Analysis of Environmental Parameters Sensitivity to Improve Modeling of a c-Si Panel

Abstract

This work is about sensitivity analysis of environmental parameters, namely, irradiance, ambient temperature and wind speed which are important to design the PV system. Environmental parameters are correlated with each other, and together they influence the PV system output. Hence, different values of environmental parameters are used in the five parameters single diode model to simulate. Using this model one environmental parameter is observed at a time. Using the observed environmental values and estimated values the error function is built. The error function is significant to understand the reactivity of the crystalline PV panel when the environmental parameters are changed. It does not give the efficiency of energy conversion from PV system. Instead, it gives the in-depth knowledge of the specific parameter like a minimal change of that parameter how much affect the output. Once modeling of the PV system is precisely done then, it is stress-free to estimate approximate output under different environmental condition. This is important when PV system is connected to the smart grid.
