Solar Energy Map Canada

National Average Solar Energy Production Potential: 1133 kWh/kW/yr

This page contains solar energy maps, along with monthly solar production estimates, for every province and territory in Canada.

Solar energy maps show the amount of energy that a solar photovoltaic system can produce (in units of kWh/kW/yr), based on the intensity of light that reaches the Earth’s surface.

How to use Solar Energy Maps

Solar Power Maps Canada Scale

Solar maps can be used to answer two key questions:

  • Question 1: “How much energy (in units of kWh) can a solar power system (in units of kW) produce per year (yr) in my region?”

Answering this question is easy – simply look at the value on the map or find your city below!

  • Question 2: “What size of solar system will I need to install (kW) to offset my annual (yr) electricity usage (kWh)?”

You can easily calculate the size of the system that you would need to offset your annual electricity usage, as well as your total system costs, by visiting our Solar Cost of Solar page.


Solar Production Potential by Province

Solar Energy Production Potential Canada

We’ve gone ahead and calculated the average solar production potential based on the five most populated cities for every province and territory in Canada. 

This capacity to turn light into electricity is also a major ranking factor in our Provincial Solar Rankings.

Here is the annual average equivalent of full sunlight hours broken down by province:

Canada’s Best and Worst for Solar Energy

  • The best provinces for producing solar energy in Canada are all located on the prairies: Alberta, Manitoba, and Saskatchewan.

This is because these provinces have relatively sunny weather all year around.

  • The worst province for producing solar energy in Canada Newfoundland and Labrador, while the worst territory is the Yukon.

This is primarily because of high annual cloud cover in Newfoundland and Labrador, and a combination of high latitude (shorter summer days) and cloudy weather in the Yukon.

  • The best place in Canada for producing solar power is Torquay, Saskatchewan (which has a solar energy potential of 1384 kWh/kW/yr), while the worst place is at the small research base located in Eureka, Nunavut (780 kWh/kW/yr).
  • The best month for producing solar energy in Canada is April when days are mid-length and skies are clear. The worst month for producing solar energy in Canada is December when days are short.

Methodology and External References

Solar production potential was calculated using the “mean daily global insolation (kWh/m2 or full sun hours (h))” in Natural Resource Canada’s photovoltaic potential and insolation dataset spreadsheet (“municip_kWh”).

  • We used values for a south-facing tilt where the installation angle equals degree latitude -15°.
  • A 25% efficiency loss factor was then applied before getting the final kWh/kW/yr number.
  • The top five populated cities from each province were used to calculate province and territorial averages.

While the data presented on this page is accurate to three digits, the maps here are intended to be illustrative representations rather than a precise geographic information system.

NRCan has an ArcGIS web mapping application which can be used to lookup data for any municipality in Canada, and an additional list of solar resource data sources here.
