And I'm saying how much energy you use 'per day' is vague when you're talking about it wrt your energy generation. If you have 30kW solar and no battery then 'all my usage is during peak sun' and 'all my usage is over a split second at 1am' and 'my usage is uniform across 24h', etc. are all very different even if all amount to 30kWh usage 'per day'.
