FLEX60 modules are not intended for installation
by unqualified end users. These instructions are
to be retained for future reference in case of
maintenance, ownership change, or disposal.
General & Electrical
Safety Information
• Danger! These modules can produce lethal
electrical voltages when connected in series.
Read all safety information prior to handling.
Failure to adhere to the following safety
guidelines can lead to arcs, fires, and electric
shock hazards.
• The module is considered in compliance with
UL 1703 only when the module is mounted
in the manner specified by the mounting
instructions below.
• Any module without a frame (laminate)
shall not be considered to comply with the
requirements of UL1703 unless the module
is mounted with hardware that has been
tested and evaluated with the module under
this standard or by field inspection certifying
that the installed module complies with the
requirements of UL 1703.
• The PV modules should only be used for the
purpose for which they are intended.
• Concentrated or artificial sunlight shall not
be directed onto the PV module.
• All work on the PV system should be
performed by qualified personnel only.
• Warning! Solar modules generate direct
current (DC) when exposed to light. Breaking
or opening a connection under load, i.e. when
current is flowing, can cause an electric arc
which will not self-extinguish.
• Never work on the system or module under
load.
• Always turn o and disconnect the inverter
or other loads before working on the system.

3
• Under normal conditions, a photovoltaic
module is likely to experience conditions
that produce more current and/or voltage
than reported at standard test conditions.
The requirements of the National Electrical
Code (NEC) in Article 690 shall be followed
to address these increased outputs. In
installations not under the requirements of
the NEC, the values of Isc and Voc marked on
this module should be multiplied by a factor
of 1.25 when determining component voltage
ratings, conductor ampacities, overcurrent
device ratings, and size of controls connected
to the PV output.
• A module without a frame (laminate) shall
not be considered to comply with the
requirements of UL 1703 unless the module is
mounted with hardware that has been tested
and evaluated with the module under this
standard or by a field Inspection certifying
that the installed module complies with the
requirements of UL 1703.
• A module with exposed conductive parts
is considered to be in compliance with UL
1703 only when it is electrically grounded in
accordance with the instructions presented
below and the requirements of the National
Electrical Code.
• Installing solar photovoltaic panels and
systems requires specialized skills and
knowledge. Do not attempt to install these
panels if not qualified to do so.
• Installation should only be performed by
qualified persons.
• The installer assumes all risks of injury that
might occur during installation, including but
not limited to, the risk of electric shock.
• Danger! A single module generates more
than 30V DC when exposed to sunlight and
system voltages can be as high as 1000 V.
Contact with voltages greater than 30V DC
can be hazardous, leading to electric shock
and possibly death.
• Danger! Even though it is safe to walk on the
FLEX60 modules, it could become dangerous
if the top surface has been damaged,
degrading the dielectric resistance of the
module. This could lead to electric shock.
Have qualified personnel ensure all modules
surfaces are undamaged before walking on
them.
• Danger! Water exposure can lead to
increased risk of electric shock if the
module’s encapsulation system has been
compromised. Have qualified personnel
ensure there is no leakage current and the
system is in safe working order before walking
on or working on the modules.
• Danger! The FLEX60 modules may become
slippery when wet. This could cause a slip
hazard. If modules are wet, walk carefully,
and keep your center of gravity. Failure to
do so could result in a fall hazard leading to
personal injury. If working on a roof without
a parapet or other curb type system, fall
protection needs to be deployed.
• Danger! Do not stand or walk on modules
unless they are clean. Dirt and debris could
damage the outer surface of the module
exposing electrical components leading to
electric shock.
• Danger! Do not drop objects such as tools
onto the modules. This could damage the
modules encapsulation surfaces exposing
electrical components leading to risk of
electric shock.
• Warning! Short circuits on the DC side of
the installation can cause arcing. Unlike
arcs occurring in low voltage AC wiring,
these arcs are not self-extinguishing. The
high temperatures generated by these arcs
can destroy connectors. If not handled
and installed according to instructions, PV
modules can present a lethal as well as a fire
hazard.
• Danger! Damaged modules, cables, and
connectors can present a shock hazard
resulting in electrocution and death. Do not
attempt to install, service, remove, touch
or modify a damaged module. Damaged
modules should only be removed by qualified
professionals wearing appropriate personal
protection equipment for high voltage. If
damaged modules are found, they should
be immediately identified and secured from
access by unauthorized individuals. Never
attempt to remove or otherwise service a
damaged module if it is wet or raining.
• Danger! To service a module, (1) isolate the
string from others in the system, (2) use
blackout blankets on the entire string to
remove voltage from the system and then (3)
disconnect the target module. You may then
remove the module from the roof keeping the
blackout blanket over the module to prevent
voltages from developing during removal.
Failure to follow these procedures may lead
to electric shock.
• All electrical work must be performed
by qualified personnel only. All electrical
material must be suitable for DC and rated

4
for the existing system voltage. If exposed
to sunlight, the electrical material must be
UVresistant.
• String configuration should be planned in
accordance with inverter manufacturer’s
instructions.
• If the installation is taking place in Canada, it
must be in accordance with CSA C22.1, Safety
Standard for Electrical Installations, Canadian
Electrical Code, Part1.
Fire Safety
• The presence of photovoltaic modules and
support structures (racking systems) on a
roof can change the roofing system’s fire
performance.
• Roof construction and photovoltaic system
support structures may aect the fire safety
of a building. Improper installation may
create a hazard in the event of a fire.
• The module is certified by CSA for use over a
Class ATPO, EPDM and PVC roofing systems
when installed per these instructions. They
are not certified for other applications.
• The Sunflare wire tray is required to maintain
the fire rating of the modules.
• Only Butyl based adhesives are certified
to adhere the Flex60 modules to a roof
membrane.
• Use components such as ground fault circuit
breakers and fuses as required by local
authorities.
• Provide rapid shutdown devices per the NEC.
• The fire rating of this module is valid only
when mounted in the manner specified in
the mechanical mounting instructions in this
manual.
• Consult your local authority for guidelines
and requirements for building and or
structural fire safety.
• Do not install this module near flammable
materials or materials with flammable
o gasses.
Installation Safety
• Follow all local and national safety
precautions when on a roof, including but not
limited to fall protection, gloves, helmets, and
safety glasses.
• Warning! A photovoltaic panel can act as a
sail in even low wind conditions knocking
or pulling an installer o a roof. In addition,
panels can become missiles if unsecured and
blown away by the wind. A flying module
can injure roofers or people on the ground.
Use all appropriate precautions including fall
protection and module capture devices to
ensure safe handling in the event of winds
or wind gusts. Note, wind gusts can be
unpredictable and are not always preceded by
increased wind speeds. Care must be taken to
ensure panels are always safely secured.
• When handling electrical components use
all appropriately rated personal protective
equipment for handling any possible voltages
at the job site.
• Warning! Do not install solar systems when it
is raining or the work surfaces are wet, icy, or
otherwise slippery. This could lean to personal
injury.
• Warning! Do not install in the rain, snow or in
windy conditions. This could lean to personal
injury.
• Avoid exposing cables to direct sunlight to
help prevent their degradation over time.
• Danger! Never open electrical connections
(such as connectors) when the circuit is under
load.
• Danger! Contact with electrically charged
parts of the panels, such as terminals, can
result in burns, sparks and lethal shock
whether or not the panel is connected.
• Keep unqualified persons away from the work
area and the system during transportation
and installation.
• Completely cover the module with an opaque
material during installation to prevent
electricity from being generated.
• Do not wear metallic jewelry including ear,
nose, and lip rings, watchbands, pins, or any
other metallic object during installation or
troubleshooting of photovoltaic systems.
• Use only insulated tools that are approved
for working on electrical installation at the
voltages possible present at the job site.
• Follow all safety regulations and instructions
in the installation manuals for all components
of the system.

• Do not remove or modify any leads or
connectors provided with your module.
Doing so could result in electrical shock,
arcing, and fires as well as void the module’s
warranty.
• Use only MC4 connectors from Multi-
Contact when connecting to these modules.
• When cutting the wire tray, use all relevant
personal protections equipment per OSHA
guidelines. Cut the tray and cover prior to
installation and away from modules and the
roof surface to prevent accidental damage
to those components.

Handling Safety
• System designers and installers are
responsible for proper support structure
design. Sunflare is not responsible for
supporting structures, including but not
limited to the roof structure.
• Follow all local, regional, and national
statutory regulations and obtain all required
building permits.
• Only use equipment, connectors, wires, and
support systems suitable for solar electric
systems.
• Do not lift or carry the module by its junction
box or electrical leads.
• Do not stand or step on the module until they
are fully installed.
• Do not stand or walk on modules unless they
are clean. Dirt and debris underfoot could
cause damage to the surface of the module
reducing its electrical performance.
• Do not drop the module or allow objects to
fall on the module.
• Do not place heavy or sharp objects on the
module.
• Use only original packaging when
transporting or moving the modules.
• Do not disassemble the modules or
remove any nameplates, serial numbers, or
components from the modules.
• Do not apply paint or adhesive to the
module.
• Do not modify the module in any way.
Unique Identifier
A record of the modules serial numbers should
be made before installation and this should be
included in the system documentation to be saved.
The module’s serial number is located on the back
of the module near the name plate and on the
front side of the module on the top right next to
the j-box. The serial number contains the factory
identifier, date code, and a unique identifying
number as shown in the example below:
• Warning! Do not scratch, hit or damage
the topsheet or the backsheet in any way.
Damage to these components could create an
electric shock hazard.
• A panel with a damaged or torn topsheet or
backsheet cannot be repaired and must not
be used.
• Work only under dry conditions, and use only
dry tools. Do not handle panels when they are
wet.
• Danger! Keep uninstalled panels in their box
until it is time to install them. Make jumper
connections to the J-boxes immediately upon
installation to keep water and debris from
penetrating the j-box connectors. If immediate
connection isn’t possible, take measures to
prevent water and dirt from entering the j-box
connectors. Failure to protect the electrical
connections could result in electrical arcs
leading to fire and possibly shock hazards.
• Danger! All electrical contacts should be kept
dry and clean. Failure to do so could lead to
electrical arcs resulting in fire and possible
shock hazards.
• Keep all connectors and wires away from the
roof or any area which may collect water.
• Modules should not be subjected to
concentrated loads or stresses during or
after installation other than those from
environmental factors such as wind and snow
loads.
• Warning! Do not attempt to roll or fold the
modules. Doing so could result in internal
electrical damage leading to arc faults and
fires.

The FLEX60 module is certified by CSA as part
of a Class A roofing system per UL 790 when
installed over TPO, EPDM, and PVC roofing
systems when the following requirements are
met:
• The FLEX60 module with Heliobond and the
Sunflare raceway wire management system
is certified as Class A over any Class A TPO
roofing constructions. The maximum slope is
1/4:12 unless the certified construction has a
non-combustible barrier board directly under
the roofing membrane. In that case, the max
slope is equal to that of the certified roofing
construction.
• The FLEX60 module with Heliobond and the
Sunflare raceway wire management system
maintains Class A fire ratings when installed
in combination with any Class A EPDM or
any Class A PVC roofing construction that
includes a non-combustible barrier board
directly under the membrane as specified in
the roofing manufacturer’s listing. The max
slope is equal to that of the certified roofing
construction.

Notes: (1) Max slope “Per Listing” means per the
roofing systems listing prior to the addition of the
FLEX60 module. (2) The cover board must be directly
under the roofing membrane.
Roofing Membrane Manufacture Approvals
The Flex60 module is fully engineered to reduce
stresses on roofing membranes and provide a
compatible interface. Never-the-less, before
installing Flex60 with Heliobond PVA 600BT
per these instructions, you must obtain approval
from the roof membrane manufacturer. Ensure
you follow all their recommendations and
requirements. Sunflare makes no guarantees nor
warranties in relation to the roofing membrane
and therefore takes no liability for damage or
leaks in the membrane that might be caused from
installing the modules.
Roof Membrane Prep
The roof surface must be thoroughly cleaned
prior to installation and primed if required to
meet load requirements. The surface needs to be
free from dust and dirt prior to module adhesion.
Failure to properly clean the roofing membrane
can result in much lower load capacities than
calculated and could result in module adhesive
failures resulting in an electrical arc and flying
debris hazards that could lead to fires and
personal injury.
Besides dust and debris, the roof surface must
be dry and free from water, ice or snow prior
to module installation. In addition, the roofing
surface must be between 40°F -120°F (4°C
to 49°C) during installation. Failure to follow
these requirements will result in poor adhesion
that could lead to premature failure resulting in
electrical arcs and fires, and flying debris and
personal injury. In addition, poor adhesion due
to insucient roof prep can result in moisture
conditions under the modules that facilitates
unwanted microbial buildup. This could lead
to mold and rot of the laminate and the roof
membrane. Sunflare will not take liability
for degradation or failure of the module or
the roofing membrane resulting from poor
installation.
To meet the required load capacity, it might
be necessary to prime the roofing surface. Use
only primers specified by the roof membrane
manufacturer and follow all manufacturers
instructions for application. Immediately install
the FLEX60 module upon completion of the
priming of the surface.
Module Installation
After the roof has been cleaned to the
requirements above, the module can be stuck
down to the roof. Use chalk lines or other
methods to ensure a straight edge for placing
the modules. Place the modules so their j-boxes
are facing the modules of the next row as shown
in Figure 1 to form a row pair. Ensure there is
a 1.625” ± 0.25” (1-5/8” ± 1/4”) gap between
adjacent module rows. Within a row, the modules
should be installed right next to each other with a
0” gap between them. This is to ensure that water
does not pond between modules. When sticking
the modules down to the roof, first remove the
release sheets from the adhesive on the back of
the module. Align the j-box short edge of the
modules to the chalk line and roll the module
down onto the roof. The adhesive is pressure
activated. Apply a pressure of 15 psi across all 6

areas of the modules that have adhesive. Use a
soft clean roller to apply the force evenly across
the module. Hard or dirty rollers as well as dirty
modules may damage the modules top surface.
Figure 1 – Ensure proper gap between module pairs.
Figure 2 – Install wire trays between junction boxes.
1-5/8” GAP
Wire Tray Installation
The Sunflare raceway is designed to manage wire
runs and house module level power electronics,
such as optimizers or microinverters. The
raceway provides an aesthetic finish to your array
while protecting the wires and power electronics
from UV exposure.
There are four components to the raceway, the:
(1) bottom tray, (2) top cover, (3) coupler, and (4)
end cap. The tray is designed to fit between the
j-boxes of the module as shown in Figure 2.
The tray comes with adhesive already applied
along the bottom. Ensure proper alignment prior
to installation since removal and realignment
is very dicult after the adhesive touches the
laminate or the roofing. Clean dust, dirt, and oils
from the top of the modules and the roofing
prior to applying the tape. In most circumstances
soap and water is sucient. If required, IPA can
be used to clean the module’s top surface. Follow
the roofing manufacturer’s instructions for cleaning
the roofing surface. Ensure all surfaces are dry and
meet the adhesive application temperatures of
40°F -120°F (4 °C to 49 °C). Failure to follow these
instructions could result in adhesive failure.
Butyl Adhesive
2-sided butyl adhesive is tape pre applied If
products come without the pre-applied tapes, it
can be field applied to the back side of the module
and the bottom of the tray. Only HelioBond PVA
600BT by HB Fuller has been approved for use
with Sunflare modules and wire trays. Do not use
any other adhesive. Doing so could void your
warranty and lead to product failures.
Install a 4” wide adhesive strip to the module and
tray prior to installing them on the roof. Clean the
adhesion areas to remove all oils and dirt. Ensure
the module and tray are between 40°F -120°F (4
°C to 49°C). Apply the tape along all edges of
the backside of the module and across the center
as shown in Figure 3. Ensure the tape makes a
complete seal all the way around the module to
keep water from penetrating under the module.
Apply the tape across the entire length of the
bottom of the wire tray.

Electrical Installation
Modules in Series
The FLEX60-160W to FLEX60-185W modules
are strung in pairs to match power ratings
for typical MLPE devices. Electrically connect
adjacent modules (across rows) using 1’ jumper
cables as shown in Figure 4. Jump only one
j-box per module. The other j-box will be
connected to the MLPE. Jump the same j-boxes
for every module pair.
Figure 4 – Create MLPE module pairs using jumpers.
Figure 5 – Connect pair of modules to MLPE.
Figure 6 – Connect MLPEs together
Modules with power ratings greater than 185W
are typically connected directly to a single MLPE
and thus will not be jumped to an adjacent
module as shown in Figure 4.
MLPE Installation
The module level power electronics such as
rapid shutdown devices or optimizers are placed
inside the center of the wire tray and connect the
remaining j-boxes as shown in Figure 5.
Repeat this for every MLPE on the string and then
homerun the first and last MLPEs all the way back
to the combiner box or inverter.
Manage all wires such that they will stay
hidden under the wire tray top cover once it is
installed. Use only solar ties or other polymeric
wire ties with application appropriate UV
and environmental resistance. Do not use
commercially available wire ties from the
hardware stores even if they say UV rated. Do not
use metal ties or clips.
Raceway Top Cover Installation
The raceway top cover provides an appealing
aesthetic to the array by hiding the wires and
MPLEs. It also protects these components from
physical damage and degradation from UV
exposure.
The top cover is three module widths long and
snaps onto the tray. However, before installing the
top covers, couplers need to be installed at the
end of the rows as shown in Figure 7 and across
every 3 adjacent modules as shown in Figure 8
so adjacent top covers can be joined together.
The coupler comes with the same adhesive as the
wire tray. Follow the same installation guidelines
as the wire tray prior to sticking the coupler at
its designated location. Ensure proper placement
prior to fixing the coupler since removal and
realignment can be dicult.
Once the MLPE is connected to the pair of
modules it is ready to be connected to the MLPE
of the neighboring pair of modules as shown in
Figure 6.

Figure 9 – Align top cover to end of row.
Figure 10 – Top covers joined at coupler.
Figure 11 – Cement the end cap to the top cover
Figure 8 – Install couplers across every 3 modules
Align the top cover to the edge of the row and
snap it down to the wire tray as shown in Figure
9. Repeat this process across the row ensuring
there are no gaps between the covers at the
joining couplers as shown in Figure 10. Measure
and cut the last cover to the required length prior
to installation.
Finally, install the end caps to the top covers at
both exposed ends of the row as shown in Figure
11. Use an outdoor rated PVC cement to join the
end cap to the top cover. Do not cement the end
cap to the coupler. Doing so will make removing
the top cover dicult when servicing the system.
For additional information and a photo
walkthrough of the installation process, refer to
the “FLEX60 Installation Supplement” document.
Grounding
Per its certification, the Sunflare FLEX60 module
is not to be grounded. It is double insulated
and has no exposed metal components. Ensure
you use only no conductive polymeric wire
management devices and components within the

array. Using metal components could result in
grounding requirements and a safety hazard.
Electrical Installation
Whenever possible use the jumper cables
provided by Sunflare. They are cut to the correct
size and have the proper mating connectors for
the modules. For making homerun cables follow
the instructions and requirements below.
Conductors
Use only USE-2 or UL 4703 “PV Wire” for jumpers
and homerun cables. These wires meet NEC
requirements per Section 690.31 (C) for use in
outdoor exposures in solar arrays. Minimum wire
gauge is AWG 12 (4mm2). Use larger gauge wire
(lower gauge number) for longer runs or where
reduced electrical resistance is desired. Follow
all NEC guidelines for wire size and installation
requirements.
Connectors
Use only Multi-Contact MC4 plug connectors
from Staubli (www.staubli-alternative-energies.
com). Using any other connector with a Sunflare
FLEX60 module will void the warranty.
Fuses
All Sunflare FLEX60 modules must be protected
by appropriate overcurrent protection devices
per NEC guidelines. The maximum series fuse
rating for the FLEX60 module is 12A. Follow
all NEC guidelines for fuse rating requirements
including size and type.
Connecting in Series
Only connect FLEX60 modules in series strings
and protect each series from other paralleled
strings with proper overcurrent protection. It
is reccomended that no more than 25 modules
should be in series per string.
Mechanical Load Rating
For design purposes, ASC7-16 Section 30
“Components and Cladding” should be used for
calculating the load requirements on the module.
Do not use the photovoltaic specific paragraphs
in Section 29 for load development on the
FLEX60 product. Those sections are only relevant
to products that are mounted above the roof
surface and thus do not apply to the stick down
FLEX60 module. Set the eective wind area equal
to one panel.
Maintenance and Repair
The Sunflare FLEX60 module is designed for
a 25-year life and under normal circumstance
should require no maintenance. However, due to
the wide variety of environmental conditions and
installation practices it is recommended to fully
inspect the system and all connections every 6
months.
Read these installation instructions thoroughly
before inspecting or servicing a Sunflare FLEX60
system. Inspection and service should only
be carried out by qualified personnel using
all appropriate OSHA recommended personal
protection equipment. Disconnect the system
prior to inspection. Replace any wires and
connectors that shows signs of wear or damage.
Replace any wire tray and cover that is damaged
or significantly degraded. If a module is damaged,
leave it in place. Do not attempt to remove the
module from the roofing surface unless it poses
an electrical risk. Doing so might damage the roof
membrane.
If service or inspection is required, disconnect the
string with the damaged module from all other
strings and use black out blankets to cover all
modules in that string. Check that voltages are
below 5V. Then, disconnect the broken module
from the string and plug the ends of its j-box
connections using the MC4 Staubli sealing caps
PV-BVK4, and PV-SVK4. Then jumper around the
module and reconnect the string.
If the damaged module has compromised
electrical encapsulation it can be removed or
encapsulated in place using a black silicone
sealant. Sunflare will not be liable for roof
damage if removing the module nor any issues
that may arise from encapsulation by applying a
sealant.
Cleaning
The Sunflare FLEX60 module does not require
cleaning. If cleaning is found necessary to achieve
desired power performance, then it should only
be cleaned by professional cleaners. Prior to
cleaning the system, it must be inspected for
safety and approved for cleaning by qualified
personnel. Failure to inspect the system could
lead to electric shock and possibly death.
Never use brushes, soaps, detergents or robotic
cleaners intended for use over glass modules to
clean the FLEX60 modules. Use only water, and
if required a soft sponge. Do not use soap or
detergents to clean the module. Do not walk onto
the array unless absolutely necessary. Do not walk
on dirty modules or over clean modules with dirty
shoes. Debris underfoot can damage the topsheet
of the module leading to power loss and possibly
module failure.
