ELECTRICAL INSTALLATION
ELECTRICAL REQUIREMENTS
i) Application Class
REC Peak Energy  panels are rated for use in electrical application class A: Hazardous voltage (IEC : higher than VDC; 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 Peak Energy  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
invertermustbe withintheinvertervoltagelimits and operating range. Do notexceed thetotal system voltage permied by the manufacturer,
nor under any circumstance exceed the maximum system voltage of the panels (Vfor the REC Peak Energy  Series and  Vfor REC
Peak Energy  XVSeriespanels). 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 section to the rear of this manual 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 must be observed at all times.
vi) Electrical Ratings
Electrical ratings are within  of measured values at StandardTest Conditions (STC). Allow for increased panel output as a result of conditions
different to STC by multiplying the ISC and VOC values by a factor of . (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.
• Exercise 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., non-slip 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.

PANEL HANDLING
All solar panels should be handled with care. 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 avoid using 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. Do not stand on them or drop them.
• 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 the panels.
If the panel front glass is broken or laminate back sheet is damaged, it can expose personnel to hazardous voltages.
MECHANICAL INSTALLATION
FIRE GUIDELINES
REC Peak Energy  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. Utilize the following fire safety guidelines when installing REC Peak Energy  panels:
• Check with relevant local authorities for fire safety guidelines and requirements for any building or structure on to which the panels will
be installed
• Check with local authorities for fire safety guidelines and requirements relevant to where the panels will be installed.
• The system design should ensure that it can be easily accessed in the event of a fire.
• Check with relevant local authorities for applicable regulations concerning setbacks or other restrictions that may apply for ground-
mounted arrays.
• The use of DC ground fault interrupters is recommended. Check whether this is also required by local and national codes.
• All electrical appliances are a fire risk. The panel must therefore be installed with a suitable distance of  mm between the panel and
the closest surface. This allows the free circulation of air beneath the panels.
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. A lower angle of panel installation increases 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 sunlight.
ENVIRONMENTAL FACTORS
REC Peak Energy  panels are designed to provide decades of durable and stable output. Operating temperatures should be between °C
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 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.

MOUNTINGTHE PANELS
REC Peak Energy  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  /, only when the panel is mounted specified by the mounting instructions
below. The junction box on the back of the panel is protected to IP and hence panels can be mounted in any orientation.
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.
PANEL INSTALLATION
REC Peak Energy  panels are typically installed on a rail-based mounting system. There are two different methods of installing an REC Peak
Energy  panel, as decribed below (fig a & b), depending on the design of the array. The rails can run under the frame or parallel to the frame,
directly under the indicated clamping zones. Ensure the mounting structure is able to withstand anticipated wind and snow loads. Mounting
hardware is not supplied by REC. Follow the mounting hardware manufacturer’s instructions and recommendations at all times.

REC Peak Energy  panels have been certified for mounting using rails in combination with end and mid clamps, ASTM FC stainless steel
screw and rail nuts with the below ratings and dimensions. Ensure the clamps are suitable for the planned installation and expected system
design loads (fig. ):
(a) Long side mounting
Ensuring sufficient airflow and adequate cooling of the panels can help improve performance. There must be a minimum distance
of 100 mm between the uppermost part of the roof and the lowest part of the panel to dissipate heat produced.
Fig. : An array mounting system with each panel secured at
four points.
• The panel must be clamped in a minimum of four points clamps per panel (two per clamped side) (fig ).
• Minimum grip length of  mm, minimum grip depth of  mm (fig. ). The grip must not overlap the panel frame and cause shading.
• Use appropriate bolted connections as per clamp manufacturer’s instructions.
• Follow the clamp manufacturer’s recommended applied torque to fasten the clamps.
Each panel must be securely fixed to the mounting structure at a minimum of four points (fig. 4).
(b) Mounting holes
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.

CONNECTIONS AND CONNECTORS
Theconnectors onREC PeakEnergy panels are rated IP onlywhen connected. All connectorsand cables mustbe secureandtight aswell
aselectrically andmechanicallysound. UV-resistant cablesandconnectors approvedforoutdoor use mustbe used. Conductor gaugemustbe
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.
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 online Download Center (www.recgroup.com/downloads).
Safety is paramount when working with electrical connectors. Ensure that any installation work is not carried out on live or load-carrying
parts. Connections must not be disconnected under load and the system must be isolated from the grid before carrying out any maintenance
or repair work.
CONNECTORS
To ensure connector compatibility and reduce the potential for damage to the solar modules and wider installation, REC recommends that
mated connectors are from the same manufacturer and of the same connector type. REC factory installed connectors are of the ‘MC type’
design. This means that REC only permits the mating of factory-installed connectors to connectors of the same manufacturer and type and to
Multi-Contact MC connectors.
Some countries and/or regions have specific regulations regarding the mating of connectors. Installers are responsible for ensuring
the compliancy of the system with such local regulations.
REC factory installed connectors are of the ‘MC4 type’ design. This means that REC only permits the mating of factory-installed
connectors to connectors of the same manufacturer and type and to Multi-Contact MC4 connectors.
Excepting the replacement of a factory-installed connector with a third brand of connector to ensure a ‘like-for-like’ connection,
the REC warranty will be voided by any modification to the cable and/or connector. The connector replacement procedure must be
carried out correctly and according to the replacement connector manufacturer’s instructions. The selected third-brand connectors
must also fulfil all relevant technical specifications and be certified according to applicable standards (e.g., IEC 50521 and
IEC62852)soastoensuretheyarefitforpurposeandsafety. TheRECwarrantydoesnotextendtocoverthe replacement connectors.
• The secure connection of connectors is identified by a firm click once inserted.
• The use of any chemicals or lubricants on the connectors or contacts must be carried out in line with the connector manufacturer’s instructions.
Any other modification to the panel is prohibited, including the opening of the junction box, unless explicitly authorized by REC.
Doing so will invalidate the warranty.
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 REC Peak Energy  panels 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 over-tightening, as this can deform the cable insulation.
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.
Panel cleaning should be carried out in the early morning when the panels are cool to avoid thermal shock.
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 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). Use a telescopic handle to extend reach. 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, Isopropyl alcohol of a concentration less than  may be
used. Acid or Alkali detergent may not be used.
Use of high pressure hoses or cleaners is not permied as these may damage the panels, laminate or cells.
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 Peak Energy  solar panels, consult the Cleaning Information Sheet available to download from the
online REC website at www.recgroup.com/download.
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).

ANNEX . INSTALLATIONS ON WATER PLATFORMS
RECPeakEnergySeriespanels may be installedonwaterplatform-typemountingsystems (note thatthecertificationtestingofsolarpanels
doesnot include testingonthesetypes of systems). WheninstallingRECPeakEnergy  panelsonfixedposition,oranchored, waterplatforms,
for example, floating pontoons, follow the instructions below specific to such applications. Failure to do so will invalidate the warranty.
For all installations on water platforms, first advise REC before the start of installation in case of any site specific instructions or
constraints
INSTALLATION ENVIRONMENT
i) Installation site
• REC panels may only be installed on closed bodies of fresh water where water salinity does not exceed  mS/cm at °C ( PSU). This
specifically excludes mounting on sea and ocean applications.
• The maximum permied wave height must not exceed  m from the crest to the trough of the wave.
ii) Floating platforms
• When using a floating platform, follow the manufacturer’s instructions regarding installation, maintenance, inspection and cleaning at all times.
iii) Minimum installation height
• The minimum installation height of REC Peak Energy 72 panels is  cm and is defined as the height between the water surface and the
lowest edge/part of the panel during normal operation. This will help to shield the panel from direct water spray.
INSTALLATION INSTRUCTION
i) System installation
• All cables used for the installation must have sufficient length and slack to prevent damage due to water level changes and wave motions.
Negative system grounding is required for REC Peak Energy 72 panels installed on a floating platform
ii) Mounting panels
• Installation of REC Peak Energy 72 panels must be in accordance with the aforementioned standard mounting instructions.
• The junction box should be oriented as far as possible from the water surface according to system design and the junction box, cables
and connectors must be protected from direct water splash.
• The installation must allow for sufficient spacing between individual panels, in order to avoid all contact as caused by the natural
movement and flexing of the floating structure.
iii) Panel protection
• In areas with high avian activity, additional bird repelling devices may be installed as long as they do not adversely affect system performance.
• If using lightning protection equipment on the floating installation, all relevant local regulations must be respected.
MAINTENANCE
• Regularly inspect the installation to ensure all panels are securely mounted.
For installations with high avian activity, system cleaning may be required at more frequent intervals to reduce shading of panels
caused by bird defecation
SAFETY
• Immediately disconnect the system if the installation or the floating platform exhibits deviation from standard operating conditions.
• In the event of the floating platform being submerged, disconnect the DC connection at the inverter immediately. Do not aempt to
salvage panels when sunlight is present.
