Cost of Installing Solar Panels in Canada: What You'll Actually Pay in 2026

Installing solar panels in Canada costs $2.50 to $3.50 per watt for monocrystalline panels, the most common residential choice. A typical 5 to 10 kW home system runs roughly $12,500 to $35,000 fully installed, covering panels, inverter, labour, and permits.

Ontario sits at the affordable end of that range at $2.42 to $3.50 per watt, thanks to a competitive installer market. The province also runs the largest residential solar rebate in the country right now, worth up to $5,000, though claiming it means giving up net metering. That trade-off is covered below.

P.S. If you're an Ontario homeowner with equity and you're wondering how to pay for an installation, Lotly's secured home loans are worth a look. All credit scores and income types accepted.

How much do solar panels cost by system size?

System size, measured in kilowatts, drives your total cost more than any other variable. Larger systems cost more overall but less per watt, because fixed costs like permits, scaffolding, and the electrician's mobilization get spread across more capacity.

Most Canadian homes run on 5 to 10 kW. The Ontario Energy Board puts average household consumption at roughly 9,000 kWh per year, which lands most homes around 7.5 kW.

These are fully installed, pre-incentive figures. If you're pricing 12 panels, that's roughly 4.8 kW, or $12,000 to $16,800.

One Ontario-specific note: the province is raising the residential micro-generation inverter cap from 10 kW to 12 kW AC, which gives larger homes more headroom than they had previously.

What's included in the installation cost?

Equipment accounts for 60 to 70% of your budget: panels, inverter, mounting and racking hardware, and all the wiring and electrical components. String inverters run $1,000 to $2,000; microinverters cost $2,000 to $4,000 or more but handle shading better. Battery storage is optional and adds $8,000 to $15,000.

Labour is another 15 to 25%. Ontario requires solar installers to be certified electricians. Most residential installs take one to three days once equipment arrives, longer if your roof needs flashing work or structural reinforcement.

The remaining 10 to 15% covers municipal building permits, the mandatory Electrical Safety Authority inspection for grid-tied systems, net metering application fees, and engineering and design work that some installers bill separately.

How do panel types compare on cost?

Panel type affects both your upfront price and how much electricity you generate over 25 years. Cheaper panels need more roof space to hit the same output.

Monocrystalline is the default for most Canadian homes because the higher efficiency matters more in a country with shorter winter daylight hours.

Installers quote by watt rather than square footage, so cost per square foot isn't a figure you'll see on a quote. For reference, a 400W monocrystalline panel covers about 20 square feet and costs $960 to $1,400 installed, working out to roughly $48 to $70 per square foot.

What solar rebates are available in Ontario?

Ontario's Home Renovation Savings Program is currently the largest residential solar incentive in Canada. It pays $1,000 per kW (up to $5,000) for solar, plus $300 per kWh (up to $5,000) for paired battery storage. The program is delivered by Save on Energy and Enbridge Gas with Ontario government support, and it replaced the older HER+ program in January 2025.

Three things determine whether you actually get the money:

Pre-approval is mandatory. Applications must be approved before installation begins. Retroactive applications get rejected, which is the single most common reason homeowners miss out.

You have to choose between the rebate and net metering. Systems claiming the HRS solar rebate must be sized for load displacement only, with zero export to the grid. Net metering credits your surplus generation at retail rates but disqualifies you from the rebate. Households with high daytime consumption and modest evening use generally do better on net metering. Households that mostly self-consume tend to come out ahead with the rebate. Run both against your actual hydro bill before deciding.

Funding is first-come, first-served. The program runs on a year-by-year budget and has a reported funding window through late 2026, though it can close earlier if the budget runs out.

Toronto homeowners have a second option: the Home Energy Loan Program offers up to $125,000 in low-interest financing repaid through your property tax bill over 5 to 20 years, with no credit check. Ottawa runs a comparable program. HELP financing isn't compatible with the HRS rebate, so you pick one.

What about federal solar incentives?

The federal residential picture is thinner than it was two years ago. The Canada Greener Homes Grant, which paid up to $5,000, closed to new applicants in February 2024. The interest-free Canada Greener Homes Loan of up to $40,000 stopped accepting applications on October 1, 2025. Existing borrowers continue under their original terms.

The replacement is the Canada Greener Homes Affordability Program, an $800 million initiative delivered through the provinces rather than directly by NRCan. It targets low- to median-income households, and whether solar qualifies depends on how your province implements it.

The 30% Clean Technology Investment Tax Credit comes up a lot in solar marketing, but individual homeowners don't qualify. It applies to businesses and commercial installations only.

If you're weighing other upgrades alongside solar, it's worth reviewing grants available to Canadian homeowners for a fuller picture of what applies to your situation.

How much does solar cost across Canada?

Atlantic provinces run higher because installer capacity per capita is lower. Alberta runs lower because of a competitive, deregulated market.

What else affects your final quote?

Roof condition tops the list. If yours needs replacement before you install panels, add $5,000 to $15,000. Orientation matters too: south-facing roofs at 30 to 45 degrees produce the most energy, and other orientations need more panels for the same output.

Shading often forces microinverters instead of a cheaper string inverter, adding $1,000 or more. Older homes sometimes need an electrical panel upgrade first, which can cost $1,500 to $3,000. Ground mounts cost 10 to 20% more than roof mounts, and prices for the same system vary 20 to 30% between installers, so three quotes is the minimum.

If you're budgeting other home renovation costs alongside solar, a single secured home loan can cover multiple scopes of work in one approval.

How do you estimate your own cost?

Four steps get you close enough to decide whether solar makes sense before you start collecting quotes.

Pull your electricity bill and find your monthly kWh consumption. The average Ontario home uses 700 to 1,000 kWh per month, higher if you have an EV or electric heat. Divide your annual kWh by about 1,200, Ontario's solar production factor, to get the system size you need. So 9,600 kWh per year divided by 1,200 gives you an 8 kW system. Multiply that system size in watts by $2.42 to $3.50 to get your Ontario cost range: 8,000W at $3.00 is $24,000 before incentives.

For a refined estimate, Natural Resources Canada's photovoltaic potential tool calculates generation based on your location and roof angle. Most reputable installers also offer free site assessments. Online calculators can't account for your roof condition, shading, or electrical panel, so a professional quote is always the next step.

Why does financing interest matter so much?

Most solar calculators quote the cash price and calculate ROI from that number, even though most homeowners finance. The interest is a real cost that extends your payback period.

On a $20,000 system:

That $3,600 gap is worth roughly two years of free electricity, and it doesn't appear on any panel spec sheet.

Ontario homeowners with equity can usually access lower rates through a secured home loan than through unsecured solar financing or credit cards. For how a HELOC compares to a personal loan on home improvement financing, that guide covers the trade-offs.

What's the payback period on solar in Canada?

Payback typically runs 8 to 15 years nationally. Ontario homeowners generally break even in 7 to 12 years, depending on which incentive path they choose, since the HRS rebate meaningfully shortens payback for homes that qualify.

A worked example: a 7 kW system at $21,000 saving roughly $1,800 a year pays back in about 11.7 years, with 25-year net savings north of $24,000. Claim a $5,000 HRS rebate on that same system and payback drops closer to 9 years.

Rising electricity rates shorten payback. Heavy shading, north-facing roofs, and high-interest financing lengthen it.

Worth budgeting for: your inverter will need replacement once around year 12 to 15, at $1,500 to $3,000. Amortized across 25 years, that's about $100 a year in true ownership cost.

Should you install solar in 2026?

Solar works well if you own your home and plan to stay 10 or more years, your roof is south or southwest-facing and in decent condition, and you can finance at a reasonable rate.

It works less well if you rent or plan to sell soon, your roof has significant shading, your roof needs replacing in the near term, or you're financing at a rate that pushes payback past 15 years.

On that last roof point: if yours is more than 15 years old, installing panels first is an expensive sequencing error. When the roof eventually needs work, you'll pay $1,500 to $3,000 to remove and reinstall the panels, and no installer's quote includes that. Under 10 years, proceed. Between 10 and 15, get an inspection first. After 15 years, budget both projects together, which often costs less overall because labour, scaffolding, and mobilization are shared.

Panel costs have dropped roughly 70% over the past decade, though that decline has flattened out. Electricity rates keep climbing. A 7 kW system offsets around 5 to 7 tonnes of CO₂ annually, and research suggests solar can add 3 to 4% to a home's resale value.

How can Lotly help fund your solar installation?

For Ontario homeowners with equity, a secured home loan is usually the cheapest way to fund an installation, and approval doesn't depend on your credit score. Lotly covers $10,000 to $1,000,000, accepts all credit scores and income types, including self-employed and gig income, and funds in about two weeks.

Three things to take away:

• Check the HRS rebate before you finance anything. Up to $5,000 for solar and $5,000 for battery storage changes your total borrowing need substantially. Get pre-approved before installation begins, and model the rebate against net metering using your actual hydro bill, since you can't have both.
• Your interest rate matters as much as your panel choice. The difference between 8% unsecured and 5% secured on a $20,000 system is about $3,600 over ten years, which shortens your payback by roughly two years.
• Bundle the roof if it's aging, and the debt if you're carrying it. A single secured home loan can cover a roof replacement and a solar install together at a lower blended rate than financing each separately. The same applies to high-interest balances: rolling existing debt into the same loan gives you one payment and lower hydro bills at once.

Frequently asked questions

How much does it cost to install solar panels in Ontario?

$2.42 to $3.50 per watt installed, putting a standard 5 kW system between $12,100 and $17,500 before incentives. That covers panels, inverter, mounting hardware, labour, ESA inspection, and permits. HST applies to the full installation cost.

Is there a solar rebate in Ontario?

Yes. The Home Renovation Savings Program pays $1,000 per kW (up to $5,000) for solar, plus $300 per kWh (up to $5,000) for battery storage. You must get pre-approval before installation, and accepting the rebate makes you ineligible for net metering.

How many solar panels does a typical Canadian home need?

Most homes run on 5 to 10 kW. A 5 kW system uses 13 to 16 panels; 10 kW uses 26 to 32. Divide your annual kWh by 1,200 to estimate the capacity you need.

What's the payback period for solar panels in Canada?

Eight to 15 years nationally, and 7 to 12 in Ontario depending on your incentive path. After that the system generates essentially free electricity for another decade or more.

Are the federal solar grants still available?

No. The Canada Greener Homes Grant closed in February 2024 and the Greener Homes Loan closed October 1, 2025. The replacement Canada Greener Homes Affordability Program targets low- to median-income households and is delivered through the provinces. The 30% Clean Technology ITC applies to businesses, not homeowners.

Can I use a home equity loan to fund solar?

Yes, and for many Ontario homeowners it's the most cost-effective route. A secured home loan through Lotly gives you $10,000 to $1,000,000 against existing equity, with all credit scores and income types accepted. The lower rate compared to unsecured solar financing can save thousands and shorten your payback period.
