The new S-5-PV Kit is one of the first solar module mounting solutions in the industry to be listed to the new UL subject 2703, a standard that covers both bonding and mounting. In order to meet the UL requirements, the S-5-PV Kit had to be submitted for tests, being evaluated under the severest of conditions to confirm that the product would withstand the elements while maintaining electrical conductivity.
Furthermore, the S-5-PV Kit has gained an ETL Listing to UL 1703. UL and ETL listings are widely recognized by most Authorities Having Jurisdiction, which means fewer inspection hassles for installers.
Previously, electrical continuity between modules (called “bonding” within the industry) required the mounting of an electrical lug to each PV module, and interconnection of the lugs with a copper wire. However, the S-5-PV Kit’s groundbreaking NEW stainless steel mounting disk has twelve nodes designed to ensure the module-to-module conductivity of anodized aluminum module frames.
With the new S-5-PV Kit, the module is simply anchored with the kit and automatically provides a ground path in the module frame. No lugs or wire required except to connect one string of modules to another and to ground the system. This connection detail represents installed electrical cost savings of $6-$12 per unit.
In most cases, the savings in time and materials is sufficient to pay for the entire S-5-PV Kit and clamp setup! The S-5-PV Kit continues to be the easiest, most cost-effective way to install solar panels directly to standing seam metal roofs and remains the most popular choice worldwide.
