Formule
Estimates the solar system size that fits your roof, then multiplies by your provincial peak sun hours to calculate annual electricity generation. The payback period is the net installation cost (after grants) divided by annual electricity bill savings.
Questions Frequentes
How long does it take for solar panels to pay for themselves in Canada?
The payback period varies by province. In Ontario at 10.3c/kWh, a 10 kW system ($28,000 installed) with net metering pays back in approximately 12 to 15 years. In Nova Scotia at 15.5c/kWh, payback is 9 to 12 years. In Quebec at 7.5c/kWh, payback extends to 18 to 22 years because electricity is already cheap. The Greener Homes Grant of up to $5,000 reduces payback by 1 to 3 years.
How much do solar panels produce in Canada?
A 10 kW system in southern Ontario produces approximately 11,500 kWh per year. In Calgary, the same system produces about 13,500 kWh per year due to higher solar irradiance and clear skies. In Vancouver, production is lower at approximately 10,500 kWh per year due to cloud cover. Production is highest from April to September and lowest in December and January.
Is net metering available across Canada?
Net metering is available in most provinces but rules differ. Ontario allows systems up to 500 kW with annual true-up. Alberta allows micro-generation up to 5 MW with monthly credits. BC allows net metering with annual credit carry-forward. Quebec offers net metering but low electricity rates reduce the financial benefit. Saskatchewan and Nova Scotia also offer net metering programs.
What rebates are available for solar panels in Canada?
The federal Greener Homes Grant provides up to $5,000 for solar panel installation. Some provinces offer additional incentives: Alberta has municipal programs in Edmonton and Calgary, Nova Scotia offers the Solar Homes program, and some utilities offer production-based incentives. Combined rebates can offset 15% to 25% of total installation cost.
Do solar panels work in Canadian winters?
Yes, but production drops significantly. A system that produces 1,500 kWh in July may produce only 300 to 500 kWh in December. Cold temperatures actually improve panel efficiency, but shorter days and snow cover reduce output. Snow typically slides off panels within 1 to 2 days on angled roof installations. Annual production calculations already account for seasonal variation.
What is the 25-year savings from solar in Ontario?
A 10 kW system in Ontario producing 11,500 kWh per year saves approximately $1,185 in year one at 10.3c/kWh. Assuming 2% annual electricity price increases and 0.5% panel degradation, cumulative 25-year savings total approximately $38,000 to $45,000. After subtracting the $28,000 installation cost and adding the $5,000 Greener Homes rebate, net profit over 25 years is $15,000 to $22,000.
Which Canadian province is best for solar panels?
Southern Alberta and Saskatchewan have the highest solar irradiance in Canada (4.8 to 5.0 kWh/m2/day), producing the most electricity per panel. However, Nova Scotia offers the best financial return because its high electricity rate (15.5c/kWh) means each kWh generated saves more money. Ontario offers a good balance of solar resource and electricity rates.
