Life cycle energy analysis is important for the estimation of greenhouse gas emission and global warming parameters. This paper presents the assessment of energy payback time (EPBT) and energy return on energy investment (EROI) of a 3.4 kWp solar photovoltaic (PV) system installed in the rooftop of ITER, Siksha “O” Anusandhan, Bhubaneswar, India. The photovoltaic system is analyzed to find its viability aspect to its cost economics and energy and to compare its performance with some previous work available in the literature. The energy analysis was carried out by embodied energy basis and the results of the installed stand-alone PV system were compared with an equivalent grid-connected PV system. The EPBT was found to be 4.61 and 3.78 years while the EROI was found to be 5.42 and 6.62 for stand-alone system and grid-connected system, respectively.
