The move to Solar for Ontario homeowners has never been more affordable.

Installing solar panels on your home or business dramatically reduces energy costs, protects you from price fluctuations, and increases your property’s value. Modern solar panels are efficient and have impressive warranties, and the return on investment has dropped in recent years to around five years.

The best part? There’s never been more help available to Ontario homeowners and businesses to pay for solar panel installation.

Here’s what you need to know about solar panel incentives and tax rebates in 2024.

Toronto: HELP and Hi-RIS programs

The Greater Toronto Area has several generous programs to help you pay for your panels. The Home Energy Loan Program (HELP) helps you make your home more energy efficient and reduce emissions. Through the HELP Toronto program, homeowners can borrow up to $125,000 to cover the cost of home energy improvements, including rooftop solar PV panels and battery systems. These low-interest loans can be paid off over a 20-year timeframe.

If you are a building owner, Toronto’s High-Rise Retrofit Improvement Support Program (Hi-RIS) offers low-cost financing for owners of residential apartment buildings built before 1990 of three or more storeys to make improvements that reduce energy consumption. This program lets you pay for building improvements over time, using associated energy and operational savings to offset costs. These low-interest loans have repayment terms of five-, 10-, 15- or 20-years.

Durham Region’s Deep Retrofit Rebate

Under the “check back soon” column is Durham Region’s Deep Retrofit Rebate, which offered up to $10,000 in incentives, which could be combined with the Canada Greener Homes gran and Enbridge Gas incentive. But, as of writing, and like the broader Canada Greener Homes Grant Program, the Durham Region rebate is “oversubscribed.” New solar panel rebate offerings are expected to be announced in March 2024.

The Canada Greener Homes loan

The Canada Greener Homes loan

This is a BIG ONE. The Canada Greener Homes Loan (NOT to be confused with the Canada Greener Home GRANT – more on that below) offers interest-free financing to help Canadians make their homes more energy-efficient and comfortable. The loan is intended to finance retrofits, including solar panel systems, that are recommended by an energy advisor and that have not yet been started.

Maximum Loan Amount: $40,000
Minimum Loan Amount: $5,000
Repayment term: 10 years, interest-free
Loan Type: Unsecured personal loan on approved credit

This loan is interest-free, meaning you can repay it while generating savings from your solar panels.

Greener Homes Grant

The Canada Greener Homes Grant is co-delivered by Natural Resources Canada and Enbridge Gas in Ontario under the Home Efficiency Rebate Plus (HER+) program. Homeowners receive grants for recommended and eligible retrofits, including solar panel systems. The program delivers Grants from $125 to $5,000 to get back a portion of your costs for eligible home retrofits.

The catch! The Greener Homes Grant operates on a first-come, first-served basis and, in its current incarnation, ends in March 2024. The Otter is updated on developments, so subscribe to our blog, and you’ll be the first to know what’s happening.

Don’t Forget the Financial Power of Solar Net Metering

Like the power of compound interest in your bank account is the power of Solar Net Metering.

With solar panels on your roof, you can not only significantly reduce your energy bills and decrease your carbon emissions – your meter could run backwards!

With solar panels on your roof, you can produce excess energy, which is sent back “to the grid.” You then get a financial credit for this surplus, which, in turn, further reduces your hydro bill. You can learn more about how the solar net metering program is another way to help pay for your solar panels by clicking here.
