A more viable option in Ontario than trying to store power in batteries for non-sunlight hours is to sell it to the Ontario Power Authority. If you were to apply for the OPA microFIT program and gained a contract with them (microFIT Program | Ontario Power Authority) you would be able to sell any excess power you generate at a rate of 54.9 cents/kWh (for a rooftop solar installation). If you sell enough electricity during the day to offset the electricity cost of non-sunlight hours then you wouldn't need batteries, cutting out almost half of the installation cost.
