Those PV modules can not only replace part of such traditional structures as roof slab, tile, window, building elevation and rain-proof shelter, but also can be made to own various functions, such as PV/thermal system, combination with illumination and sun shade, etc.
At present, BIPV is widely applied on exposed walls, sun-shading shelters, patios, tiles, roofs, sound-proof walls, as well as in fields of private apartments, schools, hospital buildings, airports, platforms of subway stations and large workshops.
With the changing fields of PV power generation, China has made great progress in research and development of BIPV system. In 2002, 10KW integrated grid system was built in Fengxian, Shanghai, which realized automation. In 2003, an ecological demonstration project was established in Shanghai and the 5KW integrated grid system combined well with construction with international top technologies.
Shanghai Solar Energy S&T Co., Ltd (SSEC) also established integrated demonstrative office building with six first-initiated technologies of directly combining solar electrical power generation and construction. Today, the total installed capacity can reach 40KW and energy self-supply can basically realized with integrating geothermal air condition technologies.
