Solar in the Greater Toronto Area isn’t a single-city market. Installers based in Toronto proper routinely also cover Mississauga, Markham, Vaughan, and North York, and a search for “Toronto solar company” turns up plenty of results that never actually leave the 905. SolarGuide tracked down 14 active installers with a genuine presence in the GTA, cross-checked each one’s Google Business Profile rating and review count by hand, and excluded several names that turned out to be lead-generation sites or out-of-province developers rather than real local installers. Combined, these 14 companies carry 1,734 verified Google reviews, averaging 4.6★.
What a Toronto Solar Installation Actually Costs
Before comparing quotes, it helps to know the range you should expect. Installed solar in the Toronto area typically runs $2.80–$3.40 per watt, so a common 10 kW residential system lands around $26,000–$34,000 before any incentives. Toronto gets roughly 1,163 kWh of production per kW of installed capacity per year — about 3.6 peak sun hours a day on average — respectable for southern Ontario, if noticeably less than what a similarly sized system produces in Calgary or Kelowna. Factor in Toronto Hydro’s time-of-use rates (more on those further down this page) and most homeowners see monthly savings in the $160–$250 range, with payback typically landing between 7 and 12 years depending on financing and whether the system pairs with any of the incentive programs covered below. For a full breakdown of financing options and step-by-step numbers, see our Ontario solar guide.

A Closer Look at Our Top 8
Solar X operates out of downtown Toronto as a 100% Canadian-owned installer, with a review count that dwarfs every other GTA company in our dataset. Its residential, commercial, and agricultural install work stretches well beyond the city core to Ottawa, Hamilton, London, Kingston, and Barrie.
This Toronto location is part of Polaron’s larger national network, marketed as one of the biggest residential solar installers operating across multiple Canadian provinces. Locally, it handles both residential and commercial projects out of its Victoria Park Avenue address.
Solify is based in North York and focuses on residential installations across the wider GTA. It’s one of the higher-volume installers on this list without belonging to a national franchise network.
Blue Sky is headquartered in Mississauga and installs both residential and commercial systems, with a footprint that extends beyond the GTA nationally. A perfect 5.0★ average across 110 reviews is a rare combination of volume and consistency.
Goldwater has been installing solar in the GTA for more than 15 years out of its Fort York Boulevard office, covering residential, commercial, and institutional projects. Its 4.9★ average is among the strongest of any installer with a meaningful review count.
New Dawn is an ECRA/ESA-licensed installer based in Markham, serving Markham, Mississauga, Richmond Hill, Vaughan, and as far out as Hamilton and London. It focuses on residential installations.
Terawatt is also based in Markham and is ECRA/ESA-licensed. What sets it apart is that it keeps electrical work in-house rather than subcontracting it out, which isn’t the norm among smaller installers.
Radiant is a Vaughan-based residential installer with a perfect 5.0★ average across its 31 reviews, serving customers throughout the GTA.
Toronto's Net Metering & Incentive Landscape
Toronto Hydro runs net metering under Ontario Regulation 541/05, credited 1:1 — a kWh you export offsets a kWh you’d otherwise buy, at the same rate. Credits bank forward for up to 12 months before they expire, rather than settling out immediately, which matters if your system is sized to overproduce in summer and draw down in winter. Applications go through Toronto Hydro’s Generation and Storage Capacity Lookup Tool, or you can reach their distributed energy resources team directly at der@torontohydro.com or 416-542-3099.
Any installer working in Toronto needs an ECRA/ESA license issued by the Electrical Safety Authority — Ontario’s equivalent of the electrical-contractor licensing BC requires, or the APEGA engineering sign-off Alberta requires. It’s worth asking to see this license directly rather than taking a company’s word for it.
The City of Toronto’s Home Energy Loan Program (HELP) offers financing up to $125,000 (or 10% of your property’s value, whichever is lower) at a 4.75% fixed rate through September 30, 2026, with a 20-year term available for solar. Unlike HELP’s whole-home retrofit stream, a solar-only project doesn’t require a pre- or post-installation energy assessment.
Separately, the IESO’s Home Renovation Savings program, marketed as Save on Energy, offers up to $10,000 in combined solar-and-battery rebates province-wide, running on a first-come basis through late 2026. One catch worth flagging: our own Ontario solar guide notes that HRS funding generally isn’t permitted to be combined with net metering on the same system, so it’s worth having an installer walk through which program actually nets out ahead for your situation before committing to either.
Toronto Hydro bills on time-of-use pricing by default: 9.8¢/kWh off-peak, 15.7¢/kWh mid-peak, and 20.3¢/kWh on-peak, with a flat tiered alternative (12.0¢ up to a monthly threshold, 14.2¢ beyond it) and an opt-in Ultra-Low Overnight rate (3.9¢ overnight, 39.1¢ on weekday afternoons and early evenings). Which structure works best with solar depends heavily on your export pattern — an installer should be able to model this against your actual bill rather than quoting a generic payback number.
Before You Sign: Questions Worth Asking in the GTA
A 667-review company and a 10-review company can both do excellent work — and both can also cut corners. Review volume is a signal, not a guarantee, especially in a market as fragmented as the GTA, where a company’s Google listing might say “Toronto” while its install crews are based an hour away. The questions below apply whether or not the installer you’re considering appears in our ranking above.

How This Ranking Was Built
This ranking is built entirely from verified Google review counts, checked one company at a time against each business’s actual Google Business Profile — never self-reported numbers, and never a paid placement. We pulled every installer with a credible GTA presence, then manually excluded listings that didn’t hold up under scrutiny: two utility-scale project developers, one lead-generation site using an installer-sounding name, and one company with a Toronto-listed profile but no visible install history outside another province. A high review count, by itself, is a starting filter — not proof of quality — which is why the questions-worth-asking section above exists.
Toronto Solar Company FAQs
How does Toronto Hydro's net metering program work?
Toronto Hydro credits exported solar power 1:1 against what you draw from the grid, under Ontario Regulation 541/05. Unused credits bank forward for up to 12 months rather than expiring immediately. Applications go through Toronto Hydro’s Generation and Storage Capacity Lookup Tool, or you can contact their distributed energy resources team at der@torontohydro.com.
Can I combine the HRS rebate with net metering in Toronto?
Generally, no — the IESO’s Home Renovation Savings program isn’t typically permitted to be combined with net metering on the same system. Confirm the current rules directly with your installer or IESO before assuming both apply to your project.
Do these 14 installers only serve the City of Toronto, or the wider GTA too?
Most serve the wider GTA rather than just the old City of Toronto boundaries — several of the companies on this list are based in Markham, Mississauga, Vaughan, or North York and work across multiple municipalities. Confirm coverage for your specific address before requesting a quote.
What license should a Toronto solar installer have?
Look for an ECRA/ESA license issued by Ontario’s Electrical Safety Authority. A reputable installer will show you this directly when asked.
How much can I expect to pay for solar in Toronto?
Installed solar in the Toronto area typically runs $2.80–$3.40 per watt, putting a common 10 kW residential system around $26,000–$34,000 before incentives. See our Ontario solar guide for a full cost breakdown, or run your address through our solar calculator for a personalized estimate.
