Technical and Financial Feasibility Study of Solar Water Heating System Installation in Students' Mess in Bhutan

Gom Dorji

Abstract: This paper gives the technical and financial feasibility study of installing solar water heating system (SWHS) in students' mess of three colleges of the Royal University of Bhutan. The two colleges are located in the West and one in the East. For technical feasibility studies, data like solar irradiance, temperature, and daily hot water demand are collected. The technical data are fed as input to System Advisor Model (SAM) software and simulated and found technically feasible to install the SWHS in selected sites. The annual energy saving from SHWS is 5293 kWhr, 9257 kWhr, and 6304 kWhr for College of Natural Resources (CNR), Paro College of Education (PCE), and Jigme Namgyel Engineering College (JNEC) respectively. The final energy saving from SWHS is taken for financial analysis. Considering the project period of 15 years, the financial feasibility study is also conducted. This report also includes the unit cost of energy.
