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.
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.
Scaling up the implementation of Building-Integrated Photovoltaics (BIPV) in Shenzhen could effectively reduce the dependence on traditional energy sources and minimize the environmental impact of buildings . Shenzhen is a city with a high population density and limited land area, characterized by a dense concentration of high-rise buildings.
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.
Based on the developed mathematical model, this paper assesses the solar irradiation resources and BIPV potential of residential buildings in different climate zones of China. It is found that roofs are the first choice for BIPV installation, followed by south façades, especially in high-latitude cities, and then east and west facades.
Despite the city's subtropical climate and abundant solar energy resources, along with numerous buildings with potential for PV power generation, architects remain cautious about adopting extensive PV panels on the facades of high-rise buildings.
