Wow.. In the winter, with the (extremely) cold days that we get I use over 200kWh per day, most of it at night (yes, the shining sun does reduce the load in the day by quite a wide margin with high quality windows). But then the sun is only up for 8 hours and some, and beside it takes an hour out on both sunrise and sunset before it manages to hit the house and lose it early. Not even talking about the bad angle of the sun, it means we would need way too much solar panel to be able to provide for a days worth of energy, and a lot of capacity to store it. And that's not even taking into account that we have a lot of days where we don't get to see the sun at all because of the extremely deep cover.
Lets say we want to be able to provide 3 days of energy without functionning panels (or a bit longer with some energy in), that takes a minimum of 600kwh, or about 95 tesla powerwall units with a 90% efficiency inverter. Where you trolling or do you really think this small battery is a revolution ? Speaking of revolution, I would rather have a large sized flywheel dug somewhere nearby.
