N2 - The study discusses the short-term performance variations of grid-connected photovoltaic (PV) systems
installed in Kanpur, India. The analysis presents a holistic view of the performance variations of three PV array
technologies [multi-crystalline (multi-Si), copper indium gallium diselenide and amorphous silicon] and two inverter
types (high-frequency transformer and low-frequency transformer). The analysis considers the DC–AC conversion
efficiency of the inverter, system performance through performance ratio (PR) calculations, energy variations between
fixed and tracking systems and the comparison between calculated and simulated data for the examined period. The
energy output difference between the tracking and fixed systems of the same PV technology show that these are
dependent on differences in temperature coefficient, shading and other system related issues. The PR analysis shows
the effect of temperature on the multi-Si system. The difference between the simulated and measured values of the
systems was mostly attributed to the irradiance differences. Regarding the inverter evaluation, the results showed that
both inverter types underperformed in terms of the conversion efficiency compared with nameplate values.
