Solar photovoltaic power generation system

The solar photovoltaic support device is a special support for the placement, installation and fixing of solar panels in the solar photovoltaic power generation system h beam manufacturers. The general material is aluminum alloy and stainless steel. Solar photovoltaic supports have strict requirements on steel performance, and solar photovoltaic support equipment steels should have the following properties:

1. Tensile strength and yield point. The high yield point can reduce the section of the steel member, reduce the structural weight, save steel and reduce the overall project cost. High tensile strength can increase the overall safety reserve of the structure and improve the reliability of the structure.

2. Plasticity, toughness and fatigue resistance. Better plasticity can cause large deformation of the structure before it is destroyed, so that people can find and take remedial measures in time. Better plasticity can also adjust the local peak stress. The solar panel installation itself is often used to adjust the angle, using forced installation, and plasticity can make the structure generate internal force redistribution, so that some of the original stress concentration part of the photovoltaic support structure or component The stress tends to be uniform, improving the overall bearing capacity of the structure. The better toughness can make the structure absorb more energy under the impact of external force impact load, especially the desert power station and the rooftop power station with large wind force. The wind vibration effect is obvious, and the toughness of the steel can effectively reduce the dangerous degree. Better fatigue resistance also allows the structure to have a strong resistance to alternating wind loads.

3. Processing performance. Good processing properties include cold workability, hot workability and weldability. The steel used in photovoltaic steel structures is not only easy to process into various forms of structures and components, but also requires that these structures and components do not have the adverse effects of excessive strength, plasticity, toughness and fatigue resistance due to processing.

4, the service life. Since the design life of solar photovoltaic systems is more than 20 years, good corrosion resistance is also an important indicator to measure the quality of photovoltaic support systems. If the life of the stent is short, it will inevitably affect the stability of the entire structure, resulting in an extended payback period and a reduction in the overall service life.
