How much you get
The net-metering tradeoff
You can't take this rebate and also sign a net-metering agreement with your local utility. The rebate is for "load displacement" — using the power you generate yourself, not exporting surplus.
How to claim it
- Confirm eligibility via a quick form
- Select a contractor and get written pre-installation approval
- Installation is completed
- Contractor handles utility interconnection approval
- Rebate arrives after documentation is submitted

Common questions
Markham already has solar on its own buildings — does that mean a bigger rebate for residents?
No, the two aren't connected. The city's own municipal solar (2.1 MW installed on city facilities as part of its energy management program) is separate from what homeowners get, which is the province's Home Renovation Savings Program: up to $5,000 for solar at $1,000/kW, capped at 50% of project cost, the same figure across Ontario.
Is solar worth it in Markham?
Markham gets 3.88 peak sun hours a day on average, measured over 2020-2024 — right in the middle range for the GTA, not a standout in either direction. Without a rebate, payback typically runs 10–15 years depending on system size and your local electricity rates.
Markham's power comes from the utility that swallowed several others
Markham was one of the founding territories of Alectra Utilities when PowerStream, Enersource, Horizon Utilities, and Brampton Hydro combined in 2017 to form what's now one of Ontario's largest local distribution companies. Your solar rebate is untouched by any of that — it's a flat provincial number — but Alectra is who you deal with for interconnection approval and net metering credit terms once your system is installed, and a utility this size tends to have a more standardized (if not always faster) process than a small single-city operator. Confirm their current net metering terms directly before you commit to a system size built around exporting surplus power.
What Markham's sun-hour number means for a typical system
At 3.88 peak sun hours a day and 13.97 MJ/m² of daily radiation (five-year average, 2020-2024), a 6 kW system in Markham lands somewhere around 22-23 kWh of generation on a representative day — solid but unremarkable by Ontario standards. The number matters less on its own than paired with your actual roof orientation and shading, which is where most of the real variation between two Markham homes will show up.
Where Markham's own numbers come from
The city's Municipal Energy Plan, branded "Getting to Zero," is the source for Markham's net-zero-by-2050 target and its own solar installations. York Region's homeowners can also plug into the Climate Action Partnership, a regional non-profit tracking municipal progress across York Region including Markham specifically. For net metering forms, Alectra's site has the current process.
