Clenergy’s Ascent 1.1: Lightly Ballasted Flat Roof System with Enhanced Lightning Protection
Nathalie Kermelk, Product Director at Clenergy, and René, Solution Engineer, present Clenergy's solar mounting solutions at The smarter E Europe 2026. The walkthrough highlights the ground-mount Solar Tracker and the Ascent 1.1 flat roof system, emphasizing their design and market applicability for installers and developers.
Advanced Ground-Mount Tracking Systems for Utility and Agriculture
Nathalie Kermelk, Product Director at Clenergy, details the Clenergy Solar Tracker, which is offered in 1P and 2P configurations to accommodate different module orientations. These trackers can achieve lengths of up to 120 meters and integrate up to four strings, each capable of holding 30 modules. The system operates with a standard tilt of up to 60 degrees. A specialized Agri PV variant extends the tilt angle to 75 degrees, a feature designed to facilitate the passage of large agricultural machinery between module rows. Kermelk highlights the octagonal drive tube as a distinctive design choice, providing increased torsional stability compared to square tubes, which Clenergy states allows for optimized material usage through thinner wall thickness while improving robustness.
"Die meisten Hersteller verwenden hier eher ein Quadratrohr und wir haben uns für ein Achteckantriebsrohr entschieden, weil das eben stabiler ist gegen Torsion." Kermelk · Clenergy · 02:06
Efficient and Secure Flat Roof Mounting with Ascent 1.1
René, Solution Engineer at Clenergy, introduces the Ascent 1.1, a lightly ballasted flat roof system engineered for rapid installation. A primary characteristic is its click-in design, which minimizes the number of components and incorporates pre-assembled module clamps. This approach is intended to streamline the installation process, reducing time and complexity for installers. The Ascent 1.1 system provides 10-degree inclination for East-West configurations and offers both 10 and 15-degree options for South-facing arrays. René emphasizes the system's lightning current carrying capacity (LPS), a critical safety feature for the German market. The system also includes a specific Protection Mat, tailored for compatibility with either EPDM or PVC roof types.
"Was hier das große Merkmal ist, es ist ein Klick-in-System. Es ist nur gesteckt, wenig Komponente, vormontierte Modulklemmen." René · Clenergy · 03:08
Clenergy's Comprehensive Mounting Solutions and Technical Support

Frequently asked questions
What are the primary configurations available for the Clenergy Solar Tracker?
According to Nathalie Kermelk, Product Director, the Clenergy Solar Tracker is available in 1P (one module vertical) and 2P (two modules vertical) variants. A specialized Agri PV tracker is also offered for agricultural applications.
How does the Agri PV Tracker variant support agricultural land use?
The Agri PV Tracker can achieve a tilt angle of up to 75 degrees. This increased tilt allows for the passage of large agricultural machinery between the module rows, enabling combined land use for energy generation and farming.
What is the key engineering advantage of the Solar Tracker's octagonal drive tube?
Nathalie Kermelk explains that the octagonal drive tube provides superior stability against torsional forces compared to standard square tubes. This design choice by Clenergy allows for reduced material thickness while maintaining or enhancing structural integrity.
What features make the Ascent 1.1 flat roof system efficient for installation?
René, Solution Engineer, states that the Ascent 1.1 incorporates a click-in system, uses minimal components, and includes pre-assembled module clamps. This design significantly streamlines the installation process, aiming to save time and labor.
What safety compliance is featured in the Ascent 1.1, particularly for the German market?
René highlights that the Ascent 1.1 is designed with LPS (lightning current carrying capacity). This feature is especially important for the German market, providing enhanced protection against lightning strikes for flat roof PV installations.
Does Clenergy offer support to installers beyond providing products?
Yes, René confirms that Clenergy provides comprehensive support, including product training for its customers. They also offer on-site assistance for initial installations across both flat and pitched roof system projects.
