Leading Technology

A Reliable Provider for Molten Salt Tower CSP Solutions

Leading Technology

CSP is a highly complicated technology that involves various specialties. With years of endeavor in R&D, we have mastered core technologies of molten salt tower CSP in solar concentration, receiver, thermal storage & exchanging, environment adaptable design, construction and O&M customized for extreme weathers, proven on utility-scale projects.

R&D Excellence

Cosin Solar, specialized in innovation and R&D, has developed an R&D team with more than 100 members. The provincial high-tech R&D center we have is China’s largest, multifunctional, and well-equipped incubator for CSP technology and facilities. The center supports all necessary facilities, equipment, and experimental conditions for innovation, and can perform system functional verification, application tests for heliostat, heliostat calibration system and heliostat control system, and special tests for receiver, molten salt system and other auxiliary systems, covering the whole process from solar concentration through storage.

Cosin Solar continues to advance CSP technology and to promote industrialization of CSP by developing its own cutting-edge intelligent heliostat, large-scale solar field control and molten salt thermal storage & exchange technologies. Cosin Solar led and participated in the preparation of 7 international standards and 9 national standards. We have undertaken one World Bank China Renewable Energy Scale-Up Program, two national 863 Programs, two national key research and development projects and several provincial and municipal-level scientific research projects. We repeatedly won the top places of provincial and municipal science and technology progress prizes. In addition, we won the Solar PACES 2020 Technology Innovation Award issued by the world's most authoritative CSP academic society, being the first and only independent CSP enterprise in Asia that wins this award.
