Modeling of Solar Photovoltaic Assisted Rechargeable Battery for Running a Hospital In Remote Area

In the study, solar photovoltaic (PV) assisted rechargeable battery is used for running a hospital in remote area in Kolkata region. Solar PV is used for running the different appliances of hospital in which during peak sunshine hour’s power is supplied to appliances and excess energy is used for charging rechargeable battery to be made available during period of non sunshine hours. The hospital contains 125 lights of 100 W each, 1 water pump of 500W , 75 fans of 65W each and a heater of 500kW for supplying hot water which is operated for 24 hours a day.2 modules in series and 15686 modules in parallel of Central Electronics Limited Make PM 150 can meet the electrical energy needs of designed hospital. The power back up is provided using a battery bank with a rated capacity of 156859 Ah. The heater of 500kW will supply 5714.28kg/hr or 5.714m3/hr of water throughout the day.
