6.4 Module Mounting Instructions
Mounting Structures Cautions
• Pay attention to the electrochemical series when selecting support structure material to avoid galvanic corrosion.
• Fasten and lock bolts completely. Inadequate mounting may result in SF modules falling or other accidents.
• Ensure that the SF modules are securely fastened to the mounting support structure that is durable, made of corrosive and UV
resistant material, and follow the applicable local and civil codes.
• Ensure, that your mounting support structure is designed to withstand the SF modules design snow and wind loads applicable for
your chosen site. Solar Frontier will not be responsible if the SF modules are damaged due to the durability of the mounting sup-
port structure. Consult your mounting structure manufacturer for an appropriate mounting design.
Mounting the Solar Modules
• PV modules should typically face South in the Northern Hemisphere and North in the Southern Hemisphere for optimal
power production.
• Modules can be installed horizontally (landscape) or vertically (portrait).
• Maintain a space between SF modules and the roof. This will allow air to circulate, cooling the module, and
allowing condensation to dissipate. Solar Frontier recommends a distance of at least 100 mm.
Mounting with Screws
SF modules should be fastened to the support structure using the mounting holes on the frame. The support structure
should be securely fastened to a non-corrosive roof. Tighten the screws with an adequate torque value. Please refer to further instruc-
tions and adequate torque value provided by the screw manufacturer.
Mounting with Inner Holes
Each module will require four M6 (or 1/4 in) bolts with washers, lock washers and nuts. Tighten the screws with an adequate torque value.
UL:
Recommended tightening torque is 8 Nm (70.8 lb in) minimum.
TUV: 2,400 Pa (50 lbs/ft
2
) to the front and back of the module
UL: 1,600 Pa (33.4 lbs/ft
2
) to the front and back of the module
1.5 times the design load is applied to the module during UL testing. 2,400 Pa (50 lbs/ft
2
) is applied to test 1,600 Pa
(33.4 lbs/ft
2
) UL design load.
