REC Installation Manual - REC Alpha 72 Series  - IEC 61215 /61730
Rev A - 02.20 

Ref: NE-06-23

DRAINAGE HOLES

In each corner of the REC frame small drainage holes are spaced 60 mm from the corner on long and short sides (fig. 7). These allow humidity 

caused by rain, condensation, snow melt, cleaning or any other process to exit the frame easily and minimize damage. These holes must not be used 

for mounting the panel, and they must not be covered by any part of the mounting structure.

 

To enable effective drainage and ensure there is no 

damage to the panel, the drainage holes must remain fully open and enable water egress during and after installation. The shape and dimensions of 

the drainage holes may vary depending on product and/or frame design.

GROUNDING

Local regulations may require grounding of the panels. Grounding must be done using an electrical connection from the panel frame. REC solar 

panels have a small round grounding hole positioned near each corner of the panel on both the long side and the short side, 

as shown in fig. 9 and 

can be further

 identified by the grounding symbol stamped in the frame next to it. Check all applicable requirements before beginning installation:

•  Suitable grounding clips, lugs or other constructions must be used,
•  Attach grounds to the grounding holes in the panel frames,
•  Follow the grounding device manufacturer’s installation instructions to ensure a safe and conductive connection, including any 

supplementary hardware, e.g., star washer, and tighten according to recommended torque,

•  Where common grounding hardware (nuts, bolts, star washers, split-ring lock washers, flat washers and the like) are used to attach a grounding 

device, the attachment must be made in conformance with the grounding device manufacturer’s instructions.

NOTE

•  To avoid galvanic corrosion, galvanized or hot dipped zinc plated fasteners are preferred, however stainless steel fastening materials are 

equally suitable.

•  The support bars across the rear of REC Alpha 72 Series panels are connected to the frame via specially designed grounding clips and do not 

need to be individually grounded. 

•  Negative grounding of the panels is not required by REC.
