Elevating Rooftop Solar with Clenergy’s Ascent 1.1 System

As solar adoption accelerates globally, rooftop PV installations demand smarter, faster, and more resilient mounting systems. Clenergy’s newly launched Ascent 1.1 answers this call with engineered enhancements that optimize performance, simplify installation, and adapt to diverse markets.

Why Rooftop Mounting Matters Flat rooftop solar installations present unique structural and environmental challenges. Ascent 1.1 addresses these by offering:

  • Aerodynamically optimized design that reduces ballast weight while improving wind resistance.
  • Compatibility with varied roof types including PVC, foil, bitumen, and concrete, ensuring installation flexibility.
  • Simplified logistics with fewer SKUs and preassembled clamps, cutting warehouse and labor costs.

Proven Reliability Across Global Projects From Lithuania to South Africa, the Ascent series has been field-tested in projects ranging from 20 kW to 2.7 MW. Key benefits include:

  • Fast, tool-free installation with patented click-in rail technology.
  • Long-term durability backed by a 25-year warranty.
  • Real-world performance validated by installations on municipal and industrial rooftops across Europe and the U.S.

Design Innovations for Modern Demands The Ascent 1.1 has undergone extensive R&D and wind tunnel testing by the IFI Institute. Innovations include:

  • Improved vent gap ratios and module cantilever balance for better wind resistance.
  • Options for east-west and north-south orientation with elevation angles of 10° and 15°.
  • Dual ballast placement—on base or ballast rails—expanding block size compatibility.

Flexible, Future-Ready Solutions Recognizing that no two markets are the same, Clenergy emphasizes a modular approach:

  • Accommodations for long-side and short-side clamping.
  • Ongoing development of integrated mechanical fixings and green roof compatibility.
  • Customizable protection pads for optimal friction and roof preservation.

By integrating global customer feedback and rigorous testing, Clenergy’s Ascent 1.1 system sets a new benchmark for rooftop solar mounting—delivering innovation, versatility, and performance in one streamlined package.
