Safety and Installation Manual
Open Renewable PV modules supports two different mounting methods:
5.1
Method “A”
➢
Method “A” is only applicable to modules equipped with 1
st
and 2
nd
generation frames. Please consult drawing 4
or contact your sales representative to determine which frame equips your module.
➢
Modules shall be mounted using 4 holes located on the rear side of the long frame parts. Use 4 M6 stainless
steel bolts per PV module, with nuts, washers and lock washers see drawing 1).
5.2
Method “B”
➢
The selected mounting structure shall be sufficiently-dimensioned, load-bearing and permanently corrosion-
resistant.
➢
The solar module must be aligned in such way to avoid any total or partial shadowing of the module, even
temporary. Shadowing may lead to damage the solar modules, failure of the PV generator and loss of output.
➢
The modules must be attached to the substructure without tension and deformation at no less than four points,
and the clamp surface per attachment point on the module must be at least 750 mm².
➢
The centreline of the clamps should be centred with the area marked as per drawing 3. Some models have a
pre-printed mark on the frame, for easier mounting.
➢
Follow the mounting instructions of the substructure manufacturer. Use appropriate tools and ensure the torque
is within the manufacturer specified range for the module fixing clamps and other screw connections.
➢
The additional loads which arise by way of the weight and the structural attachment of the PV system are to be
included in the structural analysis of the overall construction.
➢
Attachment with clamps on the narrow sides of the solar module may not be performed.
➢
Attach the solar modules so that they with-stand all foreseeable loads and weather-induced influences.
➢
The substructure and the solar module must have the same heat-expansion coefficient as the aluminum frame.
Contact corrosion between the solar module and the substructure is to be avoided when different materials are
used. Lightning protection is recommended according to local regulations.
➢
The solar module may not stand in tail water or condensation water.
