Turn Ontario's Lowest Electricity Rates Into Long-Term Savings
Power your home smarter with solar and battery storage from Stardust Solar
Toronto homeowners now have a unique opportunity to reduce electricity costs, improve energy resilience, and take advantage of financing programs designed to make solar and battery installation more affordable than ever.
With Ontario's Ultra-Low Overnight (ULO) electricity rate, homeowners can charge a battery overnight at some of the lowest electricity prices available and use that stored energy during expensive peak-rate periods. When paired with solar, battery storage can help maximize self-consumption and reduce reliance on the grid.
