A solar system that includes solar batteries is known as a solar-plus-storage system. These systems are becoming increasingly popular amongst residential homeowners’, due to their energy efficiency storage capabilities. However, additional solar batteries or solar-plus-storage is not a requirement for most solar homeowners in Ontario because of existing net-metering program that is made available to solar homeowners. So long as your solar system is connected to the utility grid with the net-metering program, your system does not require a battery or solar-plus-storage system. The utility company essentially acts as your own batter for a modest connection fee of about $30 per month. Considering all excess power that is generated by your solar panel system, is directed back into the utility grid, which at no additional cost you can get back as a credit if your home requires more electricity than your panels can generate at any time in the day.
