ELECTRICAL INSTALLATION
ELECTRICAL REQUIREMENTS
i) System Requirements
RECTwinPeak 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.
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
should 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 reverse current is  A and the maximum series fuse rating is  A.
iv) Wiring layout
To minimize voltage surges (e.g. indirect lightning strikes), cables of the same string should 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 should be observed at all times.
v) Junction box, connectors and materials
The panel junction box is rated IP, the connectors are rated IP only when correctly connected. All connectors and cables must be secure and
tight as well as electrically and mechanically sound. UV-resistant cables and connectors approved for outside use must be used. Conductor gauge
must ensure DC power losses (voltage drop) are kept to a minimum (< ). Observe all local regulations when selecting cables. For field connections,
use minimum AWG ( mm) or copper wires insulated for a maximum operating temperature of °C.
vi) Cable Management
Cables must be secured using UV-resistant cable ties or other sunlight-resistant device. Loose and unsecured cables should be protected from
damage (e.g. mechanical, abrasion, sharp objects, animals). As far as possible, 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
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 National Electric Code (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 . when determining component voltage
ratings, conductor ampacities, overcurrent device ratings and size of controls connected to the PVoutput.
SAFETY MEASURES
Wiring installation shall be in accordance with the NEC (or CSA C., Safety Standard for Electrical Installations, Canadian Electrical Code, Part 
where applicable). All relevant electrical installation codes and regulations should be observed for regulations on working at heights and fall protection.
i) Safety in the working area
Installation of RECTwinPeak panels may involve working on a roof. 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
Solar panels automatically generate current (electricity) when exposed to light. To prevent this, shield the system with a non-transparent cover during
installation, maintenance or repair work.
ii) Specific hazards of DC electricity
Solar panels generate direct current (DC). Once current is flowing, breaking or opening a connection (e.g. removing a DC cable from the inverter) 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:
• 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. 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.

PANEL HANDLING
To avoid damage to the solar cells and other components, 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 e.g., leaning or placing heavy objects on them.
• Do not stand on the panels or cause impact through dropping 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
RECTwinPeak panels have a Class C,Type  Fire classification. 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 RECTwinPeak 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.
• 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 should therefore be mounted over a fire retardant roof covering rated for the application and
a suitable distance of  in ( mm) between the panel and the mounting surface, allowing free circulation of air beneath the panels, should 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. 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 must not be exposed to artificially concentrated sunlight.
ENVIRONMENTAL FACTORS
RECTwinPeak panels are designed to provide decades of durable and stable output. Ambient operating temperatures should be between  and
°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 gases or vapors
• 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 e.g.
coastal areas.

MAINTENANCE
CLEANING INSTRUCTIONS
RECTwinPeak 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.
Cleaning of the panel 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 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 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, repeat the cleaning
process. If stains require more effort to be removed, Iso-propyl alcohol of a concentration less than . Acid or Alkali detergent may not be used
Use of high pressure hoses or cleaners is not permied as these may damage the panel, 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 panels, consult the Cleaning Information Sheet available to download from the online REC Installer Portal www.
recgroup.com/installers.
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. Please recycle according to local guidelines and regulations.
< 60 mm >
< 30 mm >
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 RECTwinPeak 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 overtightening, as this can deform the cable insulation

• 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
