Question

how many trim-to-module bonding clamps are required?

• 1 per each contiguous run of trimrail
• 1 next to each trimrail splice
• 1 per module

Explanation:

🆕 New Concept Discovered: Solar Mounting Electrical Bonding
Ensuring electrical continuity across structural rails

Step 1: Understand the Function of the Clamp

In solar photovoltaic (PV) mounting systems (such as Unirac or similar rail-based systems), a "Trim-to-Module Bonding Clamp" is used to establish a reliable electrical ground path (bonding) between the decorative/structural trim rail (Trimrail) and the solar module frames.

Step 2: Determine the Installation Requirement

Because electrical continuity must be maintained across any continuous metal path to ensure safety and proper grounding:

• A single continuous run of Trimrail needs to be electrically bonded to the modules it borders.
• Therefore, you only need 1 clamp per each contiguous run of Trimrail to safely bond that entire continuous section to the system ground through the modules.

Answer:

1 per each contiguous run of Trimrail
