1. New Product Launches: Faster, Stronger, Smarter

1.1 AEROCOMPACT COMPACTPITCH XT‑R: Foldable Design with Quick‑Release Clamp

In April 2024, Austrian PV mounting expert AEROCOMPACT launched the COMPACTPITCH XT‑R roof hook, a significant addition to its COMPACTPITCH series for pitched roof applications. The XT‑R will make its first public appearance at Intersolar Europe 2024 in Munich.

Key features include:

Integrated quick-release clamp: Allows installers to simultaneously adjust the hook height to the roof batten and fix the hook in place, dramatically reducing installation time.

Foldable design: One person can easily carry up to 20 units onto the roof, minimizing transport and storage costs.

Fine‑toothing mechanism: Rail leveling is simplified — height can be easily adjusted by pushing or pulling on the rail.

Three‑level base plate: Ensures extremely stable attachment and allows height adjustment to match roof battens.

Compatibility: Suitable for rail‑based mounting systems with framed PV modules of any length and width, with frame heights of 30 to 46 mm (or 30 to 50 mm in some specifications).

The XT‑R can be combined with spacer plates, base plate bridges, and AEROCOMPACT‘s metal replacement tiles, and is fully supported by the AEROTOOL planning software. Albert Vonbun, AEROCOMPACT‘s Head of Global Product Management, stated: “With our new roof hook, we are speeding up and simplifying installation and minimizing warehousing.”

For regions with high snow loads, AEROCOMPACT also launched the unbreakable COMPACTPITCH XM‑B metal replacement tile, which can replace concrete or clay tiles and has been certified watertight by an external test laboratory.

1.2 K2 Systems SingleHook FlatTile: Optimized for Plain Tiles

In March 2024, K2 Systems introduced the SingleHook FlatTile (product no. 2004416), specifically designed for plain tile roofs. Plain tiles, the oldest type of clay roof covering, present unique installation challenges due to their overlapping design and higher material consumption. K2‘s new hook addresses these challenges head-on.

Key features:

Side‑mount attachment: The hook can be conveniently attached from the side, dramatically speeding up installation.

Slotted hole for height adjustment: Allows easy rail height adjustment, providing flexibility during installation.

Statically optimized design: Requires fewer roof hooks per design, reducing material costs, and can be verified in more regions.

Integrated waterproofing: The tile under the roof hook is replaced by two metal cover plates (available in red and anthracite) with a butyl strip on the bottom side, ensuring water tightness.

The SingleHook FlatTile replaces the previous plain tile roof hook (product no. 2003073 SolidHook FLA 75×4) and is already available for planning in K2 Base under the SingleRail system.

1.3 Clenergy SolarRoof Pro 2.0: Adjustable Tile Hook for Residential Pitched Roofs

At Intersolar Europe 2024, Clenergy showcased its SolarRoof Pro 2.0 roof‑mounting solution, featuring an adjustable tile hook designed for most residential pitched roofs.

Key features:

Three‑position adjustment range: Offers a wide range of adjustments for different tile thicknesses, wooden structures, or building structure tolerances.

Single‑tool installation: Only one tool is required for the entire system, speeding up on‑site installation.

Flexible layout: Same kit and components work for both landscape and portrait layouts, avoiding the need for two layers of rail and making layout on irregular roofs more flexible.

Safety assurance: High-strength hooks and rails, along with ETA-certified screws, ensure safety even on windy or snowy days, preventing tile fracturing or mounting system failures.

The SolarRoof Pro 2.0 is part of Clenergy‘s “Harmony with Nature”‑themed booth, reflecting the company’s commitment to sustainability and carbon neutrality.

1.4 HQ Mount: 8mm Aluminum Hook with Patented Click Holder

In November 2024, HQ Mount unveiled its latest innovation: a high-strength aluminum hook featuring an 8mm-thick arm — significantly thicker than most market alternatives. This thicker arm enables a wider span between hooks, reducing installation time and material costs.

Key features:

Patented click holder set: Allows for rapid attachment of rails to hooks and simplifies rail splicing with minimal screw fastening, streamlining the entire installation process.

Demonstrated in Greece: A recent project in Greece showcased the new system’s advantages, with the installation team completing their work swiftly thanks to the hook’s improved design.

Industry promise: An HQ Mount representative stated: “Our goal was to make installations faster, safer, and more robust, and we believe this new hook achieves all three.”

1.5 S:FLEX: Hook‑in Roof Hook for Intersolar 2024

S:FLEX presented its new INmount in‑roof system at Intersolar 2024, featuring a hook‑in roof hook made entirely of aluminum. The hook can be flexibly adjusted to the thickness of roof battens and tiles from 49.7 mm to 59 mm, with careful attention paid to an installation‑friendly screw connection on the suspension bracket.

1.6 IBC Solar: New Roof Hooks for TopFix 200 System

At Intersolar Europe 2024, IBC Solar unveiled various new roof hooks for its TopFix 200 system. These hooks are suitable for thicker roof battens, and one model requires only one tool to install the module support profiles, further simplifying the installation process.

2. Installation Technology: Speed and Flexibility

2.1 Tritec Tri‑Stand Series: Lateral and Height Adjustability

The manufacturer Tritec has developed the Tri‑Stand series of roof hooks specifically for connecting solar systems to tiled roofs. The series includes two slightly different hooks:

Tri‑Stand Basic: Laterally adjustable, pushed onto a base plate attached to the rafter. The base plate features twelve holes for centering on rafters, and the bracket slides into a channel across the entire base plate width, allowing precise positioning under the corrugated valley of the roof tile. The upper end of the bracket features a diagonal slot for additional rail adjustment flexibility.

Tri‑Stand Plus: Similar basic design but with a split bracket design. Both parts are screwed together in slotted holes, providing the additional option of height adjustment to compensate for roof unevenness.

2.2 IBC Solar: Snap‑In Roof Hooks

IBC Solar showcased new roof hooks at Intersolar Europe 2024 that fix support profiles by snapping them into place instead of screwing them on, enabling significantly faster installation at end‑customer premises.

2.3 DEKS SolarDek Range: Purpose‑Made Flashings for Watertight Seals

The Solardek range from DEKS includes purpose‑made Solar PV and Thermal Flashings, ensuring watertight seals for cable and pipe penetrations. For flat tile roofs, the SolarDek HookFlash provides weatherproofing for solar panel hooks, while the TileFlash offers a dual‑purpose solution for cables and hooks.
