BMPV(Building Mounted Photovoltaic): Building
M
ounted 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
B
uilding 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
(Bu
ilding Attached Photovoltaic): Building Attached PhotovoltaicBAPV, 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.
With the development of photovoltaic technology, as two main PV application forms, BAPV and BIPV have gradually gained a lot of popularity in the market. BIPV refers to Building Integrated Photovoltaic, which mainly focus on the integration of new building and material with the PV industry. As a subdivision track for the future development of photovoltaic industry, BIPV is designed for the construction and installation of photovoltaic power generation system with new buildings at the same time and combine with buildings, so as to organically combine photovoltaic panels with building roofs and walls, and has a wide range of application scenarios.
BAPV means Building Attached Photovoltaic that is the power station is installed on the roof and outside the wall of the building that has been put into use, which has no impact on the original structure of the building. At present, as the replacement of BIPV, BAPV is more popular among the market. The reason is that the initial installation cost of BAPV is low and there is no need to replace the roof. Therefore, in the short term, BAPV does have enough advantages. But according to the latest forecast, this situation is expected to be changed in , that is, BAPV and BIPV will achieve return parity, and it is expected that the installed capacity of BIPV will grow faster, with a compound annual growth rate of 117% in to and 31% in to .
It is benefited from the deceasing initial installation cost and unique technical advantages and policy incentives. It is expected that the reduction of the cost difference between BIPV and BAPV will mainly come from economies of scale and technological progress. As a sustainable building material, it is generally believed that BIPV will enjoy additional subsidies, while BAPV may face the situation of subsidy decline or even no subsidy, which will lead to a lower market. In addition to IRR return parity, unquantifiable benefits such as security and elimination of hot spot risks will further increase the value of BIPV investment. As a result, the industry expects annual installations of BIPVs to outpace the growth rate of BAPVs, with a CAGR of 71% in to compared to 13% for BAPVs. That is to say, they are expected to achieve dynamic balance and synchronous development.
