Which roof will you put your panels on?
In Canada, the sun travels across the southern sky. The direction your roof faces makes a big difference to how much power you generate.
★★★ Best
South-facing
Full sun from morning to evening. Highest energy output all year. Always the first choice for solar in Canada.
~100% output
★★ Good
East-facing
Strong morning sun, drops off by early afternoon. Good for communities using power early in the day.
~70% output
★★ Good
West-facing
Peaks in the late afternoon, low in the morning. Can match the evening demand peak in many communities.

✗ Avoid
North-facing
Faces away from the sun almost all year. Panels receive very little direct sunlight — not a viable option.
