kW vs kWh in solar & battery storage | Solar Choice
Hi Edmount, ''Kilowatts peak'' (or kWp) refers to the maximum possible output of the system. For example, a 5kW solar system actually has a ''peak''/nameplate output of 5kW, but in reality it may only reach this peak output when the sun is at its highest point during the day – usually between 11 and 2pm or so. kWp is basically a more specific (and accurate) way to …
Typically, when Superchargers charge at less than 150 kilowatts (kW), they share power supplies between certain stalls – the same numbers share power between their A and B stalls. So, if you pull up to charge at Stall 1A and another Tesla is already charging at 1B, your battery will charge slower than if you were the only car …
