Rail‑Less Solar Mounting Clamps: Industry News Roundup
2023-04-22
1. Pegasus Solar Launches SkipRail Clamp: Redefining Pitched Roof Solar Installation
Pegasus Solar officially launched its patented SkipRail clamp, a game‑changing rail‑less mounting solution designed to slash installation time, materials, and roof penetrations for pitched roof solar projects.
Key Highlights
- Eliminates Rail Dependency: Removes up to 2 miles of rails, 1,500 roof penetrations, and 10,000 pounds of material per typical installation.
- Extreme Load Ratings: Certified for 160‑mph winds and 40 psf snow loads, suitable for composition shingle, tile, metal, and low‑slope roofs.
- Universal Compatibility: Works with both portrait and landscape panel layouts, and integrates with Pegasus’s existing rail systems for flexible deployment.
- Nationwide Availability: Distributed across the U.S. via solar distributors, with a dedicated design tool for array configuration.
Industry Impact
“SkipRail delivers transformational productivity gains,” said Pegasus CEO Kai Stephan. “It eliminates the risk and labor of drilling and sealing penetrations while cutting material costs dramatically.” The solution leverages the inherent structural strength of PV modules, enabling installers to skip every other rail row in most U.S. regions.
2. S‑5! Introduces S‑5‑RC™ Clamp: Zero‑Penetration Rail‑Less Mounting for Riverclack® Metal Roofs
Leading metal roof attachment specialist S‑5! unveiled the S‑5‑RC™ clamp, engineered exclusively for Riverclack® metal roof profiles, enabling seamless rail‑less solar mounting via its PVKIT® direct‑fix solution.
Key Features
- Mechanical Interlock Design: Two‑piece construction creates a robust, corrosion‑resistant bond with roof ribs, preserving thermal cycling properties.
- Zero Penetrations: No drilling required, protecting roof integrity and warranties.
- Lifetime Warranty: Crafted from high‑tensile structural aluminum, matching the roof’s service life with zero maintenance.
- Flexible Placement: Installable anywhere along the seam, ideal for industrial, commercial, and institutional projects.
Market Expansion
S‑5! expanded its rail‑less footprint by partnering with Total Safety Solutions (TSS) as its authorized distributor for the MENA region, targeting 2.5 million+ metal roofs with solar potential.
3. MVV Energie Files Patent for Rail‑Less PV Mounting System (December 2023)
German energy giant MVV Energie filed a U.S. patent (Publication No. US20230275539A1) for an innovative rail‑less roof mounting system, aiming to secure PV modules via direct clamp assemblies without traditional rails.
Technical Breakthrough
- Dual Clamp Assembly: Each PV module frame is supported by two clamp sets mounted to roof base sliders, ensuring uniform load distribution.
- Adjustable Slider Mechanism: Block and top sliders enable precise alignment and adaptability to varying roof contours.
- Patent Focus: Prioritizes secure, efficient attachment while reducing material usage and installation complexity.
4. Chinese Innovators Advance Rail‑Less Clamp Technology (2023 Domestic Highlights)
4.1 Canadian Solar (CSI) Grants Utility Patent for PV Mounting Clamps (November 2023)
Canadian Solar secured a Chinese utility patent (CN202320517144.9) for an adjustable PV mounting clamp featuring a rotating clamp arm and multi‑position limiter, enhancing stability and installation efficiency across diverse panel sizes.
4.2 Integrated Rail‑Less Point‑Pressure Clamps (August 2023)
Jiangsu‑based manufacturers launched an all‑in‑one rail‑less point‑pressure clamp (Patent CN219535993U) with a T‑slot base and spring‑loaded clamping plate, enabling direct, tool‑friendly panel fixation without rails.
4.3 BIPV‑Optimized Rail‑Less Fixtures
New rail‑less clamps tailored for BIPV systems emerged, offering black finishing for aesthetic integration, improved heat dissipation, and >¥0.1/W cost savings vs. railed setups, with broad compatibility for trapezoidal metal roofs.
