INTRODUCTION Thank you for choosing REC photovoltaic panels. REC Peak Energy 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) System Requirements REC panels are only for use where they meet the specific technical requirements of the complete system. Ensure other components do not cause mechanical or electrical damage to the panels. ii) Connection If panels are connected in series, they should have the same amp rating. If panels are connected in parallel, they should have the same voltage rating.
MECHANICAL INSTALLATION FIRE GUIDELINES REC Peak Energy Series panels have a Class C, Type 1 Fire classification. Utilize the following fire safety guidelines when installing REC Peak Energy Series 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 should ensure that it can be easily accessed in the event of a building fire.
MOUNTING the panels REC Peak Energy 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 UL 1703, only when the panel is mounted specified by the mounting instructions below. The REC junction box on the back of the panel is protected to IP67 and hence panels can be mounted in any orientation.
iii) Mounting holes Mounting utilizing the four elongated holes (0.26 x 0.43 in (6.6 x 11 mm)) on the underside of the panel frame (at a distance of 17.72 in (450 mm) from the midpoint of the long side) have been found to comply with UL 1703 requirements for a maximum design load of 75.2 lbs/ft² (3600 Pa) (fig. 5). When mounting using mounting holes, the frame and panel edge must be supported by two transverse rails (fig.
vi) Long side mounting using clamps Mounting utilizing clamps on the two long sides of the panel have been found to be in compliance with UL 1703 requirements for a maximum design load of 75.2 lbs/ft² (3600 Pa) (fig. 8). • Clamps must be secured between a distance of 8.2 in to 16.4 in (208 mm - 416 mm) from the corner of the panel (measured from the mid-point) to the clamp edge. • Tightening torque must be tightened to 9 ft-lbs (12 Nm).
Maintenance Cleaning Instructions REC Peak Energy 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.
