PV system performance has strongly improved. Before year 2000 the typical Performance Ratio was about 70%, while today it is in the range of 80% to 90%. Often residential and small commercial PV systems are installed with a battery storage and a charging station for electric mobility.
The final step in modeling the performance of a PV system is to account for any AC losses be-tween the inverter and the final revenue meter that determines how much AC electricity is avail-able. For small systems (e.g., residential) the meter is directly adjacent to the inverter and AC losses are negligible.
