A rooftop solar quote in Canada rarely arrives as a single number. Installers may offer to sell you the system outright, finance it through a green loan, or place panels on your roof under a lease or power-purchase agreement where a third party owns the hardware. The monthly payment looks attractive; the twenty-year math often tells a different story.
This guide compares lease versus purchase for residential solar with examples from Ontario, Alberta, and British Columbia — the provinces where most Canadian homeowners are evaluating arrays in 2026.
Three ways Canadians pay for rooftop solar
Cash or financed purchase: You own the panels, inverter, and racking. You claim any eligible rebates, receive export credits or net-metering value directly, and carry maintenance responsibility after the installer warranty ends.
Solar lease: A company installs and owns the system on your roof. You pay a fixed monthly lease fee for a set term — often 20 years — in exchange for using the electricity the array produces.
Power-purchase agreement (PPA): Similar to a lease, but you pay per kilowatt-hour generated rather than a flat monthly fee. PPAs are less common in Canada than in the United States but appear in some markets.
Upfront cost: where leasing wins on paper
A typical 8 kW residential system in Ontario might cost $24,000–$30,000 before incentives. In Alberta and BC, pricing varies with labour markets and permitting, but the range is comparable. Leasing eliminates that lump sum: many offers require little or no money down.
For households without home-equity access or green-loan eligibility, leasing can be the only way to go solar immediately. The trade-off is that someone else captures the long-term upside — export credits, increased home value, and decades of free electricity after payback.
Lifetime savings: where ownership usually wins
Ownership economics depend on three variables: installed cost net of rebates, annual production, and the value of offset retail electricity. A well-sited 8 kW system in southern Ontario might produce 9,000–10,000 kWh per year. At a blended retail rate of $0.13–$0.17/kWh, that is $1,200–$1,700 in annual bill offset before export nuances.
Simple payback on a purchased system often falls between 10 and 16 years depending on province and self-consumption. After payback, production is essentially free electricity for the remaining module life — typically 25–30 years.
Lease payments, by contrast, are contractual obligations that do not shrink when your usage drops or when you move. Escalator clauses — annual payment increases of 2–3% — are common and can erode savings in later contract years.
Who owns the rebates and export credits?
Provincial and utility incentives generally flow to the system owner. Under a lease, the leasing company typically retains eligibility for any production-based credits and may pass only a portion of savings to you through a lower lease rate.
In Ontario, net-metering credits accrue to the account holder with a bi-directional meter. If the lessor holds the generation account, credit mechanics become more complex and may not transfer cleanly if you switch retailers.
In Alberta's competitive retail market, micro-generation export terms are tied to your retailer contract. A leased system may require the lessor to be party to billing arrangements — read contracts carefully before signing.
Maintenance, monitoring, and warranty
Leasing companies often bundle monitoring and inverter replacement during the contract term. That is genuine value: inverter lifespans of 10–15 years mean purchased systems may face a $2,000–$4,000 replacement mid-life.
However, purchased systems from reputable installers include 10–25 year equipment warranties and 2–10 year workmanship coverage. Factor warranty terms into your comparison rather than assuming leased systems are the only low-maintenance option.
How the math differs by province
Ontario: Net metering allows credit rollover within a 12-month period on most utility bills. High self-consumption under time-of-use rates improves ownership economics. Leasing is less prevalent than in the US but available through national providers.
Alberta: Export value depends on your retailer's micro-generation tariff. Ownership lets you shop for solar-friendly retailers annually. Lease contracts may lock you into specific billing arrangements.
BC: BC Hydro net metering and regional rebates (where available) favour ownership. Lease products exist but provincial policy emphasis has been on customer-owned distributed generation.
Quebec: Hydro-Québec's net metering program and historically lower electricity rates mean payback periods are longer. Leasing offers are limited; verify any third-party contract against Hydro-Québec interconnection rules.
A side-by-side example: 8 kW system in the GTA
Consider a Toronto-area home with a $27,000 purchase price, $0 down financing at 6.5% over 15 years, versus a 20-year lease at $120/month with a 2.5% annual escalator.
| Factor | Purchase (financed) | 20-year lease |
|---|---|---|
| Year 1 out-of-pocket | ~$2,800 loan payments | $1,440 lease payments |
| Year 10 cumulative cost | ~$28,000 (loan nearly paid) | ~$16,500 (escalators add up) |
| Year 20 cumulative cost | ~$28,000 total, then free power | ~$37,000+, system not yours |
| Home resale | Owned asset transfers with sale | Buyer must assume or buy out lease |
| Rebates / tax benefits | Homeowner retains | Typically lessor retains |
Numbers are illustrative. Your quote will differ — but the pattern holds: leasing smooths early cash flow; ownership concentrates savings in years 12 through 25.
Questions to ask before choosing lease or purchase
- What is the total cost of the lease over the full term including escalators?
- Can I buy out the system early, and at what price?
- Who holds the net-metering or micro-generation account?
- What happens to the contract if I sell my home?
- Does the lease company carry liability insurance for roof penetration damage?
- Are production guarantees enforceable, and who monitors output?
When leasing makes sense
Leasing can be reasonable if you plan to stay in the home for the full contract term, have no access to low-cost financing, and the lessor offers a buyout option you can exercise before a sale. It is harder to justify if you expect to move within five to seven years, if you qualify for provincial rebates only available to owners, or if your roof has less than 15 years of remaining life.
Most Canadian homeowners who treat solar as a long-term investment still come out ahead by purchasing — with cash, a Canada Greener Homes Loan where eligible, or a bank green renovation line. Run both scenarios on identical production assumptions before you sign.
