摘要
In the current environment of the energy shortage and the environmental pollution, a series of the clean energy sources such as the solar energy show unique advantages. China's technical research on the solar water heating systems is quite mature. However, there is currently no accurate assessment of the environmental benefits of the solar water heating systems at home and abroad. This paper selects seven indicators from three aspects of the emission reduction benefit, the resident health benefit and the environmental improvement benefit to construct an environmental benefit evaluation system and evaluation model for the solar water heating system. Taking the Yinchuan area as an example, this paper conducts a study of the environmental benefit evaluation of the solar water heating system in the local area, and obtains the specific value of the environmental benefits of installing the solar water heating system in local buildings. Finally, it puts forward some suggestions for the local government to promote the solar water heating system.
