Impact of Defective Modules on the Characteristics of a Large-Scale Grid-Connected PV Power Plant

Popis výsledku v původním jazyce

The effect of the connection of different, shaded or damaged module on the performance of the whole string or the photovoltaic (PV) panel connected to a single inverter is very often discussed. Although there exist the means for protecting the PV system against negative influence of connecting PV modules with different parameters into one system (diodes, power optimizers), the real impact is not examined anymore. The simulation tools presume the connection of the same module type with same parameters and the differences are discussed only theoretically. The simulations performed in the SPICE program rather indicate that with less damage, one different module should not have a significant effect on the power drop, even in the theoretical case that no bypass diode is included in the string. The results of simulation as well as the measurement on the real system with modules with different parameters are presented in this work.
