01 Basic meaning of BIPV

BIPV stands for Building Integrated Photovoltaic, the abbreviation of "Building Integrated Photovoltaic" in English. It is a technology that integrates solar power (photovoltaic) products into buildings. It originated in the 1960s, and then benefited from the popularization and development of the photovoltaic industry and the society's attention to carbon emission reduction in the construction industry, BIPV gradually became one of the important application technologies in the field of green buildings.

Building integration of photovoltaics can be divided into two categories: one is the combination of photovoltaic arrays and buildings; the other is the integration of photovoltaic arrays and buildings. Such as photovoltaic tile roofs, photovoltaic curtain walls and photovoltaic lighting roofs. In these two ways, the combination of photovoltaic array and building is a common form, especially the combination with building roof.

02 System overview

BIPV rooftop photovoltaic mounting solution is an application method that integrates solar power generation into buildings, realizing the perfect combination of photovoltaic power generation and buildings. This photovoltaic technology combines the application of architectural art, using photovoltaic materials to replace traditional building materials, installed on the outside of walls, roofs, etc., making the building itself a source of electricity, making full use of the building area, enhancing the aesthetic value, saving 30% The above electricity costs, extend the service life of the roof to more than 25 years, optimize the energy consumption structure of the enterprise, etc.

With its extensive commercialization and high demand for urban development, BIPV has become an inevitable choice for the transformation and upgrading of integrated photovoltaic power generation in industrial and commercial buildings.

03 The advantages of BIPV

(1) Clean energy, green environmental protection, reduce carbon emissions

Combining photovoltaic power generation with buildings can make buildings more energy efficient, and the surface of buildings can be used to generate electricity.

(2) Helps to reduce construction costs and make buildings more technological

Through photovoltaic and building integration, construction costs can be greatly reduced. After all, due to the use of photovoltaic accessories, the original curtain wall or other surface buildings on the facade of the building are replaced by photovoltaic module products with safety guarantee.

(3) Meet the lighting requirements of the building, which is safer than installing photovoltaic panels directly;

When installing photovoltaic panels directly, it is necessary to consider how to fix the photovoltaic panels on the top or side of the building. The additional accessories will always bring corresponding safety problems. After all, the additional photovoltaic modules, which have their own weight, also need to be considered on how to fix them on the top or side of the building.

(4) It can effectively reduce building energy consumption and realize building energy saving

The combination of photovoltaics and buildings will reduce building energy consumption, because the integration of photovoltaics and buildings is an optimization and scientific utilization process for the exterior of buildings.

(5) Meet the requirements of architectural aesthetics and improve its practical value and aesthetic value

The carefully designed BIPV fully meets the requirements of architectural aesthetics. It not only improves the practical value, but also has a sense of technology and the atmosphere of the times in terms of aesthetic value.

(6) Electricity bills can be reduced and the increase in energy costs can be minimized

(7) Reduce the temperature rise of the wall and roof, significantly improve the thermal insulation performance of the roof, and reduce the use of indoor refrigeration equipment

The BIPV used on the roof will strengthen the thermal insulation performance of the roof, so it can improve the thermal insulation performance of the roof, and can also play a better role in maintaining the indoor temperature.

(8) Can be combined with batteries to store electrical energy

BIPV combined with energy storage battery can store electric energy and is more convenient for emergency use.

04 The difference between BIPV and BAPV

The concept of BAPV (Building Attached Photovoltaic) is mainly to differentiate it from BIPV. In fact, BAPV refers to a rooftop distributed power station, a simple variant of which has been developed for many years.

The biggest difference between BIPV and BAPV is the deep integration of photovoltaics and architecture. Essentially, BAPV has more prominent power station attributes. Although BIPV modules have photovoltaic power generation properties, their basic properties are a building material. Therefore, apart from power generation performance, building standards and property rights division are the main issues faced by BIPV.

However, due to the prominent properties of building materials of BIPV, its application scenarios in construction are also relatively rich. In addition to flat roofs, sloping roofs, and curtain walls that can also be used by BAPV, BIPV photovoltaic support systems can also be installed in transparent lighting roofs, sun visors and other application scenarios. From the point of view of product characteristics, BIPV has clear advantages over new construction in terms of cost and aesthetics. For existing buildings, BAPV and BIPV have their own advantages and share the market.

05 Application areas of BIPV

BIPV is mainly used for building enclosures or exterior walls, awnings for building parking lots, roofs for sloped-roof buildings, and roofs for large buildings. It can also be used for personal residences, commercial buildings, schools, hospital buildings, airport subway stations, platform buses, and also for large factory and workshop exterior walls.

With the continuous maturity of photovoltaic power generation technology, the continuous improvement of photovoltaic glass tempering technology, and the running-in of component factories and building materials factories, in the long run,BIPV is a decisive development direction in the field of photovoltaic building integration.In recent years, with the continuous decline of the cost of photovoltaic modules, the era of grid parity has come, and the economy of BIPV is prominent.

06 Common advantages of BIPV system

(1) Waterproof and sturdy

The new structure is waterproof, equipped with a water guide, lower maintenance cost and longer life.

(2) Easy to install

Most of the brackets are pre-installed in the factory, and there is no need for cutting and welding on site. The installation can be completed only by tightening the bolts. The construction is fast and the later maintenance is convenient.

(3) The best benefit

It saves the cost of laying and renovation of the roof, greatly reduces the construction cost, extends the service life of the roof to more than 25 years, waterproof and heat insulation, and adds double protection.

(4) Translucent and beautiful

The arrangement of the system can be flexibly adjusted according to the actual situation of the building, adapting measures to local conditions, effectively improving indoor brightness, enhancing lighting, and perfectly integrating with the building, making the building look high-end and atmospheric.
