As energy costs in the GTA rise, many homeowners are searching for a reputable solar company in Toronto to take more control of their power bills. Terawatt Solar designs and installs high-efficiency rooftop solar for Toronto and Ontario homes, built for our climate and our utilities. This page explains how solar works for a Toronto home today, what to expect on cost and payback, and how to choose an installer you can trust.
For many Toronto homeowners, yes. The federal Canada Greener Homes Grant has closed to new applicants, so there is no longer a large up-front federal grant to lean on. What remains is the long-term economics: a system that produces your own power for decades while delivery charges and rates continue to move. Whether solar makes sense for your home depends on your roof, your usage and how you plan to use the system, which is why we start every project with a free site assessment instead of a one-size-fits-all quote.
Update (2026): Programs and rates change often. For the current rebates, loans and utility programs, please check our Ontario solar incentives page before you finalize a budget.
How it works: your panels power your home first, and any surplus is sent to your utility (Toronto Hydro, Hydro One and others) and credited against your future bills.
Pros: lower up-front cost because no battery is required, and a simple credit system.
Cons: no backup power during a grid outage, because a standard grid-tied system shuts down for safety when the grid goes down.
How it works: a battery stores solar energy so you can use it later, for example during higher-priced evening hours under time-of-use pricing, or as backup during an outage.
Pros: backup power, and the ability to shift your own consumption away from peak rates. Provincial rebates for battery storage have been offered through programs such as the Home Renovation Savings Program, so see the home renovation program page for current terms.
Cons: a higher initial equipment cost. Read more about our battery storage service.
The cost of a residential solar system in Toronto depends on system size, the equipment used, roof complexity, electrical upgrades and the installer. A larger home with higher usage needs a larger array than a small townhouse, and a battery adds to the price. Equipment costs have come down significantly over the past decade, which has made solar more accessible for homes and businesses alike.
The right comparison for your property is a written proposal showing the system size, equipment, projected production and price. We recommend asking for quotes for both options above (net metering only, and solar plus battery) so you can compare the math side by side. Terawatt Solar provides both at no cost, and you can start with the solar calculator for a ballpark.
Solar works as a hedge against rising electricity costs. Once your system is installed, a large share of your electricity is produced on your own roof instead of purchased at changing rates. Payback periods vary widely with system cost, usage, rates and available incentives, so we model yours individually rather than quoting a generic number. Over the 25-plus year life of a quality system, continuing to pay full grid rates is also an expense that builds no equity in your home.

Toronto Hydro offers net metering for solar. Because panels produce power in peaks and valleys, with high output on sunny afternoons and little at night, net metering lets you send surplus electricity to the grid and receive a credit when you draw from the grid later. To connect, your system must meet the technical requirements set by the utility and Ontario's regulations; the Ontario Energy Board publishes information on the regulatory framework. We prepare and submit the interconnection application for you. Our guide to net metering with Toronto Hydro walks through it step by step.
A solar system should perform for 25 years or more, so the installer you choose matters as much as the panels. Before you sign, check that your Toronto solar company meets these standards:
Start by providing basic property details. Our team uses satellite imagery to do an initial assessment of your roof's orientation and shading.
Schedule a brief consultation with a Toronto solar advisor to talk through your energy goals and your questions about net metering or battery backup.
To size a system properly, we need your recent electricity usage. Your bill lets us calculate your annual energy offset and projected savings.
We present a 3D model of your home with a tailored array layout, along with a clear cost estimate, a projected payback period and a full equipment list that includes SolarEdge inverters.
Once you approve the design, we handle the logistics: the utility interconnection application, building permits and the installation itself.
Terawatt Solar is located at 7030 Woodbine Ave, Suite 500, Markham, Ontario, L3T 6G2, just north of Toronto and easy to reach from Highway 404 (Woodbine Avenue exit). We are open Monday to Friday, 8:00 am to 5:00 pm. For questions, call (877) 648-3323 or send us a message. You can also see our Toronto service area page and real GTA case studies.
Cost depends on system size, equipment, roof complexity and whether you add a battery. A free site assessment gives you a written, home-specific price.
Yes. Surplus solar electricity is sent to the grid and credited against future bills, subject to utility rules and technical requirements. We handle the interconnection application for you.
A standard grid-tied system shuts off during an outage for safety. A solar plus battery system can provide backup power; see our battery storage page.
