Photovoltaic potential and solar resource maps of Canada

Interactive maps of the photovoltaic (PV) potential and solar resource of Canada have been developed by the Canadian Forest Service (Great Lakes Forestry Centre) in collaboration with the CanmetENERGY Photovoltaic systems group. Insolation data was provided by the Data Analysis and Archive Division, Meteorological Service of Canada, Environment Canada. The maps give estimates of the electricity that can be generated by grid-connected photovoltaic arrays without batteries (in kWh/kW) and of the mean daily global insolation (in MJ/m² and in kWh/m²) for any location in Canada on a 300 arc seconds ~10 km grid. They are presented for each month and for the entire year, for six different PV array orientations: a sun-tracking orientation and five fixed South-facing orientations with latitude, vertical (90°), horizontal (0°) and latitude ± 15° tilts (see figure). Data can be obtained at any grid location by "querying" the maps.

Database of photovoltaic potential and solar resource for Canadian municipalities

Data can also be obtained directly for individual municipalities (over 3500 municipalities are included) by selecting a municipality on the left menu. A search can be performed by entering all or part of the municipality name (a minimum of 3 characters is required in the search string), or by browsing municipalities listed by province, alphabetically.
