Quick question for the people living in the US (Target customers of the Powerwall). What is your yearly power usage?
On the website[0] they put for sizing 10kWh/day/BR. Which means 14600kWh/year for a 4 bedroom house. Here in Germany, working from home with a 4BR+office house, we are using 2550kWh/year. So, I suppose the Tesla sizing is to support a "peak day" usage, but still, I am surprised by the calculations. This is why this totally informal and unscientific survey :)
