Abstract: The aim of this study is focused on "energetics" or energy analysis and evaluation of greenhouse gas (GHG) mitigation potential of solar water heating system (SWHS) having 100 litre per day (lpd) capacity in 28 states of India. Different types of collectors are used in solar water heating system, which may affect on the feasibility of the system. So to analyze this factor, the present approach focused on three types of glazed flat plate collectors. In addition to this, the feasibility of the system also does depend upon the end user applications. So to incorporate more feasible analysis, three different scenarios were considered. For the analysis of environmental impact of the system, GHG emission mitigation potential has also been evaluated by assuming the replacement of the system with frequently used fuels, viz., natural gas, coal, diesel, etc. This was done for both seasonal and annual use of this renewable energy thermal device. The result of this study shows that energy payback period (EPBP) and energy yield ratio (EYR) values for selected locations are in the adoption level. In case of coal, the GHG-emission reduction was found to have a maximum value of 22.4 tCO2 for the state of Rajasthan and a minimum value of 13.4 tCO2, for Jammu & Kashmir, for 20 years of useful lifetime of the system.
