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
Is London Hydro involved in paying out the solar rebate?
No — the rebate cheque comes from the province's Home Renovation Savings Program, up to $5,000 for solar at $1,000/kW capped at 50% of cost. London Hydro's only role is on the net metering side, crediting surplus power you export, which is a separate arrangement you'd choose instead of the rebate, not alongside it.
Is solar worth it in London?
London averages 3.91 peak sun hours a day across the five-year stretch from 2020 to 2024 — near the top of the range for our southwestern Ontario cities. Without a rebate, payback typically runs 10–15 years depending on system size and your local electricity rates.
London Hydro won't change your rebate, but it sets your export terms
The $1,000/kW provincial rebate above lands the same whether you're on London Hydro or any other Ontario utility — that part's fixed by the province. What London Hydro does control is what happens to the power your panels generate but your house doesn't use in the moment. If you're relying on net metering to soak up surplus production, the credit terms and how unused credits carry between billing cycles come from London Hydro's own policy, not from the Home Renovation Savings Program. Call them before you finalize a system size, especially if your installer is sizing for anything beyond what you'll consume on-site.
What 3.91 peak sun hours actually buys you in London
Five years of measured solar radiation data (2020-2024) puts London at 3.91 peak sun hours a day and 14.08 MJ/m² of daily radiation — both solidly mid-pack for Ontario, not a standout either direction. For a typical 6 kW residential system, that translates to roughly 23-24 kWh of generation on an average day, more in summer and less through the darker months. It's not a dramatic number, but it's a real, measured one, and it's the figure your installer should be using in their production estimate rather than a generic provincial average.
London's own climate commitments, and where to verify them
City council's climate emergency declaration underpins London's push toward net-zero, and the Climate Action at Home hub is where the city points residents for retrofit guidance, including BetterHomes London's low-interest loan program that can run alongside the provincial rebate. For net metering specifics, London Hydro's net metering page has the current process and forms.
