The dish-type photothermal power generation system has a long life. According to the relevant information, the service life of ordinary boilers is 15 years, the service life of air source heat pumps is 7-10 years, and the service life of traditional solar thermal collectors is 10 years. Qingyun’s main dish-type thermal collectors adopt photothermal power generation technology. The service life is up to 25 years. The dish system is also a point focusing system and is the earliest solar thermal power generation system in the world. The dish system, also known as the parabolic mirror Stirling system, is composed of many parabolic reflectors, which are received at the focus of the parabola. After the heat transfer medium in the receiver is heated, it drives the Stirling engine to generate electricity. The concentrating ratio of the dish system is very high, ranging from hundreds to thousands, and the focusing temperature can even reach 100 degrees and upwards. It is highly efficient and more flexible in terms of ground slope requirements. However, it still lacks advantages in terms of cost, and the technology also needs to be improved. Disk systems are more suitable for independent power stations in remote areas. It can be used as a single unit or multiple units in parallel, and is suitable for small-scale power generation.
