This paper describes the selection and encapsulation of phase change materials for solar domestic hot water (SDHW) systems, and reviews the progress of research on phase change materials for energy storage in SDHW system tanks, solar collectors and SDHW system cycles and their improvement and enhancement of heat transfer, and makes suggestions and outlooks for the development direction of phase change material applications for SDHW systems. The research shows that paraffin wax and sodium acetate trihydrate are widely used in water tanks and collectors of SDHW systems. The encapsulation form is mainly the macro encapsulation of plastic, aluminum, stainless steel, in the shape of tube, column, ball, etc. Phase change materials added to traditional SDHW systems can improve the thermal storage performance of solar domestic water heaters. There is still much room for upgrading and improving the thermal storage performance.
