PanelClaw Announces UL 2703 Certification

Wednesday, May 04 2011 00:00

North Andover, MA, May 5, 2011 - PanelClaw, a leader in solar PV mounting systems, announced today UL electrical bonding and grounding certification for its module mounting components (“Claws”). Official recognition to UL 2703 for electric bonding and grounding will drastically reduce grounding costs for solar arrays mounted with PanelClaw’s innovative Polar Bear® FR, Grizzly Bear® FR, and Panda Bear GM flat roof and ground mount solutions.

UL 2703 electric bonding and grounding certification will enable PanelClaw partners to electrically bond modules and ground arrays simply and quickly, lowering labor costs and eliminating the need for thousands of feet of copper wire and the vast majority of module and racking ground lugs. Multiple strings can now be grounded with a single grounding lug when PanelClaw racking is used in conjunction with appropriately UL tested and listed modules.

“UL 2703 will allow our partners to realize significant project savings through simplified array grounding that slashes labor and material costs,” said Costa Nicolaou, PanelClaw’s president. “Partnering with UL is a clear signal to our partners that PanelClaw is committed to the long-term safety and reliability of our racking solutions.”

UL 2703 is a new UL subject that is specifically focused on Rack Mounting Systems and Clamping Devices for PV Modules and Panels. PanelClaw’s module attachment components or “Claws” were subjected to rigorous testing, including temperature and humidity cycling followed by electrical resistance and conductance analysis, to ensure durable electrical bonding in outdoor environments.

“The emergence of UL 2703 allows PanelClaw and other mounting system companies to demonstrate the effectiveness of racking systems and quality of manufacturing and operational processes,” said Mark Gies, PanelClaw’s vice president of technology and innovation.  “We look forward to the evolution of UL 2703 to a standard, and to the continued validation of our products.”

Modules must undergo simple conductivity and load testing with PanelClaw mounting products prior to being added to PanelClaw’s UL certification.  If you are interested in having your preferred PV modules added to PanelClaw’s UL 2703 certification or learning more about PanelClaw’s products and services, please contact PanelClaw at (978) 688-4900 or This e-mail address is being protected from spambots.
