This. Energy can take many forms. You don't have to store all in a battery.
Another idea: assuming you have an electric water heater, when your battery has been fully charged and you still have excess generation, use the excess to heat your water heater up to a very high temperature like 80 degrees C. You'll then be using very little hot water in the evening for showers and dishwashers, etc, and the water heater basically won't need to turn on at all.
