Abstract :
The work portrayed in this paper furnishes knowledge about advanced solar photovoltaic (PV) conversion system. This PV system is fast and tracks more output power than conventional PV systems. In literature, the PV parameters of a double exponential model were designed with the help of Levenberg-Marquardt algorithm. In this paper, the PV parametric values were taken into consideration and implemented in a single exponential model with curve fitting method. The results of a conventional PV system and it was observed are compared with the implemented PV system and observed that, the implemented PV system tracks 23 % excess power than the conventional one. Finally, the PV system is implemented with a series of 2000 interconnected PV cells for higher voltage applications, due to its unfussiness and lower cost. The MATLAB simulated models are presented and discussed.
