A solar water heating system incorporating parabolic trough collector (PTC) with Phase change material (PCM) is simulated using TRNSYS® software. The simulation is carried out to predict the hot water availability during the peak hot water demands of the morning and evening hours. Lauric acid (LA) is used as the primary heat transfer fluid (HTF) to extract the sun’s energy in PTC whereas, water is used as the secondary heat transfer fluid to extract heat from the primary heat transfer fluid. The study models a medium temperature, concentrating parabolic trough collector without any solar tracking components. TRNSYS® simulation components have been studied completely using Type 1245 parabolic trough collector with Type 533 horizontal storage tank with heat exchangers, which fulfils daily hot water demands of domestic and industrial applications. The storage tank is vertically stratified to regulate the temperature of HTF coming out of the collector. The results showed that LA having a thermal conductivity of 0.975 KJ/hr-mK provides a peak energy gain of 18500 KJ/hr in February and 5000 KJ/hr in July along with a 100°C rise in temperature for the city of Mangalore, India. The weather condition of the city provides an average annual collector efficiency of 26%.
