Abstract :
A low cost maximum power point tracking (MPPT) technique is proposed in this paper for high power efficiency in photovoltaic systems to track the maximum power point (MPP). Compared to the various studies of the MPPT topologies, the proposed implementation is achieved by monitoring the power slope conditions of solar panels. The post grid-connected DC-AC inverter helps feedback the transformative power for providing AC power. Experiment results demonstrate the rapid tracking operation of MPP and a high tracking effectiveness of 97.3%.
