A solar collector is a device that transfers the solar radiation energy it receives to a heat transfer working fluid. Therefore, solar collectors are key devices in solar energy utilization, making the research, application, and testing of solar collectors crucial for the efficient use of solar energy resources.

In recent years, with the rapid development of solar thermal utilization system engineering, solar collectors have been widely applied in various thermal utilization projects. Their quality directly affects the performance and quality of the constructed thermal utilization systems. In accordance with the technical requirements of national and international standards, and based on over a decade of R&D and production experience in solar laboratories, the company has developed a high-precision, dual-axis, fully automatic solar tracking collector testing system that meets both China's solar testing standards and international dual standards (EN&ISO) for quasi-steady-state and unsteady-state conditions. It features high testing accuracy, stable performance, and a high level of intelligence. It has been used and highly recognized by multiple international dual-standard (EN&ISO) solar testing laboratories and other users, making it the most advanced solar collector testing system in China to date. This ensures the performance, construction quality acceptance, and re-inspection of solar thermal utilization system engineering, making it an essential testing device for quality inspection centers, building science research institutes, construction engineering testing units, manufacturers, and research institutions in universities.

TMC-2B Solar Collector Testing System Product Features
