Quebec Commercial Solar Grants

Hydro-Québec offers a business solar grant for qualifying commercial self-generation projects — up to $1,000 per kilowatt installed and up to 40% of eligible project costs, subject to program caps and current terms. It is one of the strongest provincial commercial solar supports in Canada in 2026.

Yes. Quebec commercial projects stack the federal Clean Technology ITC (up to 30% refundable on eligible capital costs) on top of the Hydro-Québec business grant. Together, these supports can materially reduce net project cost for eligible commercial installations.

Typical documentation includes site drawings, structural engineering, single-line electrical diagrams, equipment specifications, an interconnection application, cost estimates, and expected production modeling. Program-specific requirements change — verify the current checklist on Hydro-Québec's business energy program pages before assembling your submission.

Quebec commercial solar is designed within Hydro-Québec's self-generation framework, which sets rules for interconnection, export treatment, and system size relative to on-site load. Proper sizing avoids exceeding program caps while maximizing self-consumption value — an experienced Quebec commercial installer will model this into their proposal.

Quebec commercial solar typically runs $1.80–$2.50 per installed watt in 2026, before incentives. A 100 kW rooftop system usually lands in the $180,000–$250,000 range before Hydro-Québec grant support and the federal Clean Tech ITC. Stacked support can bring net cost down significantly on eligible projects.

Payback varies with grant treatment. For projects that fully leverage the Hydro-Québec business grant and federal Clean Tech ITC, Quebec commercial solar can achieve payback in the 6–9 year range — sometimes shorter for facilities with strong daytime load and high electricity consumption. Actual results depend on system design, site conditions, and finalized incentive amounts.
