Abstract: This paper deals with the feasibility of using a coupled solar parabolic trough collector-latent heat thermal energy storage system for large buildings hot water production. A detailed dynamic thermal model is developed to investigate the thermal performance of the studied system under realistic meteorological conditions. The validation of the developed model is carried out through comparing numerical results with existing numerical and experimental data and a good agreement is obtained. Three kinds of phase change materials are studied and the optimal design of the storage system is determined for weather conditions of a typical summer day in the south of France. Both charging and discharging processes of the latent heat storage system are investigated and obtained results show that using the storage system is suitable to provide hot water all the night. These results indicate also that for a mass flow rate of 1800 l/h, using RT-55 as phase change material in the studied system is preferable compared to RT-42 and RT-65. Finally, it is concluded that using the proposed system with RT-55 as storage medium is suitable for large buildings hot water production and the system is able to produce hot water within the ranges of 85–36 °C and 63-38 °C, during daytime and nighttime operation, respectively.
