UL Standards
for safer, smarter solar
From rapid shutdown to waterproofing, Unirac’s solar mounting systems are rigorously tested and nationally certified to keep your project on time, on budget, and code compliant.
Nationally recognized UL certifications back Unirac’s commitment to safety, durability, and compliance. Whether you’re designing residential rooftops or large-scale commercial systems, you can build with confidence, knowing your system meets the industry’s most demanding standards.
Why UL Listings Matter
UL certifications are more than a stamp of approval—they’re proof that your system has been tested to perform under real-world conditions. These certifications validate everything from electrical and fire safety to structural strength and waterproofing. For installers, AHJs, and building owners alike, UL listings streamline approvals, reduce risk, and deliver peace of mind.
Photovoltaic Hazard Control Compliance
Code-Compliant Safety Without Complexity
UL 3741 defines a new path to meeting NEC 690.12 rapid shutdown requirements—without relying on module-level power electronics (MLPEs). Instead, it certifies that the racking system, inverter, and conductors work together to quickly bring voltage to safe levels inside and outside the array.

why UL 3741 matters
UL 3741 enables you to meet code while eliminating unnecessary complexity, cost, and maintenance. Fewer components mean fewer failure points—and safer systems for both installers and first responders.
UL 2703
Structural, Grounding & Fire Safety
Achieving UL 2703 compliance certifies that Unirac’s racking systems meet national standards for electrical grounding, structural integrity, and fire safety. UL 2703 ensures that components don’t degrade due to harsh environments and don’t utilize incompatible component materials since contact that can prematurely degrade. It verifies that systems withstand wind uplift, snow loads, and seismic activity—all while maintaining a safe path for electrical bonding and grounding.
With UL 2703, you get pre-engineered assurance that your system is ready for permitting, inspection, and long-term performance. It’s also a key requirement for insurance and finance partners who demand proven reliability.
UL 2703A
Flashless Attachments: Waterproofing You Can Trust
UL 2703A is the new benchmark for roof attachment flashing, particularly for polymer and butyl-based products used on low-slope or membrane roofs. It tests for tear strength, UV exposure, thermal cycling, impact strength, and water penetration to ensure long-term waterproofing performance.
Unirac’s attachments, such as Stronghold® Butyl, SolarMount® Butyl, and SFM Butyl, are engineered to protect your projects from costly leaks and callbacks. It’s the peace of mind contractors and building owners count on.
