BIPV Building Integrated PV (PV is Photovoltaic) is a technology that integrates solar power generation (photovoltaic) products into buildings. BIPV is different from the form of building attached PV (BAPV).

Building integration of photovoltaics can be divided into two categories: one is the combination of photovoltaic arrays and buildings. The other type is the integration of photovoltaic arrays and buildings.

Such as photoelectric tile roof, photoelectric curtain wall and photoelectric lighting roof, etc. In these two ways, the combination of photovoltaic array and building is a commonly used form, especially with the building roof.

According to the different ways in which the photovoltaic array is combined with the building, the solar photovoltaic building integration can be divided into two categories:

The first type is the combination of photovoltaic arrays and buildings. In this way, the photovoltaic array is attached to the building, and the building acts as the carrier of the photovoltaic array and plays a supporting role.

The second type is the integration of photovoltaic arrays with buildings. In this way, photovoltaic modules appear in the form of a building material, and the photovoltaic array becomes an integral part of the building.

The combination of photovoltaic arrays with buildings (i.e., the first type) is a commonly used form. In the 2008 Olympic Games, the National Aquatics Center and the National Stadium and other Olympic venues used the solar photovoltaic grid-connected power generation system that combines the photovoltaic array and the building, and the annual power generation capacity of these systems can reach 700,000 kilowatt hours, which is equivalent to saving 170 tons of standard coal and reducing carbon dioxide emissions by 570 tons.

BIPV refers to the installation of photovoltaic modules on the surface of the building envelope to provide electricity. At the same time, it is a functional part of the building structure that replaces part of the traditional building structure. such as roof slabs and tile windows, building facades.

Building Integrated Photovoltaics (BIPV) refers to the installation of photovoltaic modules on the surface of the building envelope to provide electricity, and at the same time, as a functional part of the building structure, it replaces some traditional building structures such as roof panels, tiles, windows, building facades, rain shelters, etc., and can also be made into photovoltaic multi-functional building components to achieve more functions, such as photovoltaic solar thermal system, combined with lighting, combined with building shading, etc.

According to the type of installation, the construction of BIPV is divided into three types, namely, building material installation type, component installation type and installation type combined with roof and wall.

The advantages of BIPV are significant

In addition to the power generation function, the photovoltaic building transportation system also has the necessary performance and unique decoration functions of the building envelope, such as wind pressure resistance, water tightness, air tightness, sound insulation, heat preservation and shading performance, so as to achieve the perfect combination of building envelope, building energy saving, solar energy utilization and building decoration. Its advantages are mainly manifested in:

Three mainstream application forms of photovoltaic buildings

The roof of the building is the part of the building that receives the most solar radiation, and it is usually the part that is least shaded. Therefore, from the point of view of energy efficiency, roofs are the best application place for building photovoltaic integration. Vertical walls are not the best part of PV generation, but building facades tend to have more surface area to integrate PV systems.

Usually the building façade is the focus of the design, not only to express the form but also to meet the necessary functional requirements, so higher requirements are put forward for the integration of the photovoltaic system.

In addition to the above two types of photovoltaic building integration construction forms, photovoltaic shading is also a more effective building form, the purpose of building external shading is to shade direct sunlight to improve the building thermal environment, reduce building operation energy consumption, is a commonly used energy-saving measure in buildings.

Carbon neutrality promotes the development of BIPV

The 2030 Carbon Peak Action Plan points out that in terms of photovoltaic buildings, in the future, it is necessary to deepen the application of renewable energy buildings, continue to promote the application of photovoltaic power generation and building integration, and build a "photovoltaic storage, direct and flexible" building integrating photovoltaic power generation, energy storage, DC power distribution, and flexible electricity consumption, and by 2025, the photovoltaic coverage rate of new public institution buildings and new factory roofs is expected to reach 50%. Forward-looking believes that the policy is conducive to the accelerated development of the BIPV industry and brings more incremental markets.

The development of China's BIPV industry is at the forefront

According to the China Photovoltaic Industry Association, in 2020, China's installed BIPV capacity reached 709MW, and the BIPV output of some enterprises has surpassed that of Europe. In the future, with the establishment of a unified BIPV standard, the proportion of BIPV buildings will continue to increase, and according to the estimation of China's new construction area, the market size of BIPV for new buildings in China will exceed 130 billion yuan in 2021.

Photovoltaic building system refers to the installation of photovoltaic power generation on buildings. Grid-connected power generation combined with buildings is an important application form of photovoltaic power generation at present, and the technology has made rapid progress before the ascension, which is mainly reflected in the installation method combined with buildings and the electrical design of building photovoltaics.

BAPV: A photovoltaic system that uses ordinary photovoltaic modules and is installed on the original building, and does not replace building materials or building components, and is directly installed on the roof or attached to the wall. By removing the PV modules from the building, the smart limbs will not affect the basic functions of the original building.

Building photovoltaic integration is the integration of solar power generation technology, the use of solar photovoltaic materials to replace traditional building materials, so that the building itself becomes a big energy. BIPV technology is used to integrate solar cell materials into the roof and wall envelope of the building. Nuclear hail skin.
