Driven by the global "dual carbon" goals, the photovoltaic industry is undergoing a new round of technological transformation. As the "skeleton" of photovoltaic power stations, material innovation in support systems has become a focal point for the industry. Carbon fiber composite photovoltaic supports, with their groundbreaking advantages such as lightweight high strength, ultra-long durability, and green low-carbon properties, are now fully surpassing traditional hot-dip galvanized steel supports. These supports have become the core foundation for high-quality development in photovoltaic power stations, propelling the photovoltaic industry into a new era of greater efficiency, longer durability, and enhanced environmental sustainability.

1. Lightweight and high-strength, with comprehensive performance surpassing standards, building the core competitiveness of power stations

 Although traditionally hot-dip galvanized steel supports are widely used, they inherently suffer from drawbacks such as high weight, susceptibility to corrosion, and difficult installation. Carbon fiber composite supports, with carbon fiber as the reinforcing material and high-performance resin as the matrix, achieve a qualitative leap in performance through pultrusion molding.

 Ultra-lightweight, weight reduction exceeding 60%: With a density of only 1.5-1.6g/cm³, approximately 1/5 that of steel and 2/3 that of aluminum alloy. The weight of a single-megawatt support structure is reduced from 73 tons with traditional steel to less than 30 tons, significantly lowering transportation costs and installation difficulty, making it particularly suitable for weak foundation scenarios such as rooftops, mountains, and high-altitude areas.

With a strength exceeding steel by 7 times and a safety factor doubled: the tensile strength reaches up to 3500MPa, which is 7 times that of ordinary steel, and the specific strength (strength/weight) is 5-6 times that of steel. It can withstand wind loads of up to 1.8kN/m², resisting Category 17 super typhoons. Under extreme conditions such as strong winds, blizzards, and earthquakes, the deformation is only 0.5%, far surpassing the structural stability of traditional supports.

Installation efficiency improves by 50%, significantly reducing labor costs: lightweight + modular design eliminates the need for large lifting equipment, allowing single-person easy transportation and installation. The installation efficiency is 50% higher than traditional steel supports, with labor costs per megawatt reduced by over 30%

2、 Super durable, 30 years maintenance free, solving traditional corrosion problems

The design life of photovoltaic power plants is 25-30 years, and the durability of the brackets directly determines the overall life cycle benefits of the power plant. Traditional hot-dip galvanized steel brackets may experience coating peeling, corrosion, and perforation within 5-8 years in salt spray, humidity, acid alkali, and strong ultraviolet environments, requiring frequent maintenance and replacement. The carbon fiber composite material bracket exhibits inherent super weather resistance.

Super corrosion resistance, completely bidding farewell to rust: The material itself is inert and does not react with acid, alkali, or salt. After 5000 hours of salt spray testing, there is no corrosion. In extreme environments such as coastal high salt spray, chemical areas, and saline alkali land, the service life can reach more than 30 years, which is twice the 15 year service life of traditional steel supports.

Anti aging and anti fatigue, zero attenuation performance: high and low temperature resistance (-40 ℃ to 85 ℃), strong UV resistance, performance retention rate of more than 85% after 2000 hours of UV aging test; After 10 cycles of alternating load testing, the strength retention rate reached 90%, with no risk of metal fatigue, and the structural performance remained stable after long-term use.

Zero maintenance cost, more economical throughout the entire lifecycle: no need for anti-corrosion coating, no need for rust removal and maintenance, maintenance cycle extended to 5-8 years, reducing the maintenance cost of a single power station's entire lifecycle by more than 80%, solving the pain point of traditional brackets' "annual repair, ten-year replacement".

3、 Green and low-carbon, energy-saving and emission reduction, helping photovoltaic achieve a "zero carbon" closed-loop

As a carrier of clean energy, the greening of the photovoltaic industry itself is crucial. Carbon fiber composite material brackets, from production, use to recycling, practice low-carbon concepts throughout their entire life cycle, becoming a key link in achieving the goal of "zero carbon" in photovoltaics.

Low carbonization production reduces energy consumption by 40%: The energy consumption of pultrusion molding process is reduced by 40% -60% compared to steel galvanizing and aluminum alloy extrusion. There are no high pollution processes such as acid washing and galvanizing, and the production process has no wastewater or exhaust gas emissions.

Transportation and installation emissions reduction, reducing the carbon footprint of the entire lifecycle by 50%: lightweighting reduces transportation energy consumption by 60% and carbon emissions by 50%; The carbon footprint of the entire lifecycle is reduced by 35% -50% compared to traditional steel supports, and a single megawatt power station can reduce carbon emissions by over 100 tons.

Recyclable and recyclable, building a green closed-loop: Retired brackets can be broken, separated, reshaped, and regenerated. The carbon fiber recovery rate is over 95%, and the performance loss after regeneration is less than 5%, achieving a "production use recycling reproduction" green cycle and meeting the requirements of circular economy development.

4、 Empowered by technology, adaptable to all scenarios, leading to high-quality development of photovoltaics

Carbon fiber composite material brackets, with their strong designability, good insulation, and wide adaptability, break through the limitations of traditional bracket scenarios and provide new possibilities for diversified layout of photovoltaic power plants.

Insulation safety, eliminating the risk of electrical leakage: The material itself is insulated, without the risk of conductive corrosion, avoiding the hidden dangers of electrical leakage and lightning strikes in traditional metal brackets, and improving the operational safety of the power station.

Adapting to complex terrains and expanding application boundaries: Flexible and modular design, suitable for complex scenarios such as mountains, hills, water surfaces, roofs, etc., helping photovoltaics expand to resource rich areas such as deep seas, deserts, and high altitudes.

Technological iteration accelerates and costs continue to decline: With the mass production and process optimization of domestic carbon fiber, costs have decreased by 40% compared to 5 years ago, and cost-effectiveness continues to improve. It is now fully popularized from high-end scenarios to centralized and distributed power stations.

Conclusion

From 'usable' to 'easy to use', from 'traditional' to 'green', carbon fiber composite photovoltaic brackets have completely overturned the traditional bracket system with their three core advantages of performance, durability, and environmental protection. It is not only the "skeleton" upgrade of photovoltaic power plants, but also an important symbol of high-quality development and green low-carbon transformation of the photovoltaic industry.

With the maturity of technology and cost reduction, carbon fiber composite material scaffolds are rapidly becoming the mainstream choice in the industry. Choosing it means choosing a safer, more durable, more economical, and more environmentally friendly photovoltaic future, injecting strong momentum into the global energy transition, and helping to achieve the "dual carbon" goal as soon as possible.
