The new stainless steel photovoltaic mounting disc is designed to ensure conductivity with anodized aluminum module frames. Because of this, the S-5! PV Kit will further reduce installation costs. The disc provides module-to-module electrical continuity, also known as bonding. Previously this was accomplished by connecting modules with ground lugs and copper wire. This connection detail represents installed electrical costs of $6 to $12 per unit. With the new kit, the module is simply anchored with the kit and is automatically bonded. No lugs or wires are required from module to module. Wires or lugs still will be needed to bond strings together and to ground the system. Additionally, the kit’s stainless steel construction withstands weathering and facilitates use with brass clamps.
