Nuance Energy’s Ground-Mount System Nets UL 2703 Certification


California-based Nuance Energy, manufacturer of the patent-pending Osprey PowerPlatform ground-mount racking system and developer of distributed solar projects through its AgWell Solar division, has received certification for conformance with the Underwriters Laboratories (UL) 2703 standard. The company says Intertek, a nationally recognized testing laboratory, performed the independent testing needed for its ground-mount system to receive ETL-listed compliance with the standard.

UL 2703 is the Standard for Mounting Systems, Mounting Devices, Clamping/Retention Devices, and Ground Lugs for Use with Flat-Plate Photovoltaic Modules and Panels. According to Nuance Energy, certified conformance enables the racking and ground-mount foundation to provide the electrical grounding and bonding for solar modules certified under the UL 1703 Standard for Flat-Plate Photovoltaic Modules and Panels, eliminating the need to install separate ground wiring and rods. For the Osprey PowerPlatform, the connecting cable or rod used in the earth anchor foundation system is what provides the electrical grounding for the array.

Jono Stevens, Nuance Energy’s co-founder and executive vice president, says the UL 2703 certification “will further simplify the installation effort” of the company’s Osprey PowerPlatform. Stevens adds, “Running the wires for the DC and AC connections is also simplified by the Osprey’s design, which makes the wiring channels an integral part of the framework.”
