S-5!, a provider of metal roofing attachment solutions, has made modifications to its PV Kit, which is used to mount PV modules. The product's new stainless-steel mounting disk is designed to ensure conductivity with anodized aluminum module frames and reduce installation costs, S-5! says.
The new disk provides module-to-module electrical continuity. Previously, this bonding was accomplished by connecting modules with ground lugs and copper wire, which represented installed electrical costs of $6 to $12 per unit. With the new PV Kit, the module is simply anchored and is automatically bonded, the company explains. Although no lugs or wires are required from module-to-module, wires or lugs will still be needed to bond strings together and to ground the system.
The PV Kit is made of stainless steel to withstand weathering and facilitate use with brass clamps, the company adds. The product meets UL-2703 standards.
