There are relatively few researches on BIPV design of rural residential building in China. According to different ways of combining photovoltaic system and building envelope structure, some scholars (Du 2013; Liu 2018; Liu and Sun 2014) proposed that BIPV can be divided into two categories: “installation type” and “building material type”.
Based on the above reasons, the Chinese government plans to vigorously promote the construction of photovoltaic system in rural areas, which has been included in the 14 th Five-Year Plan of renewable energy development. In the foreseeable future, rural photovoltaic system in China will achieve rapid and sustainable growth. Figure 4.
Thirdly, a variety of photovoltaic building integration modules are used, with a total solar power generation power of about 400 KWp, making it a benchmark project for photovoltaic building integration in China , as shown in Table 10.
Two principal classifications can be defined for building photovoltaic array mounting systems: BIPV and BAPV . BIPV are considered a functional part of the building structure, or they are architecturally integrated into the building's design.
However, the lifetime of buildings in China is required to be at least 50 or more years, depending on the importance of the building. Thus, photovoltaic components do not need to last as long as buildings, but easy maintenance and replacement of photovoltaic components are important.
As shown in , since 2013, China’s newly added distributed photovoltaic installed capacity have fluctuated upward, and reached 29.28 GW by 2021, accounting for 53.4% of the total, and exceeding the centralized photovoltaic system for the first time in history.
