Roofing and installation of photovoltaic building capacity testing and identification professional unit - Huaqiang Electronic Network

**Photovoltaic Roof Load Detection and Identification Services** The roof is equipped with a professional unit for the detection and identification of photovoltaic buildings. As the distributed photovoltaic market continues to grow rapidly, idle roof spaces have become an important resource for solar power generation, especially in industrial and commercial sectors. These roofs are not only valuable but also essential for reducing energy consumption and maximizing the use of existing assets. By installing photovoltaic systems on the rooftops of underutilized charging stations, companies can significantly cut down on energy costs while contributing to national efforts in energy conservation and emission reduction. This approach not only brings economic benefits but also supports sustainable development. Shenzhen Zhongzheng Engineering Technology Co., Ltd. specializes in providing comprehensive photovoltaic load detection and appraisal services. Our company has advanced technology, experienced engineers, and a well-established management system. We offer free technical consultation and support to ensure that every project meets safety and performance standards. **Why is Photovoltaic Load Testing Important?** Over time, buildings may experience wear and tear due to natural aging, overuse, or nearby construction activities. These factors can lead to structural damage, potentially causing serious safety hazards. Regular inspections are crucial, especially during stormy seasons, to identify issues early and prevent accidents. **Understanding Building Structures** A building's structure typically consists of foundations, columns, beams, and walls. Common residential structures include: - **Frame Structure**: Made of reinforced concrete columns, beams, and slabs. - **Mixed Structure**: Combines brick walls (or columns) with concrete slabs. - **Brick-Wood Structure**: Uses brick walls (or columns) along with wooden trusses. Among these, mixed and brick-wood structures are more prone to safety risks. According to statistics, 81% of collapsed houses were of these types, emphasizing the need for regular assessments. **Key Steps in Photovoltaic Load Detection** To ensure safe installation of solar panels on rooftops, the following steps are essential: 1. Review of building construction and design. 2. Examination of floor plans and structural details. 3. Evaluation of current building usage. 4. On-site inspection of structural conditions. 5. Strength testing of main materials. 6. Measurement of structural deformation. 7. Analysis of structural safety. 8. Issuance of a detailed safety report. **Case Study: Steel Structure Factory Building** In a two-story steel structure factory, the foundation was rated as Class A with no signs of subsidence. The upper structure, including steel frames and supports, was found to be in good condition, meeting all safety requirements. The overall structure was rated as Class A, confirming its suitability for photovoltaic installation. **Challenges in Rooftop PV Installation** While concrete roofs generally handle the weight of solar panels well, steel roofs require careful evaluation. The live load capacity of steel structures is often lower, making it critical to assess the roof’s ability to support additional weight. For example, in southern regions, the typical live load is around 0.5 kN/m², which may not be sufficient when adding photovoltaic panels. **Safety Measures for Distributed PV Systems** To ensure the safety of distributed photovoltaic systems, several precautions should be taken: - Conduct thorough space planning to avoid unauthorized access to equipment. - Choose products from reputable manufacturers to guarantee quality and reliability. - Implement fire protection, grounding, and wind resistance measures. - Regularly inspect and maintain the system to detect and resolve potential issues early. **Our Commitment to Quality and Safety** At Shenzhen Zhongzheng Engineering Technology Co., Ltd., we are committed to delivering accurate, reliable, and impartial testing and appraisal reports. Our team of experts ensures that each project meets the highest standards of safety, efficiency, and compliance. We believe in transparency, professionalism, and continuous improvement to serve our clients and the community effectively.
