International Exhibitions: Chinese Solutions Shine in Europe and Japan

In early March, at the SOLARSOLUTIONS 2026 exhibition in Amsterdam, Antai New Energy showcased its comprehensive PV mounting system solutions. The company’s ALTRA-ROOF series, designed for metal and tile roofs, drew considerable attention. Featuring fast installation and high structural strength, the series precisely meets the rapidly growing demand for commercial, industrial, and residential distributed PV in Europe.

Around the same time, at PV EXPO 2026 Spring in Tokyo, Mibet unveiled its latest metal roof clamps. The products combine high adaptability with lightweight construction, reducing roof load while preventing water infiltration—making them an excellent choice for commercial, industrial, and residential rooftop projects.

Technological Breakthroughs: Rail‑less Designs and Integrated Solutions Take Center Stage

Industry leaders are introducing disruptive solutions. In mid‑February, Mibet launched its Universal Standing Seam Clamp Kit, a rail‑less system that integrates mechanical fastening with electrical grounding. Manufactured from SUS304 stainless steel and AL6005‑T5 aluminum alloy with a coating, the product offers excellent mechanical strength and corrosion resistance. It supports tilt angles from 0° to 15°, can withstand wind speeds up to 60 m/s and snow loads up to 1.6 kN/m², and is designed for a 25‑year service life with a 10‑year warranty.

In early March, LONGi officially launched its LONGi Hi ROOF E metal roof PV solution in Jinan, directly addressing long‑standing industry challenges. The most significant innovation is the complete elimination of rails. Through an interlocking structure between modules combined with high‑strength steel frames, the PV system becomes an integral part of the building rather than an “external add‑on.”

The LONGi solution requires only four types of integrated clamps to cover 80% of metal roof types on the market, including trapezoidal and standing seam roofs. Even more noteworthy is the kit‑based delivery model: all components—modules, clamps, and accessories—arrive at the site as a complete system package, increasing installation speed by 25%. The solution also introduces the industry’s first 15‑year full‑system warranty on materials and workmanship, far exceeding the typical 2‑5 year warranty for connectors.

Material Innovation: Super Weather‑Resistant Steel Validated, Driving Green Transformation

Significant progress has also been made in mounting materials. A pilot project in Yunnan Province using Baoshan Iron & Steel’s super weather‑resistant steel for PV mounts reached a key validation milestone. Three years after grid connection, field inspections showed that the super weather‑resistant steel brackets had developed a uniform, dense brown‑black stable rust layer. The average corrosion rate over the three years met expectations, confirming the material’s suitability for 25‑year PV service life.

This validation demonstrates the advantages of super weather‑resistant steel brackets: no coating required, low environmental impact, and lower total lifecycle costs. The results provide strong support for replacing traditional hot‑dip galvanized and zinc‑aluminum‑magnesium coated steel, and lay a solid foundation for deploying this technology in other climate regions across the country.

Benchmark Project: JD.com “Asia No.1” 13.3 MW Facility Showcases Penetration‑Free Installation

In mid‑March, Antai New Energy disclosed details of the 13.30 MW distributed PV project at JD.com’s “Asia No.1” logistics park in Ruian, Wenzhou. Located in a coastal area, the project had to meet wind and snow load design requirements of 0.45 kN/m². Additionally, the logistics park operates 24/7, severely limiting the installation time window.

Antai’s custom metal roof mounting solution used 60mm dedicated seam clamps securely attached to the standing seam, achieving a penetration‑free installation that preserves roof integrity and waterproofing. The primary load‑bearing structure consisted of high‑strength H‑shaped aluminum rails with a wall thickness of 1.2 mm. The modular “clamp + rail + module clamp” design greatly simplified on‑site installation and allowed multiple work crews to operate simultaneously in different areas.

The project is expected to generate more than 24 million kWh annually, reducing CO₂ emissions by over 20,000 tonnes per year. It represents a successful “PV + smart logistics” model and provides a replicable example for large‑scale logistics parks considering distributed PV.

Global Expansion: Chinese Mounting Companies Accelerate Overseas Presence

Chinese PV mounting companies are rapidly expanding their global footprint. Antai New Energy has established a logistics center and local business team in the Netherlands, along with a global R&D center in Madrid, Spain. Through localized technical teams, the company offers full‑cycle services—from project design to operation and maintenance—for European customers.

Meanwhile, Xiamen Kseng New Energy completed a commercial rooftop project in El Salvador using adjustable‑angle aluminum alloy mounting systems. The system uses adjustable tilt brackets to achieve precise angles of 10‑30 degrees, maximizing solar capture efficiency at the local latitude. Made from 6005‑T5 aluminum alloy, the system offers excellent corrosion resistance, capable of withstanding the harsh conditions of a tropical coastal environment.
