INTRODUCTION

Thank you for choosing REC photovoltaic panels for your installation. REC Alpha 72 Series solar panels are ideal for delivering long-lasting and 

reliable power output. They have been created through intelligent design and are manufactured to the highest quality and environmental standards. 

With correct installation and maintenance, REC panels will provide decades of clean and renewable energy.
Please read this entire manual carefully. It contains critical information on safety, as well as detailed instructions for the installation, operation and 

maintenance of the panels. Failure to follow these procedures will invalidate the warranty (www.recgroup.com/warranty). Review all instructions 

and safety notes in this manual before working on the system. Failure to do so may lead to injury or damage to property.

HOW TO USE THIS MANUAL

This manual describes the procedures for the terrestrial installation of all REC Alpha 72 Series solar panels of a ‘72-cell size’ certified according to 

IEC 61215 & IEC 61730 standards. This includes all product variants (indicated by the appropriate suffix in the panel name) e.g., a white or black 

backsheet. The installed panel is considered to be in compliance with IEC 61215 & IEC 61730 only when mounted in the manner specified by this 

installation manual. Note that any panel without a frame (laminate) is not considered to comply with the requirements of IEC 61215 & IEC 61730 

unless mechanically installed with hardware that has been tested and evaluated with the panel under this standard or by a field inspection certifying 

that the installed panel complies with the requirements of IEC 61215 & IEC 61730.
Except where specifically stated, the information and drawings in this manual refer to all frame, backsheet, and cell types; the illustrations are 

only  a generic representation of the instructions regardless of color or exact design. Throughout the manual, you will see sections which highlight 

important information or notes:
