Combined Solar PV System with Energy Storage and Late-Night Recharging
As a result of new very-low overnight electricity rates (2.4 cents per KWh) in Ontario, reduced costs of solar PV modules and energy storage and the new 30% federal tax credit for this type of equipment, homeowners and businesses can save considerable money by installing a solar system with battery-based energy storage. Shown below is short slideshow that includes a simplified schematic of this arrangement along with a simple graph that illustrates how you can make use of this battery twice a day.

• The new optional Ultra-Low Overnight price plan provides:
• Ultra-low overnight rate of 2.4 cents per kWh: everyday 11 p.m.-7 a.m.
• Mid-peak rates of 10.2 cents per kWh: weekdays 7 a.m.-4 p.m. and 9 p.m.-11 p.m.
• On-peak rates of 24.0 cents per kWh: weekdays 4 p.m.-9 p.m.
• Weekend off-peak rates of 7.4 cents per kWh: weekends and statutory holidays 7 a.m.-11 p.m.
