Diagnosis and Countermeasure Research on Restrictive Factors of Household Photovoltaic Development in Shunyi District

Abstract

In order to mitigate climate change and global warming, and to balance the relationship between energy consumption and carbon emissions, China has put forward the “double carbon” goal, which will promote the construction of household photovoltaic as an important part of development. Distributed photovoltaic has the characteristics of high construction cost and long cost recovery cycle, which are unfavorable factors restricting large-scale promotion. and has been relying on national financial subsidies for a long time in the early stage of development. Under the incentive of high subsidies, the scale of China􀆳s distributed photovoltaic industry has expanded rapidly and maintained a high-speed development trend for many years. However, the large-scale development is accompanied by a surge in government subsidy funds. The high subsidy funds are difficult to be sustained, and the distributed photovoltaic industry is facing the overall trend of subsidy decline. This paper takes Shunyi District of Beijing, the first batch of pilot areas for rooftop distributed photovoltaic development in the whole county (city, district) in China, as an example. Through questionnaire survey, field interview and model analysis, this paper reveals the difficulties faced by household photovoltaic development in this area, identifies the main constraints and problems of photovoltaic development in this area, and quantitatively analyzes the influence degree of various factors. On this basis, based on the theoretical perspective of ‘cooperative governance’, this paper attempts to construct a G-P-M-S incentive system for household distributed photovoltaic development, which covers the government, public, market and society, and condenses the policy orientation of coordinating ‘cross-level’, ‘ cross-department’, ‘cross-subject’ and ‘policy tool integration’, and puts forward specific policy suggestions in light of the actual situation of Shunyi District, so as to provide support for Shunyi District to promote the development of photovoltaic industry and realize green and low-carbon transformation.
