How do you calculate battery efficiency?
Efficiency is the sum of energy discharged from the battery divided by sum of energy charged into the battery (i.e., kWh in/kWh out). This must be summed over a time duration of many cycles so that initial and final states of charge become less important in the calculation of the value.
How is energy storage life determined?
The energy storage life is also determined by the actual operation strategy of energy storage; and in order to determine the operation strategy of energy storage, the configuration capacity of photovoltaic and energy storage must be given first.
Why do energy storage systems need to be rated?
