Performance analysis of mono and poly-crystalline silicon photovoltaic modules under Agadir climatic conditions in Morocco

The evaluation of a solar photovoltaic (PV) technology helps to identify its suitability for a specific location. The main objective of the present study is to assess the suitability of mono-crystalline silicon (mc-Si) and poly-crystalline silicon (pc-Si) PV modules with almost similar characteristics under Agadir climatic conditions. Electricity yield of these modules is calculated from the uninterruptible measured current–voltage curves from sunrise to sunset during a year. The influence of weather conditions, global irradiance and temperature, on the performances of the modules is assessed and as a part of considerations in the PV power plant design that the output power from pc-Si PV modules is found greater. Calculated annual average final yield (Yf), and performance ratio (PR) for mc-Si and pc-Si PV systems are (1602.22 kWh/kWp, 0.71), (1691.85 kWh/kWp, 0.75) respectively.
