Try to figure out how many kWh of electricity per day this system will need. If it needs lets say 10 kWh/day; you will need a solar system that produces that. Here is the equation you can use: Solar System Size = kWh/day Needed / (Peak Sun Hours * 0.75). Quick Example: Let''s say you need 10 kWh/day and live in location with 5 peak sun hours.
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.
