Stand-alone photovoltaic systems supplying remote houses have storage battery banks. The battery banks improve the reliability of these residential systems. There is a maximum-voltage limit of the battery bank to protect it against overcharging. Maintaining the battery-bank voltage at its maximum limit is accompanied with reduction of captured energy from the renewable energy source. In this paper, standalone residential PV system is studied. Control technique for a motor driving water pump is developed such that the problem of reduction of captured power is reduced. Experimental setup is constructed in the laboratory to verify the performance of the system.
