How Aluminium Middle Clamps Work

Each clamp is designed to lock between the edges of adjacent solar modules on mounting rails. When torqued to spec, clamps prevent panel shift and create a distributed holding force along the array. A typical installation sequence:

1. Insert clamp into rail channel at the correct position
2. Align solar panel edges with clamp faces
3. Hand-tighten then torque bolts to manufacturer guideline (commonly 8-10 Nm for M8 hardware)

Choosing and Installing Your Aluminium Middle Clamp

Selection Criteria

• Confirm clamp size supports your panel’s frame thickness (most panels: 35 mm)
• Choose mounting hardware compatible with your rail type (T-slot, click-in, or sliding nut designs)
• Prefer anodized or corrosion-treated aluminium for South African outdoor conditions
• If sourcing in bulk, match clamp supplier/brand for consistent finish and fit

Example Calculation

For a 6-panel (3x2) array using standard 35 mm frame thickness:

• Panels = 6, Array columns = 3
• Middle clamps required = (Panels per row - 1) x Rows = (3 - 1) x 2 = 4
• End clamps typically sold separately
