A study on development of PV cell/module and output power variation based on two-diode model

As conventional energy sources are declining day by day and also they are one of the main reasons for polluting the environment, the focus is turning into the environment-friendly and Grid connection compatible renewable energy source which is PV system. There is an impact of environment factors on the electrical behavior of PV modules which accurately interpreted as output characteristics and the rate of conversion efficiency for a PV module is very low. Hence an accurate modeling of PV module is required. This paper proposes a study of PV system performance with better analysis and higher accuracy level even at low irradiance utilizing two diode cell based PSPICE model. And an effort is made utilizing two diode model based PV cell to analyze the output power variation due to partial shading effect. VI and PV characteristics are plotted by using the environment parameters such as Temperature and insolation levels as variables. Optimal charging of Battery as well as high gain inverter efficiency configuration is also discussed. The PSPICE simulation is performed in order to study the interfacing with MPPT algorithms and converters PV module. PSPICE simulator is a Platform to deal with non-linear devices such as diodes and Transistors availed with a number of parameters to achieve numerical convergence.
