Solar savings calculatorWhat could solar
save you?
Estimate the system size and yearly savings for your home in about 30 seconds, using Natural Resources Canada solar data and 2025 electricity prices for your province.
About $0 over 25 years at today's prices
Extra summer power is credited through net metering and offsets the darker months.
Estimate only, based on provincial averages. How we calculate it
Real data, plain assumptions.
- Solar productionNatural Resources Canada's photovoltaic potential data, averaged by province, adjusted for the direction your roof faces and how shaded it is.
- Electricity pricesHydro-Québec's 2025 comparison of electricity bills in major Canadian cities, with rates in effect April 1, 2025, before taxes. We use the cost of each additional kilowatt-hour, because solar doesn't reduce fixed monthly charges.
- Your usageEstimated from your bill using typical bills in your province, or taken directly from the kWh you enter.
- 25-year savingsToday's prices, with panels losing about 0.6% of their output a year, the rate Natural Resources Canada uses for well-functioning systems.
- Not includedSystem price, incentives, taxes and your utility's specific net-metering rules. Your proposal covers all of these.

How accurate is this estimate?
It's a starting point based on provincial averages. Your actual production depends on your roof's exact angle, direction and shading, and your savings depend on your utility's rates and net-metering rules. A free assessment gives you exact numbers for your home.
Why does my province make such a difference?
Two reasons: how much sun your region gets, and what you pay for electricity. The Prairies get the most sun in Canada, and provinces with higher electricity prices save more for every kilowatt-hour your panels produce.
Does the estimate include the system price or incentives?
No. System prices depend on your roof and the equipment chosen, and incentive programs vary by province and change often. Your proposal includes a fixed price, the incentives available to you and your payback period.
