The Two Giants of Photovoltaics: BIPV vs. BAPV

In today's pursuit of green and sustainable development, the construction industry is undergoing unprecedented transformation. From energy-efficient materials to intelligent systems, every innovation attempts to reduce our environmental impact. Among numerous emerging technologies, photovoltaic buildings are undoubtedly one of the brightest stars. But did you know that, depending on the installation method and whether the component appearance is customized, there are mainly two ways to combine photovoltaic power generation systems with buildings—BIPV (Building Integrated Photovoltaics) and BAPV (Building Attached Photovoltaics)?

 

BAPV has the attributes of "photovoltaic product" and "installation type," considered when existing buildings intend to install photovoltaics; BIPV has the attribute of "building," mostly used in new buildings. So what are the specific differences between the two?

BIPV

Building Integrated Photovoltaics: The Beauty of Seamless Integration

 

Imagine using photovoltaic components directly as building materials—pretty cool, right? That's the charm of BIPV. It seamlessly integrates photovoltaic components into building design, used as roofs, skylights, curtain walls, etc., replacing building decorative materials as needed, becoming an integral part of the building. It's not only aesthetically pleasing but also provides insulation and heat preservation. BIPV exists in an almost invisible way, adding a touch of technology to the building, like putting a high-tech "sunscreen" on your house, significantly enhancing the overall aesthetics.

 

From an industry perspective, BIPV has significant advantages in terms of installed capacity, waterproof reliability, and construction speed. Coupled with the continuous improvement of the upstream and downstream industrial chains, its future development prospects are increasingly broad.

BAPV

Building Attached Photovoltaics: Flexible and Convenient

 

BAPV is more like adding an "energy station" to an existing building. The distributed photovoltaic power generation system is additionally installed on the building's surface, such as on existing cast-in-place concrete roofs and color-coated steel roofs. The components do not affect the basic functions of the original building; they only generate electricity and are not directly part of the building materials. Its advantage lies in its flexibility and ease of installation, suitable for companies that need green energy transformation but do not want to make major changes to the building structure.

 

However, traditional BAPV systems, due to the additional installation of photovoltaic components on existing building roofs, have some disadvantages, such as structural safety risks caused by increased roof loads, installation stability problems caused by wind uplift effects, and damage to roof waterproofing performance during long-term use, resulting in relatively weaker overall safety and reliability.
