|Keywords:||Grid-Connected Systems, Net-Metering, Photovoltaic Power Systems|
A 1k-W roof-top grid-connected PV system has been developed for unstable grid supply of developing countries like Bangladesh. The grid-connected inverters available worldwide do not work properly in unstable grid supply. To overcome this problem a compensating circuit has been developed using a variac. The performance of the system has been studied for a long time in different weather conditions. A preliminary economic analysis of the system has also been done. It is found that the system works satisfactorily in unstable grid system with the help of the compensating circuit. The practically obtained efficiency of the system is around 80% and the cost of electricity produced by the system is about 11Tk/kWh.
