pv and architectural integration: Exploring the role of BIPV PV mounting systems in green buildings

BIPV system overview and mounting role positioning
BIPV (building integrated pv) is to use pv modules directly as part of the building structure or building surface materials, and use them in building shell systems such as roofs, facades, sunshades, and window sheds to achieve the integration of building and pv functions. Compared with traditional pv systems, BIPV not only has the ability to generate electricity, but also takes into account the building function and aesthetic effect.
In the BIPV system, the mounting system undertakes multiple tasks of load-bearing, fixing, drainage, anti-seepage and appearance coordination, and is the core structural link between pv modules and buildings. Therefore, BIPV PV mountings not only need to have structural mechanical properties, but also need to meet comprehensive requirements such as building beauty, sealing performance, and thermal expansion matching.

Typical structural forms of BIPV PV mountings
Due to different installation locations and usage scenarios, the common structural forms of BIPV PV mountings mainly include:
*Embedded frame structure: suitable for curtain wall and roof laying, pv modules are embedded in aluminum alloy frames, and the caulking parts are pressed with sealants or pressure strips to form a continuous building surface.
*Keel-type mounting structure: pv modules are mounted through vertical or horizontal keel systems, with strong structural adaptability, and are often used in pv facades or large public buildings.
*Sealing layer downward pressure structure: used in building roofs or balconies, the upper pressure plate and pressure strip structure are used to clamp the pv modules, and used in conjunction with drainage channels, with certain waterproof and dustproof capabilities.
*Glass-glass component direct mounting structure: high-strength aluminum profiles and pressure strip structures are used to directly combine double-glass modules with buildings to improve the overall consistency of the system.
These mounting structures must be customized according to the specific building load, wind pressure, rain and snow conditions and building facade design.

Selection and durability requirements of mounting materials
The selection of materials for BIPV mountings must meet the strength and durability requirements, as well as the appearance and environmental adaptability. Common materials include:
*Aluminum alloy profiles: widely used in curtain wall and roof systems, light weight, strong corrosion resistance, and adaptable to a variety of structural designs.
*Stainless steel components: used for connectors, fixtures and special parts, with good tensile strength and weather resistance.
*Steel structure substrate: used in some large-span roofs or steel structure buildings, the mounting strength is higher, but the surface anti-corrosion treatment is required, such as hot-dip galvanizing or spraying.
Material selection needs to be adapted according to the climate characteristics of the building area. For example, it is advisable to choose a combination of aluminum alloy and stainless steel in coastal high salt fog areas.

Fusion design with building functions
In the design process, the BIPV PV mounting system not only considers the mechanical structure, but also emphasizes the deep integration with the building function, which is mainly reflected in the following aspects:
*Waterproof performance: Roof or facade pv systems need to achieve water seepage control through structural drainage, sealants, double-line defense and other measures;
*Insulation and ventilation: Some pv curtain walls adopt back ventilation design, and the mounting system needs to leave ventilation cavities to mitigate the heat island effect;
*Architectural beauty: The pv components and mountings must conform to the overall effect of the building facade in terms of color, spacing, and splicing form;
*Thermal expansion adaptation: The thermal expansion coefficients of metal and glass materials are quite different, and the mounting needs to consider floating connection or flexible pressure plate design.
Taizhou Dongsheng New Energy Technology Co., Ltd. provides a highly adaptable BIPV mounting system through customized design solutions in actual projects, combined with architectural drawings, structural stress analysis and on-site environment.

Construction and installation process requirements and supporting standards
The installation of the BIPV mounting system is more complicated than that of ordinary pv mountings, and must comply with the dual requirements of building construction specifications and pv system wiring specifications:
* Embedded parts layout: Curtain walls and roof systems are often connected to the main structure through embedded parts, and measurement and positioning are required before installation to avoid deviation;
* Component hoisting and fixing: The mounting must have a positioning and guiding function, and soft connection buffering is used during component hoisting to avoid damage;
* Sealing treatment: All interfaces must use waterproof sealing strips or silicone edge sealing to prevent rainwater from penetrating into the building structure;
* Cable laying channel: Cable channels or wiring space are reserved in the mounting structure to facilitate later maintenance and system upgrades.
During the installation process, the orientation, inclination and ventilation spacing of pv components must be considered simultaneously to obtain reasonable power generation efficiency and building integration effects.

System economy and life cycle management
The initial construction cost of the BIPV mounting system is slightly higher than that of ordinary pv systems, but it can replace some building materials and has the potential to save the cost of exterior walls and roof finishes. At the same time, the system has strong long-term profitability:
* Save building material expenditure: replace traditional decorative materials such as glass, aluminum plates, tiles, etc.;
* Energy saving and consumption reduction: some BIPV structures can play a role in shading and heat insulation, reducing the energy consumption of building air conditioning;
* Comply with green building standards: can help construction projects obtain LEED, Green Building Three Star and other certification points;
* Convenient later operation and maintenance: The standardized module design of the mounting can realize the rapid replacement and maintenance of components.

BIPV PV mounting system construction and building integration practice

Definition and development background of BIPV PV mounting system
BIPV (Building Integrated Photovoltaics) is a form of pvapplication that directly integrates pvmodules into buildings as building components. Its mounting system is an important basis for the overall structural safety, functional realization and building integration. With the in-depth development of the concept of green building, BIPV systems are widely used in building structures such as curtain walls, roofs, sun sheds, skylights, etc., which puts forward higher requirements on the structural strength, aesthetics, and installation convenience of the mounting system.
Taizhou Dongsheng New Energy Technology Co., Ltd. has been focusing on the overall solution of distributed pvsystems since 2009. It has continuously invested in research and development in the field of BIPV PV mounting systems and accumulated experience in mounting customization and engineering practice for different types of buildings.

Core structural features of BIPV PV mounting
The main difference between BIPV mounting systems and traditional pvmounting systems is that they must have the basic functions of building components, such as wind and rain protection, fire protection, load bearing and sealing. To meet these requirements, BIPV mounting design usually pays more attention to the following points:
*Sealing and drainage function: A reasonable drainage slope and drainage trough structure must be set in the system to prevent rainwater leakage.
* Load-bearing structure optimization: The mounting system must not only bear the weight of the pvmodules, but also cooperate with the overall load distribution of the building structure.
* Various installation methods: including snap-on, plug-in and slide rail types, which are easy to install and maintain quickly.
* Considering both aesthetics and consistency: It is usually necessary to customize it in combination with the appearance of the building to meet the overall aesthetic requirements.
Dongsheng New Energy's design team incorporates the modular concept into the BIPV structure, improves the overall assembly efficiency and simplifies maintenance through precision processing and standardized components.

Material selection and durability control
In the BIPV mounting system, the weather resistance and mechanical properties of the material directly affect the operating stability of the overall system. Commonly used materials include aluminum alloy, stainless steel and galvanized steel:
* Aluminum alloy: has good corrosion resistance and processing flexibility, suitable for roof and facade structures.
* Stainless steel: Suitable for areas with high wind loads or stricter corrosion resistance requirements, such as coastal projects.
* Galvanized steel: moderately priced, suitable for curtain wall systems with less stringent weight requirements.
Taizhou Dongsheng New Energy Technology Co., Ltd. will optimize and recommend materials based on the specific needs of the project and climatic conditions to ensure that the mounting system has long-term durability and economic controllability.

Typical application scenarios and structural solutions
BIPV pvmounting systems can be divided into several typical solutions according to different building structure applications:
*Glass curtain wall system: pvmodules are embedded in the building facade as part of the curtain wall glass. The mounting system is usually hidden, focusing on structural strength and visual integration.
*Sloped roof system: pvmodules are integrated with tiles or cement roofs through aluminum rails or hooks, with sealing, waterproofing and other requirements.
*Sun shed system: suitable for commercial buildings or residential balcony areas, the mounting needs to consider the ratio of span and light transmittance.
*Lighting roof system: combined with skylights, it provides indoor lighting and realizes power generation function. The mounting needs to have high anti-seepage performance.
