Does this new product make sense in Ontario for people who are on the grid? I have looked into the Microfit program which allows you to install solar panels up to 10kW on your home and sell the power back into the grid for $0.384/kWh for twenty years. Given that is about 3-4X what you pay for power it makes no sense to use this power yourself. Therefore I don't see why you would want to store power that you generate from solar panels, unless you are off grid. Or would the PowerWall make sense as a backup source of power instead of a generator? This may change in the future as I believe the Microfit program is moving to net metering.
