Toward a prediction of the photovoltaic based power production from Experimental Thermal modeling

Power production based solar cells are sensitive to temperature. In real conditions, the effective Photovoltaic (PV) module operating temperature is affected by randomly varying of solar radiation, ambient temperature and wind speed. Thus, the energy balance of photovoltaic (PV) cells and the associated power production is mainly modeled based on climate variables. This paper investigates the experimental influence and relationship of the temperature and solar radiation changing effects on the system performance in terms of power production of PV cells. An experimental approach leading to an expression models the energy transfer processes and electrical energy production for one specific site is studied. The proposed gait is reproducible and suitable on different site. Our study is based on experimental results set up of 6 PV (1 kW) multicrystallin silicon panels under existing conditions and not indoor conditions.
