The mounting structure of the PV array bracket should be simple and durable. The materials used to manufacture the PV array brackets must be able to withstand the erosion and various corrosion of wind and rain. Electroplated aluminum profiles, galvanized steel and stainless steel are ideal choices. The welding quality requirements of the brackets must meet the requirements of the national standard 'Code for the Acceptance of Construction Quality of Steel Structures'. The array brackets are designed to be lighter in weight for design and transport. In the construction process of the photovoltaic array foundation and the support, the damage to the relevant buildings and ancillary facilities should be avoided as much as possible. If the construction needs to cause partial damage, it should be repaired in time after the completion of the construction.
When installing the PV array on the roof, the pedestal embedded parts should be firmly welded or connected with the steel bars of the roof main structure. If it is not possible to weld or connect due to structural constraints, measures should be taken to increase the adhesion between the pedestal and the roof. It is fixed by wire tensioning or stent extension. After the pedestal is completed, it shall be waterproofed to the roof damage or in accordance with the requirements of the National Standard 'Tall Engineering Quality Acceptance Specification' to prevent water seepage and rain leakage.
The PV module frame and bracket should be reliably connected to the grounding system. First fix the bracket on the roof, then mount the solar module on the bracket and bolt the assembly. v Pass the screws through the flat washers, the mounting holes of the assembly and the bracket frame. The screw passes through the flat washer and spring washer and then the nut is tightened at the end. The bracket should be durable and corrosion resistant for 20 years. High temperature galvanized steel and stainless steel are preferred. The robustness of the bracket should be able to withstand the constant load, wind, snow, earthquake pressure and other external forces.
