Supply Chain Tensions and Price Fluctuations
2023-10-26
In the first half of 2023, the global solar clamp market experienced significant supply chain pressures due to rising raw material costs (especially aluminum and stainless steel) and logistics disruptions. Multiple manufacturers issued price adjustment notices, pushing up the procurement costs for downstream PV mounting systems. Industry insiders noted that although overall PV installation demand continued to grow, the uneven supply of clamps led to delivery delays for some projects.
Patent Infringement Disputes Intensify
In mid-2023, a well-known European solar mounting system company filed patent infringement lawsuits in several countries against certain Chinese manufacturers, targeting the structural design of specific quick-installation clamps. This event triggered widespread attention in the industry, with multiple exhibitors at the Shanghai SNEC exhibition adjusting their product displays to avoid legal risks. The incident also prompted domestic manufacturers to accelerate their independent R&D and intellectual property layout.
Quality Safety Issues Come to Light
In the third quarter of 2023, a quality inspection agency in a certain country published a test report showing that some low-cost aluminum alloy clamps had insufficient anti-aging properties and resistance to loosening under extreme weather conditions. Several PV plants subsequently conducted batch inspections, and some developers announced that they would blacklist certain suppliers. The incident reignited discussions in the market about balancing low prices with long-term reliability.
Introduction of New Industry Standards
In response to uneven product quality, a national PV industry association released updated technical specifications for mounting system accessories in 2023, explicitly tightening the torque requirements for clamps and the salt spray test duration. Many large-scale procurement tenders began to include compliance with the new standards as a prerequisite for bidding, accelerating the phase-out of non-compliant capacity.
Recycling and Circular Economy Become a Hot Topic
As the first batch of large-scale PV plants entered the module replacement phase, the recycling of mounting systems, including clamps, drew increasing attention. Several companies launched a “recycling + replacement” service model, using recycled aluminum to produce new clamps. This was covered by industry media as a key case in the green circular economy.
