In the field of new energy, solar photovoltaic (PV) technology is increasingly integrated into our daily life, especially in the combination of building and PV, many innovative applications have emerged. Among them, BMPV, BIPV, and BAPV are three common PV building application models.
BMPV(Building Mounted Photovoltaic): Building Mounted Photovoltaic
BMPV, or building-mounted photovoltaic power generation systems, is a building photovoltaic application in a broad sense. It covers all PV systems installed on buildings, whether integrated into the building structure or simply attached.
Features: BMPV is characterized by its broad applicability and flexibility. Whether in residential, public or industrial buildings, PV systems can be installed wherever conditions permit.
Advantage: BMPV's advantage lies in its ability to transform unused building space into a clean energy production site, which not only reduces electricity bills, but also contributes to environmental protection.
BIPV(Building Integrated Photovoltaic) : Photovoltaic Building Integration
BIPV, or Building Integrated Photovoltaic, refers to the simultaneous design, construction, and installation of solar photovoltaic power generation systems and buildings, realizing a perfect combination with buildings.
Features: As part of the external structure of a building, BIPV not only has the function of power generation, but also functions as a building component and building material. It is able to integrate perfectly with the appearance and function of the building and even enhance the aesthetics of the building.
Advantage: The advantage of BIPV is its high degree of integration and aesthetics. Due to the close integration of the PV modules with the building, it makes the whole system more stable and more resistant to wind and earthquake. At the same time, BIPV can also effectively reduce building energy consumption, improve the energy efficiency of buildings, and realize energy saving and emission reduction.
BAPV(Building Attached Photovoltaic): Building Attached Photovoltaic
BAPV, a solar photovoltaic power generation system attached to a building, is also called a "mounted" solar photovoltaic building.
Features: The main function of BAPV is to generate electricity, and it does not conflict with the function of the building. It can provide a clean power supply to the building without destroying or weakening the original building function.
Advantage: The advantage of BAPV lies in its flexibility and cost-effectiveness of installation. Since it does not require major changes to the building, the installation cost is relatively low. At the same time, BAPVs can be optimized and designed according to the actual conditions of the building and light conditions to improve power generation efficiency.
Difference and Connection between BMPV, BIPV and BAPV
BMPV is a broad concept, which includes two forms BIPV and BAPV. BIPV focuses more on the perfect integration with the building, emphasizing the dual function of PV modules and building materials; while BAPV focuses more on the flexible installation and cost-effectiveness in existing buildings. The three together constitute the main mode of PV building application, providing strong support for the development of green buildings.
With the increasing awareness of environmental protection and the rapid development of new energy technologies, the integration of photovoltaics and buildings will become an important trend in the future development of architecture, and BMPV, BIPV, and BAPV, as the three main modes of photovoltaic building applications, each with its own features and complementary advantages, will make an important contribution to the promotion of green buildings and sustainable development.
