In 2024, the global solar photovoltaic (PV) industry continues to develop at a rapid pace amid the energy transition wave. As the core support of PV power plants, the ground-mounting system has seen multi-dimensional advancements this year in material upgrades, structural optimization, and intelligent integration. Xiamen Topfence Co., Ltd., leveraging its deep technical expertise and global footprint, has emerged as a key driver of innovation in this sector.

This robust growth provides a broad stage for leading companies.

Topfence: A Leader in One-Stop PV Mounting Solutions

Xiamen Topfence Co., Ltd. is a national high-tech enterprise based in Xiamen, China, specializing in the development, design, construction, and operation of solar PV projects. The company operates a GMP-standard factory covering 20,000 square meters, with around 300 employees and an annual production capacity of 300 MW. As of 2024, the company holds 20 utility model patents, and its core products have obtained multiple international quality certifications including UL, TUV, CE, and MCS.

Topfence offers a full range of systems covering ground-mounting, roof systems, solar carports, agrivoltaic systems, and more. The products are widely compatible with core materials such as aluminum and stainless steel, and provide premium anti-corrosion solutions including hot-dip galvanizing and zinc-aluminum-magnesium (ZAM) coatings. Its flagship steel ground-mounting system uses high-yield-strength Q235B/Q355B steel, capable of withstanding wind speeds up to 216 km/h and snow loads as high as 3.6 kN/m², ensuring stable operation of power plants for over 25 years even in extreme conditions.

Innovation-Driven: Material Upgrades and Technological Barriers

In 2024, Topfence continued to break new ground in product innovation. To address the challenges of high-corrosion, high-insolation environments in the Middle East and Southeast Asia, the company launched a full series of Zinc-Aluminum-Magnesium (ZAM) coated solar mounting systems. With a coating thickness of ≥275 g/m², these systems can withstand over 3,000 hours in salt spray tests without red rust, and the cut edge features a unique “self-healing” capability, completely solving the corrosion maintenance problems of traditional hot-dip galvanized systems. The entire system uses Q355 high-strength steel, reducing material usage by 15% compared to conventional solutions, achieving both lightweight design and structural strength.

In the direction of smart integration, Topfence deeply incorporates AI, the Internet of Things (IoT), and energy storage systems into its PV mounting solutions, taking the lead in launching products such as PV tracking systems and floating PV mounts. In December 2024, the company was granted a utility model patent for a “Photovoltaic bracket with adjustable angle” . Through a precision adjustment telescopic part and multi-angle adjustment assembly, this design enables flexible tilt angle adjustment of PV panels, significantly improving power generation efficiency at different latitudes.

Landmark Project: Agrivoltaic Power Plant in South Gyeongsang Province, South Korea

In 2024, Topfence successfully delivered the ground-mounting system for a large-scale agrivoltaic solar power plant in South Gyeongsang Province, South Korea. The project used ZAM-coated steel with high corrosion resistance, adapted to local soil and terrain conditions. The modular bracket design enabled rapid assembly and installation, simplifying construction processes while ensuring structural strength and stability.

The power plant directly employed ground screw foundations, minimizing disturbance to agricultural soil and reflecting an environmentally friendly construction concept. The project also adopted large-span design and adjustable tilt brackets, which ensures sufficient sunlight and growing space for crops while optimizing solar irradiation angles to boost overall power generation revenue. This successful model explores a win-win path for clean electricity and agricultural production.

Honors and Certifications

In 2024, Topfence was recognized as a “National High-Tech Enterprise” and received the “Caring Enterprise” title for its high product quality and innovation. The company has established long-term, stable strategic partnerships with several Fortune Global 500 companies, further solidifying its industry-leading position.
