Making the numbers work for a residential energy storage system
Michelle Davis from WoodMac Renewables & Power said that 7% of residential solar capacity was paired with storage in 2020. She said that growth rate is on track to more than double in 2021, to 16%. Anecdotal evidence in "hot markets" suggests this value could be closer to 60% if batteries were available.

Overview. The Home Energy Model (HEM) storage tank model is a 4-layer tank model based on Method A from BS EN 15316-5:2017. Hot water is drawn off from the top of the tank and replaced by fresh cold water at the bottom which is then heated in the tank by one or more heat sources. It is assumed that the water is stratified by temperature.

How Long Can You Run Your House on a Tesla Powerwall?
Usable storage capacity is listed in kilowatt-hours (kWh) since it represents using a certain amount of electricity (kW) over a certain amount of time (hours). Tesla Powerwall usable storage capacity = 13.5 kWh. Functionally, this means you can use either 13.5 kW for 1 hour, 1 kW for 13.5 hours, or something in between.
