摘      要：Two high concentrating solar systems have been established with dish concentrator and plane-mirrors array *** the paper,the thermal performance has been experimentally studied with jet water cooling device and flat microchannel water-cooled *** experimental results show that the maximum surface temperature difference of the dish concentrating system is greater than 20°C,while the plane-mirrors array system is lower than 4°*** indicates that the plane-mirrors array concentrator has better *** the concentration ratio increases,the electrical efficiency of the concentrating photovoltaic system gradually *** the concentration ratio is 200,the electrical efficiency of the photovoltaic system is 25%.The concentration ratio of 500 times or less is considered to be a suitable value,and then the electrical efficiency can still exceed 20%.It is found that the plane-mirrors array solar system is more suitable for the photovoltaic system than dish type system,which is only suitable for thermal power generation system.
