How this Mississauga solar cost calculator works
This calculator sizes a solar system from your electricity use. Your monthly bill, divided by the average Ontario electricity price, gives your yearly use; Ontario's sunshine (1,170 kWh per kW of panels a year) then gives the system size that covers it, adjusted for roof direction and shade. The installed price is that size multiplied by the price per watt homeowners in Ontario pay installers. Payback compares that price with what the panels save at Ontario power prices, assuming prices rise 3% a year.
Ontario numbers this calculator uses
- Installed price
- $2.42–$3.05 per watt in Ontario (CAD) (typical $2.74), before rebates. A typical 6 kW home system costs $14,500–$18,300.
- Sunshine
- 1,170 kWh of electricity per kW of panels a year in Ontario.
- Electricity price
- About 15¢ per kWh, the average residential price in Ontario.
- Selling power back
- Ontario net metering credits exported power for the energy portion of your bill only, not delivery, and credits expire after 12 months.
- Rebates and tax credits
- The Home Renovation Savings Program pays $1,000 per kW, up to $5,000 or half the cost, for systems that power your home without net metering. Battery rebates are also available. There is no federal solar grant or loan open to homeowners in 2026: the Canada Greener Homes Grant closed to new applicants in 2024 and the Greener Homes Loan closed on October 1, 2025.
An estimate, not a quote. Roof size and pitch, shading, equipment, permits and the installer all change the final price; installers confirm it after a site visit.
