Building Integrated Photovoltaics

Building Integrated Photovoltaics

Building Integrated Photovoltaics (BIPV) has enormous advantages, including green energy saving, reduced carbon emissions, enhanced building aesthetics, replacement of some building materials, reduced building costs, improved power efficiency, land resource saving, reduced air and solid waste pollution, and ecological protection. Developing BIPV is of great significance for building decarbonization.

 

 

PART ONE

What is Building Integrated Photovoltaics

- What is Building Integrated Photovoltaics -

 

 

Building Integrated Photovoltaics (BIPV) is a technology that integrates solar photovoltaic products into buildings, becoming an inseparable and fully integrated part of the building. That is, solar cells are used as building elements in design and construction, becoming building material-type photovoltaic components (photovoltaic tiles, photovoltaic glass, photovoltaic integrated roof products). Photovoltaic components will perform building functions such as wind protection, rain protection, sound insulation, and heat insulation; removing the photovoltaic components will eliminate these functions.

BIPV is different from BAPV (Building Attached PV). BAPV refers to a technology where the photovoltaic system is attached to the building, combining with the building but remaining independent. Its main function is power generation; removing the photovoltaic components will not affect the building's function.

What are the advantages of BIPV

- What are the advantages of BIPV -

Because photovoltaics are a component of the building, the building can continuously generate green electricity. Integrated with the building, building photovoltaics can become a building material with a return on investment, possessing the functions of building materials.

 

1

Decorative wall surfaces, unified aesthetics

BIPV photovoltaic power generation components can serve as part of the wall, playing a decorative role. The solar energy facility components and the building merge into one, forming a reasonable structure and a complete, coordinated, and unified building appearance.

 

2

Wind and rain protection, snow and wind protection

BIPV photovoltaic power generation components can be applied to roofs or exterior walls. Like ordinary glass curtain walls, they have functions such as rain and light protection, snow and wind protection, and can be used in platforms, parking sheds, awnings, and bus stops.

 

 

3

Light transmission

Unlike traditional photovoltaic components, natural light can pass through BIPV components into the room. It can be used in large curtain wall lighting tops.

Sound insulation and heat insulation

BIPV photovoltaic power generation components are mostly double-glass laminated components. To improve the sound insulation and heat insulation of buildings, hollow laminated power generation components can be used.

PART THREE

Future trends of BIPV

- Future trends of BIPV -

After several years of development, BIPV photovoltaic power generation components can meet customizable light transmission, color, and shape requirements, and their application scenarios are very wide.

It is estimated that in 2025, the incremental and stock markets of photovoltaic buildings will generate a total market space of over 423.5 billion yuan, and the overall penetration rate of BIPV will rapidly approach 20%, generating a total market space of over 86.6 billion yuan in 2025. The distributed photovoltaic market, especially the BIPV market, has great potential.
