Steel Structure Factory with Roof Solar Power System
Case Detail
Project: Integrated Steel Structure Factory with Roof Solar Power Generation System
Location: Bavaria, Germany
Year: 2024
Client: German Precision Machinery Manufacturing Co., Ltd.
Scope: Design, supply, construction and commissioning of a single-span steel structure factory, with a total area of 8,500 square meters. The entire roof is covered with solar panels to realize self-sufficient power supply and surplus power grid connection, supporting the factory's daily production and operation.
Challenge
The client needed a high-strength, durable steel structure factory to meet the production needs of precision machinery, while pursuing green and low-carbon development. Traditional factories have high energy consumption and high long-term operation costs. The client hoped to make full use of the factory roof space to install solar power generation systems, realizing energy saving and emission reduction, and reducing electricity expenses. At the same time, the project required strict control of the overall construction cycle, ensuring that the factory could be put into use on schedule, and the integration of the steel structure and solar system needed to be safe and stable without affecting the factory's normal operation and structural safety.
Solution
We provided a one-stop solution integrating steel structure design, construction and solar power system installation, combining structural stability with green energy utilization.
- The main structure adopted Q355B high-strength steel, which was prefabricated in the workshop with high precision, ensuring the overall stability and load-bearing capacity of the factory, and fully meeting the load requirements of roof solar panels.
- The roof was designed with a reasonable slope to maximize the absorption of solar energy, and lightweight and high-efficiency solar panels were selected, which not only reduced the load on the steel structure but also improved the power generation efficiency. The solar system adopted the "self-use first, surplus power grid connection" mode, which could effectively use clean energy.
- The steel structure and solar power system were designed synchronously, and the connection between the solar panel bracket and the steel structure roof was optimized to avoid roof leakage and ensure the tight integration of the two systems, while complying with relevant national technical standards for building photovoltaic systems.
Execution
The project started with design in early 2023 and was fully completed in early 2024, taking a total of one year from design to construction and commissioning. The whole process was carried out in an orderly manner: the steel components were prefabricated in the workshop with high precision to ensure the quality of parts; the on-site installation was carried out in sections, including steel frame erection, roof closure, and solar panel installation; the solar power system was debugged after the steel structure construction was completed to ensure that it could be put into use normally. The entire construction process strictly followed the relevant specifications to ensure the safety and stability of the structure and the efficiency of the solar system.
Outcome
The steel structure factory has been put into stable operation, and the solar power system on the roof has achieved good power generation effect. The generated electricity can meet more than 60% of the factory's daily production and lighting needs, and the surplus electricity can be connected to the grid to bring additional economic benefits to the client. The steel structure factory has the advantages of high stability, corrosion resistance and easy maintenance, and the integration of the solar system has effectively reduced the client's electricity costs and carbon emissions, helping the client achieve the goal of green production. The project has been highly recognized by the local environmental protection department and has become a typical example of green industrial transformation in the region.
