Getting Started with clawFRplus
Transforming the way Flat Roof is Done.
clawFRplus is recommended for all new flat roof projects. Built upon the foundation of clawFR, the system incorporates enhancements to boost compatibility with large format solar modules. Its high-side and low-side clamps simplify installation and maintenance while supporting higher wind and snow loads. clawFRplus boasts faster build speed by virtue of fewer parts when mounting some module types. The system offers the same design options and intelligent O&M features, along with the reliability you have come to expect from PanelClaw.
Technical Details
Reliability
clawFRplus is the most rigorously tested flat roof racking system in the world, featuring Class A fire ratings, module-level mechanical load listings, and high-strength structural steel components, all backed by a 25-year limited product warranty.
- Full DNV-GL technical and operational bankability report
- Most rigorously tested flat roof racking platform in the world
- ASCE 7-16/22 and SEAOC PV1 and PV2 2017 full compliance with peer review
- ANSI/UL 2703-2015 Listing
- Class A fire rating for Type I and Type II modules with no additional parts required
- Module specific load ratings for upward and downward loads
- Electrical grounding and bonding using a single lug per subarray
- High strength structural steel components
Faster Build Speed:
clawFRplus has a single-bolt hardware kit and features tool-less module attachment for fast, reliable assembly.
- Single bolt hardware kit with no loose nuts
- Tool-less patent pending module attachment means speed
- Flexible order of operations: build your racking before modules arrive or hang modules as you build. Let site conditions and project conditions dictate optimal order of operations, not the racking.
- Simplified wire management
- Pre-installed roof protection pads
More Design Options
The clawFRplus platform offers single (5 and 10 degree) and dual tilt (10 degree) options and supports a range of installation types, including ballast only, fully attached, or hybrid (depends on site conditions).
- Platform is available in single tilt (5 or 10 degree) and Dual Tilt (10 degree) with multiple row spacing options
- Best roof coverage ratios at every tilt angle
- All the strength benefits of a rail based design configurable one module at a time (2 modules at a time for dual tilt)
- More localized wavy roof flexibility than any rail based design in the market (+-3 degrees opposing slopes accommodated)
- Universal, patent pending, module agnostic module attachment method for framed modules
- Reduced racking overhang increases roof coverage ratio and enhances array aesthetics
- Available as ballast only, fully attached, or hybrid (based on site requirements and conditions)
Superior O&M Features
clawFRplus provides exceptional walkway access for simplified construction and maintenance, and features optimal roof anchor attachment points for easy inspection, flexible MLPE securement, 90-degree single module tilt-up, and superior corrosion resistance at no extra cost.
- Best walkway access for every row spacing option makes construction and maintenance of the system easier than with any other flat roof mounting solution
- Superior corrosion resistance with no price premium (ZAM coating delivers 3x to 5x better corrosion resistance than G90)
- Optimally placed, visible mechanical attachment locations for ease of inspection with modules installed
- MLPEs mounted under modules with QR codes visible even after modules are hung
- 90 degree single module tilt up feature
- Redundant module level bonding and grounding makes single module replacement simple
Product Configurations
The 5 degree flat roof geometry is one of the toughest in solar to install. We addressed all these challenges and delivered an industry leading solution for projects that require the highest energy density.
Row Spacing Options
6.9” Row Gap yields 87% roof coverage
10.4” Row Gap yields 82% roof coverage

System Components
Base
Supports the Module Connector and features rubber pads to protect the roof and prevent system movement
Cam & Cam Claw
Tool-less bracket and claw for securing the low side of the module, optimized for large format modules
M6 Bolt
Universal fastener for assembling system components and for attaching some wire management accessories
Module Connector
Cross module assembly with pre-installed Tilt Arm and Lock Claw for securing high side of the module
Rail
Grid element positioned perpendicular to Module Connectors for system rigidity and to support ballast
Wind Deflector
Attaches to Tilt Arm in single tilt product configurations; decreases ballast requirements by equalizing wind pressures

clawFR Platform Tech Tips
The clawFR Legacy Lives on!
We recommend using clawFRplus for all new projects, however, our original flagship clawFR flat roof racking system is still fully supported by PanelClaw.
Domestically Made
We have over 15 years of experience manufacturing flat roof products in the US with an annual capacity of 1.5 GW.
