Three performance parameters may be used to define the performance of grid-connected PV systems: final PV system yield Yf, reference yield Yr, and performance ratio PR. The Yf and PR are determined using the nameplate d.c. power rating. The Yf is the primary measure of performance and is expressed in units of kWh/kW.
Four performance parameters that define the overall system performance with respect to the energy production, solar resource, and overall effect of system losses are the following: final PV system yield, reference yield, performance ratio, and PVUSA rating.
PV system specifications were the same as the PV system located on the roof of the Solar Energy Research Facility (SERF) at the National Renewable Energy Laboratory (NREL): single-crystalline silicon PV modules, nameplate d.c. power rating of 7420 W, PV array tilt angle of 45°, and PV array azimuth angle of 22° east of south.
Thus, the presence of the battery would always be beneficial if the average price of electricity corresponding to the chosen configuration is lower than the average purchase price of electricity from the network. Optimal Sizing is the common and only solution to overcome the disadvantages and high costs of PV Battery Systems. 3.2. Case Study
