Comparative study of three photovoltaic technologies (Monocrystalline – Polycrystalline – Amorphous)

This work aims to do a comparative study of threephotovoltaic technologies, in terms of electric power producedand the calculation of the photovoltaic (PV) efficiency, theresults show that the photovoltaic technologies monocrystallineand polycrystalline have a good photovoltaic efficiency thanamorphous technologie, in the weather conditions of Safi, so wecan say that these photovoltaic technologies, are the applicablein Safi
