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 decades of clean and renewable energy. Please read this entire manual carefully.
SAFETY MEASURES Installers are responsible for the safe and effective installation and operation of the system and for adhering to all applicable local and national standards and regulations. All relevant local codes and regulations must be referred to and observed. DANGER - Electrical shock Solar panels generate direct current (DC). Once current is flowing, breaking a connection (e.g., disconnecting two panels) can cause an electrical arc.
PANEL HANDLING In order to avoid damage, 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.
ELECTRICAL INSTALLATION DANGER - Electrical shock Safety is paramount when working on the electrical installation. Always follow the electrical requirements to avoid the risk of sparking, fire hazards, burns and lethal electric shocks.
PANEL INSTALLATION REC solar panels are designed for capturing solar radiation and can be installed where they conform to all local structural regulations. If installing REC solar panels in overhead or vertical constructions, the installer must ensure that all local building codes and regulations specific to such installations are correctly followed. There are different options for securing REC solar panels depending on the design of the array. Mounting hardware is not supplied by REC.

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 (see fig. 16) must not be covered. For any questions regarding installation on such systems, please contact REC directly.
MOUNTING METHODS: SIX-POINT MOUNTING A six-point mounting configuration secures the panel on three continuous rails (or other support structures) with three clamps on each side of the panel in the zones marked below: This helps to increase the downward load a panel can withstand, e.g., snow. The third clamp is typically installed in the central area of the panel as shown in Fig. 18: Fig. 18: Six-point mounting configuration clamping zones 100 mm [3.9 in] - 430 mm [16.9 in] 730 mm [28.7 in] - 810 mm [31.
DRAINAGE HOLES On the long and short sides of the REC frame small drainage holes can be found that allow humidity and water to exit the frame easily and minimize damage (fig. 18). These are spaced 55 mm from the corner. 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.
CONNECTIONS AND CONNECTORS The connector type(s) used on REC panels are indicated in the product specifications at the rear of this manual. The connector IP rating is only valid when correctly connected. All connectors and cables must be secure and tight as well as electrically and mechanically sound. UV-resistant cables and connectors approved for outdoor use must be used. Conductor gauge must be chosen to ensure DC power losses (voltage drop) are kept to a minimum (<1%).
PANEL MAINTENANCE CLEANING INSTRUCTIONS REC solar panels have been designed for easy maintenance. However cleaning solar panels can assist in optimizing electricity output. The need for cleaning will vary dependent on location, rainfall, pollution levels and the angle of installation – the lower the angle of installation, the more cleaning will be required. ‘Normal’ rainfall will naturally clean the panels if installed at a sufficient angle to ensure water runs off the surface.

ANNEX 1: INSTALLATIONS ON WATER PLATFORMS The REC solar panels covered by this manual may be installed on water platform-type mounting systems (note that the certification testing of solar panels does not include testing on these types of systems). When installing REC solar panels on fixed position (e.g., anchored) water platforms, for example, floating pontoons, follow the instructions below specific to such applications. Failure to do so will invalidate the warranty.
ANNEX 2: INSTALLATIONS USING MODULE LEVEL POWER ELECTRONICS This section is applicable to all REC products referred to in this installation manual. Module Level Power Electronics (MLPE) is the name given to the range of panel-level components that can be installed in PV system circuits installed on or in buildings to reduce shock hazard for emergency responders. MLPE devices can be supplied pre-installed by panel manufacturers or as a ‘retro-fit’ system made by third-party manufacturers.
