Abstract: Photovoltaic (PV) panels are energy production elements that are directly and catastrophically affected by climatic conditions. In this study, the performances of monocrystalline and polycrystalline photovoltaic panels, which are most commonly used in photovoltaic systems, were experimentally examined in summer and winter seasons. A comparison was made of the factors affecting the electrical performance of PV panels in summer and winter seasons under geographical climatic conditions at Istanbul University—Cerrahpaşa Avcılar center. In this experimental study, monocrystalline and polycrystalline PV panels with a power of 100 W were used. By drawing the characteristic curves of the current–voltage–power parameters, which are the electrical output parameters of the PV panels, seasonal performance comparisons were made comparatively with different weather conditions following the instantaneous effect in Avcilar, Istanbul.
