The Quebec City commercial solar market
Quebec City commercial solar follows Montreal's economics — low retail rate requires demand-charge reduction + Solutions efficaces + federal ITC to produce acceptable payback. Quebec City's cooler climate reduces summer cooling-load demand-charges modestly vs Montreal, which weakens demand-charge-shaving math somewhat. Payback typically 1-2 years longer than Montreal for comparable systems.
