How much solar potential does your roof have?
Explore solar energy potential anywhere in Canada, based on official Government of Canada solar-resource data (Natural Resources Canada & Environment and Climate Change Canada) — over 3,500 locations from coast to coast to coast.
Best provinces for solar in Canada
Average annual photovoltaic potential by province/territory, for a south-facing rooftop system tilted at latitude angle — the standard reference orientation.
Saskatchewan has Canada's highest average solar potential at 1,326 kWh/kWp/year; Newfoundland and Labrador has the lowest at 947.
Canada's sunniest — and cloudiest — places for solar
Ranked by annual photovoltaic potential (kWh generated per kW of installed panels per year) across 3,506 Canadian communities.
Regway, Saskatchewan tops the list at 1,387 kWh/kWp/year; Laxgalts'ap, British Columbia is lowest at 838.

About this data
Last updated: 2026-09-21
Where these numbers come from, and what they do (and don't) tell you.
Values shown are the photovoltaic potential (kWh generated annually per kW of installed panel capacity) for a fixed, south-facing system tilted at latitude angle — the standard reference case — sourced from Natural Resources Canada and Environment and Climate Change Canada's Photovoltaic Potential and Solar Resource Maps of Canada. It's a location-level estimate of the solar resource available, not a rooftop-by-rooftop survey: your actual output depends on your roof's exact orientation, tilt, shading from trees or nearby buildings, panel efficiency, and system design. Think of it as a strong starting point — a solar installer can turn it into an exact quote for your home.

How much solar potential does my roof have in Canada?
It depends on location — the national average is 1,166 kWh/kWp/year, ranging from about 780 in cloudy coastal areas of British Columbia to nearly 1,390 in the sunniest southern Saskatchewan communities. Enter your address above for a site-specific estimate.
What is the average solar potential by province?
Saskatchewan has the highest average at 1,326 kWh/kWp/year, followed by the other Prairie provinces. Newfoundland and Labrador has the lowest average at 947. See the full province-by-province breakdown above.
Which Canadian cities get the most sun for solar panels?
Regway, Saskatchewan and other southern Saskatchewan communities near the US border have Canada's highest photovoltaic potential, at up to 1,387 kWh/kWp/year.
Does cloudy weather mean solar isn't worth it?
Not necessarily. Even Canada's cloudiest regions, like coastal BC, still generate meaningful solar output — 838–900 kWh/kWp/year in the lowest areas — and system cost, local electricity rates, and available rebates often matter as much as raw sun exposure to whether solar pays off.
How is photovoltaic potential calculated?
These figures come from Natural Resources Canada and Environment and Climate Change Canada's official Photovoltaic Potential and Solar Resource Maps of Canada, based on a ~2 km resolution model of solar irradiance, for a fixed, south-facing system tilted at latitude angle — the standard reference case.
