Performance analysis of polycrystalline and CIS thin-film PV panels in real operation conditions

This paper deals with a comparative analysis carried out on two types of PV panels widely spread on the market: polycrystalline and thin-film (CIS technology). The research was focused on the performance evaluation of the studied PV panels in real operation conditions. In this context the influence of different parameters (temperature, solar irradiance and shadowing effect) on panels' performance were studied.
