SAFETY MEASURES
Installers are responsible for the safe and effective installation and operation of the system and for adhering to all applicable local and national
standards and regulations. All relevant local codes and regulations should be referred to and observed.
SAFETY IN THE WORKING AREA
Installation of REC solar panels may involve working on rooops or raised platforms. Ensure all local regulations regarding working at heights and fall
protection are followed. Before beginning work on an installation, ensure all working surfaces are structurally sound and capable of bearing the weight
of employees and required equipment.
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.
Specific hazards of DC electricity
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 thefully insulatedplug contactson thepanel’soutputcables providetouch-safeprotection, the followingpointsmust 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
DANGER - Electrical shock
Solar panels generate direct current (DC). Once current is flowing, breaking 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, capable of high temperatures that
can destroy contacts and connectors:
• Isolate the system and remove/open the inverter AC fuse/circuit breaker from the grid before carrying out any maintenance or repair work.
• Follow inverter manufacturer’s installation, handling and operating instructions.
• High-voltage components need sufficient time to discharge.Wait for the time specified by the manufacturer before commencing work.
• 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.
REC Installation Manual - REC Alpha Series - UL 6
Rev C . Ref: NE
PANEL HANDLING
In order to avoid damage, all REC solar 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, carrying, installing or storing 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 or cables as a grip,
• Do not allow the panels to sag or bow under their own weight when being carried,
• Do not subject panels to loads or stresses, e.g., leaning on them or through the placing of weight on them,
• Do not stand or walk on the panels,
• Avoid dropping the panels as any damage caused may be unseen,
• Keep all electrical contacts clean and dry,
• 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 front or rear of the panel,
• Do not use any solar panel that is damaged or has been tampered with,
• Never aempt to disassemble, modify, or adapt the panels or labels in any way as this will void the warranty.
The pallet packaging is not water- or weatherproof. Prior to installation, and to avoid damage or degradation to the packaging or panel components,
palletsandpanelsmustbestoredinacontrolledenvironment,ideallyinternal,whereitisprotectedfromtheelements, e.g., rain,dust,anddirect sunlight.
If overnight storage in an uncontrolled environment is unavoidable, the panels and the pallet packaging must be protected from direct exposure to the
elements and from contact with the ground, including earth, mud etc.
CHOOSING AN INSTALLATION LOCATION
REC solar panels are designed to provide decades of durable and stable output in installations up to ( m) above sea level. Ambient
operating temperatures must be between -° - °F (-° 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 gas or vapor e.g., gas stations, gas containers or spray paint facilities,
• Near open flames,
• Near salt water/spray,
• Under water or in water features,
• Where exposed to sulfur e.g., near sulfur springs or volcanoes,
• Where exposed to artificially concentrated sunlight,
• Where the panels may be exposed to harmful chemicals.
NOTE
Use clean and protective gloves when handling the panel as this will avoid the transfer of any fingerprints or soiling to the highly-sensitive and anti-
reflective glass surface, ensuring improved light transmission and avoiding any contamination.

ELECTRICAL INSTALLATION
ELECTRICAL REQUIREMENTS
System Requirements
REC solar 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.
String configuration
When connecting panels in a string, plan and execute according to the inverter manufacturer’s instructions. The number of panels connected to an inverter
must not exceed the voltage limits and operating range permied by the manufacturer, nor under any circumstance exceed the maximum system voltage
as stated in the technical specifications for the product at the rear of this manual.The maximum system fuse rating (overcurrent protection rating) and the
maximum reverse current for each panel can be found in the technical specifications for the product at the rear of this manual.
The maximum number of panels in a string can be calculated by dividing the maximum system voltage of the panel by its VOC accounting for the lowest ambient
temperature at site, e.g.: for a V system, if the lowest ambient temperature is °C, the panel has a VOC of .V and a temperature coefficient of VOC of
-./°C, the maximum panels per string is (∆T°C = ° - ° = °; ° x . = .; . + . = .; V / . = ., so a total of panels or
V). Qualified system designers can make exact calculations that account for specific project requirements and site conditions.
String connection
If panels are connected in series, they must have the same ampere rating. If panels are connected in parallel, they must have the same voltage rating.
The maximum number of panels that can be connected in series or parallel depends upon system design, type of inverter and environmental conditions.
Panel and string configuration must correspond to the specifications of other system components e.g., inverter. Refer to the reverse current rating of
the panel as indicated in the technical characteristics section to the rear of this manual or on the panel datasheet.
Wiring
Wiring installation shall be in accordance with the National Electric Code (NEC) (or CSA C., Safety Standard for Electrical Installations, Canadian
ElectricalCode, Part where applicable).To minimizevoltagesurges(e.g., indirectlightning strikes),cables ofthe samestring mustbe bundledtogether
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.
Electrical Ratings
Electrical ratings are within a specific tolerance of measured values at Standard Test Conditions (STC) as given in the technical characteristics for each
panel at the rear of this manual. Under normal conditions, a photovoltaic panel is likely to experience conditions that produce more current and/or voltage
than reported at STC. The requirements of the NEC in Article must be followed to address these increased outputs. In installations not under the
requirements of the NEC, the values of ISC and VOC marked on the panels must be multiplied by a factor of . (or according to local regulations) when
determining component voltage ratings, conductor ampacities, overcurrent device ratings and size of controls connected to the PV output.
MECHANICAL INSTALLATION
FIRE GUIDELINES
REC Alpha panels have a Type fire rating according to UL. The fire performance rating of the panels is only valid when mounted in the manner
specified in this installation manual. The complete system fire class rating is to be achieved by the combination of panel fire performance type and
UL certified mounting structure for a non-BIPV panel. Please refer to mounting structure UL listing for System Fire Classification. Any
specific limitations on the inclination or accessories required to maintain a specific System Fire Class Rating must be clearly specified in the mounting
system manufacturer’s installation instructions and UL certification. Utilize the following fire safety guidelines when installing REC panels:
• Check with all relevant local authorities for fire safety 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 relevant 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 be mounted over a fire retardant roof covering rated for the application and a distance of at
least . in mmbetween the panel and the mounting surface, to allow the free circulation of air beneath the panels at all times.
ORIENTATION
The optimal mounting position of a panel results in the sun’s rays falling perpendicular (i.e., at °) to the surface. To maximize system output, panels
shouldbeinstalledattheoptimumorientationandtiltangle.Thespecificsofthisdependonlocationandcanbecalculatedbyaqualifiedsystemdesigner.
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. Dependent on local conditions, a lower angle of installation will potentially increase the requirement for regular cleaning.
DANGER - Electrical shock
Safety is paramount when working on the electrical installation. Always follow the electrical requirements to avoid the risk of sparking, fire hazards,
burns and lethal electric shocks.
REC Installation Manual - REC Alpha Series - UL 6
Rev C . Ref: NE
PANEL INSTALLATION
REC solar panels are designed for capturing solar radiation and are not suitable for use as overhead or vertical glazing. The IP rating of the junction box
provides a level of protection that allows panels to be mounted in any orientation. There are different options for securing REC solar panels depending
on the design of the array. Mounting hardware is not supplied by REC. Ensure the mounting structure can withstand anticipated wind and snow loads.
Follow the mounting hardware manufacturer’s instructions and recommendations at all times.
Installing the REC Alpha Series solar panels with clamps and rails has been found to comply with UL & UL requirements for downward
pressure,e.g.,snow,ofuptopsf(PaorPadesignload*)andupwardpressure,e.g.,wind,ofupto.psf(PaorPadesignload*)according
tothe instructionsbelow(*design loadsapply asafetyfactorof .to thestated testload,e.g., testload Pa/ .= Pa designload).Site-specific factors
suchas highwinds orsnowlevelsmust betakeninto consideration toensure thislimit isnot exceeded.
RAIL SPECIFICATIONS
When installing on mounting rails, ensure they run underneath the panel and provide support to the frame.The positioning of the rail must ensure
that the minimum clamp grip length and the central point of the fixation, e.g., the bolt, is fully within the required clamping zone as indicated on the
following pages.
CLAMP SPECIFICATIONS
Clamp installation must be carried out according to the manufacturer’s instructions, including specific hardware and torque requirements.

DRAINAGE HOLES
In each corner of the REC frame small drainage holes are spaced . in ( mm) from the corner on long and short sides (fig. ). These allow humidity
caused by rain, condensation, snow melt, cleaning or any other process to exit the frame easily and minimize damage.These holes must not be used for
mounting the panel, and they must not be covered by any part of the mounting structure. To enable effective drainage and ensure there is no damage to
the panel, the drainage holes must remain fully open and enable water egress during and aer installation. Theshape anddimensions of thedrainageholes
may vary depending on product and/or frame design.
GROUNDING
A panel with exposed conductive parts is considered to be in compliance with UL & UL only when it is electrically grounded in accordance
with the instructions presented below and the requirements of the National Electrical Code.When grounding a panel, it must be done using an electrical
connection from the panel frame. Local regulations may require grounding of the panels. Grounding must be done using an electrical connection from
the panel frame. REC solar panels have a small round grounding hole positioned near each corner of the panel on both the long side and the short side, as
shownin fig. andcan be further identified by the grounding symbol stamped in the frame next to it. Check all applicable requirements before beginning
installation:
• Suitable grounding lugs must be used: Listed (KDER) ILSCO, GBL-DBT(tin plated) (E),
• Grounding cable size should be between AWG (. mm - . mm),
• Aach 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,
• Follow the grounding device manufacturer’s installation instructions to ensure a safe and conductive connection, including any supplementary
hardware, e.g., star washer, and tighten according to recommended torque.

To ensure connector compatibility and reduce the potential for damage to the panels and the wider installation, the connectors used on the REC Alpha Series
are detailed in the Panel Characteristics at the rear of this manual. REC only permits the mating of factory-installed connectors to connectors of the same
manufacturer, type, and system rating as shown in the table below (fig. ):
Fig. : Connector mating matrix
Connector 1 +Connector 2 Permied?
REC Factory-Installed + REC Factory-Installed
REC Factory-Installed + Stäubli MC
REC Factory-Installed + Any other connector
CUTTING THE CABLES
The cuing of cables is only permied in order to replace a factory-installed connector with another brand of connector to ensure ‘like-for-like’ mating when
connected to a non-REC external device. All other changes are prohibited and will invalidate the REC warranty.
• The connector replacement procedure must be carried out correctly and according to the replacement connector manufacturer’s instructions.
• Theselectedreplacementconnectormustalsofulfil allrelevanttechnicalspecificationsand becertifiedaccordingtoapplicablestandards(e.g.,EN,
IEC or UL ) to ensure they are fit for purpose and safety.
• Use of any chemicals or lubricants on the connectors or contacts may only be carried out in line with the connector manufacturer’s instructions.
TheRECwarrantydoesnotextendtocoveranyfaulttraceabletothereplacedconnectors.Anyothermodificationtothepanelisprohibited,includingtheopening
of the junction box, unless explicitly authorized by REC. Doing so will invalidate the warranty.
CABLE MANAGEMENT
To ensure a long life span of the cables and reduce the potential for damage to the cables, follow the instructions below:
• 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 must have a minimum bending radius of . in ( 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 mechanical abrasion or grazing animals,
• Protect 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 using UV-resistant cables,
• When securing the connector, place it so that it has with sufficient air circulation all around.This allows the connector to dry effectively and avoids the risk
of damage or degradation of the connection,
• Secure the cable either side of the connectors to ensure 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.
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)
NOTE
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.
i
DANGER - Electrical shock
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.

PANEL MAINTENANCE
CLEANING INSTRUCTIONS
REC solar panels have been designed for easy maintenance. However cleaning solar panels can assist in optimizing electricity output. The need for
cleaning will vary dependent on location, rainfall, pollution levels and the angle of installation – the lower the angle of installation, the more cleaning will
be required. ‘Normal’ rainfall will naturally clean the panels if installed at a sufficient angle to ensure water runs off the surface. To optimize electrical
output it is recommended to clean the panels when dirt can clearly be seen on the glass surface.
Using a so rubber squeegee, wipe the panel surface from the top downwards to remove any residual water from the panel glass. Take care not to
scratch the surface or introduce foreign elements that may cause damage to the panel. Always rinse the panel with plenty of water. Panels can be le to
dry in the air or wiped dry with a clean and so cloth or chamois.
For more information on cleaning REC solar panels, consult the
REC Cleaning Information Sheet
which is available to download from the online REC
Download Center www.recgroup.com/downloads. If in doubt at any time when cleaning the panels, stop and obtain professional advice.
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 makes 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 packaging and panels according to local guidelines and regulations.
DISPOSAL OF OLD ELECTRICAL AND ELECTRONIC EQUIPMENT
Panelsshouldberecycledattheendoftheirusefullifeaccordingtolocalguidelinesandregulations. ByensuringRECsolarpanels are disposed of correctly,
you will help prevent potential negative consequences for the environment and human health which could otherwise be caused by inappropriate waste
treatment. The majority of the panel components can be recycled.
CAUTION
• Panel cleaning must always be carried out when the panels are cool, e.g., early morning, to avoid breakage through thermal shock.
• Use of high pressure hoses or cleaners is not permied as these may damage the panels, laminate or cells.
NOTE
• Avoid puing pressure on the on the panel surface when cleaning or drying, e.g., leaning, standing or resting buckets on it.
• Use only deionized water free from grit and physical contaminants, at ambient temperature and use 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.
• If stains require more effort to be removed, Isopropyl alcohol of a concentration less than may be used. Acidic or alkaline detergent may not
be used.

includetesting on thesetypes of systems).When installingany of theabovenamed RECsolar panels onfixedposition (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.
INSTALLATION ENVIRONMENT
i) Installation site
• REC solar panels may only be installed on closed bodies of fresh water where water salinity does not exceed PSU ( mS/cm) at °F (°C).This
specifically excludes mounting on sea and ocean applications.
• The maximum permied 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 solar panels on floating platform systems is 6 in ( 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 INSTRUCTIONS
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.
ii) Mounting panels
• Installation of REC solar panels must be in accordance with the aforementioned standard mounting instructions.
• Thejunctionboxshouldbeorientedasfaraspossiblefromthewatersurfaceaccordingtosystemdesignandthejunctionbox,cablesandconnectors
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, e.g.,
shading or to the local environment etc.
• 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.
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 aempt to salvage panels
when sunlight is present.

ANNEX : INSTALLATIONS USING MODULE LEVEL POWER ELECTRONICS
This section is applicable to all REC products referred to in this installation manual.
ModuleLevelPower Electronics (MLPE)is the name givento therangeof panel-levelcomponents that can be installedin PVsystemcircuits installedon
or in buildings to reduce shock hazard for emergency responders. MLPE devices can be supplied pre-installed by panel manufacturers or as a ‘retro-fit’
system made by third-party manufacturers. From January , , Section . of the National Electrical Code (NEC) (in the U.S.A.) requires
thepanel-levelrapidshutdownofsolarsystems (replacing thepreviousarray-level shutdown requirement ofNEC).This meansthatall conductors
within an array’s . in ( mm) boundary have to be reduced to V or less within seconds of rapid shutdown initiation.
MLPE devices may be used on REC solar panels where desirable or mandatory (note that the certification testing of solar panels does not include
testing with MLPE devices).When installing an MLPE device on an REC solar panel, follow the instructions provided by the device manufacturer and the
instructions specific for REC solar panels given below. Failure to follow the manufacturer and the REC instructions may invalidate the warranty.
INSTALLATION
i) Installation
• MLPEdevices aresuitable foruse whereversolar panelsare suitable for installation. Observeany limitations set bythe MLPE manufacturer. (e.g.,
minimum mounting gap between MLPE and rooop).
• When aaching an MLPE device to a solar panel, it must be secured to the panel frame. Follow MLPE manufacturer instructions to ensure
optimum mounting of MLPE device and prevent any slippage during operation.
• MLPE devices may also be aached to the mounting construction. In such cases, refer to the instructions provided by the manufacturer.
• Wherever possible, the installation of the MLPE device should not cover the product label on the rear of the panel.
• MLPE devices may only be installed on REC solar panels in the areas shown in the diagram below (fig. ):
Fig. :MLPE device installation zones
Installation of MLPE device in the green zone is permied.
Installation of MLPE device in the red zone is not permied.
CAUTION
• To avoid damage to the panel and to allow for thermal expansion, there must be a minimum gap of . in (. mm) between the MLPE device and
the panel backsheet.
• The mounting holes in the panel frame must not be used for the installation of MLPE devices.
• The drilling of extra holes in the frame is not permied and will invalidate the panel warranty.
CONNECTION
• First ensure the installation of the MLPE device is secure and safe.
• Following the device manufacturer’s instructions to connect the cables from the MLPE device to the solar panel correctly (usually positive to
positive [+ to +] and negative to negative [- to -]).
• Connection to the next panel in the array should be done from the ‘free’ cables.
SAFETY
• Immediately disconnect the device if there is a problem during installation.
