Easy, safe and reliable: Sun Ballast’s racking are UL2703-Listed by CSA Group!

Sun Ballast’s team is proud to announce that our ballasted flat roof racking system has earned UL2703 listing by CSA Group, a milestone that underscores our commitment to safety, performance, and innovation in solar racking solutions.

This certification represents compliance with one of the solar industry’s most rigorous standards, covering key aspects of racking system performance and ensuring long-term reliability for solar installations.

Since the very beginning, Sun Ballast’s mission has been not only to provide industry professionals with a faster and easier-to-install solution but also to deliver a system that is safe, reliable, and built to last. Obtaining this certification is a significant milestone, offering our customers added confidence in the quality and performance of our flat roof racking systems.

UL2703: What It Is and Why It Matters

UL2703 is the definitive safety standard for photovoltaic (PV) module mounting systems, addressing critical elements such as:

• Grounding and Bonding: ensures proper electrical continuity and prevents potential hazards. Our system provides integrated grounding and bonding for a streamlined installation process, reducing the need for additional hardware.
• Mechanical Load Testing: verifies structural integrity under various environmental conditions, including snow, wind, and seismic forces, ensuring robust performance in diverse applications. Thanks to their construction features, our ballasted racking systems (wind tunnel tested by RWDI) provide exceptional resistance even without roof penetration, not even along the perimeter of the photovoltaic system. This is a significant advantage that reduces installation time and complexity while preventing any damage to the building’s roof.
• Fire Resistance: Certifies compliance with stringent fire safety requirements, making our system a reliable choice even in areas with high fire risk.

Achieving UL2703 certification assures installers, building owners, and stakeholders that our system meets or exceeds industry standards for safety and durability.

Extensive List of Approved Modules

Our UL 2703 certification includes an extensive list of over 300 approved PV modules – continuously updated with the latest models on the market – ensuring seamless compatibility with a wide range of manufacturers and models. This extensive coverage provides installers with greater flexibility when selecting modules for their projects, eliminating guesswork and ensuring confidence in every installation. The use of our ballasted racking systems allows for the construction of photovoltaic systems with panels of any size – including large-format modules – while guaranteeing maximum reliability in all scenarios, for both the professionals installing the system and the end customer.

Why This Matters for Installers

For professional solar installers, the UL2703 listing offers several practical benefits:

1. Simplified Code Compliance: Our system is fully NEC-compliant, making inspections and approvals faster and more straightforward.
2. Streamlined Installations: Integrated features such as pre-assembled components and built-in grounding reduce installation time and labor costs.
3. Enhanced Safety: Tested for fire resistance and electrical continuity, our racking system enhances overall system safety, protecting both personnel and equipment.
4. Versatile Applications: With a design that meets ASCE 7-16 and SEAOC PV2 guidelines for ballast and wind load calculations, our system is suitable for a variety of roof types and climates. Additionally, the continuous support provided by Sun Ballast’s Technical Office ensures maximum safety and high performance for all our customers.

A Commitment to Quality and Innovation

Our mission is to deliver products that combine safety, durability, and performance with practical benefits for installers. The UL2703 listing by CSA Group validates our dedication to quality, ensuring that our ballasted flat roof racking system meets the highest standards in the solar industry, while also providing designers and installers of photovoltaic systems with tangible advantages in terms of ease of use and overall performance.
