INTRODUCTION

Thank you for choosing REC photovoltaic panels for your installation. REC 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 clean, renewable energy for many years.
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 (available to download via www.recgroup.com/warranty). 

Review all instructions and safety notes before working on the system. Failure to do so may lead to injury or damage to property.

HOW TO USE THIS MANUAL

This installation manual describes the procedures for the terrestrial mounting in a photovoltaic array of all REC solar panels of a ‘72-cell size’ 

certified according to IEC 61215 and IEC 61730 standards. This includes all product variants (as indicated by the use of the appropriate suffix in 

the panel name) with a white, black or transparent backsheet, a silver or black frame, multicrystalline or monocrystalline cells. The installed panel 

is considered to be in compliance with IEC 61215 and 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 and 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 and IEC 61730.
Except where specifically stated, the information and drawings within this manual refer to all frame, backsheet, and cell types; the illustrations are 

meant to be a generic representation of the instructions detailed in the text regardless of the color depicted. Review this entire manual before 

commencing installation of the panels and ensure you are working from the latest version. Throughout the manual, you will see icons which highlight 

important information or notes:

Indicates potential for damage to the array, property or personal safety.

Indicates important notes on best practice to help with the installation.

For further information on installation procedures, please call your panel distributor or contact your local REC Solar office. Details can be found at:
