Abstract: Solar thermal utilization is one of the important application forms of renewable energy. This paper reviews the important breakthroughs in key components and integrated technologies,such as solar collectors,heat storage,and system design methods in China in recent years. It summarizes the latest developments in application forms such as solar hot water supply,solar heating,solar cooling,and solar energy industrial and agricultural applications,and looks forward to the development trend of solar thermal system. The application form of solar thermal utilization in China is mainly focused on solar hot water supply,which has developed towards intelligence and refinement. Driven by the clean heating process and the goal of emission peak and carbon neutrality,the application of solar thermal utilization technology in heating,cooling,industry and agriculture in China is gradually increasing,and the application forms are diversifying. A multi-energy coupled system mainly based on solar energy can effectively solve the problem of solar energy resource instability while improving system economy,which is an important direction for future low-carbon development.
