MOUNTING INSTRUCTIONS
7.1 Mounting methods
PV modules can be mounted to the substructure using either corrosion-proof M8 bolts placed through the
mounting holes on the rear of the module or specially designed module clamps.
Regardless of the fixing method the final installation of the modules must ensure that:
•
A clearance of at least 115mm is provided between modules frame and the surface of the wall or roof.
•
The minimum distance between two modules is 10 mm.
•
The mounting method does not block the module drainage holes.
•
Panels are not subjected to wind or snow loads exceeding the maximum permissible loads, and are
not subject to excessive forces due to the thermal expansion of the support structures.
A. Fixing With Bolts
The frame of each module has 4 x φ9mm mounting holes, ideally placed to optimize the load handling
capability, to secure the modules to supporting structure.
•
To maximize mounting longevity, Sapphire Solar strongly recommends the use of corrosion proof
(stainless steel) fixings
•
Secure the module in each fixing location with an M8mm bolt and a flat washer, spring washer and
nut as shown in Figure 1 and tighten to a torque of 16 Nm.
