ECONOMIC ANALYSIS OF A GRID CONNECTED SOLAR HYDROGEN PV SYSTEM

The grid connected solar hydrogen energy system has been developed in order to investigate the performance under the local climate conditions. The grid connected solar hydrogen energy system (GCSHES) have the capability of overcoming the problems that occur on the grid connected power system (GCPS) when there is a black-out of grid electricity. Moreover, stand alone power system (SAPS) requires batteries, and larger hydrogen tank capacity is required for higher energy generation. An experimental GCSHES has been setup and tested. The GCSHES consists of subsystems photovoltaic (PV) array with 40 PV module with its capacity of 5000 Wp, inverter capacity (6000W), electrolyzer, hydrogen tank and fuel cell (500 W). The monthly efficiency and performance of PV array is 12.7% and 26%, while the efficiency and performance of inverter is 95.1% and 98%, respectively. The techno-economical analysis indicated that the pay back period of this system is 18 years.
