Power-Energy Optimization of Solar Photovoltaic Device Modeling

Most recent technological advancement of solar photovoltaic (PV) devices have dramatically increased the significant part of renewable energy worldwide through the generation of electric energy. The present paper proposes a novel model for achieving optimum power-energy (PE) from simulation and graphical representation of solar photovoltaic device (SPV) models. First power and current versus voltage performance is characterized. Later PV device output current versus output voltage characteristic is explained for initial as well as optimal parameter criterions. Finally, optimum power-energy is obtained from graphical representation of output power versus output voltage characteristic for proposed model with varying irradiance and temperature conditions. From the simulated and graphical performance analysis, it clearly exhibits the significant enhancement of power-energy and optimal PE is achieved from the novel SPV device model.
