What a solar costs in Toronto

Rebates: our verified program data, checked monthly. Always confirm the exact amount for your home.

How much sun does Toronto get?

Toronto averages about 3.9 peak sun hours a day, more than 41% of the 123 cities we track. As a rough guide, each kilowatt of panels here makes about 1,140 kWh a year (after typical system losses). A good installer will give you a roof-specific estimate that accounts for shading and roof angle.

Source: Open-Meteo historical solar radiation, 2020-2024. Production estimate assumes 80% system efficiency.

Before you hire a solar installer

1. Ask for a production estimate for your roof (kWh per year) and how shading was measured.
2. Ask which panels and inverter they use, and who backs the warranty if the company closes.
3. Ask how your utility credits extra power you send to the grid, and whether a battery makes sense for you.

Before you call anyone, check what solar rebates you can get in Toronto. Many programs require approval or a registered contractor before work starts.
