The solar potential for Canadian regions identifies the areas that are most suitable for solar renewable developments, according to the intensity and amount of solar energy the region experiences.
Natural Resources Canada has a list of Canadian municipalities and their solar photovoltaic potential: download the photovoltaic and solar resource maps. The spreadsheets have estimates for the potential of electricity generated and the average daily insolation (ie. the amount of solar radiation that impacts that location).
Natural Resources Canada also collects historical and current datasets from sources around the world that relate to solar radiation and photovoltaic potential: see all solar resource datasets from Natural Resources Canada.
