In 2023, as global photovoltaic installed capacity continued to rise, the roof hook and mounting system industry—the “invisible skeleton” of PV systems—witnessed a critical year of technological innovation and market restructuring. From Europe to North America and the Asia-Pacific region, the industry focused on improving installation efficiency, enhancing load-bearing capacity, and adapting to complex roof structures.

Below are the major news and technology trends in this sector for 2023.

I. Product Technology Innovation: Moving Away from Complexity Toward “Integration” and “High Load-Bearing”

In 2023, roof hooks evolved beyond simple connectors into highly integrated systems combining sealing, height adjustment, and rapid installation.

1. AEROCOMPACT Launches “Universal” Solution

Keywords: sealing innovation, reduced material consumption, time savings

At the end of July 2023, Austrian PV mounting system specialist AEROCOMPACT officially launched its new universal roof hook system, the COMPACTPITCH XM-F REPTILE.

Considered one of the year’s major innovations in the European market, the system addressed two pain points of traditional hook installation: tile cutting and waterproofing. It features a patented labyrinth sealing technology that achieves permanent sealing without additional sealing components, even where tiles are penetrated. More importantly, the design allows installers to transfer forces directly to the rafters independently of the tile structure. Thanks to its high load-bearing capacity, when paired with the new X60 rail, the system extends the spacing between roof hooks to 1.4 meters, significantly reducing the number of hooks required. The company claimed it could reduce installation time by up to 40% while significantly lowering material costs.

2. IBC Solar Upgrades Focus on Detail Improvements

Keywords: detail optimization, quick installation

At the Intersolar Europe exhibition in Munich in June 2023, IBC Solar showcased its updated flat-roof system IBC AeroFix G3 and pitched-roof system IBC TopFix 200.

While the IBC TopFix 200 remained a versatile modular system, the improvements to the AeroFix G3 were particularly representative. The company optimized the tilt joints with a straight-bar design for easier alignment, and replaced conventional screw-and-T-slot nut assemblies with thin-metal-plate screws for wind deflector brackets, significantly boosting installation efficiency. In addition, a new internal butt connector not only enhanced stability but also served as a lightning conductor, simplifying system design.

3. Surge in Demand for Stainless Steel Hooks

Keywords: corrosion resistance, high adaptability

According to market observations at the end of 2023, stainless steel tile roof hooks became a focal point of demand. As PV systems gained popularity in coastal and harsh climate regions, the need for highly durable, corrosion-resistant components increased significantly. Industry analysis noted that stainless steel hooks—valued for their excellent durability, adaptability to various tile types (including S-tiles and flat tiles), and compliance with international industry standards—had become a key component favored by professional installers to ensure long-term return on investment for PV systems.

II. Industry Exhibition Trends: Pre-Applied Adhesives and No-Penetration Technologies Take Center Stage

At the North American Intersolar NA exhibition in February 2023, industry trends pointed toward simpler installation technologies.

Industry observers noted a clear shift toward pre-applied butyl adhesive in pitched-roof mounting solutions. This design allows hooks to be fixed to the roof using adhesion plus a minimal number of screws, reducing penetrations and lowering the risk of leaks.

SnapNrack’s TopSpeed System: A highly anticipated new product at the exhibition. Its distinctive feature is that the hooks are pre‑assembled onto the PV modules before reaching the roof. For the first row, installers only need to apply adhesive and secure it with four half-inch bolts at the designated locations; an extended arm then automatically aligns the next row, greatly simplifying layout work.

SolarPod’s Z-Rack System: Designed for users who prefer not to penetrate the roof, Z-Rack offers a ballasted solution. It clamps onto the roof ridge and remains in place using the weight of the modules and the racking system, requiring no roof penetrations. It has passed wind tunnel tests for wind speeds up to 170 mph.

III. Market Dynamics and Strategic Collaborations: Strong Alliances and Local Innovation

Beyond product innovation, 2023 was also a year of deepened collaborations and accelerated market expansion.

1. SnapNrack and S-5! Announce Strategic Partnership

Keywords: kit integration, simplified supply chain

On August 29, 2023, SnapNrack, a leading U.S. mounting solution manufacturer, and S-5!, a renowned authority in metal roof attachment accessories, announced a joint partnership.

The core of this collaboration was to streamline the installation experience. The two companies pre‑assembled S-5!’s various metal roof mounting attachments (such as the CorruBracket™, SolarFoot™, etc.) with SnapNrack’s Universal L Foot, creating a single kit solution. This meant installers no longer needed to manually assemble two components from different brands on the roof, reducing tedious bolt and nut operations, lowering the risk of losing parts on site, and shortening installation time.

2. Technological Innovation by Local Chinese Enterprises

Keywords: patent strategy, metal roof specialization

In October 2023, Chinese NEEQ-listed company Rixin Technology (835679) was granted a utility model patent for an “installation clamp and installation structure for photovoltaic modules on metal sheet roofs.”

This innovation targets the widespread use of metal sheet roofs in China and the Asia-Pacific region. The clamp features a simple structure, eliminating the need for traditional purlins. It directly clamps onto the middle rib of the metal sheet using a fixing groove formed by a first clamping plate and a second clamping plate. This design not only reduces the system’s weight but also secures frameless PV modules directly via a press plate structure while ensuring adequate ventilation space underneath, enhancing safety. It reflects the deep specialization of local Chinese enterprises in the commercial and industrial distributed PV sector.

IV. Market Data Overview

According to market research, the Asia-Pacific solar PV mounting system market was valued at US$8.6 billion in 2023. While fixed mounting systems still dominated, demand for rooftop-specific mounting systems grew strongly, particularly in China and India. With the proliferation of residential PV, the demand for core components such as roof hooks experienced explosive growth in 2023.
