The current study has been carried out to compute Life Cycle Assessment of the solar based multi-generation system. This assessment represents the overall rate of emission in the environment during the entire lifetime operational activity of the specific component which is based upon the component's material, process and treatment, upstream process, and finally the disposal rate management. The Life Cycle Assessment has been performed by considering the operational life of components by 30 years, depicting the operating period of 7500 h per year. The results obtained by performing LCA signifies the important aspects regarding parameters, variables and working capability of the system in terms of rate of emissions by the input values induced and the accurate output results produced by the system. The Eco-Indicator 99 method has been employed to perform the calculations and the impact on environmental per unit time (pts/s or mpts/s) is assigned to evaluate the rate of emissions effecting the atmosphere. © 2021 Elsevier Ltd
