The impact of different photovoltaic panel currents

In this work, we performed a comparative analysis of the electrical energy production from photovoltaic power plants using different photovoltaic panel technologies; these technologies affect not only the degree of conversion of solar irradiation to electrical energy but also the ecological parameters concerning the use of photovoltaic panels by reducing CO 2 emissions. The photovoltaic (PV) array performance is significantly affected by solar irradiation, temperature and its configuration. Indeed, the array configuration has an impact to modify the series (Rs) and the shunt (Rsh) resistances that appear in its mathematical model. Moreover these resistances are dependent on temperature variation. Hence, the latter can affect I-V and P-V …
