Publish Time: 2025-04-09
At a time when global climate change and energy crisis are becoming increasingly severe, energy conservation and emission reduction have become the core issues of development in various industries. As a major energy consumer and carbon emitter, the green transformation of the construction industry is crucial to achieving global sustainable development goals. As an innovative green building technology, the crystalline silicon photovoltaic building integrated (BIPV) system perfectly integrates photovoltaic power generation with building envelope structures, which not only improves the energy self-sufficiency of buildings, but also gives buildings unique aesthetic value, becoming a new favorite in the field of energy conservation and emission reduction.Product features of crystalline silicon photovoltaic building integrated system(I) Double glass module designThe crystalline silicon BIPV system uses double glass modules, which has significant advantages over traditional single glass modules. The double glass module consists of two layers of glass and a photovoltaic cell in the middle. The transparency and light transmittance of the glass can be customized according to actual needs, which not only ensures the power generation efficiency of the photovoltaic cell, but also meets the requirements of building lighting. At the same time, the double glass module has higher strength and weather resistance, can resist the erosion of severe weather conditions, and extend the service life of the photovoltaic system. In addition, the fireproof performance of the double-glass module is also better, providing a strong guarantee for building safety.(II) Customized frame structureThe frame of the system adopts a customized cross-section design, with the left and right frames as fixed frames, the upper frame as the bottom frame, and the lower frame as the cover frame. This design not only enhances the overall stability of the photovoltaic module, but also realizes the upper and lower waterproof structure of the photovoltaic module. After installation, the cover frame of the upper photovoltaic module covers the bottom frame of the lower photovoltaic module, effectively preventing rainwater from seeping in from the gap of the module. At the same time, the left and right fixed frames are installed on the drainage trough, and the BIPV photovoltaic module is fixed to the drainage trough with a pressure block, realizing the left and right waterproof structure of the photovoltaic module. This unique frame design makes the entire system unnecessary to glue on site, greatly simplifies the installation process and improves construction efficiency.(III) Efficient waterproof mechanismIn addition to the upper, lower, left and right waterproof structures, waterproof covers are also used at the left and right gaps of the photovoltaic module for secondary waterproofing. This multi-level waterproof design ensures the waterproof performance of the BIPV system under various severe weather conditions. Whether it is heavy rain, heavy snow or strong wind, the system can operate stably, and the power generation efficiency will not be affected or safety hazards will not be caused by rainwater infiltration.Functional performance of crystalline silicon photovoltaic building integrated system(I) Replacement of traditional roof materialsCrystalline silicon BIPV photovoltaic system is widely used on the tops of buildings such as homes, industrial and commercial factories, carports, etc., replacing the color steel tiles, roof tiles and other materials used in traditional roof construction. These traditional materials not only consume a lot of natural resources for production, but also produce a lot of carbon emissions during the production process. The BIPV system achieves energy self-sufficiency through solar power generation and reduces dependence on traditional energy. At the same time, the service life of photovoltaic modules is more than 25 years, which far exceeds the service life of traditional roof materials, reducing the cost of building maintenance.(II) Reduce energy consumptionThe BIPV system provides clean and renewable energy for buildings through solar power generation. In home applications, the system can meet the daily electricity needs of the family, such as lighting, air conditioning, television, etc., reducing the family's dependence on the power grid and reducing electricity bills. In industrial and commercial plant and carport applications, the system can provide power support for production equipment and vehicles, reducing the operating costs of enterprises. In addition, the BIPV system can also be combined with the building energy storage system to realize the storage and dispatch of electricity, further improving energy utilization efficiency.(III) Reduce carbon emissionsThe use of traditional energy is one of the main causes of global climate change. The crystalline silicon BIPV system reduces the consumption of fossil fuels through solar power generation, thereby reducing the emission of greenhouse gases such as carbon dioxide. According to statistics, a typical household BIPV system can reduce carbon dioxide emissions by about 2-3 tons per year, which is equivalent to planting 100-150 trees. In the application of industrial and commercial plants and carports, the emission reduction effect of the system is more significant, which is of great significance for promoting enterprises to achieve green transformation and fulfill social responsibilities.(IV) Improve the aesthetics of buildingsThe crystalline silicon BIPV system not only has the function of energy saving and emission reduction, but also gives the building a unique aesthetic value. Photovoltaic modules can be customized according to the architectural style, and the color, shape and transparency can be adjusted according to needs. This allows the BIPV system to be perfectly integrated with the building and improve the overall aesthetics of the building. At the same time, the installation of photovoltaic modules can also increase the three-dimensional and layered sense of the building, making the building more modern and technological.Market application and prospects of crystalline silicon photovoltaic building integrated system(I) Market applicationAt present, crystalline silicon BIPV system has been widely used worldwide. In the field of households, more and more families are beginning to install BIPV systems to enjoy the convenience and economic benefits brought by solar power generation. In the field of industrial and commercial plants and carports, BIPV systems have also become an important choice for corporate green transformation. For example, some large industrial enterprises have achieved energy self-sufficiency, reduced operating costs, and obtained green subsidies and tax incentives from the government by installing BIPV systems.(II) Market prospectsWith the global attention to renewable energy and green buildings, the market prospects of crystalline silicon BIPV system are very broad. On the one hand, the support of government policies provides a strong guarantee for the development of BIPV system. Governments of various countries have introduced policies to encourage the development of renewable energy and provide subsidies and tax incentives for the installation of BIPV systems. On the other hand, the continuous advancement of technology and the reduction of costs have also made BIPV systems more competitive. With the continuous advancement of photovoltaic technology, the conversion efficiency of BIPV system continues to improve and the cost is gradually reduced. In the future, with further technological breakthroughs and the application of large-scale production, the cost of BIPV systems is expected to be further reduced, and the market penetration rate will be further improved.Technical challenges and solutions for crystalline silicon photovoltaic building integrated systems(I) Technical challengesAlthough crystalline silicon BIPV systems have many advantages, they still face some technical challenges in practical applications. For example, the power generation efficiency of photovoltaic modules is greatly affected by weather conditions, and power generation cannot be achieved in rainy weather and at night; the installation and maintenance of the system requires professional technicians to operate, which increases the difficulty and cost of construction; in addition, the long-term performance stability and reliability of the BIPV system also need to be further verified.(II) SolutionsIn response to these technical challenges, the following solutions can be adopted. First, improve the power generation efficiency of photovoltaic modules through technological innovation. For example, research and development of new photovoltaic materials, optimization of photovoltaic cell structure, and improvement of the light transmittance of photovoltaic modules. Secondly, strengthen technical training and talent training, improve the professional level of construction personnel, and reduce construction difficulty and cost. In addition, a complete after-sales service system can be established to regularly maintain and overhaul the BIPV system to ensure the long-term performance stability and reliability of the system.Crystalline silicon photovoltaic building integrated system has become a new favorite in the field of energy conservation and emission reduction due to its unique product characteristics and excellent functional performance.
