Manufacturer and developer of the concentrating solar technology SunOyster Systems has signed a contract with the Yonghao Gangue Power Plant to deliver 63 concentrator photovoltaic (PV) systems in the Chinese province of Shanxi.
Initially, SunOyster will deliver 13 hybrid systems of the SunOyster zero series to supply energy to Chinese apartments. The deliveries are scheduled in the fall of 2014.
SunOyster said that it will install the high quality back-contact silicon cells that have an electrical system efficiency of 15%.
These hybrid systems use a heat transfer fluid to actively cool their PV cells. This can then be used for heating and hot water production as well as to drive refrigerating machines.
The thermal efficiency of this system is approximately 60% and it can be used at heat transfer fluid temperatures of up to 100°C.
According to the company, the second delivery of SunOyster consists of concentrator cells with a maximum efficiency of 30% and can be used at heat transfer fluid temperatures of up to 200°C.
Concentrator systems’ mirrors have a surface area of 16m² and are able to achieve 5kW of electric and 7.5kW of thermal power.
Electricity generated by the cells is fed into the grid, while the co-generated heat will be used by the operator Yonghao Gangue Power Plant to pre-heat feed water for the operation of a coal-fired power plant.
Yonghao Gangue Power Plant managing director Hongbo Kung said that the SunOyster systems will help in saving fuel and relieve the atmosphere from carbon dioxide and fine dust, the latter of which has become so critical in China.
