Introduction
In 2023, the global solar mounting rail industry achieved breakthroughs in both technology and market demand. Lightweight, rail-free and highly adaptable products were launched intensively, driving continuous reduction in PV system BOS costs.
1. Market Scale: Surge in Global Demand in 2023, Chinese Enterprises Leading the World
In 2023, global shipments of PV tracking brackets reached 92GW, a year-on-year increase of 28%. As a core supporting component, solar mounting rail witnessed synchronous expansion in market size. According to Wood Mackenzie, Chinese enterprise CITIC Bo ranked among the world's top 5 tracking bracket manufacturers with a 9% market share, becoming the only Chinese company in the top five. Its supporting rail products were exported to Europe, America, Latin America and other core markets along with tracking systems. Trina Solar shipped 9.6GW of bracket products in 2023, with rail products adapted to 700W+ high-power modules, helping reduce BOS costs.
In the domestic market, the boom of distributed PV has driven demand for rooftop solar mounting rails. Aluminum alloy rails occupy more than 80% of the market due to their advantages of light weight and corrosion resistance.
2. Technological Innovation: Three Breakthroughs in Solar Mounting Rail in 2023
Rail-Free & Short-Rail Technology: Subverting Traditional Installation
In August 2023, Pegasus launched the SkipRail rail-free system, which can directly eliminate multiple rows of rails and use the strength of modules for load-bearing. It adapts to 160mph wind speed and 40psf snow load, reducing 2 miles of rail usage and 10,000 pounds of material transportation cost per project. Chinese enterprise Sunforson mass-produced the SFS-SR-13 short rail in November, suitable for trapezoidal metal roofs and installable vertically along corrugations, solving the installation direction limitation of traditional rails.
Lightweight & High Strength: Upgraded Aluminum Alloy Materials
Mounting Solar launched AL6005-T5 aluminum alloy double-layer rails with anti-corrosion service life exceeding 30 years after anodizing. The high-fit double-layer structure adapts to irregular roofs and improves installation efficiency by 40%. AEROCOMPACT released the COMPACT PITCH X60 rail with 30% higher strength, reducing roof hook usage by 30% and cutting installation costs and time.
Scenario Adaptation: Covering Special Installation Environments
K2 Systems and Solarmotion completed a 325kW vertical PV project in Switzerland, adopting K2 BasicRail rails adapted to 75° retaining walls and fixed with HUS anchors to meet the maximum 90mm anchoring depth requirement, solving structural and anti-corrosion challenges in vertical installation. AEROCOMPACT launched the COMPACTFLAT SN2 rail system, compatible with large modules up to 2348mm×1303mm, supporting both east-west and south-facing configurations for various flat roofs.
3. Industry Trends: Development Directions of Solar Mounting Rail in 2023
- Cost reduction and efficiency improvement as the core: Rail enterprises promote a 15%-25% drop in BOS costs through modular design, fewer accessories and simplified installation, matching grid parity demand.
- Adaptation to high-power modules: The popularity of 700W+ modules forces rail upgrades. Large-span, high-load-bearing rails become standard, reducing usage while enhancing system stability.
- Accelerated domestic substitution: Technological breakthroughs by Chinese enterprises such as CITIC Bo and Kingsolar lifted the global market share of domestic solar mounting rails to over 35% in 2023.
- Policy-driven standardization: The implementation of the new national standard Technical Requirements for Photovoltaic Power Station Brackets added anti-seismic and anti-fatelligence specifications, promoting quality upgrading and third-party certification for rail products.
