Commercial Solar ROI in Quebec: How Much Can Your Business Really Save?
Installation cost, the 30% federal Clean Technology Investment Tax Credit, accelerated depreciation and Hydro-Québec's OSE program: how to calculate the real ROI of a commercial solar project in Quebec, with a worked example.
Investing in a commercial solar system is far more than an environmental commitment. For Quebec businesses that own their buildings, it's a strategic financial decision that generates real, measurable savings year after year. But what does an installation actually cost? How long before it pays for itself? And which incentives help offset the upfront investment? Here's everything you need to know to calculate your commercial solar return on investment (ROI).
Commercial solar return on investment in Québec: how much can you really save?
How much does a commercial solar installation cost in Quebec?
The cost of a commercial photovoltaic system depends on installed capacity, roof complexity, and equipment choices. As a general benchmark:
- Small system (50 to 150 kWp): between $80,000 and $250,000 before incentives
- Mid-size system (150 to 500 kWp): between $250,000 and $700,000 before incentives
- Large system (500 kWp and up): starting at $700,000, depending on configuration
These figures include panels, inverters, mounting structure, wiring, installation labour, and commissioning. AL Pro Solutions also integrates a structural roof assessment into every project to confirm compatibility. That's a key advantage of our integrated roofing and solar approach.
Financial incentives that reduce your upfront investment
Both the federal government and Quebec offer programs that significantly reduce the net cost of your solar project:
1. Clean Technology Investment Tax Credit (CT ITC): 30%
The federal government provides a non-refundable investment tax credit of 30% on the eligible cost of your commercial solar system. On a $500,000 installation, that's $150,000 in tax credits, an immediate and substantial reduction of your tax liability.
2. Accelerated Capital Cost Allowance: CCA Classes 43.1 and 43.2
Your solar equipment qualifies for CCA Classes 43.1 or 43.2, allowing an accelerated tax deduction of up to 100% in the first year in certain cases. This improves cash flow starting in the fiscal year of installation.
3. Hydro-Québec OSE 6.0 program
The Option Solaire Évolué (OSE) program from Hydro-Québec allows eligible businesses to sell surplus energy back to the grid at a preferential rate, generating additional revenue and improving the overall project ROI.
How to calculate the ROI of a commercial solar project
Your solar return on investment is calculated by comparing the net project cost (after incentives) to the annual savings generated. Here is the simplified formula:
Payback period (years) = Net project cost ÷ Annual savings
Concrete example: industrial building, 250 kWp system
- Gross installation cost: $400,000
- Federal CT ITC (30%): – $120,000
- Estimated net cost: $280,000
- Estimated annual production: 290,000 kWh
- Annual savings (average Hydro-Québec rate): about $34,000
- Estimated payback period: roughly 8 to 9 years
- System lifespan: 25 to 30 years
In this example, the business generates 15 to 20 years of net profit after full payback. A return that very few investments can match at this level of risk.
Key factors that influence your solar ROI
Every project is unique. Several variables will affect your specific return on investment:
- Roof orientation and slope: a south-facing roof with a 10 to 30° pitch maximizes solar production in Quebec.
- Roof membrane condition: a roof nearing end of life will require work before installation. AL Pro Solutions integrates this assessment from day one.
- Your electricity consumption: the higher your Hydro-Québec bill, the greater your potential savings.
- Shading: trees, mechanical equipment, or adjacent rooftops can reduce production.
- Rising electricity rates: as Hydro-Québec rates increase over time, your future savings grow proportionally.
