INTRODUCTION Thank you for choosing REC photovoltaic panels. REC TwinPeak solar panels are ideal for delivering long-lasting and reliable power output. The panels 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.
ELECTRICAL INSTALLATION ELECTRICAL REQUIREMENTS i) Application Class REC TwinPeak panels are rated for use in electrical application class A: Hazardous voltage (IEC 61730: higher than 50V DC; EN 61730: higher than 120 V), hazardous power applications (higher than 240 W) where general contact access is anticipated (panels qualified for safety through EN IEC 61730-1 and -2 within this application class are considered to meet the requirements for Safety Class II).
MECHANICAL INSTALLATION FIRE GUIDELINES REC TwinPeak panels have a Class C fire classification. Utilize the following fire safety guidelines when installing REC TwinPeak panels: • • • • • Check with local authorities for fire safety guidelines and requirements for any building or structure on to which the panels will be installed. The system design must ensure that it can be easily accessed in the event of a building fire.
MOUNTING THE PANELS REC TwinPeak panels are designed for capturing solar radiation and are not suitable for installation as overhead or vertical glazing. The junction box on the rear of the panel is protected to IP67 and allows panels to be mounted in any orientation. The panels must be installed so that the cells are not shaded as this will drastically reduce electrical output. If partial shading is inevitable at certain times of the day or year, it must be kept to an absolute minimum.
iii) Clamp mounting positions REC TwinPeak panels can be fixed on both the long and the short side of the panel within the constraints shown in fig. 4. The panels are built to withstand a downward force of up to 5400 Pa (550 kg/m²) or 2400 Pa (244 kg/m²) according to where they are clamped. Site-specific loads such as wind or snow which may exert forces in a different way need to be taken into consideration to ensure this limit is not exceeded for each respective mounting option.
vi) Drainage holes Each corner of the panel frame has small drainage holes (fig. 7) to allow water caused by rain or snow melt to exit the frame easily and to minimize damage caused by freezing and thawing. These must not be used for mounting the panel. Ensure the drainage holes are not covered by the mounting structure. Fig. 7: Drainage holes GR vii) Grounding Local regulations may require grounding of the panels. Check all applicable requirements before beginning installation.
CONNECTIONS AND CONNECTORS The connectors on REC TwinPeak panels are rated IP67 only when 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%). Observe all local regulations when selecting cables.
MAINTENANCE CLEANING INSTRUCTIONS REC TwinPeak solar panels have been designed for easy maintenance. Normal rainfall will naturally clean the panels if installed at a sufficient angle. The need for cleaning will vary dependent on location, rainfall, pollution and angle of installation – the lower the angle of installation, the more cleaning will be required. To optimize electrical output it is recommended to clean the panels when dirt can be seen on the glass surface.

ANNEX 1. USE OF POWER OPTIMIZERS Panels of the REC TwinPeak IQ Series only have been certified according to IEC 61215/61730 and UL 1703 for use with pre-installed power optimizers. When installing REC TwinPeak IQ Series panels, care must be taken to ensure a safe and correct panel installation. When installing REC TwinPeak IQ Series panels, follow the instructions below specific for such applications in addition to the above module mounting instructions.
ANNEX 2. INSTALLATIONS ON WATER PLATFORMS REC TwinPeak panels have not been certified for installation on water platform-type mounting systems. When installing REC TwinPeak 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.
