🚀 Product Innovation & Upgrades: Efficiency and Compatibility Take Center Stage

HQ Mount: 8 mm Aluminum Hook – In November, HQ Mount launched an 8 mm‑thick aluminum hook, significantly thicker than most market alternatives. Its patented “Click Holder” technology allows rapid rail attachment and simplifies rail splicing, aiming to greatly improve installation speed and reliability.

Longsun: High‑Compatibility Hook – Longsun Green Energy introduced a new generation of adjustable solar hooks compatible with clay tiles, asphalt shingles, metal roofs, and more. The hooks have passed wind tunnel tests, withstand wind speeds up to 60 m/s (216 km/h), and adapt to roof pitches from 10° to 60°.

K2 Systems: Ultra‑Thin Hook – K2 Systems released the SingleHook 3S Light, reducing hook thickness to just 6 mm. The slimmer profile makes insertion under tiles easier, reduces installation difficulty, and minimizes on‑site tile handling.

AEROCOMPACT: Fast‑Install Systems & Foldable Hooks – AEROCOMPACT promoted its COMPACTFLAT fast‑install system and foldable roof hooks in 2024. The foldable design greatly simplifies transport and rooftop handling; a single person can carry up to 20 units onto the roof, and the quick‑release clamp streamlines installation.

🏢 Industry Consolidation & Strategic Partnerships: Major Players Reshape the Landscape

Unirac Acquires SolarHooks – North American mounting leader Unirac acquired SolarHooks, a specialist in residential roof hooks. The acquisition expands Unirac‘s residential roof portfolio, reflecting the market’s continued focus on efficient, streamlined hook solutions.

Longsun Green Energy Strategic Partnership – Longsun Green Energy (Xiamen) signed a strategic cooperation with European EPC giant BayWa r.e., further promoting its “SolarRoof Pro 2.0” tile roof PV mounting system in the European market.

Industry Self‑Discipline Pact – In May 2024, the China Photovoltaic Industry Association issued the “PV Mounting Industry Self‑Discipline Pact,” aiming to regulate product quality and technical standards for mounts (including hooks) and promote healthy industry development.

Domestic Companies‘ Technology Development – Jiangsu Nabei Aluminum obtained a patent for an “aluminum alloy solar mount” in December 2024, using a gear linkage mechanism for convenient angle adjustment. Xinwei Aluminum obtained a patent for a “track‑type solar alloy mount” also in December 2024, supporting both height and angle adjustment – demonstrating continued innovation by Chinese companies in aluminum hooks and mounts.

🧠 Patents & Technology Breakthroughs: Intelligence Meets High‑Performance Materials

GoodWe: Photovoltaic Tile Hook System – GoodWe obtained a utility model patent for a “hook and photovoltaic tile system.” The design allows the hook to be displaced relative to the connector under external force during installation, thereby adjusting the overlap distance between adjacent PV tiles, helping to increase effective power generation area and improve efficiency.

S‑5!: 50 New Patents & Extreme‑Weather Certification – As a global leader in metal roof attachment solutions, S‑5! added 50 new patents in 2024, bringing its total portfolio to 194, covering multiple global markets. At the same time, its PVKIT HUR 2.0 rail‑less mounting system obtained FM 4478 certification, capable of withstanding wind uplift up to 150 psf, making it suitable for high‑wind and hurricane zones.

BLUBASE B.V.: Roof Hook Patent Application – Dutch company BLUBASE B.V. filed an international patent application (PCT/NL2024/050494) for a “ROOF HOOK” in September 2024, indicating ongoing innovation in fundamental hook design.

HYPSET: Funding & Technology Breakthrough – HYPSET completed over RMB 100 million in Series A and A+ funding in May 2024, with cumulative orders for its flexible PV mounting system exceeding 3 GW. The system uses a “three‑cable space‑truss structure” and has achieved large‑scale replacement of traditional fixed mounts in complex scenarios such as mountain agrivoltaics and fishery‑solar hybrids.

📈 Market Dynamics & Growth Trends

Balcony Solar & BIPV Drive Demand – With the explosion of the balcony solar market, demand surged for portable hook systems that can be quickly attached to balcony railings. At the same time, BIPV projects are pushing for more aesthetic, low‑profile hook solutions.

From “Universal” to “Specialised” – To accommodate different tile profiles (flat tiles, Roman tiles, corrugated tiles) and installation conditions (e.g., chemical anchors for concrete roofs), the market saw an increasing number of customised hook solutions to meet diverse requirements.

🏗️ Project Application Examples

12.5 kW Rooftop Project in Hungary – A 12.5 kW rooftop PV project in Hungary used the T01 tile roof hook system, specifically designed for ceramic and concrete tile roofs, installing PV panels without damaging the waterproof layer.

1 MW Rooftop Project in Germany – HQ Mount signed a contract with a German customer to supply hooks and other mounting solutions for a 1 MW rooftop PV system.

Field Validation in Greece – HQ Mount‘s new aluminum hooks were demonstrated in a project in Greece; the installation team completed work swiftly thanks to the improved design, validating real‑world efficiency and convenience.

🏛️ Standards & Certifications: Quality Thresholds Continue to Rise

TÜV Certification – In 2024, several manufacturers including HQ Mount announced that their solar hook products had successfully passed TÜV certification. TÜV certification is an internationally recognized mark of safety and quality, crucial for expanding into international markets and reducing risk.

FM 4478 & Hurricane‑Zone Approval – S‑5!‘s hooks and rail‑less mounting systems obtained FM 4478 certification and Florida’s rigorous High‑Velocity Hurricane Zone (HVHZ) approval in 2024, enabling reliable deployment in high‑wind and hurricane zones.

UL 2703 & Steel Section Standards – Industry standards continued to evolve. Companies such as YHeng claimed that their hook systems meet UL 2703 fire safety standards. Meanwhile, the domestic YB/T standard for “Steel sections for PV mounts” was reviewed in 2024, providing technical specifications for hook materials.

🔮 Future Trends Summary

Material Innovation – High‑strength aluminum, Zn‑Al‑Mg coated steel, and other materials will continue to be applied to reduce weight and improve corrosion resistance.

Intelligence & Fast Installation – Tool‑free installation, snap‑fit designs, and similar technologies will become more widespread, further reducing installation labor hours.

Platformisation & Standardisation – Hook designs will become more modular to accommodate a wider range of rail systems and module types.

Expanding Applications – With the rapid growth of BIPV and balcony solar, greater demands are placed on hook aesthetics, portability, and ease of use.
