Solar Calculator Quebec

Yes. Hydro-Québec's self-generation program allows residential customers to connect solar systems and receive credits for surplus generation. Credits are applied to future bills at the retail rate. The program caps system size so annual generation does not exceed annual consumption. Any remaining credit at year-end is paid out at a rate determined by Hydro-Québec.

Quebec has some of Canada's lowest electricity rates (around 7–9¢/kWh), which means longer payback periods (typically 16–20 years without incentives). However, the federal 30% Clean Technology Investment Tax Credit dramatically improves the math—reducing a $21,000 system to $14,700 net cost. With annual rate increases of 3–5%, the long-term case strengthens each year. Solar is more a 25-year hedge against future rate increases than an immediate win.

Hydro-Québec uses a two-tier "Rate D" structure. The first 30 kWh/day (~900 kWh/month) is charged at approximately 6.24¢/kWh (Tier 1). Usage above that threshold is charged at approximately 9.39¢/kWh (Tier 2). These rates are among the lowest in North America, making Quebec solar economics unique compared to other provinces.

Quebec residents can access the federal 30% Clean Technology Investment Tax Credit on eligible solar systems. The provincial government has not maintained a direct residential solar rebate program, but Hydro-Québec's net metering program provides ongoing value. Some municipalities offer supplementary green energy grants—check with your city. Always verify current programs as they evolve.

A typical 7 kW residential solar system in Quebec costs $18,000–$24,000 before incentives. After the federal 30% ITC, net cost drops to $12,600–$16,800. Prices are similar to Ontario and BC, though installer availability varies by region. Montreal and its suburbs have the best installer competition and typically the most competitive quotes.

Absolutely. Montreal averages approximately 2,050 peak sun hours per year—comparable to parts of Germany and France, which have thriving solar markets. Quebec City averages around 1,950 hours. Winter months produce less, but summer surpluses more than compensate when modelled annually. Modern panels handle cold Quebec winters well and snow typically slides off tilted arrays within days.

With Hydro-Québec's low rates, payback without incentives is 18–22 years. After the federal 30% ITC, that drops to roughly 14–18 years. As Hydro-Québec rates increase (historically 3–5%/year), payback improves year-over-year. Many Quebecers view solar as a long-term inflation hedge on their electricity bill rather than a short-term investment.

Yes. The federal 30% Clean Technology Investment Tax Credit reduces your upfront cost, while Hydro-Québec net metering generates ongoing bill credits. These are two separate mechanisms—one reduces capital cost, the other generates ongoing savings. You can take full advantage of both simultaneously.
