Selection considerations for photovoltaic accessories
Nov 07,2024
Material: carbon steel, stainless steel and aluminum alloy are common. The appropriate material should be selected according to the corrosive environment. For example, in humid, seaside and other corrosive environments, stainless steel or carbon steel bolts and nuts with special anti-corrosion treatment should be preferred.
Specification adaptation: according to the structure and bearing requirements of the photovoltaic bracket, select the appropriate bolt and nut specifications, including diameter, length, thread type, etc. To ensure that sufficient clamping force is provided to ensure a secure connection between the bracket components.
Connector: its material and specification shall match the main material of the bracket. Ensure that the strength and rigidity of the connector can withstand the weight of the photovoltaic module and external loads such as wind and snow, and at the same time facilitate installation and disassembly to improve construction efficiency.
Anti-corrosion protection: The photovoltaic bracket is exposed to the outdoors for a long time and requires good anti-corrosion protection. When selecting anti-corrosion coatings, consider their weather resistance, corrosion resistance, adhesion and other properties.
Fire performance: in some places with fire protection requirements, such as the roof of buildings, flammable materials, etc., need to use fire retardant coating. Fireproof coatings should have good fireproof performance and be able to prevent the spread of fire within a certain period of time.
