Description
Summary:A scheme has been implemented to improve the system efficiency, battery life and payback period for a hybrid solar photovoltaic system. A standard solar photovoltaic system has been modified to meet the complete energy demands without an increase in system’s photovoltaic capacity and any new investments. A 220 V alternating current system is replaced by a 48 V direct current system. The actual results show that by using direct current appliances instead of alternating current appliances, 50.6% power savings are achieved through reducing load. A 48 V direct current micro grid is implemented and already installed appliances are modified to operate on 48 V direct current from distribution line. Universal and induction motors in rotary appliances are replaced by brushless direct current motors having minimum electro-mechanical and commutation losses. This implemented direct current system reduces the power conversion stages, diminishing the associated power losses and standby losses resulting in the overall increase in the efficiency of system by 9.1%.
