Is Solar Worth It in Ontario in 2026?

What drives the verdict in Ontario
Your rate matters more than your sun. Ontario averages C$0.152/kWh and 3.7 peak sun hours. Canada's cheapest electricity (Quebec) makes solar a lifestyle purchase, not an investment; high-rate provinces pay back fastest regardless of latitude.
Net metering sets your export value. Ontario net metering credits exports at the retail energy rate (delivery charges excluded); Tiered/TOU plans differ.
No federal credit to lean on. Canada's Greener Homes program has wound down; the programs that remain are provincial and utility-level, listed on the Ontario payback page.
System cost. About C$25,200 for a typical 8 kW system (C$3.15/W) before incentives. Sources: Ontario Energy Board bill tracker (all-in residential rate); NREL PVWatts irradiance as of 2026-07-01.
