Solar energy potential in Canada, Yes really!
The solar energy potential for an area helps to determine the amount of energy a PV system can generate. The greater the amount of sunlight or irradiance in an area the lower the cost of energy.
Solar energy potential is measured in kilowatt hours (kWh) generated per kilowatt (kW) of PV installed. The image below of Western Canada shows the potential annual electricity generation from PV. It can range from approximately 800 to 1400 kWh/kW.

The chart provides estimates of the electricity that can be generated by grid connected PV arrays. The performance ratio quantifies and takes into account overall system losses due to operation under non-ideal conditions: climatic factors, inverter operation and so on.
When designing a system we request a year’s worth of electrical utility bills from the client to determine how much energy is needed each year. We then design a system to meet this demand.
Thus, a residential home in Edmonton that uses approximately 6,000 kWh per year of electricity, would require a 5kW system to produce the necessary energy (~6,225 ) each year.
(5kW x 1245 kW h/kW = 6,225KWh )
The table below lists several municipal rankings in terms of yearly PV potential (for South-facing PV panels with latitude tilt).
