Cost of Solar Panels Calculator
How to use this calculator
The calculator turns your usage into a kW system size, then prices it at Canadian market rates. Five inputs:
- Monthly electricity use (kWh) — pull from your utility online dashboard. The 2026 NRCan residential average ranges from 380 kWh/month (BC apartment) to 1,400 kWh/month (Alberta detached with electric heat). Heat-pump heated home in Ontario? 800 to 1,200 kWh/month. EV? Add 200 to 350 kWh/month.
- Target offset (%) — 100% means a system sized to match annual usage. Most Canadian provinces have net metering with 1:1 kWh credit (no rate differential), so 100% offset is the right target. Ontario, Alberta, BC have annual true-up; Quebec and Manitoba have monthly carry-forward; Nova Scotia has 12-month bank.
- Peak sun hours/day — Canadian annual averages from CanmetENERGY: Toronto 3.7, Calgary 4.5, Edmonton 4.3, Vancouver 3.0, Montreal 3.7, Ottawa 4.0, Halifax 3.6, Winnipeg 4.3, Regina 4.5, Whitehorse 3.2, Yellowknife 3.5. Note: winter production is roughly 30% of summer in southern Canada, so the annual average is what matters for system sizing.
- Installed cost per watt — the all-in turnkey price including labour, equipment, ESA/AHJ permits, and utility interconnection. The 2026 CanREA-tracked median is C$3.20/W for 5 to 10 kW systems. Use your actual quote.
- Federal/provincial rebate (%) — 0 if you have no provincial rebate. PEI residents: enter ~25% (C$1.00/W on $3.20/W base = 31%, capped at C$10,000). NS residents: enter ~9% (C$0.30/W on $3.20/W = 9%, capped at C$3,000). Combine with Greener Homes Loan (0% interest, not a rebate but reduces effective cost).
How the math works
annual_target_kWh = monthly_kWh × 12 × (offset% / 100)
system_kW = annual_target_kWh / (peak_sun_hours × 365 × 0.78)
gross_cost = system_kW × 1000 × C$/W
net_cost = gross_cost × (1 - rebate% / 100)
range_low/high = gross_cost × 0.85 / 1.15
Worked example for a Toronto home using 950 kWh/month:
- Annual target: 950 × 12 × 1.0 = 11,400 kWh
- System size: 11,400 / (3.7 × 365 × 0.78) = 10.81 kW
- Gross cost at C$3.20/W: 10,810 × C$3.20 = C$34,592
- Typical range: C$29,403 to C$39,781
- With Greener Homes Loan (0%, 10-year): C$288/month, offset by ~C$120/month bill savings

What is and is not included in C$/W
A typical C$3.20/W turnkey quote includes:
- Tier-1 panels CSA-certified (Canadian Solar, Heliene, Silfab — all manufactured in North America)
- Inverter CSA-listed (Enphase, SolarEdge, Fronius, SMA)
- CSA C22.1 (Canadian Electrical Code) compliant wiring and grounding
- Snow-load-rated racking (IronRidge XR, S-5! for metal roof) per NBC 2020
- ESA permit (Ontario), RBQ permit (Quebec), or local AHJ permit
- Utility interconnection application (form varies — Hydro One, BC Hydro, Hydro-Québec, etc.)
- Rapid shutdown compliance per CSA C22.2 No. 330
- 25-year panel warranty, 12 to 25-year inverter warranty
- 5-year workmanship warranty (CanREA member standard)
What it does not include:
- Service upgrade to 200A from 100A — C$2,500 to C$5,000 (very common in pre-1990 homes)
- Critical-loads sub-panel for battery backup — C$1,500 to C$3,500
- Snow-shedding tiles or dam removal — C$300 to C$1,500 (more common in QC, NB, NS)
- Tree removal for shading — C$500 to C$3,000
- Battery storage — C$15,000 to C$22,000 for 13.5 kWh Tesla Powerwall 3 installed
- EV charger if added concurrently — C$1,200 to C$2,500
Net metering by province (2026)
All Canadian provinces have some form of net metering, but the rules vary substantially:
- Ontario — IESO net metering, monthly carry-forward, 12-month true-up, no expiry of credits
- Quebec — Hydro-Québec self-generation, monthly bank, no payout for surplus at year-end
- BC — BC Hydro net metering, monthly bank, March 1 annual settlement at 9.99c/kWh
- Alberta — Distribution-Connected Generation, monthly bank, settlement at energy-only rate
- Saskatchewan — SaskPower NMP, monthly bank
- Nova Scotia — Enhanced Net Metering, 12-month rolling, settlement at retail rate to 100% offset
- New Brunswick — NB Power Total Energy, monthly bank, settlement at retail rate
- PEI — Maritime Electric Net Metering, monthly bank
- Newfoundland — Net Metering Service, monthly bank to NL Hydro
Net metering with 1:1 retail-rate credit is critical to Canadian solar economics — without it, payback would extend by 4 to 6 years given the relatively low retail rates.
Pair this with the payback calculator, ROI calculator, and savings calculator
Cost gives you the up-front outlay; payback tells you when you break even (typically 12 to 18 years in Canada due to lower retail rates); ROI gives you the lifetime return; savings shows you the year-over-year cash flow with provincial net metering.
