IronRidge XR Solar Panel Ground Mount System
Cost-Effective All-Terrain Mounting
The IronRidge Ground Mount System combines engineered XR100® or XR1000® aluminum rails with locally-sourced steel pipes or mechanical tubing to create a robust, cost-effective structure capable of handling any site or terrain challenge. This system works seamlessly across both residential and commercial applications.
Installation is simplified with only a few structural components and no drilling, welding, or heavy machinery required. The system supports multiple foundation options including concrete piers, ground screws, helical piles, driven piles, and above-ground ballast blocks, making it compatible with soil classes 2-4 and various site conditions.
Rugged Construction
Engineered steel and aluminum components manufactured from 6000-series aluminum alloy ensure long-term durability and structural integrity.
UL 2703 Listed
Complete system and components meet the newest effective UL 2703 standard for photovoltaic mounting systems.
PE Certified
Pre-stamped engineering letters available in most states, simplifying permitting and approval processes.
Flexible Architecture
Multiple foundation and array configuration options accommodate various site conditions and installation requirements.
Simple Installation
Only a few structural components required with no drilling, welding, or heavy machinery needed for installation.
25-Year Warranty
Products guaranteed to be free of impairing defects with comprehensive manufacturer warranty coverage.
Aluminum Rail Systems Engineered for Strength
XR Rails feature a unique curved profile that increases structural strength and spanning capability, meaning fewer roof penetrations and more cost-effective designs for both residential and commercial applications. Available in Mill finish aluminum, or black anodized aluminum. Clear Anodized is available as a special order.
XR100® Rail
This ironridge mounting rail support a range of wind and snow conditions while maximizing spans up to 8 feet. Perfect for both residential and commercial installations requiring heavy load capability.
XR1000® Rail
A heavyweight among solar mounting rails, built to handle extreme climates and spans up to 12 feet. Engineered for both residential and commercial applications requiring maximum structural performance.

Multiple Foundation Options for Any Site Condition
The IronRidge Ground Mount System supports various foundation methods to accommodate different soil conditions, site requirements, and project specifications. Choose the optimal foundation type for your installation.
Standard Foundation Methods
Concrete Piers
Poured concrete piers provide excellent resistance to vertical and lateral loads, constructed with readily available materials.
Key Benefits:
- Excellent load resistance
- Readily available materials
- Standardized design options
- Backed by stamped engineering letters
Ground Screws
Ground screws are gaining popularity for their versatility, quick installation, and low impact on land drainage.
Key Benefits:
- Quick installation process
- Low impact on land drainage
- Compatible with Krinner G-Series
- Certified systems engineering letter available
Alternative Foundation Methods
For specialized site conditions or project requirements, the Ground Mount System can be installed using alternative foundation methods. Each method requires professional engineering analysis.
Helical Piles
Provide very good resistance to uplift forces but minimal lateral load resistance compared to standard concrete foundations.
Engineering Considerations:
- Requires Professional Engineer (PE) analysis
- Shorter E-W pier spans required
- More piers needed for stability
- Additional bracing may be required
Driven Piers
Pile-driven or vibratory-driven piers require specialized equipment and analysis of soil bearing capacity and corrosivity.
Project Requirements:
- Geotechnical Engineer soil analysis
- Specialized installation equipment
- Deeper foundations required
- Custom PE foundation design letter
Ballasted Systems
Common for brownfield sites like landfills where cap layers cannot be penetrated. Can be cast-in-place or pre-cast concrete blocks.
Application Benefits:
- Ideal for brownfield/landfill sites
- No ground penetration required
- Cast-in-place or pre-cast options
- PE determines block sizing requirements
