REC Installation Manual - REC Alpha Panels - IEC 61215 /61730
Rev 13 - 11.22

MOUNTING METHODS: SLIDE IN SYSTEMS
When installing using slide in systems the mounting system must meet the same specifications including grip lengths, depths and spacing as
specified for clamping and the mounting system must be able to withstand the correct load pressures.
When installing solar panels using a slide-in system, the drainage holes found in the underside of the panel frame (fig. 12) must not be covered. For
any questions regarding installation on such systems, please contact REC directly.
MOUNTING METHODS: MOUNTING HOLES
The REC solar panels covered by this manual can be installed utilizing the four mounting holes (11 x 6.6 mm) on the underside of the panel (fig. 9 &
11) in conjunction with a device, e.g., screws or lockbolts, with specifications suitable for the installation (fig. 10).
Installing REC Alpha solar panels using the mounting holes has been found to comply with IEC 61215 & IEC 61730 requirements for downward
pressure,e.g., snow, of up to 5400 Pa (3600 Pa design load
*
) and upward pressure,e.g., wind, of up to 2400 Pa (1600 Pa design load
*
) according to
the following instructions (
*
design loads apply a safety factor of 1.5 to the stated test load, e.g., test load 5400 Pa / 1.5 = 3600 Pa design load).

CAUTION
The product warranty will be voided if additional holes are made in the frame. All fixing and fastening materials must be corrosion resistant.
When installing using mounting holes, the frame and panel edge of each panel must be supported by two rails
of aluminium or galvanized steel
suitable for the application and appropriate for the local environment.
Observe the following procedures when using mounting holes:
• The mounting construction must be of a corrosion resistant material, e.g., aluminum or galvanized steel, and appropriate for the local
environment,
• All four mounting holes in the frame must be used (fig. 14),
• A washer must be used between frame and rail,
• Additional electrical bonding to Ground is required for the support structure,
• REC modules must be secured with a torque between 12 - 25 Nm.
Refer to the fixing device manufacturer’s installation instructions for
preload or torque values.
