Analysis of weather impact on the yield of PV plants installed in two antagonists cities in Morocco

The aim of this work is to compare yield photovoltaic and installations performance of different technologies exposed under natural outdoor conditions in two different sites in Morocco (Beni Mellal and EL Jadida). The plants studied consist of three technologies monocrystalline silicon (mc-si), amorphous silicon (ac-Si) and polycrystalline silicon (pc-si). The experimental data has been recorded over one-year period. The comparative analysis included annual energy production and performance ratio. From these studies, it can be observed that PV installations with pc-Si have the highest energy yields. Regarding the performance ratios, in Beni Mellal the higher values observed only for the pc-Si technology, although in EL Jadida, the mc-Si and pc-Si technologies present almost the same performance ratio.
