In this complete guide, we’ll examine everything from technical specifications to real-world performance, helping you make an informed decision for your residential solar panel installations.
What is the Unirac SolarMount System?
The Unirac SolarMount is a rail-based pitched roof mounting system designed specifically for residential solar panel installations. Unlike basic mounting solutions, SolarMount integrates universal components, advanced flashing technology, and aesthetic enhancements to create what many consider the most professional-grade residential mounting system available.
Key benefits that set SolarMount apart:
- Universal clamps compatible with multiple panel types and thicknesses
- FlashKit Pro attachment system for superior weatherproofing
- Full UL 2703 certification for electrical safety
- 25-year limited warranty backed by Unirac’s financial stability
- Best-in-class aesthetics with optional trim components
Unirac SolarMount System Components
Understanding the SolarMount component ecosystem is crucial for proper system design and installation. Each component serves a specific purpose in creating a secure, weatherproof, and aesthetically pleasing solar array.
Universal Clamps and End Caps
The heart of the SolarMount system lies in its revolutionary universal clamp design. These clamps accommodate panel thicknesses from 30-50mm without requiring different hardware, significantly reducing inventory requirements and installation complexity.
Available clamp options:
- Standard Universal Clamps: Basic functionality for most installations
- Pro Series Clamps: Enhanced features for demanding applications
- UAF (Universal Attachment Fitting) Clamps: Maximum compatibility across panel manufacturers
Rail Systems
SolarMount rails are available in three standard lengths to accommodate various array configurations:
- 132″ Rails (Model 320132M): Ideal for smaller residential arrays
- 168″ Rails (Models 310168C/D, 320168M): Most popular length for standard installations
- 246″ Rails (Models 315246M, 320246M): Extended length for large arrays and commercial applications
Rails are available in mill finish aluminum, clear anodized, and dark anodized finishes. The Light Rail option (315 series) offers reduced weight while maintaining structural integrity for installations where roof loading is a concern.
FlashKit Pro Attachment System
The FlashKit Pro represents Unirac’s advanced approach to roof penetration waterproofing. This system integrates multiple weatherproofing technologies:
- Integrated flashing with advanced sealant technology
- Structural lag bolt attachment for maximum holding power
- Compatible with composition, architectural shingle, and tile roofing
- Pre-assembled components reduce installation time
Trim and Aesthetic Components
SolarMount’s optional trim system (Model 206072D-B and similar) provides a finished appearance that enhances curb appeal:
- Front trim pieces available in 168″ lengths
- Black and mill finish options to match rail selection
- No special brackets required for installation
- Creates clean, streamlined edge appearance

Installation Guide & Best Practices
Pre-Installation Planning and Roof Assessment
Successful SolarMount installation begins with thorough planning and assessment. For comprehensive preparation guidance, review our professional solar installation process guide:
Structural Assessment:
- Verify roof structural adequacy using span tables and load calculations
- Identify rafter locations using stud finder or probe methods
- Check for adequate clearances from roof edges and penetrations
- Document any roof damage or maintenance needs
Layout Planning:
- Use Unirac’s U-Builder tool for system design and component selection
- Plan rail runs to minimize splicing and optimize structural attachment
- Consider aesthetic factors including trim placement and symmetry
- Verify electrical bonding paths and grounding electrode connections
Step-by-Step Installation Process
Step 1: Mark Attachment Points
Using your approved layout, mark all FlashKit Pro attachment locations. Ensure attachments hit structural members (rafters or trusses) and maintain proper spacing typically 48″ on center maximum.
Step 2: Install FlashKit Pro Attachments
Drill pilot holes using appropriate bit size for your roof material. Install FlashKit Pro assemblies with structural lag bolts, ensuring proper torque specifications (typically 25-30 ft-lbs).
Step 3: Install Rails
Mount SolarMount rails to FlashKit Pro attachments using provided hardware. Check for level and proper alignment before final tightening. Install splice connections where rails join.
Step 4: Install End Caps and Trim
Install end caps on all rail terminations. If using trim system, install trim pieces before mounting panels for easier access.
Step 5: Mount Solar Panels
Install panels using universal clamps, ensuring proper spacing and alignment. Verify electrical bonding connections are secure.
Common Installation Mistakes to Avoid
- Inadequate Structural Attachment: Always hit structural members, never just sheathing
- Improper Sealant Application: Follow FlashKit Pro instructions exactly for weatherproofing
- Incorrect Torque Values: Under-torquing leads to loose connections, over-torquing can damage components
- Poor Rail Alignment: Misaligned rails cause panel installation difficulties and aesthetic issues
- Neglecting Electrical Bonding: Verify continuity across all connections for code compliance
Tools and Materials Needed
Essential Tools:
- Drill with appropriate bits for roof material
- Torque wrench for proper fastener installation
- Level (4-foot minimum) for rail alignment
- Chalk line for layout marking
- Safety equipment including harnesses and roof jacks
Additional Materials:
- Additional sealant for challenging roof conditions
- Splice hardware for rail connections
- Bonding jumpers if required by local code
