Introduction: BIPV system integrators, with high technical barriers, include photovoltaic and construction firms. The former sells custom BIPV products and handles integration, while the latter, leaders in building sectors, focus on enclosures and structures. With the push for carbon neutrality, relying only on photovoltaic roofs is insufficient. Future BIPV will extend beyond roofs to building facades, meeting evolving electricity needs.
What is BIPV
BIPV generally refers to building integrated photovoltaics. It is a technology that integrates solar power generation (photovoltaic) products into buildings. Simultaneously, it serves as a functional part of the building structure, replacing certain traditional architectural elements such as roofs, building facades, canopies, and more.
① PV Roof
The PV roof integrates solar panels with the roof structure, generating electricity while providing waterproofing and insulation. It serves as the primary BIPV power source, ideal for residential and commercial buildings.
② PV Fence
The PV fence combines fencing and solar power generation, offering both boundary separation and green energy supply. It’s aesthetically pleasing and functional, suitable for courtyards, balconies, and industrial perimeters.
③ PV Shade
The PV shade provides shading, rain protection, and solar power generation. It’s ideal for carports, balconies, or leisure areas, reducing building energy consumption while promoting energy self-sufficiency.
④ PV A-side Curtain Wall
The PV A-side curtain wall integrates high-efficiency solar glass into the building façade, enhancing architectural aesthetics while converting sunlight into electricity to improve energy performance.
⑤ PV Wall
The PV wall embeds solar modules into the wall structure, combining enclosure and power generation. Its modular design allows easy installation and maintenance, supplying clean energy around the building perimeter.
Types of BIPV
There are many types of building-integrated photovoltaics (BIPV). They are classified differently according to battery type, application scope, and product appearance. The following are some common BIPV types:
PV Roof Panel
The PV Tile Roof System, replacing the traditional combination of PV panels and brackets, adopts an appearance identical to regular tiles. Utilizing flat photovoltaic tiles, it seamlessly integrates with the architecture.
Transparent PV Curtain wall/ Roof tile
Sunlight-penetrating photovoltaic glass, suitable for greenhouses and sunrooms.
Photovoltaic Curtain Wall Facade
Colored photovoltaic curtain wall panels, designed to be aesthetically pleasing and harmonious, not only provide energy-saving functionality but also impart a modern and distinctive appearance to the building.
Thin-film solar cell:
CdTe(Cadmium telluride) transparent power-generating clear PV glass
This technology involves incorporating a thin film within the glass, with the CdTe thin layer designed to capture and convert solar photons into electrical energy.
CIGS Flexible Module
CIGS refers to Copper, Indium, Gallium, and Selenium. This is a thin-film solar cell technology that involves applying this compound to a flexible substrate to create photovoltaic modules.
Unlike traditional silicon-based solar cells, CIGS technology can produce thinner, lighter and more flexible photovoltaic modules. This makes CIGS flexible components ideal for applications with curved or irregular surfaces, such as curved facades, roofs, or other non-traditional solar scenarios in buildings.
