As the global energy transition accelerates, photovoltaic mounting systems—the "skeleton" of solar power plants—are seeing their technological innovation and market adaptability become focal points of industry competition. Since the beginning of 2026, from Japan’s PV EXPO to Italy’s KEY Energy Show and the World Future Energy Summit (WFES) in the Middle East, a wave of rooftop-specific mounting solutions has emerged at major global PV exhibitions. Companies are no longer simply providing basic metal structures; instead, they are shifting toward systematic, intelligent, and scenario-based total solutions. In particular, addressing pain points in rooftop installation—waterproofing, wind resistance, load capacity, and installation efficiency—has led to multiple breakthrough products.

I. Global Exhibition Roundup: Rooftop Mounting Solutions Take Center Stage

1. Japan PV EXPO 2026: Focus on Complex Terrain and Waterproofing Technology

At the PV EXPO Spring Show in Japan held in March, Mibet showcased a comprehensive solution tailored to Japan’s mountainous terrain and typhoon-prone climate. For commercial, industrial, and residential rooftops, Mibet introduced its flat roof matrix system and color steel tile clamps, emphasizing the combination of a lightweight structure with leak prevention. By reducing roof load while ensuring sealing integrity, the system directly addresses Japan’s stringent building safety and waterproofing requirements. Additionally, its exhibited dual-column waterproof solar carport integrates structural waterproofing with EPDM gasket design, merging carports with photovoltaic power generation to meet practical needs in commercial and industrial settings.

2. European Shows (KEY & SOLAR SOLUTIONS): Digitalization and Full-Scenario Coverage

Europe remains a key battlefield for rooftop distributed photovoltaics. At KEY 2026 in Italy and SOLAR SOLUTIONS in the Netherlands in early March, Antai New Energy showcased its ALTRA-ROOF series of rooftop mounting systems. The series covers diverse scenarios including tiled roofs, flat roofs, metal roofs, and balcony installations, emphasizing quick installation and structural strength. Beyond hardware, Antai also demonstrated the SolarAid rooftop PV design platform at the Dutch show, leveraging digital tools to improve efficiency in site survey and design stages—marking a shift from selling products to delivering integrated solutions.

Notably, demand for architectural aesthetics is growing in the European market. Concurrently at KEY, multiple module manufacturers launched all-black back-contact (BC) modules to achieve seamless building integration. This trend is pushing mounting systems to evolve toward greater concealment and aesthetics to meet the needs of high-end residential buildings and historically protected structures.

II. Addressing Industry Pain Points: Breakthroughs in Patents and Innovative Products

1. The End of Roof Penetration: Non-Invasive Rooftop Mounting Technology

Traditional rooftop PV installations often require drilling holes in the roof, which can easily lead to leakage risks and structural damage. At the International Roofing Expo (IRE) in the US in January, the Hidden-Fastener Solar Mount (HFSM) exhibited by Martin Roofing & Solar received an award from the U.S. Department of Energy. This technology requires no drilling into tiles; instead, it anchors into traditional nailed plank areas beneath overlapping tiles, achieving true PV-roof integration. Meanwhile, its companion dual-channel service rail (DCSR) integrates cable management, eliminating contact between cables and the roof surface and significantly enhancing system durability and safety.

2. Growing Patent Portfolios from Chinese Companies

Chinese companies are also accelerating technological innovation. In February 2026, Juneng Electric announced that it had been granted a national invention patent: “A Photovoltaic Panel Mounting Bracket and Method for Roof Distributed Systems.” The patent addresses the pain points of complex installation and difficult tilt angle adjustment in traditional brackets, aiming to improve power generation efficiency and reduce operation and maintenance costs. In January, Xujie Technology filed a patent for a “Load-Bearing Positioning Device for Photovoltaic Brackets with Adaptive Load Distribution,” which uses pressure sensors to automatically adjust the center of gravity of PV panels, ensuring uniform force distribution and solving the problem of structural stress concentration under strong wind or snow loads.

III. Market Landscape Evolution: M&A and Localized Services Reshape Competitiveness

1. Accelerated Consolidation in North America

In January 2026, U.S.-based PV mounting manufacturer Pegasus announced the acquisition of Aerocompact’s North American operations. This acquisition marks a further consolidation in the North American commercial and industrial rooftop mounting market. Pegasus will leverage its distribution network of over 130 locations across the United States and Canada to rapidly promote Aerocompact’s flat roof and ground-mount systems. The integration goes beyond product portfolios, aiming to strengthen digital software platform (Glide) capabilities in project design, planning, and procurement.

2. Deep Localization as a Key Competitive Edge

Leading companies are adopting deep localization strategies encompassing R&D, warehousing, and service to address region-specific conditions. Antai New Energy has established a logistics center and local business team in the Netherlands to ensure rapid response in the Central and Northern European markets. In the Middle East, to address high temperatures and sandstorm conditions in desert regions, Antai launched the AT-Spark intelligent tracking system, certified for C5 corrosion protection and wind resistance up to 70 m/s, and set up a local office in Dubai to provide localized technical support.

IV. Future Outlook: Intelligence and Extreme Environment Adaptability

As global climate patterns evolve, the ability of PV mounting systems to withstand extreme weather is becoming an essential requirement. Whether it is typhoon-resistant design in Japan or sandstorm-resistant strategies in the Middle East, it is clear that mounting systems are evolving from passive support structures to active protective components.

Looking ahead, three major trends will shape the development of rooftop PV mounting systems: intelligence, such as incorporating algorithms to automatically adjust tilt angles for wind protection during severe weather; building-integrated materials, where mounting systems become deeply integrated with roofing materials as an inseparable part of the building envelope; and full lifecycle services, shifting from hardware supply alone to comprehensive energy services that include design software, rapid delivery, and operation and maintenance support.
