Solar Maps of Canada (P95)


Solar energy yield of optimized solar system in Canada with a P95 exceedance probability

Notes:

  • Three mounting options: Fixed, Vertical Axis Tracker (VAT)  and  2-axis (full) trackers.
  • Arrays inclination optimized for maximum energy yield  at each  location ( fixed and VAT system only)
  • PV  efficiency is  corrected with temperature and low irradiation losses.
  • Based on 30+ years of solar data from 235 federal weather stations.
  • 95% probability of exceedance (P95).   i.e. there is 95% probability that the average solar energy yield over 25 years (the lifetime of the project) will exceed the level indicated on the map .

Canada Solar Energy by Monitoring Station

The solar energy map is calculated on data from 235 weather stations across Canada, provided by Environment Canada.
The chart ranks these stations by energy level. It shows the annual energy yield in kWh/a of a 1 kWp system installed on a full-tracker. The units are in kWh/kWp/a or hr/a. (Note: the chart is very large you will need to zoom to view it)
panmaxbarchartThe highest ‘hot-spot’ is Pincher Creek in West-Alberta with 2,528 hr/a, the lowest ‘cool-spot’ is Prince Rupert on the BC west coast, with 1,290 hr/a.

Findings

  1. Pincher Creek, the hottest spot in Canada  is close to Kimberley where EcoSmart is helping develop SunMine, the first large scale solar project in BC.
  2. The South of the Canadian prairies have a huge solar potential.
  3. The highest solar hotspots have energy level at par with Arizona or California,   when the temperature effect on the PV efficiency is considered.
  4. The second lowest point (Sandspit on Haida Gwaii) has still comparable solar energy than most places in Germany.
