Page 3: How To Use This Manual
HOW TO USE THIS MANUAL This installation manual describes the procedures for the terrestrial mounting of all REC solar panels of a ‘72-cell size’ of the REC Peak Energy and REC TwinPeak product families (as indicated by the use of the suffix 72 in the panel name) certified according to the UL 1730, IEC 61215 and UL 61730 standards in a photovoltaic array. -
Page 4: Safety Measures
PANEL HANDLING To avoid damage to the solar cells and other components, all REC solar panels should be handled with care and protected from damage at all times. All warnings and instructions on the packaging should be observed. Follow these guidelines when unpacking, transporting or storing panels: •... -
Page 5: Electrical Installation
System Requirements REC solar panels are only for use where they meet the specific technical requirements of the complete system. Ensure other components will not cause mechanical or electrical damage to the panels. Only panels of the same type and power class should be connected. -
Page 6: Mechanical Installation
The solar panels must not be exposed to artificially concentrated light. ENVIRONMENTAL FACTORS REC solar panels are designed to provide decades of durable and stable output in installations up to 6500 ft (2000 m) above sea level. Ambient operating temperatures must be between -40° and +185°F (-40° and +85°C). -
Page 7: Panel Installation
RAIL SPECIFICATIONS REC solar panels are typically installed on a rail-based mounting system (fig. 1). Installers must ensure that the rails are suitable for the system design and expected design loads. If using mounting rails, ensure they run parallel to the frame (fig. 2) or across the module, underneath the frame (fig. 3) and that rails are positioned directly under the module clamping zones shown on the subsequent pages. -
Page 8: Clamp Specifications
CLAMP SPECIFICATIONS REC modules must be secured with a torque between 106-221 lbf/in (12 - 25 Nm). REC TwinPeak 2S Mono 72 panels have been evaluated by UL for mounting using rails in combination with end and mid clamps, ASTM F593C stainless steel screw and rail nuts with the below ratings and dimensions. - Page 9 (fig. 6). • REC modules must be secured with a torque between 106 - 221 lbf/in (12 - 25 Nm). Clamp installation must be carried out according to the manufacturer’s instructions, including specific hardware and torque requirements. Fig. 6: Clamping Zones on continous rails: REC TwinPeak 2S Mono 72, REC Twinpeak 3S Mono 72 (measurements in diagram shown in in [mm]) 26.4 in [670 mm]...
- Page 10 Mounting using clamps: Long side The above named REC 72-cell product families can be secured with short rails using clamps where both clamps and rails are located within the constraints shown in fig. 7. Mounting with short rails utilizing clamps has been found to be in compliance with UL 61730 requirements for design loads up to 19.5 psf (993 Pa) downwards and upwards force according to the clamping position.

Page 11: Drainage Holes
TwinPeak 2S 72 Scale 1:1 All REC 72-cell panels have been certified for installation using the four elongated holes 0.43 x 0.26 in (11 x 6.6 mm) on the underside of the panel 04.10.16 frame at a distance of 18.1 in (460 mm) from the short side edge (fig. 8), utilizing rails and bolts matching the specifications in fig. 9. Installation of REC 72-cell panels using mounting holes complies with UL 61730 requirements for a maximum downward design load of 72.2 lbs/ft²... -
Page 12: Grounding
National Electrical Code. When grounding a panel, it must be done using an electrical connection from the panel frame. REC solar panels have a clearly marked, small round Ø 6 mm grounding hole positioned near each corner of the panel to aid in grounding as shown in fig. -
Page 13: Cables, Connections And Connectors
CONNECTORS The exact connector type used on REC solar panels is indicated in the product specifications at the rear of this manual. The stated IP rating is only valid when correctly mated. To ensure connector compatibility and reduce the potential for damage to the modules and the installation, mated connectors must be from the same manufacturer and of the same (i.e., mateable) connector type and system rating. -
Page 14: Maintenance
RECYCLING REC makes every effort to ensure panel packaging is kept to a minimum. The paper and cardboard packaging can be recycled and the protective wrapping and panel separating blocks are also recyclable in many areas. Recycle packaging and modules according to local guidelines and regulations. -

Page 17: Annex 1: Installations On Water Platforms
The above named REC solar panels may be installed on water platform-type mounting systems (note that the UL 1703 and UL 61730 certification testing of solar panels does not include testing on these types of systems). When installing any of the above named REC solar panels on fixed position (e.g., anchored) water platforms, for example, floating pontoons, follow the instructions below specific to such applications. -
