## Frequently Asked Questions

**How much do solar panels cost in Canada?**
Installed residential solar in Canada typically costs about $2.40 to $3.30 per watt before incentives, roughly $19,000 to $26,000 for an 8 kW system. There is no federal tax credit for homeowners. Provincial programs such as Ontario's Home Renovation Savings rebate (up to $5,000 for solar) can reduce the net cost.

**What is the payback period for solar in Canada?**
7–18 years depending on province. Alberta and Ontario are fastest (8–10 years) due to higher electricity rates and strong incentives. Quebec is longest (18 years) due to very low hydro rates.

**Do solar panels work in Canadian winters?**
Yes. Panels operate more efficiently in cold temperatures. Winter production is 30–50% of summer, but annual calculations account for this. Snow typically slides off within 1–2 days.

**What solar incentives are available in Canada in 2026?**
Federal: no tax credit for homeowners. The Clean Technology Investment Tax Credit is limited to corporations, and the Canada Greener Homes Grant and Loan are closed. Provincial: Ontario Home Renovation Savings pays $1,000 per kW of solar up to $5,000 and $300 per kWh of battery storage up to $5,000, each capped at 50 percent of cost. Alberta municipalities offer CEIP financing, and other provinces run their own programs.

**Is net metering available in all provinces?**
Most provinces offer net metering. Ontario offers net metering under O. Reg. 541/05. Ontario homeowners who take the Home Renovation Savings rebate must instead use a load displacement design and cannot sign a net metering agreement. Alberta, BC, Saskatchewan, Quebec and the Atlantic provinces have their own net metering or micro generation programs.

## Calculation Methodology

The Solar Calculator Canada platform uses the following methodology to produce accurate solar estimates:

- **Solar irradiance data**: Uses NRCan (Natural Resources Canada) and PVGIS (Photovoltaic Geographical Information System) solar irradiance datasets calibrated to Canadian locations
- **Panel degradation**: Models 0.5% per year degradation over a 25-year system lifespan
- **Temperature derating**: Applies location-specific temperature coefficients to adjust panel output based on ambient conditions — panels perform better in cold Canadian climates but lose efficiency during summer heat
- **Snow loss factors**: Incorporates snow coverage estimates for Canadian climate zones, accounting for reduced production during winter months and snow clearing timelines
- **Net metering credit calculations**: Varies by province — some provinces credit at full retail rate (Alberta), others at reduced export rates (Saskatchewan at 7.5¢/kWh), and Ontario offers both net metering and a load displacement path under the HRS rebate
- **Peak shaving modeling**: Uses Time-of-Use (TOU) and Ultra-Low Overnight (ULO) rate arbitrage to calculate battery storage savings, optimizing charge/discharge cycles around rate periods
- **Battery sizing**: Based on household consumption patterns, peak demand profiles, and rate structure to recommend optimal battery capacity
- **Financial modeling**: Includes electricity rate escalation assumptions of 3-5% per year, federal and provincial incentive calculations, and 25-year cash flow projections with NPV and IRR analysis

## Data Sources

- **Natural Resources Canada (NRCan)** — solar irradiance maps and photovoltaic potential data for all Canadian locations
- **PVGIS European Commission** — photovoltaic performance data and solar radiation databases
- **NREL PVWatts** — production modeling and system performance calculations
- **Provincial utility rate schedules** — updated quarterly from official utility publications (Hydro One, Toronto Hydro, BC Hydro, ENMAX, EPCOR, SaskPower, Hydro-Quebec, and others)
- **Federal/provincial government incentive databases** — Clean Technology ITC (business only), Ontario HRS, Alberta CEIP, CleanBC, and all provincial rebate programs
