Abstract

In this project Modelling of solar photovoltaic MPPT system by using P&O algorithm is implemented. Solar cells convert sun light into electricity, but have the major drawbacks of high initial cost, low photo-conversion efficiency and intermittency. The current-voltage characteristics of the solar cells depend on solar insulation level and temperature, which lead to the variation of the Maximum Power Point (MPP).Here to improve photovoltaic (PV) system efficiency, and increase the lifetime of the battery, a microcontroller-based battery charge controller with maximum power point tracker (MPPT) is designed. Hence it gives effective outcome.
