KYOCERA Assembly and Maintenance Instructions, September 201
Safety
Solar modules generate power, producing voltage and cur-
rent as soon as they are exposed to light. A single solar mod-
ule generates a voltage of below 50 VDC; if several modules
are connected in series, the voltages of the individual mod-
ules accumulate and can pose a hazard.
Hazard!
Potentially fatal risk due to electrical shock if
damaged solar modules are touched.
• Only touch solar modules with fractured or
broken front glass or a damaged rear foil if
you are wearing rubber gloves.
• Only touch damaged solar modules if it is
absolutely necessary.
Warning!
Risk of falling when working on roofs.
• Use suitable fall protection equipment.
•
Observe the accident prevention regulations.
Warning!
Risk of injury from falling objects.
• Cordon off a safe distance around the haz-
ardous zone when working on roofs.
Caution!
To avoid damage to the solar module, please
observe the following points:
• Do not apply paint or any adhesives to the
rear side of the solar module.
• Never use the junction box or the solar cable
to carry the unit.
• When handle the modules, do not hold them
by supporting only one side of the long
frame.
• Do not expose the solar module to concen-
trated light.
• Do not allow any objects to fall upon the
solar module.
•
Avoid scratches to the front glass.
NOTE
The frame of the solar module may have sharp edges and
may cause injury. Wear suitable gloves, such as leather
gloves with padding in the palm and finger areas.
4 Assembly
Assembly work may only be performed by
trained and qualified personnel.
4.1 Safety information relating to assembly
Caution!
KYOCERA solar modules are “non-explosion-
protected operating equipment”.
• Do not install the solar module close to
flammable gases or vapours.
Hazard!
Potentially fatal risk if live parts are touched.
• Cover the solar module with opaque foils or
materials during assembly.
Warning!
Risk of falling when working on roofs.
• Use suitable fall protection equipment.
• Do not perform assembly work in strong
winds.
• Only perform assembly work in dry weather
conditions.
•
Observe the accident prevention regulations.
4.2 Select the location
NOTE
Before installing the PV system, contact local authorities to
determine the necessary permits, installation and inspection
requirements. During assembly, pay attention to the local
building standards.
The solar modules can be installed on roofs or open space on
support structures. To achieve maximum power yields for
feeding into the public grid, the following should be observed
when selecting the installation site: The solar irradiation
should be as high as possible distributed throughout the year.
To this end, the surface of the solar modules in the northern
hemisphere must face south and the surface of the solar
modules in the southern hemisphere must face north. The
ideal module slope is approx. site latitude. While a bigger
module slope leads to energy losses, smaller module slope
can also lead to high accumulations of non-slipping snow on
the module, which might cause damages to the module or its
frame. Install the solar modules where they are not shaded by
obstacles such as buildings or vegetation. Pay special atten-
tion to avoid partial shadowing of the solar modules by close-
by objects. The solar modules should not be installed in the
area with direct exposure to saltwater droplet (Guideline :
within 50 m of a saltwater body). In the zone between 50 m
and 200 m from a saltwater body, the PV modules should be
installed as roof mounted only. For more information about
the selection of the site, please contact the KYOCERA cus-
tomer service.
Caution!
Risk of breaking the solar module.
• Do not walk across or step on the solar
module.
Caution!
Risk of injury by the solar module frame.
• Do not touch the solar module with bare
hands.

KYOCERA Assembly and Maintenance Instructions, September 201
4. Preparatory work for assembly
The solar module must be mounted to a support structure.
Please observe the information provided by the mount manu-
facturer when selecting the support structure.
If installed on a roof, the solar modules must be mounted on
a fire-resistant surface.
4.4 Mounting the solar module
Please observe the following during assembly:
• A clearance of at least 50 mm needs to be kept be-
tween the module frame and the attachment surface.
This allows the cool ambient air to circulate below the
solar module. This is necessary for optimum perfor-
mance in all application ranges.
• There should be a clearance of at least 3.2 mm be-
tween the individual module frames to allow heat-
related expansion.
• The solar modules can be installed in either portrait or
landscape position.
• If high accumulations of snow on the module array oc-
cur on site, the lower part of the module frames could
be damaged when slipping snow is piled up there.
This kind of damage needs to be avoided by an ap-
propriate countermeasure e. g. attaching support parts
at the lower side frames of the modules.
• When selecting the material for the support structure,
pay attention to the electrochemical series in order to
avoid galvanic corrosion between different kinds of
metal.
• Fasten modules firmly to a support structure designed
to withstand the local wind and snow loads
• The glass surface may have color variations depend-
ing on the viewing angle or installation circumstance.
This is a normal characteristic of the glass and doesn't
affect the quality of the solar module. Do not touch the
glass surface with bare hand to avoid contamination.
Clean the glass surface with a soft wet cloth without
detergent if it is contaminated with oil or fingerprints.
Do not rub the glass surface with something hard like
a metal or sharp edge.
4.4.1 Bolting
Assembly material
• Stainless steel screws, diameter 8 mm (4 units)
• Screw body length is 25.4mm or less.
• Stainless steel nuts with locking teeth or stainless
steel nuts, spring washers and flat washers. (4 units)
NOTE
No holes may be drilled into the module frame.
Procedure
 Please see the drawing in Appendix 1 of these
instructions for the positions of the mounting holes.
 Drill the required assembly holes to the support struc-
ture.
 Tighten the screws with adequate torque (usually 12.5
Nm) to securely attach the solar module to the sup-
porting frame. As adequate torque figure depends on
selected bolt nuts, follow the manufacturers' recom-
mended numbers.
4.4.2 Clamps
Assembly material
• Rustproof module clamps (at least 4 units).
• Please observe the information provided by the
manufacturer when selecting the clamps.
Installation with long side of frame
-must be at least 24mm long respectively.
-must overlap the module frame by at least 5mm.
NOTE
The module clamps
- must not bend the module frame.
- must not touch the front glass.
- must not cast a shadow on the front glass.
- must not damage the surface of the frame.
Procedure
 Define the positions of the clamps based on the draw-
ings in Appendix 2.
 Tighten the module clamps to the torque stated by the
clamp manufacturer.
 Fasten modules firmly by clamps designed to with-
stand the local wind and snow loads.
5 Electrical connection
5.1 Safety information relating to the electrical
connection
5.2 Wiring of the solar modules
NOTE
The maximum system voltage of solar modules connected to
each other may not exceed 1000 VDC. When designing the
system, please note that the module voltage increases when
the temperatures are low. Do not connect the modules in
parallel without max. over current protection.
Under normal conditions, solar modules can supply higher
currents and/or a higher voltage than reported at the standard
test conditions (see chapter 2. “Technical Data”).
Therefore, when determining component voltage ratings,
conductor current ratings, fuse sizes, and the size of controls
connected to the output of the solar modules, the stipulated
values of I
SC
and V
oc
should be multiplied with a factor of 1.25.
Only interconnect modules of the same type within a system.
The solar modules are equipped ex-works with 4 mm
2
-solar
cables. The solar cables have SMK PV-03 connectors. These
connectors are designed for series wiring only. Always use
special solar cables with a minimum conductor size of 4 mm²
and suitable PV-connectors for further series or parallel wiring.
When wiring, proceed as follows:
• Ensure the poles are connected correctly and that the
plugs are connected properly without gaps
• Observe the minimum bending radius of 29 mm of the
solar cables that are used.
Only specially trained and qualified personnel
may make the electrical connection.
Hazard!
Potentially fatal risk if live parts are touched.
• Never disconnect or connect electrical con-
tacts when under load.
• Only use dry, insulated tools for the electrical
assembly work.
• Never touch live parts with bare hands.
• Cover the solar module during installation with
opaque foils or materials.
•
Do not wear any metal jewellery.

KYOCERA Assembly and Maintenance Instructions, September 201
• Plug and socket connections shall only be mated with
those of the same type from the same manufacturer.
5. Connection of the solar modules
Please observe the information provided by the manufacturer
of the inverter when connecting the solar modules to an in-
verter.
5.4 Grounding of the solar modules
To minimise the risk of an electrical shock, the frames of the
solar modules should be grounded.
Assembly material
• Stainless steel screw, diameter 6 mm with stainless
steel serrated washer and stainless steel nut
• suitable grounding cable
NOTE
Ensure that the anodised layer of the frame is penetrated and a
secure electrical contact is created with the frame.
Procedure
 Please see the drawing in Appendix 1 of these in-
structions for the positions of the grounding holes.
 Screw the grounding cable firmly to one of the ground-
ing holes using the stainless steel screw and a min.
torque of 8 Nm.
6 Maintenance
Only specially trained and qualified person-
nel may service the solar system.
KYOCERA solar modules are designed for long-term service
and are almost maintenance-free.
6.1 Safety information relevant for maintenance
6.2 Cleaning the solar module
When the slope is adequate (> 15 degrees), the solar mod-
ules do not need to be cleaned thanks to the self-cleaning
effect of the rain. If heavily soiled, clean with plenty of water,
a mild detergent and a soft cloth/sponge.
6. Solar module maintenance
The system should be inspected once a year with regard to
the following:
• Secure hold and no rust on any of the attachments
• Secure connection, cleanliness and that all cable con-
nections are free of corrosion

Please read this manual carefully before installing the modules.
6C-215307
1. INTRODUCTION
As the world leader in the development and application of
high technology ceramic/silica materials, Kyocera offers a
wide range of highly efficient and reliable crystalline silicon
solar photovoltaic (PV) power modules. Kyocera began to
extensively research PV technology in 1975 and
commenced manufacturing operations in 1978. Since then,
Kyocera has supplied millions of cells and modules
throughout the world. With years of experience and
state-of-the-art technology, Kyocera provides the highest
quality PV power modules in a range of sizes designed to
meet the requirements of the most demanding energy users
worldwide.
2. APPLICATIONS
Kyocera PV module (hereinafter referred to as “the PV
module”) is a reliable, virtually maintenance-free direct
current (DC) power source, designed to operate at the
highest level of efficiency. The PV module is ideal for
residential, commercial, or utility applications; grid-tie or
off-grid applications and those with or without using storage
batteries.
3. WARNINGS & SAFETY
PV modules generate electricity when exposed to light.
Arrays of many modules can cause lethal shock and burn
hazards. Only authorized and trained personnel should
have access to these modules. To reduce the risk of
electrical shock or burns, modules may be covered with an
opaque material during installation. Do not touch live
terminals with bare hands. Use insulated tools for electrical
connections. Do not use these modules with solar
concentration.
PERMIT
・ Before installing your PV system, contact local
authorities to determine the necessary permits,
installation and inspection requirements.
INSTALLATION AND OPERATION
・ The PV module is considered to be in compliance with
UL1703 only when the PV module is mounted in the
manner specified by the installation manual.
・ Systems should be installed by qualified personnel only.
The system involves electricity, and can be dangerous if
the personnel are not familiar with the appropriate safety
procedures.
・ Do not step on the module.
・ Although the PV module is quite durable, the glass can
be broken if it is dropped or hit by tools or other objects.
This will render the PV module inoperable.
・ The module frame is made of anodized aluminum, and
therefore corrosion can occur if the module is subject to
a salt-water environment and/or is in contact with
another type of metal (galvanic corrosion). Pay attention
to the above and take appropriate measures to prevent
corrosion when selecting the installation environment,
material of support structure, and clamping method.
・ The PV module frame(s) must be attached to a support
structure by one of the methods described in Section 6,
INSTALLING PV MODULES.
・ Module support structures used to support the PV
module(s) should be wind rated and approved by the
appropriate local and civil codes prior to installation.
・ Do not expose the back of the module to direct sunlight
・ In Canada, installation shall be in accordance with CSA
C22.1, Safety Standard for Electrical Installations,
Canadian Electrical Code, Part 1.
CAUTION
・ Do not touch the PV module with bare hands. The frame
of the PV module may have sharp edges and may cause
injury. Wear suitable gloves, such as leather gloves with
padding in the palm and finger areas.
FIRE RATING
・ The PV module is comprised of a glass front surface and
polyethylene terephthalate (PET) backsheet and has a
Class C fire rating in IEC61730 and ULC1703.
・ The fire rating of the PV module is valid only when
mounted in the manner specified in the installation
manual.
・ For Fire Performance Test it is designated as Type 2.
・ The PV system (PV module(s) combined with support
structure) can attain Fire Class A when installed in a UL
listed structure according to the structure manufacturers
installation instructions.
GROUNDING
・ The PV module with exposed conductive parts is
considered to be in compliance with UL1703 only when
it is electrically grounded in accordance with the
instructions presented below and the requirements of
the National Electrical Code.
・ Refer to “8.GROUNDING” section.
BATTERY
・ When PV modules are used to charge batteries, the
battery must be installed in a manner which will ensure
the performance of the system and the safety of its users.
Follow the battery manufacturer’s safety guidelines
concerning installation, operation and maintenance
recommendations. In general, the battery (or battery
bank) should be kept away from people and animals.
Select a battery site that is protected from sunlight, rain,
snow, debris, and is well ventilated. Most batteries
generate hydrogen gas when charging which can be
explosive. Do not light matches or create sparks near
the battery bank. When a battery is installed outdoors, it
should be placed in an insulated and ventilated battery
case specifically designed for this purpose.
KUxxx-6MxA Series
・ When handling the modules,
DO NOT HOLD THEM BY
SUPPORTING ONLY ONE
SIDE OF THE FRAME
BECAUSE IT CAN CAUSE
SEPARATION OF THE
GLASS AND FRAME.

4. SITE SELECTION
In most applications, the PV modules should be installed in
a location where they will receive maximum sunlight
throughout the year. In the Northern Hemisphere, the
modules should typically face south, and in the Southern
Hemisphere, the modules should typically face north.
Modules facing 30 degrees away from true South (or North)
will lose approximately 10 to 15 percent of their power
output. If the module faces 60 degrees away from true
South (or North), the power loss will be 20 to 30 percent.
Install the solar modules where they are not shaded by
obstacles such as buildings and vegetation. Pay special
attention to avoid partial shadowing of the solar modules by
objects during the daytime.
The PV modules should not be installed in the area with
direct exposure to saltwater droplet (Guideline : within
164’(50m) of a saltwater body). The PV modules should
only be installed as roof mounted in the zone between 164’
(50m) and 656’(200m) from a saltwater body.
5. MODULE TILT ANGLE
The PV modules produce more power when they are
pointed directly at the sun.
For grid-tie installations where the PV modules are attached
to a permanent structure, PV modules should be tilted at an
angle equal to the site's latitude. This will typically result in
the highest annual energy output.
6. INSTALLING PV MODULES
The glass surface may have color variations depending on
the viewing angle or installation circumstance. This is a
normal characteristic of the glass and doesn't affect the
quality of the PV module. Do not touch the glass surface
with bare hand to avoid contamination. Clean the glass
surface with a soft wet cloth without detergent if it is
contaminated with oil or fingerprints. Do not rub the glass
surface with something hard like a metal or sharp edge.
The PV modules may be installed in various applications
utilizing a variety of support structures and attachment
methods as described below. For UL2703 certified
attaching methods with these modules, please contact
Kyocera. The structure should have enough strength to
maintain the mounting span.
For optimal performance in all applications, clearance
between the module frame and the mounting surface is
required to allow cooler ambient air to circulate around the
back of the module and to avoid module and/or wiring
damage. A minimum spacing of 2” (50mm) is required
between the PV module and the mounting surface around
the perimeter of PV array. A minimum of .13” (3.2mm)
spacing must also be maintained between module frames
to allow for thermal expansion.
When installing modules in a highly snowy area, an
appropriate countermeasure should be considered to
prevent possible damage resulting from heavy snow
accumulation and/or slippage. Any damage caused by
snow or such countermeasures involving module frame
modifications are not covered under warranty.
BOLTING: Use 5/16”(8mm) stainless steel (or equivalent in
corrosion resistance) hardware through the existing .35”
(9mm) diameter mounting holes in the module frame and
then through the holes on the support structure. Tighten the
screws with adequate torque (usually 132in-lb; refer
structure manufacturer specifications). Refer to the module
drawings (Section 12) for the position of mounting holes.
CLAMPING (Standard clamp / Long Clamp):
Fasten modules firmly using standard clamps or long
clamps. Use 1/4” (6mm) or larger bolt and nut, made of
stainless steel or equivalent in corrosion resistance. And
tighten the screws with adequate torque specified by
structure manufacturer.
Clamps must have enough strength to withstand snow/wind
load etc, and must not damage the module frames. Clamps
also must not shade the sunlight incidence on glass surface.
Support structure should support the bottom of module at
least .39” (10mm) width or overlap.
Take measures to prevent module from falling off clamps. If
there is clearance between clamp and module side face
when using insertion systems, take measures to prevent
module from moving (e.g. put plastic parts into clearance).
Refer to the ‘CLAMPING AREA’ (Section 12) for the
clamping position and length of long clamp.

maximum system voltage rating of 1000 volts DC. Some
grid-tie systems operate at or near this voltage rating. Like
other polycrystalline PV modules, the open-circuit voltage
of the PV modules increases as the ambient temperature
decreases. Maximum system voltage is computed as the
sum of the open-circuit voltage of the series-connected PV
modules for the lowest expected ambient temperature.
Refer to the National Electrical Code Article 690-7(A) for
determining the maximum number of the PV module that
can be placed
in series. Temperature coefficients, specific
to the module of use, can be used to provide the most
accurate prediction of module voltage under temperature
extremes.
NOTE: Limit the maximum number of series connection of
the PV module so that the system voltage is 1000V or less.
NOTE: Do not connect the modules in parallel without
maximum over current protection.
NOTE: The minimum radius that the cable can be bent for
the PV module is 1.14” (29mm).
NOTE: Under normal conditions, PV 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.
8. GROUNDING
Before installation, consult the local codes and the
authorities having jurisdiction to determine the necessary
grounding requirements. When installing in the US market,
attach all PV module frames to an earth ground in
accordance with the National Electrical Code (NEC) Article
250. Proper grounding is achieved by connecting PV
module frames and all metallic structural members
contiguously to one another using a suitable grounding
conductor. The grounding conductor shall be of copper,
copper alloy or another material suitable for use as an
electrical conductor per NEC. The grounding conductor
must then make a connection to earth using a suitable earth
grounding electrode. Ensure positive electrical contact
through the anodizing on the module frame extrusion by
utilizing one of the following methods.
Attach the grounding conductor:
(1) to one of the .28” (7mm) diameter holes marked
“ground” using 1/4”(6mm) stainless steel bolt. Wrap
conductor around bolt. Tighten the screws with
adequate torque (62 in-lb: UL evaluation torque).
(2) to a ground lug (manufacturer:ILSCO, model:GBL-
4DBT). The lug is attached to one of the .28”(7mm)
diameter holes marked “ground”, using #10-32
stainless steel bolt with 40 in-lb torque.
(3) to a ground lug (manufacturer:ILSCO, model:GBL-
4DBT). The lug is attached to one of the .16”(4mm)
diameter holes marked “ground”, using #10-32
stainless steel tapping machine screw with 30 in-lb
torque. Screw length should be 1/2"(12.7mm) or less.
(4) to a wire bolt (manufacturer:Tyco, model:2058729-1)
using 3/8”(10mm) wire biding nut with 45 in-lb torque.
The bolt is attached to one of the .19”(4.7mm) diameter
holes marked “ground”, using #8-32 (4mm) mounting
washer nut with 25 in-lb torque.
NOTE: A stainless steel star washer or mounting washer
nut, having contact with anodized surface of the frame,
must be employed to break through the anodized layer of
the frame extrusion and electrically connect the grounding
conductor to the conducting aluminum frame material.
NOTE: As a general rule, avoid direct contact of copper or
copper alloy ground conductors with the aluminum frame to
prevent galvanic corrosion. All ground bond securing
hardware in contact with either the aluminum module frame
and/or copper or copper alloy ground conductors must be
stainless steel.
NOTE: Where common grounding hardware (nuts, bolts,
star washers, spring-ring lock washers, flat washers and
like that) is used to attach a listed grounding/bonding device,
the attachment must be made in conformance with the
grounding device manufacturer's instructions.
NOTE: Common hardware items such as nuts, bolts,
star-washers, lock washers and the like have not been
evaluated for electrical conductivity or for use as grounding
devices and should be used only for maintaining
mechanical connections and holding electrical grounding
devices in the proper position for electrical conductivity.
Such devices, where supplied with the module and
evaluated through the requirement in UL 1703, may be
used for grounding connections in accordance with the
instructions provided with the module.

9. BLOCKING DIODES
In systems utilizing a battery, blocking diodes are typically
placed between the battery and PV module output to
prevent battery from discharging at night. The PV module is
made of polycrystalline cells with high electrical “back flow”
resistance to nighttime battery discharging. As a result, the
PV modules do not contain a blocking diode when shipped
from the factory. Most PV charge regulators and inverters
incorporate a nighttime disconnect feature.
10. BYPASS DIODES
Partial shading of an individual module in a source circuit
string (i.e. two or more modules connected in series) can
cause a reverse voltage across the shaded cells within the
module. Module output current is then forced through the
shaded area by the remaining illuminated cells and other
PV modules in series with the partially shaded module(s).
The current forced through the shaded cells within the PV
module(s) causes additional module heating and severe
loss of power. All the PV modules are supplied with factory
installed (non user serviceable) bypass diodes.
The purpose of bypass diodes is to provide a low-resistance
current path around the shaded cells, thereby minimizing
PV module heating and array current losses.
The PV module employs bypass diodes that have:
・ Rated Average Forward Current [IF(AV)] Above
maximum system current at highest PV module
operating temperature.
・ Rated Repetitive Peak Reverse Voltage [VRRM] Above
maximum system voltage at lowest PV module
operating temperature.
11. MAINTENANCE
The PV module is designed for long life and requires very
little maintenance. Under most weather conditions, normal
rainfall is sufficient to keep the module glass surface clean.
If dirt build-up becomes excessive, clean the glass surface
only with a soft wet cloth without detergent. USE CAUTION
WHEN CLEANING THE BACK SURFACE OF THE PV
MODULE TO AVOID PENETRATING BACK SHEET. The
PV modules that are mounted flat (0°tilt angle) should be
cleaned more often, as they will not "self clean" as
effectively as modules mounted at a 15°tilt or greater.
Once a year, check the general condition of the wiring and
check to be sure that mounting hardware is tight. Loose
connections may result in a damaged module or array.
