INTRODUCTION Thank you for choosing REC photovoltaic panels. REC Peak Energy 72 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 Peak Energy 72 Series 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 Peak Energy 72 Series panels have a Class C fire rating. The fire rating of this panel is only valid when mounted in the manner specified in these mechanical mounting instructions.
MOUNTING the panels REC Peak Energy 72 Series panels are designed for capturing solar radiation and are not suitable for installation as overhead or vertical glazing. The panels are considered to be in compliance with IEC 61215 /61730, only when the panel is mounted specified by the mounting instructions below. The junction box on the back of the panel is protected to IP67 and hence panels can be mounted in any orientation.
Clamps must be secured between a distance of 250 mm - 350 mm from the clamp centerline to the end of the panel. Tightening torque must be tightened to 21.7 Nm The distance between the end clamp and the end of the rail must be minimum 25 mm Fig. 5: Long side mounting 1” ” 9 7/8 13 3/4 In areas of snow build-up, panels can be subjected to forces in excess of the stated limit even when snow depth does not appear extreme, causing damage to the framework.
v) Slide-in Systems For installations using a slide-in mounting structure, specifications must match those of the clamps noted above regarding grip length and depth. If you have any questions regarding a mounting system and its suitability for REC Peak Energy 72 Series panels, please contact your local office for technical support. vi) Drainage holes There are eight drainage holes, 3/8 x 1/4 in (12 x 7.5 mm) in the panel frame, each spaced 2 1/8 in (55 mm) from the corner of the panel frame (fig. 9).
Maintenance Cleaning Instructions REC Peak Energy 72 Series 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.
