The world faces an increasing an environmental pollution basically as a result of combustion of conventional energy sources. India currently depends on conventional energy to supply power to her teaming population. Due to this, the energy generated does not meet demand. Consequently, the power supply is erratic and areas isolated from the main cities lack power supply. Therefore, the need to develop a non-conventional source of energy generation such as solar cannot be overemphasized. A photovoltaic system that can increase energy output and/or supply power to isolated areas of the country is a good choice, considering the abundance of solar radiated energy in India. In this work as PV system model is designed to work either as a standalone PV system or as grid integrated and the payback period is calculated for the same. The developed model may be useful in the prediction of PV cells behavior under different physical and environmental parameters. The result obtained showed the maximum power output and the corresponding maximum voltage of solar module. Study results demonstrate that, under complex irradiance conditions, the power generated by the new configuration is enhanced than that of the traditional configuration. The solar PV system can be widely used in many consumer applications, such as PV vests for cell phones and music players.
