What is grid parity? Click to learn.
Grid parity, also called socket parity, is a measurement that compares the cost of solar electricity with the cost of residential retail electricity. When grid parity is reached, it starts to become more economical for you to install solar panels on your roof rather than purchasing power from your utility company. Read more here.

Analysis assumptions:
  • Province or territory average values are determined using the relevant values for capitals.
  • Solar generation figures are based on an average-sized residential solar PV system of 5 kW.
  • Default installation cost is estimated to be $3.5/watt (in Canadian dollars).
  • Annual solar production estimates (for levelized cost calculations) are based on our own solar energy calculator, Sunmetrix Discover.
  • Utility rates for the provinces are based on a study published by Hydro Quebec. Rates in effect in April 2016. Source: Comparison of Electricity Prices in Major North American Cities. Utility rates for the territories are based on residential rate data as reported by Qulliq Energy Corporation (as displayed on 27 September 2016); Northwest Territories Power Corporation (effective 1 September 2016); Yukon Housing Corporation (effective 1 May 2016).
  • Homeowners who qualify for Ontario's feed-in tariff program can potentially get higher rates of return for their solar PV investments. For more information on the microFIT program, click here.
