How time-of-use savings shorten payback
Every kilowatt-hour you shift from peak to off-peak earns you the gap between those two rates. On Ontario's Ultra-Low Overnight plan that gap is about 25 cents per kWh. A 13.5 kWh Powerwall cycled once a day captures roughly that spread every cycle, on top of storing your own solar power for the evening instead of exporting it for less. Over a year that arbitrage shortens payback alongside any battery rebates.
- + Charge the battery overnight on cheap off-peak or ultra-low overnight power, or straight from your solar panels.
- + Discharge during expensive on-peak hours so you avoid buying high-priced grid power.
- + Keep a reserve for outages, and let Storm Watch top up the battery before bad weather.
- + The bigger the gap between off-peak and on-peak rates, the more a Powerwall saves.
Rates and time-of-use windows vary by province and utility. Figures are illustrative.
Ontario note: the Home Renovation Savings Program battery rebate requires a no-export system, so it is an either/or with net-metering export. Your installer will model which path saves more for your home.
