Solar Racks and Trackers

Solar Racks and Trackers – Qualification Services

TÜV Rheinland qualification provides assurances sought by regulators, EPCs and installers for structural integrity and robustness of PV, CPV and concentrating solar thermal systems. Based on existing standards and codes, as well as emerging draft standards and industry accepted protocols, test programs are available to provide third party proof of conformance to known structural safety requirements and guidelines for North American and International installations.

Using published international regulations and codes, TÜV Rheinland can provide manufacturers of PV mounting racks and tracker components with the conformance proof needed to meet the expected safety and reliability requirements for most markets. The addition of North American draft standards UL Subject 2703 and UL Subject 3703, manufacturers can also show compliance with requirements for North American installations.

Our goal is to provide clients with the most comprehensive and accurately measured structural/performance characteristics for mounting and tracking systems, delivering greater confidence in system reliability and robustness to all project stakeholders. Join the growing list of our customers, who already take advantage of our comprehensive range of services and our global presence.

Our Approach

Typical test programs for racking and tracking products and systems include the following steps:

  • Determine your target markets and locations
  • Assess project for appropriate standards, codes, and other requirements
  • Develop the right test program for the relevant standards, codes, and test methods
  • Execute testing program
  • Develop and deliver test reports and other relevant proof of compliance
  • Provide field assessment of the system, where needed

Test Program for Assessing Requirements

TÜV Rheinland integrates requirements from multiple standards, codes, and guidelines (published and preliminary drafts) to determine the right test program for each product or system. Where needed, experienced test personnel can also apply appropriate “lessons-learned” and industry “best-practices”.

Due to site-specific considerations and regional codes, it is important to recognize that the testing done by TÜV Rheinland cannot ensure full acceptance with all local authorities and their jurisdiction. In many cases, additional testing is required for specific installations.
