Ontario Solar & Battery Rebate 2026: Up to $10,000 Back

Ontario's main solar incentive in 2026 is the Home Renovation Savings Program, run by Save on Energy and Enbridge Gas. It pays homeowners up to $5,000 for rooftop solar panels and up to $5,000 for a paired battery — a combined $10,000 back. This guide covers exactly how much you get, who qualifies, the rules that quietly get rebates rejected, and how to apply.

Status, October 15, 2026: the official program pages show the solar and battery rebates open, at the same amounts, with no published end date. Earlier reports pointed to November 30, 2026, and the program's terms let it close at any time. Pre-approval has to come before you buy anything, so if you want this rebate, talk to an installer now.

The quick version: Up to $10,000 total ($1,000/kW for solar, $300/kWh for a battery, each capped at 50% of what you spend). You must choose between this rebate or net metering — you can't have both. And you must get written pre-approval before you buy or install anything.

How much is the Ontario solar and battery rebate?

There are two separate rebates, and you can claim one or both:

• Solar panels: $1,000 per kW installed, up to $5,000, and no more than 50% of the total cost.
• Battery storage: $300 per kWh, up to $5,000, and no more than 50% of the total cost.

Your payout is always the lower of the two limits — the size formula, or half of what you actually spent. To max out the $5,000 solar rebate, you need a system of about 5 kW and a project cost of roughly $10,000 or more. To max out the $5,000 battery rebate, you need around 16.7 kWh of storage. Solar and battery under this program do not require a home energy assessment.

How the rebate math actually works

Two limits decide your cheque: the size formula and the 50%-of-cost cap. On a well-priced 5 kW-plus system the size formula sets your number; on a smaller or pricier job the cost cap sets it. Here's how that plays out:

Rebate or net metering? You have to choose one

This is the most important decision in your whole project, and most sites skip it. If you take the Home Renovation Savings rebate, you cannot be on net metering. The program funds systems built for load displacement only — the power your panels make is used in your home, not exported to the grid for credit.

So you pick one path before your system is designed:

• Rebate path: up to $10,000 up front, but your system is sized to serve your own home, with no export.
• Net metering path: no upfront rebate, but you earn bill credits for exported power for the life of the system.

If you use most of your own solar (you're home during the day, you drive an EV, or you're adding a battery), the rebate path usually wins. If your panels would export a large share of what they make, net metering's lifetime credits can be worth more. The only way to know is to run it against your real hydro bill.

Who qualifies for the Ontario solar rebate?

Eligibility trips up more people than the money does. This chart covers the situations that actually come up:

The rules that get rebates rejected

None of these are hard, but each one has cost homeowners their rebate:

1. Pre-approval comes first. Your contractor submits a pre-installation application on your behalf, and you need written pre-approval before buying or installing anything. There is no retroactive approval.
2. Rooftop only. Ground-mounted panels don't qualify.
3. The battery must pair with new solar. A standalone battery, or one added to an existing system later, generally won't qualify.
4. Your quote has a 60-day shelf life. The quote in your application must be dated within 60 days of submission.
5. Both caps apply. The per-kW (or per-kWh) rate and the 50%-of-cost cap both apply; you get the lower number.
6. Use a registered contractor. DIY installs can't claim the rebate.
7. Not every dollar counts. Costs like HST, financing charges, and insurance typically don't count toward the amount the 50% cap is measured against.

Why add a battery in Ontario?

Ontario's Ultra-Low Overnight (ULO) electricity plan makes overnight power very cheap and weekday evening power very expensive: 3.9¢/kWh from 11 p.m. to 7 a.m. versus 39.1¢/kWh from 4 to 9 p.m. on weekdays (prices in effect through October 31, 2026; the Ontario Energy Board resets them every November 1). A battery lets you store your solar through the day and run your home on it during that evening peak instead of buying from the grid at the worst rate. It also keeps essentials running during an outage. For homes on ULO, that daily peak-shaving is often what tips the rebate path ahead of net metering.

When solar isn't the right call

Solar and a battery aren't right for every home. Hold off if your roof is heavily shaded most of the day, if it needs replacing within a few years (do the roof first; see Roof first), if you're planning to move soon, or if your hydro use is very low. In those cases the rebate won't fix the underlying math.

How to apply, step by step

1. Confirm eligibility using the chart above.
2. Get a quote and written pre-approval through a registered contractor — before buying anything.
3. Install to program spec once approved: rooftop, sized for load displacement, battery paired to new solar.
4. Submit and get paid — your contractor files the post-install paperwork and your rebate follows.

Frequently asked questions

Can I claim the federal 30% tax credit on top of this rebate?

No. The federal 30% Clean Technology Investment Tax Credit is for businesses, not individual homeowners. Any site telling a homeowner they can stack it is wrong.

Can I add a battery later and still get its rebate?

Not the same way. The battery has to go in with a new solar system and be sized to it. A battery added to an existing system afterward generally won't qualify.

Does a bigger system always mean a bigger rebate?

Only up to the caps. Past about 5 kW of solar or 16.7 kWh of battery, the rebate stops growing — and on cheaper jobs the 50%-of-cost cap limits you first.

Can I put the panels on the ground?

No. Only rooftop panels on the home or a permanent structure on the same hydro meter qualify. Ground and pole mounts are excluded.

What happens if I install before I'm approved?

You lose the rebate. Written pre-approval has to come first, every time.

Is there a deadline for the Ontario solar rebate in 2026?

As of October 15, 2026 the official program pages show the solar and battery rebates open with no published end date. Earlier reports pointed to November 30, 2026, and the terms allow the program to close at any time. Past Ontario rebates have ended with little notice, so confirm the current status before you commit.
