Photovoltaic building integration is the application of solar power a new concept, simply put the square of solar photovoltaic power generation is installed in the building envelope surface to provide electricity. According to the combination of photovoltaic square and building in different ways, photovoltaic building integration can be divided into two categories: one is the combination of photovoltaic square and the building. The other is the PV array and building integration. Such as photoelectric tile roof, photovoltaic curtain wall and photoelectric top.
In both cases, the combination of photovoltaic arrays and buildings is a common form, particularly in conjunction with building roofing. Because the combination of PV array and building does not take up additional floor space, it is the best installation method of PV power system in city. The integration of PV arrays and buildings is a high-level form of BIPV, which requires a higher level of PV modules. PV modules not only meet the functional requirements of photovoltaic power generation but also take into account the basic functional requirements of the building.
"Twelfth Five-Year" period, will create 2000 conservation-oriented public institution demonstration units. In addition to public institutions, commercial institutions as a result of large electricity consumption, the willingness to participate in energy conservation is relatively high, and has the financial advantages, should also give priority to the development of photovoltaic building integrated model.
