FindSolar.caHydro-Québec's net metering, Option I in the tariff book, is generous machinery with two quiet rules that shape every solar decision in the province: credits are energy, not money, and the bank resets on a 24-month cycle. Understand those two and the rest of Quebec solar design follows; miss them and oversizing quietly donates your surplus at the grid's lowest rate.
How the crediting works
Feed in more than you draw, and the surplus lands in a credit bank measured in kilowatt-hours; draw more than you feed, and banked credits cover the gap before billed consumption does. The rules live on Hydro-Québec's Option I page, verified August 26, 2026. Day to day it behaves like a battery you did not buy: summer afternoons fill it, winter evenings drain it.
The 24-month reset, and what the payout really pays
Every 24 months the bank resets to zero. A positive balance at reset is not lost outright: it is credited to your bill at the average cost of electricity supply, a wholesale-flavoured rate far below what you pay at retail. That gap is the whole design lesson. Credits spent against your own consumption are worth retail; credits paid out at reset are worth a fraction of it. The program forgives seasonal imbalance and punishes chronic overproduction, which is precisely the right way around for homeowners who size correctly.
Sizing an electrically heated Quebec home
Quebec's electric heating gives houses a deep winter consumption valley for summer credits to fill, and the 24-month window is long enough to make that seasonal arbitrage work. The sizing discipline: target your annual consumption, let the credit bank smooth the seasons, and resist the roof-maximizing pitch, because production beyond annual usage rides the bank to the reset and exits at the low rate. The Quebec worth-it guide pairs this with the LogisVert grant math, and the sizing guide covers the general principle.
Practicalities worth two phone calls
Connection runs through Hydro-Québec's self-generation process, application before installation, like every utility in the country. And if your account uses a time-differentiated rate option, ask how crediting interacts with it for your specific tariff, since avoided-cost value follows the rate you are on. Two calls, made early, and the province's generous machinery works exactly as designed, for you.
Questions homeowners ask
How does Hydro-Québec net metering work for a homeowner?
Surplus generation banks as kilowatt-hour credits; when you draw more than you produce, banked credits cover the gap before billed consumption. It functions like seasonal storage you did not pay for, with the rules published on Hydro-Québec's Option I page, verified August 26, 2026.
Can I use summer solar credits against winter heating bills?
Yes, and the 24-month banking window is long enough to make summer-to-winter arbitrage truly work for electrically heated homes. That seasonal fill-and-drain is the program's intended shape; a well-sized Quebec system leans on it every year.
Do unused credits ever get paid out in cash?
At the 24-month reset, a remaining balance is applied to your bill at the average cost of electricity supply, a rate far below retail. It is compensation, not cash, and deliberately modest: the program rewards matching production to your own use, not farming the reset.
How large should I size solar for an electrically heated Quebec home?
Toward your annual consumption, letting the credit bank bridge seasons: winter heating gives summer surplus somewhere valuable to go. Production beyond annual usage rides the bank to the reset and exits at the low payout rate, so the roof-maximizing pitch has a specific, checkable cost in Quebec.
Does Time-of-Use or another rate option change solar value?
Rate structure shapes what avoided consumption is worth, so if your account uses a time-differentiated option, confirm with Hydro-Québec how crediting interacts with your specific tariff before finalizing design. The right person to ask is the utility, with your account number in hand.
What happens if my panels produce more than I consume over the year?
The excess accumulates in the bank and, at the 24-month reset, pays out at average supply cost instead of retail value. One unusual sunny year is forgiven by design; a system built to overproduce every year has chosen the program's worst rate as its business model.
