Solar heating is one of the effective ways of clean heating in northern China, which can achieve low emission and low energy consumption. However, the energy source of solar heating from the solar radiation, which is restricted by weather, region and season, has strong intermittency and instability.
ina's solar thermal heating market has gradually occupied the main capacity in operation inbusiness se ment of the market, of which the overall share of the project market China from 2000 to 2021.reached 74% in 021 and the r tail market 26%. Sales of domestic hot water syst ms are contin
In China, large-scale solar thermal systems for space heating and industry process heat just started in recent years. Projects mainly rely on subsidies from the government at the current stage. For example, the Langkazi Tibet Solar Heating project (see Section 6.2) is 100% subsidized by the central government.
By comparison, it is found that solar irradiation resources of more than 2/3 northern regions in China are superior to Denmark, Canada and Germany. Thus, solar energy clean heating based on the seasonal underground storage has great potential in China. 4.
In the market survey on China, only data for space heating and industrial applications were considered. According to these data, there are 55 systems with a total capacity of 212 MW in operation by the end of 2018.
