Program names, amounts, and eligibility rules change and are set by the administering government body or utility, not by Terawatt Solar. This page is a general overview as of this writing. We confirm current terms for your specific property and utility as part of every free quote.

The Short Version

Ontario homeowners going solar in 2026 are mainly choosing between two paths: take the Home Renovation Savings Program (HRSP) rebate upfront and reduce your install cost directly, or skip the rebate and enroll in net metering, banking every surplus kilowatt-hour as a bill credit for the life of the system. You cannot do both on the same system. Layered on top of either path, select GTA municipalities offer low-interest, property-tax-repaid financing, and commercial projects have an entirely separate federal tax credit available to them. We walk every client through which combination actually nets out ahead for their property during a free quote, using our solar calculator to run real numbers against your actual usage.

Why the Federal Greener Homes Programs Aren't Listed Below

If you've seen older articles referencing the Canada Greener Homes Grant or the Canada Greener Homes Loan, both are closed to new applicants as of this writing, the Grant since early 2024 and the Loan since late 2025. We've left them off the table below so you're not chasing a program that no longer exists. The live Ontario-specific programs are listed here instead.

Figures reflect publicly available program terms as of this writing and are not a guarantee of your eligibility or funding availability. Net metering and HRSP amounts assume a typical 9-10 kW residential system; your actual numbers depend on roof, usage, and utility.

Pick Your Path

Rebate Now vs. Net Metering Long-Term

Both paths can be the right call, it depends on your usage, roof, and how long you plan to own the home. Here's the tradeoff in plain terms.

Take the HRSP Rebate

Best if you want a lower upfront cost and plan to pair solar with a battery on the ultra-low overnight rate.

Upfront value: up to $5,000 off solar, up to $5,000 off a battery.

Tradeoff: you give up 1:1 net metering credits on that system permanently.

Requires pre-approval before installation begins.

Enroll in Net Metering

Best if you expect strong, consistent annual production and want long-term bill credits instead of an upfront rebate.

Ongoing value: every surplus kWh exported is credited 1:1 against future usage, for the life of the system.

Tradeoff: no HRSP rebate, and unused credits reset after a 12-month rollover window.

Requires a utility interconnection application, which we file for you.

We model both scenarios against your actual utility bills and roof data before you decide, there's no universal right answer.

Municipal Financing Across the GTA

Several Ontario municipalities run their own low-interest financing for home energy upgrades, repaid as a line item on your property tax bill rather than a traditional loan. Programs like this have operated under names such as the Toronto Home Energy Loan Program and Ottawa's Better Homes Loan, with similar structures appearing in other regions including Durham and Guelph. Funding and eligibility are set by each municipality and can run out before the program year ends, so we check current availability for your specific city, including Toronto, Markham, Mississauga, Vaughan, and Oakville, as part of your proposal. See our full Toronto Home Energy Loan Program (HELP) guide for how that loan is structured and repaid.

Commercial and Business Incentives

Businesses installing commercial solar are generally eligible for the federal Clean Technology Investment Tax Credit, worth up to 30% of eligible system cost, alongside accelerated capital cost allowance treatment that lets you write off equipment faster. Commercial projects don't qualify for the residential HRSP rebate, so we build a separate financial model for business clients that accounts for the tax treatment your accountant will actually file. See our full Clean Technology ITC guide for the rate structure and labour conditions.

FAQ

Common Questions About Ontario Solar Incentives

Is there a solar rebate in Ontario right now?
Yes. The Home Renovation Savings Program (HRSP) offers up to $5,000 toward solar panels and up to $5,000 toward a battery, for a combined cap of $10,000, with pre-approval required before installation. The federal Greener Homes Grant and Loan are both closed to new applicants.
Can I get the HRSP rebate and net metering at the same time?
No, the two are mutually exclusive on the same system. You choose one upfront rebate path or one long-term credit path. We run both scenarios against your actual usage so you can see which nets out ahead.
How does net metering work in Ontario?
Surplus solar production flows back to the grid through a bidirectional meter and is credited 1:1 against electricity you draw later. Credits roll over for up to 12 months before resetting to zero. See our full net metering guide, or the Toronto Hydro-specific breakdown if you're inside the city.
What size system qualifies for simplified net metering approval?
Most utilities process systems at or below the micro-generation threshold, 10 kW at some utilities and 12 kW at others following a 2026 OEB update, through a simplified connection process.
Are there incentives for commercial solar?
Yes, businesses can generally claim the federal Clean Technology ITC, worth up to 30% of system cost, plus accelerated capital cost allowance. Commercial projects aren't eligible for the residential HRSP rebate. See our commercial solar page for how these stack.
Do any GTA cities offer solar financing?
Several municipalities run property-tax-repaid financing for home energy upgrades. Toronto's Home Energy Loan Program (HELP) is the most established example. Availability and funding depend on your specific city, which we check as part of your quote.
How do I know what I personally qualify for?
