Analysis of Electrical Characteristics and Performance of Poly-Crystalline Solar PV Module by I-V Tester Under Temperature and Solar Irradiance Variation in Spring Season

The performance of the Solar photovoltaic (PV) panel depends mainly on two environmental factors, namely temperature and solar irradiance. These factors affect the PV output parameters such as maximum power, short-circuit current and open circuit voltage. This work investigated the behavior of a polycrystalline solar PV panel's electrical characteristics under variation in temperature and solar irradiance in spring season. This was done through experiment and the results validated with simulation in Matlab software. The experimental results were compared to simulation results and showed that the module electrical outputs change with the variation in temperature and solar irradiance. These two factors affect the PV module performance during the spring seasons and its output is more efficient due to favorable surface temperature and solar irradiance variations striking the module during peak hours of the day.
