• The required minimum length of a clamp (parallel

to the frame side) is 30 mm.

• The required minimum length of a clamp (parallel to

the frame side) is 30 mm.

• The required minimum depth of a clamp

(perpendicular to the frame side) is 3 mm.

• The required minimum depth of a clamp (perpen-

dicular to the frame side) is 3 mm.

• aleo solar recommends a clamp depth of 5 mm.

Screw mounting

10.4.1 Modules with standard frames

The aleo modules have mounting holes with a diameter of

9 mm

The total length is 22.5 mm. The distance between the hole centres is 13.5 mm.

This applies to unlubricated screws with standard thread and strength class of 8.8

(minimum breaking load 29.2 kN).
