This Solar Mounting Bracket, directly sold by Shixinda's factory, is modular prefabricated and assembled with full bolts on-site. There is no need for on-site welding, significantly shortening the construction period. The inclination angle can be adjusted from 5° to 45°, compatible with large-sized components such as 182/210. It can be combined with spiral ground anchors, roof fixtures, and counterweight bases for various foundations, and can be customized for complex terrains such as mountains, color steel roof, and fish ponds. Compared to ordinary brackets, the ventilation and heat dissipation design reduces component degradation, and the tracking model can increase power generation by 15%-30%.
As a source steel manufacturer, Shixinda independently controls the profile specifications. C-shaped steel, square tubes, and a complete set of 304 stainless steel accessories are produced and sold in-house, balancing cost performance and delivery speed. It supports custom orders for bulk export orders, and the steel can be recycled, meeting the needs of zero-carbon photovoltaic projects. It provides stable and reliable complete support solutions for domestic and foreign photovoltaic power stations.
The Solar Mounting Bracket is a specialized steel structure/aluminum alloy component system used for fixing, supporting, and bearing solar photovoltaic modules. It is equipped with connecting parts, bases, and adjustment accessories and is installed on the ground, roof, car shelter, water surface, etc. It is a core auxiliary material for photovoltaic power stations, stabilizing the photovoltaic panels at the optimal inclination and orientation to ensure their stability, and is divided into fixed type, tracking type, floating type, and roof support types.
Load-bearing and fixation: Bearing the weight of the photovoltaic panels, wind pressure, snow pressure, and seismic loads to prevent the components from overturning or falling off;
Angle optimization: Adjusting the inclination and orientation of the photovoltaic panels to maximize solar irradiation reception and improve overall power generation;
Protection and protection: Isolating the photovoltaic panels from the ground/roof, providing ventilation and heat dissipation, reducing water accumulation and snow accumulation, and delaying component aging;
Standardization and compatibility: Arranging the components uniformly, leaving a maintenance passage, facilitating cleaning, maintenance, and replacement of components;
Scene adaptability: Adapting to complex terrains such as mountains, plains, color steel tile roofs, concrete roofs, and fish ponds.
Mainly uses hot-dip galvanizing / zinc-aluminum-magnesium alloy. It has high corrosion resistance and is suitable for use in seaside, saline-alkali areas, and rainy regions. The anti-corrosion life is 25 years +, matching the lifecycle of photovoltaic modules. The power station can avoid frequent replacements throughout its entire period.
Precise inclination design and automatic tracking of the support structure. Compared with flat-lying components, it can increase power generation by 10% to 30%.
The support structure has ventilation function, reducing the working temperature of the components and minimizing temperature-related degradation.
Designed according to national standards for load-bearing, resistant to strong winds, snow, and earthquakes. The structural mechanics calculation is qualified.
Modular assembly, reinforced nodes, no on-site welding for on-site assembly, and strong overall rigidity.
All prefabricated modular components are assembled with bolts on-site. No on-site welding is required.
The accessories are universal and compatible with mainstream 550W/700W/700W + large-sized photovoltaic modules. It is compatible with double glass and single glass modules.
Aluminum alloy supports have a light weight, reducing the roof load. Galvanized steel supports have high cost performance and low unit cost.
The profiles are regular, the packaging is compact, and the loss during logistics transportation is small, with lower freight costs.
Ground power stations, color steel tile roofs, concrete roofs, photovoltaic car shelters, fishery photovoltaic integration, and mountainous photovoltaic can all be customized.
It can be adjusted for inclination, arranged in double rows or single rows, and adapted to terrain with height differences.
Steel and aluminum alloy are 100% recyclable, with no construction waste. The zinc-aluminum-magnesium coating has no heavy metal pollution and meets the requirements of zero-carbon photovoltaic projects.
