Building-Integrated Photovoltaics (BIPV) product series: The "Green New Clothes" for buildings

China Merchants Group is committed to empowering the transformation and upgrading of traditional construction through technological innovation, vigorously cultivating and developing new productive forces, promoting the systematic and large-scale application of scientific and technological achievements of various innovative entities in the building industry, promoting the deep integration of technological innovation and industrial innovation towards the direction of "productization, industrialization, and marketization", striving to create a second high-quality development growth curve, and better serving the people's yearning for a better life.

 

Recently, the first batch of industrialized promotion product list of China Construction was released, including China Merchants Group's "Building Good Houses", a total of 11 major products. Today, let's take a look at the Building-Integrated Photovoltaics (BIPV) series of products that "harmoniously integrate energy utilization with building aesthetics".

Building-Integrated Photovoltaics (BIPV) product series

In the field of building photovoltaics, we often hear about two similar concepts: BAPV and BIPV:

 

BAPV (Building-Applied Photovoltaics)

Like putting a "hat" on a building, traditional photovoltaic panels are installed on the roof or walls with brackets, separate from the building structure, which may affect the appearance.
 

BIPV (Building-Integrated Photovoltaics)

Like implanting a "photosynthesis" system into a building, the components themselves are building materials (such as curtain walls, roofs), combining power generation and building material functions, and perfectly integrating into the building design.

 

In short, BAPV is "add-on equipment", while BIPV is "inherent skin". Among them, the LIGHT series is a typical representative of BIPV technology.

LIGHT series: The "Green New Clothes" for Buildings

In the field of building-integrated photovoltaics, there is a new type of product that not only allows buildings to "generate their own electricity" but also achieves perfect integration with the building's appearance, with a service life of up to 25 years. This is the LIGHT series of lightweight simulation photovoltaic components independently developed by Far East Photovoltaic Technology Co., Ltd., a subsidiary of China Construction Industry Group. Creating "green new clothes" for buildings, harmoniously integrating energy utilization with building aesthetics, and making every building a "power plant" of clean energy, China Construction Industry has conducted in-depth exploration in reconstructing the building energy ecosystem and launched three innovations:

 

Material Innovation

A "super coat" as light as a feather: The combination of aviation-grade materials and ultra-thin glass ensures strength while achieving a "light as a feather" texture, as if draping the building in a strong yet lightweight "super coat".

 

Simulation Breakthrough

The "top makeup artist" of architectural aesthetics: The outdoor colored glaze process precisely replicates the texture of stone and aluminum plates, making the photovoltaic components the "second skin" of the building's exterior wall. This process uses a unique glaze formula and screen printing technology, not only achieving 99% similarity in texture to natural stone but also optimizing light transmittance, allowing the components to present the same light and shadow effects as real building materials in sunlight.
 

Efficiency Upgrade

The "invisible engine" of energy conversion: Achieving high conversion efficiency, making the annual power generation per square meter of components equivalent to planting 12 fir trees. This battery, like a "power-generating heart" hidden inside the components, converts more sunlight into electricity by optimizing silicon crystal arrangement and packaging technology.
 

In a smart community in Shanghai, the energy network built by LIGHT components makes the building an energy hub:

 

Residential buildings generate their own electricity, and excess electricity is fed into the grid, reducing the community's comprehensive energy cost by 40%.
 

Photovoltaic curtain walls and electric vehicle charging piles work together to create a "building-transportation" energy closed loop.

 

A blockchain-based energy trading platform makes green electricity transactions between neighbors possible.

 

The LIGHT series components make buildings not only shelters from wind and rain but also "self-sufficient" and even "give back to society," making them energy production units, carbon emission calculators, and urban ecological nodes. To date, Far East Photovoltaic Technology Co., Ltd. has participated in the compilation of 4 standards, including "Technical Standards for Building-Integrated Photovoltaics," "Testing Methods for Solar Heat Coefficients of Building-Integrated Photovoltaic Components," "Fire Prevention Regulations for Photovoltaic Buildings," and "Evaluation Standards for Healthy Building Living Environments," and 1 local standard collection, "Shenzhen Housing and Construction Bureau's Add-on Elevator Collection," which will further standardize the application of photovoltaic components on building facades. It has been authorized 24 invention patents and 20 utility model patents. In the future, when buildings begin to actively embrace energy, our cities will usher in a greener, smarter, and more sustainable tomorrow.
