- round 7,200 kWh/year (lower due to gas heating).
- Ontario or BC: Closer to 10,000-15,000 kWh if you have electric heat or an EV.
Track your bills or use an online calculator to get your exact number.
Step 2: Calculate System Size
To cover most of your needs, aim for a 6-10 kW solar system for an average home.magsolar.ca Here’s a quick math:
- Annual use: 11,000 kWh.
- Average peak sun hours in Canada: 3-5 per day (more in prairies, less in north).
- Using 4 hours: You’d need about 7.5 kW (or 18-25 panels at 400W each).solar.com
For a bigger home or high use, go up to 10-15 kW. Factor in snow cover or shade—panels work in cold, but sunlight matters most.
Step 3: Consider Canadian Factors
- Sunlight by Province: Southern Ontario gets 4-5 hours daily; Yukon, maybe 2-3. Use tools like PVWatts for your spot.
- Roof Space: Need at least 335 square feet for a standard setup.cdnsolar.ca
- Costs: Average install is $2.50-$3.50 per watt after incentives. A 7 kW system? Around $15,000-$20,000 out of pocket.solarreviews.com
