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) The 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.
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.
The South of the Canadian prairies have a huge solar potential.
The highest solar hotspots have energy level at par with Arizona or California, when the temperature effect on the PV efficiency is considered.
The second lowest point (Sandspit on Haida Gwaii) has still comparable solar energy than most places in Germany.
