1. Introduction: Why Go Solar in Toronto?
Solar panels Toronto homeowners install in 2026 are delivering steady, dependable returns — even without Alberta-level sunshine — thanks to the city’s 2,066 annual sunshine hours, Ontario’s tiered and time-of-use electricity rates (9.8¢ to 20.3¢/kWh depending on when you use power), and Toronto Hydro’s 1:1 net metering that credits every kWh you send back to the grid at full retail value. Whether you’re searching for the best solar companies in Toronto, comparing Ontario’s Home Renovation Savings rebate for 2026, or ready to get competing quotes, this guide covers current installed costs ($2.80–$3.40/watt), active 2026 incentives, Toronto Hydro’s net metering process, and Toronto’s top-rated local installers.
Modern solar technology performs well in Toronto’s four-season climate, including in winter, when cold temperatures actually improve panel efficiency and snow typically slides off within a day or two. With residential electricity rates climbing and Ontario’s Home Renovation Savings program offering up to $5,000 toward a solar installation, a properly sized system can offset 80-100% of a typical home’s annual electricity consumption. Most Toronto homeowners see payback periods of 7-12 years, followed by decades of essentially free electricity from their solar panel system.

2. Does Solar Work in Toronto?
Toronto’s solar potential is solid, if not the best in Canada — the city receives an average of 2,066 hours of sunshine annually and roughly 1,270 kWh/m²/year of global horizontal irradiance. That puts Toronto ahead of Vancouver (about 1,190 kWh/m²/year) but behind sunnier, drier markets like Calgary (about 1,350 kWh/m²/year). Toronto sits at latitude 43.7°N, considerably further south than Calgary, with peak summer days stretching to roughly 15.5 hours of daylight in late June.
Winter solar production in Toronto is more modest than in the Prairies — typically 20-28% of annual output falls in the October-March window, since Toronto sees more persistent cloud cover and lake-effect snow than Calgary’s drier, chinook-cleared winters. Snow still reflects useful light onto panels and generally slides off within a day or two on a properly pitched roof. Optimal panel tilt for Toronto’s latitude is 30-40°, which balances summer and winter production across the year.
A 1 kW solar system in Toronto typically produces 1,150-1,200 kWh annually, depending on site conditions and orientation, with a citywide average of about 1,172 kWh/kW. Combined with Toronto Hydro’s 1:1 net metering, this makes Toronto a genuinely solid solar market — though Ontario homeowners should budget for 13% HST on equipment, since the province does not offer Alberta’s no-PST advantage. For detailed information on solar potential across the province, visit our comprehensive Ontario solar guide.
| System Size | Est. Annual Production (kWh) | % of Average Home Usage |
|---|---|---|
| 5 kW | 5,600-6,100 | 50-60% |
| 8 kW | 9,000-9,750 | 80-90% |
| 10 kW | 11,250-12,200 | 100-110% |
| 12 kW | 13,500-14,650 | 120-135% |

Pro Tip: Toronto homes with south-facing roofs at 30-40° pitch achieve optimal solar production, but southeast and southwest orientations still generate 90-95% of peak output. Many Toronto neighbourhoods — especially in Etobicoke, Scarborough, and North York — feature detached and semi-detached homes with multiple roof planes, letting installers design around dormers, chimneys, and vents. Downtown rowhouses and semis often have smaller, more complex roofs with more shading from mature tree canopy, so a site assessment matters more there than in the suburbs. Avoid north-facing installations, which typically produce 35-40% less energy at Toronto’s latitude.
3. Solar Panel Cost in Toronto (2026): What Homeowners Pay
The solar panel cost in Toronto averages $2.80–$3.40 per watt installed, slightly above Alberta’s provincial average due to higher labour and permitting costs in the GTA. Toronto’s large, competitive installer market helps keep quoted prices honest, while ECRA/ESA licensing requirements and established local contractors contribute to reliable, well-documented installations. Local factors such as roof accessibility, electrical panel upgrades, and system complexity can influence final pricing, but Toronto homeowners generally benefit from transparent, competitive pricing in a mature local solar market.
| System Size | Cost Before Incentives | Cost After Incentives | Payback Period |
|---|---|---|---|
| 5 kW | $14,000-$17,000 | $9,000-$12,000 | 10-12 years |
| 8 kW | $22,400-$27,200 | $17,400-$22,200 | 9-11 years |
| 10 kW | $28,000-$34,000 | $23,000-$29,000 | 9-11 years |
| 12 kW | $33,600-$40,800 | $28,600-$35,800 | 7-10 years |

- Solar + EV Charging: Adding a Level 2 EV charger during your solar installation in Toronto is cost-effective. Your panels can offset a significant portion of EV charging costs, and the combined install typically adds only $800–$1,500 versus a standalone charger.
Toronto’s competitive solar market occasionally sees companies offering below-market pricing to win business. Be cautious of quotes significantly below $2.60/watt, as they may indicate substandard equipment, unlicensed installers, or companies that will add unexpected costs later. Always verify ECRA/ESA licensing and get detailed written quotes.
4. Solar Incentives & Rebates in Toronto (2026)
Solar rebates in Toronto for 2026 centre on Ontario’s Home Renovation Savings (HRS) program and the City of Toronto’s HELP loan. While federal grant programs have recently closed, Ontario homeowners can still access a meaningful rebate plus low-cost municipal financing repaid through their property tax bill. These incentives, combined with Toronto Hydro’s net metering program, create workable (if not spectacular) economics for residential solar in Toronto — you just have to actually apply for them, since nothing here is automatic.
✅ Home Renovation Savings Program (HRSP) — Up to $5,000 for Solar
Key benefits of HELP financing include:
- 4.75% fixed interest rate (rate locked through September 30, 2026) — well below typical unsecured loan rates
- No upfront costs or down payment required
- Repayment tied to the property, not the homeowner
- Transferable to new owners if the home is sold
- No energy audit required for solar-only projects (unlike some other HELP-eligible upgrades)
✅ Toronto HELP Loan — Up to $125,000 via Your Property Tax Bill
Unlike Alberta, Ontario does not offer a solar sales-tax break. Toronto homeowners pay the full 13% HST on solar equipment and installation services, which adds roughly $2,800–$4,600 to a typical 10 kW residential system compared to Alberta’s GST-only rate. There is currently no provincial program that offsets this tax directly.
The good news: solar panels do not trigger a higher property tax reassessment in Ontario. While adding solar panels increases your home’s resale value, the Municipal Property Assessment Corporation (MPAC) does not reassess based on rooftop solar additions, so you keep the value benefit without a higher annual tax bill. Always consult with your tax professional regarding the specific tax implications of your solar installation.
❌ Canada Greener Homes Loan – CLOSED
The Canada Greener Homes Loan closed in October 2025 and is no longer accepting new applications. This federal financing option is not available to Toronto homeowners.
❌ Canada Greener Homes Grant – CLOSED
The Canada Greener Homes Grant closed on March 31, 2024 and is no longer available.
| Incentive / Program | Type | Benefit | Status |
|---|---|---|---|
| Home Renovation Savings (HRS) | Provincial Rebate | $1,000/kW up to $5,000 for solar (plus up to $5,000 more for battery storage, $10,000 combined cap) | ✅ Active (first-come, first-served) |
| City of Toronto HELP Loan | Property Tax Financing | Finance up to $125,000 (or 10% of property value) over 20 years at 4.75% fixed | ✅ Active (rate through Sept 30, 2026) |
| HST on Solar Equipment | Tax | 13% HST applies — Ontario has no equivalent to Alberta’s no-PST advantage | ℹ️ Applies to all installs |

| Canada Greener Homes Grant | Federal Grant | Previously up to $5,000 | ❌ Closed (March 2024) |
| Canada Greener Homes Loan | Federal Loan | Previously up to $40,000 interest-free | ❌ Closed (October 2025) |
5. Ontario Net Metering Explained
Toronto homeowners benefit from Ontario’s net metering program, governed by Ontario Regulation 541/05 and administered locally through Toronto Hydro. Net metering allows solar system owners to receive credit for excess electricity their panels generate beyond what their home consumes. During sunny periods when production exceeds usage, the excess power flows back to the grid and homeowners receive credits on their electricity bill at the full retail rate for their chosen rate plan — not a flat wholesale rate. Unlike some Alberta utilities, Toronto Hydro does not currently offer a seasonal premium export rate, so the credit rate simply tracks whatever TOU, Tiered, or ULO price applies when your panels are exporting.
These credits accumulate throughout the year and can offset electricity consumption during lower production periods, such as winter months or cloudy days. Ontario’s net metering program operates on a 12-month cycle, meaning credits earned during high-production summer months can offset winter electricity bills. Any remaining credits at the end of the 12-month period are typically forfeited, making it important to size your solar system appropriately to maximize the value of all generated electricity. Toronto Hydro handles interconnection applications and provides the bi-directional meter required for net metering at no additional cost to qualifying residential customers. For comprehensive information on solar costs across Canada, review our Canadian solar panel costs guide.
Key Details for Toronto Homeowners
- Credit Rate: Credited at the full retail rate for your chosen rate plan (TOU, Tiered, or ULO)
- Credit Expiry: 12-month cycle under O. Reg. 541/05, with credits resetting annually
- Interconnection Cost: Free bi-directional meter installation by Toronto Hydro
- System Size Limit: Simplified micro-generation process for systems up to 10 kW; larger systems require additional review
Pro Tip: Size your Toronto solar system to generate 90-100% of your annual electricity usage rather than oversizing. Toronto’s seasonal production variation means summer overproduction helps offset winter shortfalls, but excess credits beyond your annual usage provide minimal value once the 12-month cycle resets. A properly sized system maximizes your financial return while ensuring you use all the solar energy you generate throughout the year.
Two details most Toronto guides get wrong: first, exported solar is credited at whatever rate applies on your plan at the moment you export — not a flat number. Under Time-of-Use pricing, most of your panels’ peak summer production happens around midday, which typically falls in the mid-peak window (15.7¢/kWh), not the more lucrative on-peak window (20.3¢/kWh) that hits later in the afternoon — so your average credit usually lands closer to mid-peak than the headline on-peak rate. Second, Ontario’s Home Renovation Savings rebate and net metering generally can’t be combined on the same system: you typically choose one path or the other, and that choice should be based on your actual usage pattern, not just the sticker price of the rebate.

Cash Purchase
Cash purchases offer the highest return on investment for Toronto homeowners, with typical payback periods of 7-12 years followed by 15-25 years of low-cost electricity. With no interest payments or financing fees, cash buyers maximize their solar savings and often see internal rates of return in the 6-10% range annually based on current Toronto electricity rates.
HELOC (Home Equity Line of Credit)
Home Equity Lines of Credit (HELOCs) provide Toronto homeowners with flexible, low-interest financing for solar installations. With major Canadian banks offering HELOC rates of 6-8%, homeowners can leverage their home equity — often substantial in the Toronto market — to fund solar projects while maintaining cash flow. HELOC interest may be tax-deductible if the solar system is considered a home improvement, though homeowners should consult with their tax advisor for specific guidance.
Installer Financing
Many Toronto solar installers partner with financing companies to offer solar loans with terms ranging from 5-20 years. Interest rates typically range from 6-12% depending on creditworthiness and loan terms. When comparing installer financing options, always request both cash and financed pricing, as financed quotes may include dealer fees. Some installers mark up financed systems by 10-20% to cover financing costs and commissions.
Solar leases and Power Purchase Agreements (PPAs) are rarely beneficial for Toronto homeowners given Ontario’s net metering and the HRS rebate and HELP loan now available. These arrangements typically provide minimal savings while preventing homeowners from accessing provincial incentives and the full financial benefits of solar ownership. Cash purchase or traditional financing almost always provides superior returns.

8. The Solar Installation Process in Toronto
Solar installation in Toronto typically takes 8–14 weeks from initial consultation to system activation, depending on permitting timelines and equipment availability. The process begins with a detailed site assessment where installers evaluate your roof condition, electrical system, and energy usage patterns. Following the assessment, installers create a custom system design and apply for City of Toronto building permits, which typically take 2-3 weeks to approve for standard residential installations.
Once permits are approved, the physical installation usually takes 1-2 days depending on system size and complexity. Professional installers coordinate all inspections, including the Electrical Safety Authority (ESA) inspection and final approvals. The final step involves Toronto Hydro net metering interconnection approval and bi-directional meter installation, which can take 3-6 weeks to complete. Throughout the process, homeowners need to provide utility bills for system sizing, sign interconnection agreements, and ensure roof access for installers and inspectors.
Toronto’s large, established contractor base helps ensure efficient installations with minimal disruption to homeowners, though the City’s permitting volume can occasionally run slower than smaller markets. Most installers provide project timelines and regular updates throughout the process, keeping customers informed of progress and any potential delays due to weather or utility scheduling.
| Installation Phase | Responsibility | Typical Timeline |
|---|---|---|
| Site Assessment & Design | Installer | 1-2 weeks |
| Permits & Engineering | Installer | 2-3 weeks |
| Equipment Ordering | Installer | 2-6 weeks |
| Physical Installation | Installer | 1-2 days |
| ESA Inspection | Electrical Safety Authority | 2-3 weeks |
| Utility Interconnection | Toronto Hydro | 3-6 weeks |
What the timeline actually looks like in Toronto: your installer pulls City of Toronto building and electrical permits, gets the work inspected by the Electrical Safety Authority (ESA), and files the net metering / micro-generation application with Toronto Hydro on your behalf. After installation (typically 1–2 days on the roof) and ESA sign-off, Toronto Hydro schedules the swap to a bi-directional meter — only then do exports start earning net metering credits. End to end, most straightforward Toronto installs run about 8–14 weeks from signed contract to energized system; older wiring, panel upgrades, or a backlog at Toronto Hydro can extend that.

Solar Panels Across Toronto's Neighbourhoods
Solar panels Toronto homeowners install are spread across every corner of the city, from the detached bungalows of Scarborough to the dense rowhouses of downtown. Toronto’s mix of housing stock — and its patchwork of tree canopy, roof ages, and lot sizes — means solar potential varies more by neighbourhood here than in newer, more uniform suburbs. Here’s how solar performs across Toronto’s main districts.
Etobicoke (Islington, Kingsway, Mimico, Rexdale) — A mix of post-war bungalows and larger detached homes on generous lots, many with unobstructed south-facing roof exposure. Ideal system size: 7–10 kW. One of Toronto’s stronger ROI areas thanks to open sky and larger roof planes.
Scarborough (Agincourt, Malvern, Guildwood, Highland Creek) — Predominantly detached and semi-detached homes on wider lots than the downtown core. Historically strong demand for solar among owner-occupied households, and most homes need no electrical panel upgrade before installation.
North York (Willowdale, Don Mills, Bayview Village, Downsview) — A mix of large suburban detached homes and higher-density condo and rental buildings; solar makes the most sense for the detached and low-rise segment, where roof orientation and pitch tend to be favourable.
East York & Leaside — Established mid-century neighbourhoods with moderate-sized roofs and mature tree cover in places. Homes here often sit on 25–40 ft lots, so a site assessment for shading matters more than in newer suburbs.
Downtown & Old Toronto (Annex, Riverdale, Leslieville, Cabbagetown) — Older semi-detached and row houses may need a 100A→200A panel upgrade ($1,500–$3,000) before solar can be added. Smaller roofs and tree-canopy shading are more common here, but high electricity usage keeps ROI reasonable at a 9–13 year payback. Condo and high-rise residents generally can’t install solar directly — check with your building’s board about any shared rooftop programs.
York & Weston (Mount Dennis, Weston, Rockcliffe-Smythe) — A mix of older detached and semi-detached homes, many with roofs original to the 1950s-60s building boom. A roof condition check (and possible reroofing before installation) is worth budgeting for, given the area’s housing age.
Pro Tip: Regardless of neighbourhood, the most important factor for solar production is roof orientation. South-facing roofs at 30–40° produce optimal output. Southeast and southwest-facing roofs still generate 90–95% of peak output, and most Toronto homes can be designed around these constraints — but mature tree canopy, common in Toronto’s older neighbourhoods, is worth having assessed on-site before you commit to a system size.
Toronto Hydro Rate Plans: TOU vs. Tiered vs. Ultra-Low Overnight
Toronto is served by a single electricity distributor, Toronto Hydro, which covers the entire city. Where Calgary or Edmonton homeowners have to figure out which of two utilities they’re on, every Toronto address deals with the same distributor — what actually varies is which rate plan you’re billed on: Time-of-Use (TOU), Tiered, or Ultra-Low Overnight (ULO). Your rate plan determines how much your net metering credits are worth at different times of day, which is worth understanding before you go solar.
| Factor | Time-of-Use (TOU) | Tiered | Ultra-Low Overnight (ULO) |
|---|---|---|---|
| Lowest rate | 9.8¢/kWh (overnight/weekends) | 12.0¢/kWh (first 600 kWh/mo) | 3.9¢/kWh (overnight) |
| Highest rate | 20.3¢/kWh (weekday 11am–5pm, summer) | 14.2¢/kWh (above 600 kWh/mo) | 39.1¢/kWh (weekday 4–9pm) |
| Best fit for solar | Good — most production happens in mid-peak/off-peak hours | Neutral — no time-shifting benefit either way | Best with a battery — shift evening on-peak use to cheap overnight rates |
| Set by | Ontario Energy Board (OEB) — identical province-wide; only Toronto Hydro’s fixed delivery charge differs by utility | ||
| Switching | Free, once per 12 months, via your Toronto Hydro online account | ||
Not sure which rate plan you’re on? Check your electricity bill — Toronto Hydro lists your plan name in the charges section, and you can switch between TOU, Tiered, and ULO once every 12 months for free through your online account. Most Toronto homes default to Time-of-Use unless they’ve opted into Tiered or ULO.
One Toronto-specific catch worth knowing: Ontario’s Home Renovation Savings rebate and net metering generally can’t be combined on the same solar system — you typically choose one path or the other, so it’s worth having your installer model both scenarios against your actual usage before you commit.

How Toronto Compares to Other Canadian Cities for Solar
Solar panels Toronto homeowners install face real trade-offs compared to sunnier, lower-tax provinces — but Toronto makes up ground with strong installer competition, the City’s own HELP financing program, and Ontario’s 1:1 net metering. Here’s how it stacks up against other major Canadian cities.
| City | Sun hrs/yr | Cost/watt | Electricity rate | Net metering | Tax on solar | Payback (10 kW) |
|---|---|---|---|---|---|---|
| ★ Toronto, ON | 2,066 | $2.80–$3.40 | 9.8–20.3¢/kWh (TOU) | Retail rate | HST (13%) | 8–12 yrs |
| Calgary, AB | 2,396 | $2.70–$3.20 | 12.06¢/kWh | Retail rate | GST only (5%) | 8–10 yrs |
| Edmonton, AB | 2,299 | $2.70–$3.20 | 16–20¢/kWh | Retail rate | GST only (5%) | 9–11 yrs |
| Vancouver, BC | 1,938 | $2.90–$3.50 | 10–15¢/kWh | ~10¢/kWh | PST exempt | 13–17 yrs |
| Halifax, NS | 1,850 | $3.00–$3.60 | ~19.1¢/kWh | Retail rate | HST (15%) | 10–13 yrs |
Toronto trails Calgary and Edmonton on sunshine hours and pays 13% HST versus their 5% GST-only rate — genuinely tougher starting economics. What narrows the gap: Toronto’s large, competitive installer market keeps quoted prices honest, the City-run HELP loan offers financing most other Canadian cities don’t have access to, and Toronto Hydro’s net metering credits exports at the full retail rate. Net result: a market that rewards shopping around more than most.
Questions Torontonians Ask About Solar
Is solar worth it in Toronto?
Yes — with caveats. Toronto gets 2,066 annual sunshine hours and produces less per kW than Calgary or Edmonton, and Ontario charges 13% HST with no sales-tax break. What offsets that: Toronto Hydro’s 1:1 net metering, the $5,000 Home Renovation Savings rebate, and the City’s 4.75% HELP loan. Most homeowners see payback in 7-12 years followed by 15-20 years of low-cost electricity. A properly sized 10 kW system typically saves $900-$1,500 per year depending on your rate plan.
How much does it cost to install solar panels in Toronto?
Solar panel installation in Toronto costs $2.80-$3.40 per watt. For a typical home that’s $22,400-$27,200 for an 8 kW system or $28,000-$34,000 for a 10 kW system before incentives. Ontario’s Home Renovation Savings rebate takes up to $5,000 off that total, and the City of Toronto’s HELP loan lets you spread the remaining cost over 20 years through your property tax bill with no money down.
Does Ontario have a solar rebate in 2026?
The federal Greener Homes Grant (closed March 2024) and Greener Homes Loan (closed October 2025) are no longer available. Ontario’s main program in 2026 is the Home Renovation Savings (HRS) program — up to $5,000 for solar and up to $5,000 more for battery storage, $10,000 combined, on a first-come basis. Toronto also offers the HELP loan for property-tax-based financing, though Ontario charges 13% HST on solar equipment with no sales-tax exemption.
How many solar panels do I need in Toronto?
Most Toronto homes use 8,000-10,000 kWh per year and need a 7-9 kW system — roughly 17-22 panels at 400-450W each. Toronto’s irradiance means each kW produces about 1,150-1,200 kWh annually. South-facing roofs at 30-40° achieve peak output; southeast and southwest still produce 90-95% of that. Use our free solar calculator for a personalised estimate.
9. Frequently Asked Questions
Do solar panels work effectively in Toronto's winters?
Yes. Cold weather actually helps panel efficiency, and Toronto gets meaningful winter production on clear days — snow slides off most modern racking within a day or two, and reflected light off snow can briefly boost output. The bigger swing factor is cloud cover, not cold: Toronto panels typically generate 20–28% of their annual output during the November–February stretch.
Is the Canada Greener Homes Grant still available in Toronto?
No. The federal Greener Homes Grant closed to new applicants on March 31, 2024, and the companion Greener Homes Loan closed in October 2025. Toronto homeowners going solar in 2026 rely on the IESO’s Home Renovation Savings program (up to $5,000 for solar) and the City of Toronto’s HELP loan instead.
How much will solar panels increase my Toronto home's value?
Studies on comparable markets put the bump at roughly 3–4% of assessed value for an owned (non-leased) system — on a $900,000 Toronto home, that’s in the neighbourhood of $27,000–$36,000. Ontario does not reassess your property tax based on adding solar, so the value gain isn’t offset by a higher tax bill.
Do I need a battery with my Toronto solar system?
Most homeowners don’t strictly need one. Ontario’s net metering credits excess daytime production at the full retail rate, so a correctly sized grid-tied system captures most of the financial benefit without storage. Batteries make the most sense if you’re on Ultra-Low Overnight pricing and want to shift more of your own daytime solar into evening on-peak hours, or if backup power during outages matters to you.
How long do solar panels last in Toronto's climate?
25–30 years is standard, with most manufacturers warrantying 80–85% of original output at the 25-year mark. Toronto’s climate — humid summers, freeze-thaw winters — is within the range panels are designed and certified for; it’s not a harsher environment for equipment than most of southern Ontario.
What size solar system do I need for my Toronto home?
A typical Toronto home uses roughly 8,000–10,000 kWh a year, which a 7–9 kW system covers at Toronto’s 1,172 kWh/kW production rate. Roof size and orientation usually matter more than usage alone — use our free solar calculator for a sizing estimate based on your actual roof.
How long does solar installation take in Toronto?
Budget 8–14 weeks from signed contract to activation. Physical installation is 1–2 days; the rest is ESA electrical permitting and Toronto Hydro’s interconnection and net metering application, which is the part most likely to run long if paperwork is incomplete.
What are the best solar panel brands for a Toronto climate?
Canadian Solar, REC, Q Cells, and LG (for older installs still under warranty) are common, reliable choices installed across southern Ontario. Look for panels rated for high snow and wind loads and a manufacturer with a Canadian service presence — warranty claims are simpler when the manufacturer has local support.
Is solar worth it in Toronto in 2026?
Generally yes, though the math is tighter than in sunnier provinces. Toronto gets 2,066 hours of bright sunshine a year and 1,172 kWh/kW of production — noticeably less than Calgary or Vancouver — and Ontario charges 13% HST on top of equipment with no Alberta-style sales tax break. What works in Toronto’s favour: Toronto Hydro’s 1:1 net metering, the $5,000 HRS rebate, and the City’s HELP loan, which together bring most homeowners to a 7–12 year payback.
Does Ontario have a solar rebate in 2026?
Yes — the IESO’s Home Renovation Savings (HRS) program offers up to $5,000 for solar and up to $5,000 for battery storage, $10,000 combined, on a first-come basis. One important catch: HRS funding generally can’t be combined with net metering on the same system, so an installer needs to model both paths against your actual usage before you commit to either.
How many solar panels do I need for my Toronto home?
Most Toronto homes need a 7–9 kW system, which works out to roughly 17–22 panels at common 400–450W ratings, to offset 80–100% of a typical 8,000–10,000 kWh annual bill. Roof shading from mature trees is a bigger factor in older Toronto neighbourhoods than it is in newer suburbs — get a site assessment before assuming a number.
What is the best solar company in Toronto?
There’s no single best answer — SolarGuide tracks 14 installers with a genuine GTA presence, led by Solar X (4.5★, 667 Google reviews) and Polaron Energy (4.6★, 519 reviews) by review volume. Review count is a starting filter, not proof of quality on its own; confirm ECRA/ESA licensing and ask for references from installs in your specific neighbourhood before signing.
