ELECTRICAL INSTALLATION
ELECTRICAL REQUIREMENTS
i) Application Class
REC panels are rated for use in electrical application class A: Hazardous voltage (IEC : higher than V DC; EN : higher than
V), hazardous power applications (higher than W) where general contact access is anticipated (panels qualified for safety through
EN IEC - and - within this application class are considered to meet the requirements for Safety Class II).
ii) System Requirements
REC panels are only for use where they meet the specific technical requirements of the complete system. Ensure other components will not
cause mechanical or electrical damage to the panels. Only panels of the same type and power class should be connected.
iii) String configuration
When using string configuration, plan and execute it according to inverter manufacturer’s instructions. The number of panels connected
to an inverter must be within the inverter voltage limits and operating range. Do not exceed the total system voltage permied by the
manufacturer, nor under any circumstance exceed the maximum system voltage of V. The maximum system fuse rating is A, the
maximum reverse current is A.
iv) String connection
Panels connected in series must have the same amp rating. The maximum number of panels that can be connected in series depends upon
system design, type of inverter and environmental conditions. There are no restrictions on the number of panels that may be connected in
parallel. Panel configuration must correspond to the specifications of other system components e.g. inverter. Refer to the reverse current
rating of the panel (indicated in theTechnical Characteristics on p.  or on the panel datasheet).
v) Wiring layout
To minimize voltage surges (e.g. indirect lightning strikes), cables of the same string must be bundled together so loops are as small as
possible. String configurations must be checked before commissioning. If open circuit voltage (Voc) and short circuit current (Isc) deviate
from specification, this may indicate a configuration fault. Correct DC polarity is to be observed at all times.
vi) Junction box, cables, connectors
The junction box on REC Peak Energy panels is rated IP. 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 (<).
Observe all local regulations when selecting cables. For string connections, use minimum  mmor copper wires insulated for a maximum
operating temperature of °C. Secure cables using UV-resistant cable ties or other device. Loose and unsecured cables must be protected
from damage (e.g., mechanical, abrasion, sharp objects, animals). Avoid exposing cables to direct sunlight and permanent tension.
REC prohibits any modification to the panel, including the cuing of cables in order to change the connector type or the opening
of the junction box unless explicitly authorized by REC. Doing so will invalidate the warranty.
vii) Electrical Ratings
Electrical ratings are within  of measured values at StandardTest Conditions (STC). Allow for increased output of a panel as a result of
conditions different to STC by multiplying the values of ISC and VOC by . (or according to local regulations for electrical system installation).
SAFETY MEASURES
All relevant codes and regulations should be referred to and observed as well as regulations on working at heights and fall protection.
i) Safety in the working area
Installation of REC Peak Energy panels may involve rooop work. Ensure all local regulations regarding working at heights are followed.
Before beginning work on a photovoltaic system, ensure all working surfaces are structurally sound and capable of bearing the weight of
employees and required equipment. Remember to isolate the system from the grid before carrying out any maintenance or repair work.
ii) Preventing current generation
To prevent the panels automatically generating current (electricity) when exposed to light, shield the system with a non-transparent cover
during installation, maintenance or repair work.
iii) Specific hazards of DC electricity
Solar panels generate direct current (DC). Once current is flowing, breaking or opening a connection (e.g. disconnecting two panels) can
cause an electrical arc. Unlike low voltage AC wiring, DC arcs are not self-extinguishing. They are potentially lethal burn and fire hazards:
• Follow panel and inverter manufacturers’ installation, handling and operating instructions.
• Remove/open the inverter AC fuse/circuit breaker before disconnecting from the public grid.
• Switch off or disconnect the inverter and wait for the time specified by the manufacturer before commencing work. High-voltage
components need sufficient time to discharge.
iv) Safety requirements
The voltage produced by a single panel and panels connected in series (voltages added together) or in parallel (currents added together) can
be dangerous. Although the fully insulated plug contacts on the panel’s output cables provide touch-safe protection, the following points
must be observed during handling to avoid the risk of sparking, fire hazards, burns and lethal electric shocks.
• Excercise extreme caution when wiring panels and look out for damaged or dirty cables etc.
• Never insert metallic or other conductive objects into plugs or sockets.
• Ensure that all electrical connections are completely dry before assembly.
• Keep all materials, tools and working conditions dry and tidy.
• Use appropriate safety equipment e.g. nonslip footwear, insulated gloves and insulated tools.
• Solar panels produce current when exposed to sunlight. Do not connect the system to the inverter during solar exposure.

MECHANICAL INSTALLATION
FIRE GUIDELINES
REC Peak Energy Series panels have a Class C 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 must ensure that it can be easily accessed in the event of a building fire.
• Check with local authorities for applicable regulations concerning setbacks or other placement restrictions that may apply for roof-
mounted arrays.
• The use of DC ground fault interrupters is recommended. This may also be required by local and national codes.
• All electrical appliances are a fire risk. The panel must therefore be mounted over a fire retardant roof covering rated for the application
and a distance of  mm between the panel and the mounting surface, allowing free circulation of air beneath the panels must be
respected at all times.
ORIENTATION
To maximize system output, panels should be installed at the optimum orientation and tilt angle. The specifics of this depend on location and
can be calculated by a qualified system designer.
Dependent on local conditions, a lower angle of installation will potentially increase the requirement for regular cleaning.
The optimal mounting position of panels results in the sun’s rays falling perpendicular (i.e. at °) to the surface. All panels in a string should,
wherever possible, have the same orientation and tilt to ensure the system does not underperform due to mismatched outputs.
The panels should not be exposed to artificially concentrated light.
ENVIRONMENTAL FACTORS
REC Peak Energy Series panels are designed to provide decades of durable and stable output. Operating temperatures must be between
 and +°C.
The panels are not suitable for installation in potentially hazardous locations nor should they be installed in the following locations:
• Near sources of flammable gases or vapors e.g. gas stations, gas containers or spray paint facilities.
• Near open flames.
• Under water or in water features.
• Where exposed to sulfur e.g. near sulfur springs or volcanoes.
• Where the panels may be exposed to harmful chemicals.
Ensure panels are not exposed to direct contact with salt water/spray and avoid installation in areas subject to high salt mist
content.
PANEL HANDLING
Panels should be handled with care and protected from damage at all times. All warnings and instructions on the packaging should be
observed. Follow these guidelines when unpacking, transporting or storing the panels:
• Record the serial numbers prior to installation and note the information in the system documentation.
• Carry the panels using both hands and do not use the junction box as a grip.
• Do not allow the panels to sag or bow under their own weight when being carried.
• Do not subject the panels to loads or stresses, e.g., leaning on them or through the placing of weight on them.
• Do not stand on the panels.
• Avoid dropping the panels as any damage caused may be unseen.
• Keep all electrical contacts clean and dry.
• Store panels in a dry and properly ventilated room.
• Do not apply force to the backsheet.
• Avoid using sharp or pointed objects if panels require marking.
• Never apply paints, adhesives or detergents to the back of the laminate.
• Do not use any solar panel that is damaged or been tampered with.
• Never aempt to disassemble, modify or adapt the panels or labels in any way as this will void the warranty.
Do not use a panel which is broken or damaged. If the panel front glass is broken or laminate back sheet is damaged, it can
expose personnel to hazardous voltages.

MOUNTINGTHE PANELS
REC Peak Energy Series 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 IP 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.
There are different options for securing an REC Peak Energy Series panel, depending on the design load of the array. Ensure the mounting
structure design can withstand anticipated wind and snow loads. Mounting hardware is not supplied by REC. Follow manufacturer’s
instructions and recommendations at all times.
Ensuring sufficient airflow and adequate cooling of the panels can help improve performance. There must be a minimum distance
of  mm between the uppermost part of the roof and the lowest part of the panel.
i) Rail specifications
REC Peak Energy panels are typically installed on a rail-based mounting system. If using mounting rails, ensure they run under the frame or
parallel to the frame (fig ), directly under the clamping zones (fig ).
The overlap between the support rail and the outer edge of the frame must be a minimum of  mm.
ii) Clamp specification
Ensure the clamps used are suitable for the planned installation and expected system design loads.
Fig. : Panels secured at four points.
Remove any labels or stickers that may be on the front of the panels (where applicable) and ensure no residue is le on the glass.

• The panel must be clamped by a minimum of two clamps per side (four clamping points per panel) (fig ).
• Minimum grip length of  mm, minimum grip depth of  mm (fig. ). The grip must not overlap the panel frame and cause shading.
• Use approproate bolted connections as per clamp manufacturer’s instructions.
• Follow the clamp manufacturer’s recommended applied torque to fasten the clamps.
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. If the installation is likely to be affected by this, further suitable panel support is
recommended on the lower row of panels.

The panels can also be secured to the mounting structure using the mounting holes (fig. ) found on the underside of the frame (. x 
mm, spaced  mm from the midpoint of the long side). Bolts of size  mm secured with  mm locking nuts with a flange should be used to
secure the frame to the mounting structure (fig. ). Observe the following procedures when using mounting holes:
• The mounting construction should be of aluminium or galvanized steel to avoid galvanic corrosion and be appropriate for the local
environment.
• Additional electrical bonding to Ground is required for the support structure (see Grounding).
• All four mounting holes in the frame must be used.
• Tighten fastenings using a torque wrench according to the understructure manufacturer’s instructions.
The product warranty will be voided if additional holes are made in the frame. All fixing and fastening materials must be
corrosion resistant.
v) Slide-in Systems
REC Peak Energy panels may also be installed using slide-in systems. Such mounting systems must meet the same specifications regarding
grip lengths and depths as clamps and be able to withstand the correct load pressures. When installing with slide-in systems, the drainage
holes (fig. ) must not be covered. For any questions regarding installation on such systems, please contact REC directly.

vii) Grounding
Local regulations may require grounding of the panels. Check all applicable requirements before beginning installation. Where grounding is
necessary, it must be done using an electrical connection from the panel frame:
• Suitable grounding lugs must be used.
• Grounding cable size should be between . mm - . mm.
• Aach grounds to the grounding holes in the panel frames.
• Fix lug to the frame using a star washer and lock nut, ensuring a conductive connection (fig. ).
• Place the star washer between the frame and the nut, using a  mm diameter stainless steel bolt and locking nut to mount the lug to the
panel frame and tighten according to the manufacturer’s recommended torque.
To avoid galvanic corrosion, stainless steel fastening materials are preferred, however galvanized or hot dipped zinc plated
fasteners are equally suitable.
CONNECTIONS AND CONNECTORS
In order to ensure durable and safe connections between panels and BOS equipment, the following instructions must be followed in order
to protect the electrical connections from the elements. More detailed information is given in the Guide to Best Practice - Connections and
Connectors which can be found via the REC website Download Center (www.recgroup.com/downloads).
CONNECTORS
• Connectors must be securely joined to each other according to the manufacturer’s instructions. REC explicitly excludes the cuing of
cables and replacement of connectors. If this causes an issue for a particular site, contact REC via www.recgroup.com for further advice
• The use of any chemicals or lubricants on the connectors or contacts must be carried out in line with the connector manufacturer’s
instructions
PROTECTING THE CABLES
• To prevent stress on the junction box casing, ensure the cable exits the junction box in a straight line before any bend in the cable.
• The cables on the REC Peak Energy Series have a minimum bending radius of  mm to avoid damage to the insulation (Fig. )
• Ensure cables do not hang loose where they may be damaged through friction or stress, e.g., caused by wind or grazing animals
• Shield connectors from falling or dropping water by locating them directly beneath a panel
• Cables must be firmly secured to the structure, without overtightening, as this can deform the cable insulation
Ensure the drainage holes are not covered by the mounting structure.
vi) Drainage holes
Each corner of the panel frame has small drainage holes (fig. ) 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.

SECURING CABLES AND CONNECTORS
• When securing the connector, place it away from the mounting structure with sufficient air circulation all around. This allows the
connector to dry effectively and avoids the risk of damage or degradation of the connection
• Good practice is to secure the cable either side of the connectors, ensuring no stress is exerted on the connector casing or cable entry
To enable correct cooling and drying of the connectors, do not add extra protection to the connector, e.g., heat shrink, grease or
tape

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.
If dirt remains on the panel, it may cause cell shading which will reduce power output or even cause further damage. To clean either the front
or rear of the panels, use only deionized water at ambient temperature and a sponge, microfiber cloth or a so brush to wipe away the dirt
(rainwater, tap water or diluted alcohol may also be used as a secondary solution). For further cleaning a mild, biological and biodegradable
washing-up liquid may be used.
When cleaning the panel, take care not to scratch the surface or introduce foreign elements that may cause damage. Ensure the water used
is free from grit and physical contaminants that may damage the panel. Always rinse the panel with plenty of water. If soiling remains on the
panel, repeat the cleaning process. If stains require more effort to be removed, Iso-propyl alcohol of a concentration less than  may be
used. Acid or Alkali detergent may not be used
Cleaning of the panels should be carried out in the early morning when the panels are cool to avoid thermal shock.
Using a rubber squeegee, wipe the panel surface from the top downwards motion to remove any residual water from the panel glass. Panels
can be le to dry in the air or wiped dry with a chamois. Avoid puing pressure on the panel surface when drying.
For more information on cleaning REC panels, consult the Cleaning Information Sheet available to download from the online REC Download
Center www.recgroup.com/downloads.
SYSTEM INSPECTION
The system should be inspected regularly to ensure that:
• Fasteners are secure, tight and free from corrosion.
• Electrical connections are secure, tight, clean, and free of corrosion.
• The mechanical integrity of the cables is intact.
• Bonding points to ground are tight, secure and free from corrosion (which could break the continuity between the panels and ground).
RECYCLING
REC has made every effort to ensure panel packaging is kept to a minimum. The paper and cardboard packaging can be recycled and the
protective wrapping and panel separating blocks are also recyclable in many areas. Recycle according to local guidelines and regulations.
DISPOSAL OF OLD ELECTRICAL AND ELECTRONIC EQUIPMENT APPLICABLE TO E.U. COUNTRIES ONLY
