Although the photovoltaic bracket is not the core part of the photovoltaic system, it can indeed guarantee the basis for the normal and stable operation of the system, so the requirements for it are very strict. The first thing that bears the brunt is the requirements for the materials for the production of photovoltaic stents, such as a series of performance characteristics that can be used to make photovoltaic stents.
Since it is to be used to make photovoltaic supports, the material must have high tensile strength and yield point, because only a higher yield point can reduce the section of steel components, increase the weight of the structure and save steel, thereby reducing it to a certain extent The cost of photovoltaic stents. The high tensile strength can ensure its overall stability, making the photovoltaic support more reliable.
Secondly, the material of the photovoltaic stent should also have excellent plasticity, toughness and fatigue resistance. With better plasticity, the stent can be deformed significantly before damage, so as to remind people to take remedial measures in time; at the same time, it is convenient to adjust the peak stress. . The better toughness can make the photovoltaic bracket maintain stability when it is subjected to external force and load; better fatigue resistance can also make the photovoltaic bracket have a strong resistance.
In addition, processing performance is also necessary as a material for photovoltaic stents, including many requirements such as cold processing performance, thermal processing performance, and solderability. Since the service life of the photovoltaic system is expected to reach more than 20 years, the application life of the photovoltaic support material must also reach such a standard, thereby improving its economic benefits.
In the case of meeting the above conditions, the material sources of photovoltaic brackets should also be as wide as possible, so as to have more advantages in price than scarce materials, and to reduce the manufacturing cost of photovoltaic brackets to a certain extent.
