This estimate does not deduct the expired US federal 30% residential tax credit (ended for spending after 2025-12-31) or the closed Canada Greener Homes Grant/Loan. It also does not assume any unverified state, provincial, or utility rebate. See methodology and confirm current incentives with your state/province, utility, or a tax professional before budgeting for one.

Net Metering in Ontario
Ontario offers full net metering — you receive full retail credit for excess solar energy sent back to the grid. This maximizes your savings and shortens your payback period.
Net metering rules are set by state/provincial regulators and utilities and can change — confirm current terms with your utility before purchasing.
Utility Landscape in Ontario
Ontario runs net metering province-wide through the IESO and local distribution companies such as Toronto Hydro and Hydro One, crediting exported solar against future consumption on a 1:1 kWh basis. This is a change from Ontario's old microFIT program, a feed-in tariff that paid a fixed premium price for every kWh exported regardless of how much you used yourself — microFIT closed to new applicants years ago, so any solar economics you find quoting that era's numbers no longer apply. Today's system in Ontario is sized to offset your own usage, not to sell power at a premium.
How Solar Varies Within Ontario
Southern Ontario's Toronto–Windsor corridor gets both milder winters and more annual sun hours than Northern Ontario, where longer, colder winters push up heating-driven electricity use even as available sun hours drop — the opposite combination from what maximizes solar payback.
Worth Knowing Locally
Ontario's net metering currently limits system size to your own historical consumption (you generally can't install a system sized to export significantly more than you use), which caps how large a system makes financial sense regardless of available roof space.
What This Estimate Does Not Assume
This calculator does not automatically apply the expired US federal 30% residential tax credit, the closed Canada Greener Homes Grant or Loan, or any unconfirmed provincial or utility rebate for Ontario. If you find a currently active program, confirm it with the issuing agency — we link the general databases we trust in our methodology page.
