degradation)
- O&M + 1 inverter replacement (year 12): C$3,000
- LCOE: C$0.124/kWh
Compare to Toronto Hydro residential time-of-use January 2026: off-peak C$0.087, mid-peak C$0.122, on-peak C$0.187. Solar LCOE matches mid-peak rate and beats on-peak by ~30%.
Province-by-province comparison (Q1 2026)
| Province | Residential rate (C¢/kWh) | Solar LCOE | Net-metering regime | Verdict |
|---|---|---|---|---|
| Alberta | 18–24 (deregulated) | 11 | Net-billing; PPAs | Solar wins decisively |
| BC (BC Hydro) | 11–15 (Step 1/Step 2) | 11 | Net-metering | Solar wins on Step 2 |
| Saskatchewan | 17 | 11 | Net-metering 7-yr | Solar wins |
| Manitoba | 10 | 11 | Net-metering | Grid wins narrowly |
| Ontario | 8.7–18.7 ULO | 12 | Net-metering | Solar wins on mid/on-peak |
| Quebec | 7.8 (D rate) | 12 | Net-metering banking | Grid wins |
| New Brunswick | 13.5 | 12 | Net-metering 1:1 | Solar wins narrowly |
| Nova Scotia | 17 | 12 | Net-metering | Solar wins (with SolarHomes) |
| PEI | 17 | 11 | Net-metering | Solar wins (with rebate) |
| Newfoundland | 14 | 12 | Net-metering | Solar wins narrowly |
| Yukon (Whitehorse) | 16 | 14 | Net-metering | Solar competitive |
| NWT (Yellowknife) | 30 | 16 | Net-metering | Solar wins despite low yield |
| Nunavut | 60+ | 18 | Limited; subsidised | Solar wins on diesel offset |

Greener Homes Loan: 0% APR changes the cash math
Even though the Greener Homes Loan does not reduce LCOE, it changes the homeowner’s monthly cash position dramatically. Example: 7 kW system at C$22,400, 10-year term, 0% APR:
- Monthly loan payment: C$187
- Monthly bill savings (Toronto Hydro TOU, ~7,000 kWh/yr offset): ~C$110
- Net monthly cost during loan: −C$77 (out of pocket)
- After year 10: pure C$1,300/year savings, escalating
Buyers in Quebec and Manitoba where bill savings are below C$80/month will see negative monthly cash flow throughout the loan term. Buyers in Ontario, BC (Step 2), Saskatchewan, NS and PEI typically see positive monthly cash flow within years 4–6.
Provincial incentive stack (April 2026)
- Federal: Greener Homes Loan 0% APR up to C$40,000 over 10 years.
- PEI: SolarHomes rebate C$1.00/W up to C$10,000.
- Nova Scotia: SolarHomes Performance-Based rebate C$0.30/W up to 10 kW (~C$3,000 typical).
- Yukon: Good Energy rebate up to C$5,000.
- NWT: Arctic Energy Alliance rebate up to C$20,000 (community-tier).
- Quebec: Rénoclimat C$0.45/W (limited; D rate cap heavily depresses solar economics regardless).
- NB: Total Home Energy Savings Program C$0.20/W up to C$10,000.
- NL: takeCHARGE rebate up to C$5,000.
- AB / SK / BC / ON / MB: no provincial cash rebate; net-metering is the primary lever.
Cold climate de-rating: the real production hit
CanmetENERGY’s PVPMC ground-truth data shows annual production losses of 18–28% versus the U.S. PVWatts continental baseline:
- Snow cover: 5–15% annual loss (varies with tilt; 35° pitch sheds well, 15° flat-mount accumulates).
- Cold-weather inverter clipping: 2–4% on cold-clear winter days when DC voltage briefly exceeds inverter Vmp.
- Reduced winter daylight hours: 30–40% annual production gap between June and December.
The flip side: panels operate at 0.4%/°C above their rating in cold weather, so May to October production in southern Ontario, BC and Quebec routinely exceeds their U.S. counterparts.
The 30-second answer
Solar in 2026 beats the grid on a 25-year LCOE basis in every Canadian province except Quebec and Manitoba, where regulated hydro tariffs below C$0.10/kWh keep the grid the cheaper energy source. The Greener Homes Loan at 0% APR makes solar accessible without out-of-pocket capital, but does not change the underlying LCOE math. Best-case markets (highest spread, fastest payback): Alberta (deregulated retail), Ontario on TOU, BC on Step 2, Nova Scotia and PEI with provincial rebates, and any northern community on diesel-displacement economics.
