摘要：The main objective of this study is to compare the one-year performance of 5.94 KWp grid- connected PV array systems, consisting of three types of mono-Si (2.04KWp), poly-Si (2,04KWp) and a-Si (1,86KWp) photovoltaic solar panels, installed on the roof of the Faculty of Sciences Dhar El Mahraz in Fez. The study is based on data collected in 2017 on energy production. The performance elements evaluated monthly and annually include: energy output, system efficiency, reference yield, final yield, performance ratio, annual capacity factor. The results show that poly-Si technology has the best performance. A comparison between PV Production in different locations in the world and will presented, also we can conclude that Northern Morocco is a good region for PV production.
