In 2023, the global newly installed PV capacity exceeded 350GW, with large-scale ground-mounted PV, PV-solar hybrid systems, offshore PV and industrial & commercial distributed projects under full development.

Wire Mesh Trays for Solar Applications have become the mainstream choice for PV cable management systems due to their core advantages of lightweight, easy installation, excellent heat dissipation and high corrosion resistance.

Large-scale Application of Zinc-Aluminum-Magnesium Alloy Wire Mesh Trays

In 2023, enterprises including Yuanhui and Fengtu Cabling launched zinc-aluminum-magnesium wire mesh trays dedicated for solar applications, adopting a dual anti-corrosion process of "hot-dip zinc-aluminum-magnesium + fluorocarbon coating" with automatic cut-edge repair. The outdoor anti-corrosion service life reaches 25 years, reducing costs by 15% and extending service life by 60% compared with traditional hot-dip galvanized cable trays.

Launch of Large-span Lightweight Wire Mesh Trays

In August 2023, Anhui Shangpin New Energy put into operation 15 automated production lines for PV cable trays and launched 6-meter extra-long span wire mesh trays, requiring no intermediate support for a single span. It adapts to complex scenarios such as PV-solar hybrid and mountain PV, reducing bracket usage by 50%.

NEC 2023 Standard Update Boosts Popularization

The 2023 revision of the U.S. National Electrical Code (NEC) Clause 690.31 relaxed the fixing spacing requirements for PV cables in open wire mesh trays (from 4.5 feet to 54 inches), greatly simplifying installation procedures and driving the penetration rate of wire mesh trays in the North American PV market to exceed 60%.

Snake Tray Launches Solar Snake-Loc Wire Mesh Tray System (July 2023)

A leading U.S. cable management manufacturer launched a patented wire mesh tray with snap-on hangers, featuring top cable routing without tools. It allows installation of 500 meters of cables per hour, suitable for 750Kcmil high-current PV DC cables, and has obtained dual UL and TÜV certifications.

Yuanhui Launches Anti-corrosion Wire Mesh Trays for PV Applications (September 2023)

Targeting severe cold and sandstorm regions such as northern Shanxi and Inner Mongolia, it developed wire mesh trays resistant to -30℃ low temperature and UV rays, applied in 50MW PV projects in Shanxi and 30MW in Inner Mongolia, achieving zero corrosion in 3 years and reducing cable loss rate from 3% to 1.2%.

Fengtu Cabling Hot-dip Galvanized Wire Mesh Trays Applied in Suzhou Distributed Project (November 2023)

Provided fully enclosed hot-dip galvanized wire mesh trays for a 546.7kW rooftop PV system in Suzhou, with a zinc coating thickness of 80.7μm (exceeding the national standard of 65μm), adapting to harsh outdoor rooftop environments and ensuring long-term stable operation of cables.

Wire mesh trays for solar applications achieved technological maturity and market validation in 2023 and will enter a full-scale popularization period in 2024.

With the large-scale and diversified development of PV power stations, wire mesh trays will become the standard configuration of PV cable management systems relying on the advantages of lightweight, fast installation, high heat dissipation and strong corrosion resistance. The global market penetration rate is expected to exceed 50% in 2024, driving the overall construction cost of PV power stations to drop by another 15%.
