iii) Clamp mounting positions
REC TwinPeak panels can be fixed on both the long and the short side of the panel within the constraints shown in fig. . The panels are built to
withstand a downward force of up to Pa ( kg/m) or Pa ( kg/m) according to where they are clamped. Site-specific loads
such as wind or snow which may exert forces in a different way need to be taken into consideration to ensure this limit is not exceeded for each
respective mounting option.
Clamping within the green zone ( - mm) is certified for design loads up to Pa ( kg/m)
Clamping within the yellow zone ( - mm long side, mm short side) is certified for design loads up to Pa ( kg/m)
Clamping within the red zone is not permied (> mm long side, > mm short side).

A minimum of four clamps must be fully located in the same colored zone to be certified to that value. If the panel is secured by
four clamps in two different zones (i.e., green and yellow), it is certified to the lowest value only.

iv) Mounting holes
REC TwinPeak panels can be secured to the mounting structure using the mounting holes found on the underside of the frame (. x mm,
spaced mm from the midpoint of the long side) (fig. ). The panels can withstand a downward force of up to Pa ( kg/m) when
secured using the mounting holes. Bolts of size mm secured with mm locking nuts with a flange should be used to secure the frame to the
mounting structure (fig. ). Observe the following procedures when using mounting holes:
• The mounting construction should be of aluminium or galvanized steel to avoid galvanic corrosion and be appropriate for the local
environment.
• Additional electrical bonding to Ground is required for the support structure (see Grounding).
• All four mounting holes in the frame must be used.
• Tighten fastenings using a torque wrench according to the understructure manufacturer’s instructions.
The product warranty will be voided if additional holes are made in the frame. All fixing and fastening materials must be corrosion
resistant.
v) Slide-in Systems
REC TwinPeak panels may also be installed using slide-in systems. Such mounting systems must meet the same specifications regarding grip
lengths and depths as clamps and be able to withstand the correct load pressures. When installing with slide-in systems, the drainage holes
(fig. ) must not be covered. For any questions regarding installation on such systems, please contact REC directly.
