Solar in Quebec
What a typical 7 kW rooftop system generates and saves in Quebec, from NRCan sun data and the local power rate. A planning estimate, not a quote.
Based on 1185 kWh per kW per year of sun in Quebec, a 7.8¢ per kWh rate, and $2.90 per watt installed.
In Quebec, the payback is on the long side. Quebec has good sun but the cheapest electricity in Canada, so solar saves the least here in dollar terms: the payback is the longest in the country.
