This paper investigates the energy losses introduced by Maximum Power Point Tracking operation of photovoltaic (PV) inverter. In contrast to other studies, this evaluation has been done with the recorded real-life solar irradiance data applied to the simulation of the PV-generator and tracking algorithm. The true MPP output of photovoltaic generator has been calculated with electro-thermal model and the simulation has been carried out with 1 s time resolution. The efficiency results have been presented for both static and dynamic MPP-tracking investigated With basic and simplified Perturb&Observe algorithm with several tracking speed rates. In addition to the simulation, the inverter efficiency measurements for field- installed inverter have been presented.
