Photovoltaic building (BIPV) represents the deep integration of building and photovoltaic industry. It is not only a technological innovation, but also a new design concept.In this field, buildings are not only shelter from the wind and rain, but also energy collectors and producers. This paper will discuss the core elements of photoelectric building, market development logic and its important position in the future construction industry from a professional point of view.

The design and implementation of photovoltaic buildings involves several key elements, including but not limited:

• String design:Series and parallel design of photovoltaic modules to achieve the best electrical performance and power generation efficiency.

• Cable connection:Ensure safe and reasonable cable layout and meet electrical safety requirements.

• photovoltaic inverter:Select the appropriate inverter to ensure that the photovoltaic system can efficiently convert direct current to alternating current.

• Structural safety:The installation of photovoltaic modules must comply with building structural safety standards to withstand natural conditions such as wind loads and snow loads.

• Electrical safety:The electrical design of photovoltaic systems must follow the national electrical safety code.

• Fire Safety:Photovoltaic materials and systems must be designed to meet fire protection requirements to prevent fire risks.

• Lighting requirements:While ensuring the efficiency of power generation, it is also necessary to consider the demand for indoor natural lighting.

• Color matching:The color and appearance of the PV modules shall be in harmony with the overall design style of the building.

• Thermal analysis:Evaluate the impact of PV modules on the building's thermal environment and optimize the building's thermal performance.

• Architectural modeling:The integration of photovoltaic modules needs to be integrated with the architectural appearance and design.

• Exterior wall division:Reasonably plan the division of the outer wall to adapt to the installation and maintenance of photovoltaic modules.

• PV Modulus:The size and specifications of photovoltaic modules should be matched with the building module to achieve modular design.

• Photovoltaic distribution:According to the direction of the building, the surrounding environment and other factors, reasonable distribution of photovoltaic modules.

• Shadow Analysis:Assess the impact of surrounding buildings, trees, etc. that may cause shadows on the PV modules.

• Ash accumulation analysis:Consider the problem of dust accumulation on the surface of photovoltaic modules, and make a cleaning and maintenance plan.

The healthy and orderly development of the photoelectric construction market needs to be promoted from two aspects:

1. Policy support and training exchange:The government plays a vital role in promoting the development of photovoltaic buildings. By providing education and training, financial support and setting low-carbon procurement policies, a market environment conducive to the development of photovoltaic buildings can be created. In addition, relevant departments can also promote the development of life cycle analysis and low-carbon products by setting benchmarks, targets and information disclosure mechanisms.

2. Technological innovation and industry cooperation:Technological innovation is the key driving force to promote the development of the photovoltaic construction market. Investors and construction companies need to collaborate to develop innovative low-carbon/zero-carbon building materials and products. By strengthening industry cooperation and the establishment of a standardized system, the exchange and application of technology can be promoted, thereby promoting the healthy development of the entire industry.

With the increasing global demand for sustainable development and green buildings, the market prospect of photovoltaic buildings is broad. In the future, we expect photovoltaic buildings to make significant progress in the following areas:

1. Technical Breakthrough:With the advancement of material science and photovoltaic technology, photovoltaic modules will be more efficient, practical and beautiful, and can be better integrated with buildings.

2) Cost reduction:Large-scale production and technological innovation will reduce the cost of photovoltaic buildings, making them a more competitive building solution.

3. Market expansion:Policy support and market demand will drive the popularity of photovoltaic buildings worldwide, especially in urban and industrial buildings.

4. Environmental benefits:Photovoltaic buildings will significantly reduce carbon emissions in the construction industry and make an important contribution to achieving carbon neutrality.

In short, photovoltaic architecture represents the future development direction of the construction industry. It perfectly integrates architectural aesthetics, structural safety, energy efficiency and environmental responsibility, and provides the possibility of creating a more sustainable living environment. With the continuous progress of technology and the gradual maturity of the market, photoelectric building will undoubtedly become a new benchmark in the construction industry.
