Cosin Solar Technology Co., Ltd. (formerly referred to as Zhejiang Supcon Solar Technology Co., Ltd.), Cosin Solar for short, founded in 2010, is the world's leading provider for integrated solutions of Molten Salt Tower CSP, focusing on the research of Tower CSP and High-temperature Molten Salt Energy Storage technology, equipment and engineering application, and aiming to use advanced and efficient CSP technology to provide high-quality and low-cost clean energy.

Through years of dedication in CSP technical research and engineering practice, Cosin Solar has successfully mastered integrated molten salt tower CSP technologies, and established the whole industry chain of CSP, which realized the industrialization and localization of core equipment. At the same time, Cosin Solar has developed a set of High-temperature Molten Salt Energy Storage solutions, and realized large-scale manufacturing of related equipment.

Based on the technology excellence, Cosin Solar has achieved a series of milestones as follows:

- In 2013：SUPCON SOLAR Delingha 10MW Molten Salt Tower CSP Plant was synchronized to the grid, which became the 1st commercialized CSP plant in China and 6th commercialized tower CSP plant in the world.
- In 2014：SUPCON SOLAR Delingha 10MW Molten Salt Tower CSP Plant became China's 1st CSP plant entitled to feed-in tariff at 1.2RMB/kWh.
- In 2016：The Molten Salt System of SUPCON SOLAR Delingha 10MW Tower CSP Plant was commissioned, which became China's 1st and world’s 3rd Molten Salt Tower CSP plant.
- In 2018：SUPCON SOLAR Delingha 50MW Molten Salt Tower CSP Plant was synchronized to the grid, which is one of China’s first batch of CSP Demonstration Projects.
- In 2019：POWERCHINA Gonghe 50MW Molten Salt Tower CSP Plant was synchronized to the grid, which is one of China's first batch of CSP Demonstration Projects. Cosin Solar is the technology provider, equipment supplier of the solar collecting system and commissioning service provider of the project.
In the same year, Cosin Solar signed the EPC contract of Greece Minos 50MW CSP project with the consortium composed of CGGC. Chinese President Xi Jinping and Greek Prime Minister Kyriakos Mitsotakis witnessed exchange of the Multilateral Cooperation Agreement of the project, and it is also the first-time overseas presence of China's CSP industry with complete life cycle of technology, equipment, engineering, capital and operation.

247Solar, Inc. was formed in 2015 by solar industry pioneer Bruce Anderson to commercialize the 247Solar Plant™, using technology originated at the Massachusetts Institute of Technology (MIT). Bruce began his solar career with his master’s thesis at MIT on the subject of solar energy. In 1985, Bruce became the first recipient of the American Solar Energy Society’s Lifetime Solar Contribution Award. He later served on the National Advisory Board of the Solar Energy Research Institute, now the National Renewable Energy Institute (NREL).

In 2009, Anderson realized that a breakthrough high-efficiency heat exchanger, invented by MIT mechanical engineering professor Dr. David Gordon Wilson, and being developed by the company they formed together, Wilson TurboPower, would enable an entirely new approach to concentrated solar power (CSP) with higher performance and lower cost. In 2010 the U.S. Department of Energy awarded the company $6 million to further advance the technology, and the engineering of key components began. In 2015, Anderson formed 247Solar and acquired Wilson TurboPower’s solar technology.
In 2018, 247Solar received private investment capital to enable the engineering and construction of its first full-scale 247Solar Plant. The Commercial Demonstrator, under construction at the Company’s Arizona facility, will commence operation in early 2022.

Founded in 2009, Royal Tech CSP Limited has been specialized in the R&D and industrialization of solar thermal key technologies based on broad cooperation with world famous scientific institutes like Fraunhofer ISE, DLR and CIEMAT-PSA. We have been actively participating in the compilation of multiple International (IEC), national and industrial standards. We have made various breakthroughs in terms of technology and industrialization of vacuum receivers, and managed to supply large scale CSP power plants overseas. We started early to successfully demonstrate our parabolic trough solar field capabilities, continuously verifying new components and technologies for solar thermal applications.As a developer and technology provider, 150MW capacity of parabolic trough projects that we participated were selected into the first National CSP Demonstration Program. Two projects are in process to be implemented. Royal Tech CSP Limited, the winner of SolarPACES 2017 Technology Innovation Award with Wacker Chemie AG, becomes the first Asian company to get this award in history.
