IMPORTANT SAFETY INSTRUCTIONS
This manual contains important safety instructions for the PV
module that must be followed during the maintenance of PV
modules.
To reduce the risk of electric shock, do not perform any servicing
unless you are qualied to do so.
1. The installation must be performed by a certied installer
/servicer to ensure system integrity and safety.
2. The installation is only allowed after referring and
understanding of GENERAL INSTALLATION MANUAL and
INSTALLATION MANUAL -PHOTOVOLTAIC MODULE-. If
you don’t have your personal copy, please contact your
installer or local Sharp oce listed in Sharp Solar web site :
URL : http://www.sharp-world.com/solar
3. Do not pull the PV cables.
4. Do not touch any surface of module.
5. Do not place/drop objects onto the PV modules.
6. Do not disassemble or attempt to repair the PV module by
yourself.
7. Do not drop the PV module.
8. Do not damage, pull, bend, or place heavy material on cables.
9. Upon completion of any service or repairs, ask the
installer/servicer to perform routine checks to determine that
the PV modules are in safe and proper operating condition.
10. When replacement parts are required, be sure the
installer/servicer uses parts specied by the manufacturer with
same characteristics as the original parts. Unauthorized
substitutions may result in re, electric shock, or other hazard.
11. Consult your local building and safety department for required
permits and applicable regulations.
12. In regions with snow, the module can sustain a snow load of
up to 50cm (when the module is mounted in the portrait
orientation / short frame side facing down) or 100cm (when
the module is mounted in the landscape orientation / long
frame side facing down).
13. As a result of sliding snow, the mechanical load increases
when the number of module rows in the matrix of a PV
installation increases. When mounting the module in the
portrait orientation for more than 3 rows, the accumulated
snow load may cause the lower edge of the module frame to
deform. Take necessary measures (e.g. snow stopper) to
avoid possible damage.
14. Periodically remove any overhanging snow and/or ice from the
module framework as it may cause deformation of the module
frame.
GENERAL INSTRUCTIONS
1. INTRODUCTION
This Installation Manual contains essential information for the electrical and mechanical installation that you must know before
installing SHARP PV modules. This also contains safety information you need to be familiar with. All the information described in
this manual are the intellectual property of SHARP and based on the technologies and experiences that have been acquired and
accumulated in the long history of SHARP. This document does not constitute a guaranty, expressed or implied. SHARP does
not assume responsibility and expressly disclaims liability for loss, damage, or expense arising out of or in any way connected
with installation, operation, use or maintenance of the PV modules. No responsibility is assumed by SHARP for any infringement
of patents or other rights of third parties that may result from use of PV module. SHARP reserves the right to make changes to
the product, specications or installation manual without prior notice.
2. COMPONENTS
3. GENERAL INFORMATION
(INCLUDING WARNING AND SAFETY)
The installation of PV modules requires a great degree of skill
and should only be performed by a qualied licensed
professional, including licensed contractors and licensed
electricians. Please be aware that there is a serious risk of
various types of injury occurring during the installation
including the risk of electric shock. All SHARP PV modules are
equipped with a permanently attached junction box that will
accept variety of wiring applications or with a special cable
assembly for ease of installation, and they do not require
special assembly.

GENERAL WARNING
1. PV modules are heavy. Handle with care.
2. Before you attempt to install, wire, operate and maintain
the PV module, please make sure that you completely
understand the information described in this installation
manual.
3. Contact with electrically active parts of a PV module such
as terminals can result in burns, sparks and lethal shock
whether the PV modules are connected or not.
4. PV modules produce electricity when the sucient
sunlight or other sources illuminate the module surface.
When the modules are connected in series, voltage is
cumulative. When the modules are connected in parallel,
current is cumulative. As a result, a large-scale PV
system can produce high voltage and current which could
present an increased hazard and may cause serious
injury or death.
5. Do not connect the PV modules directly to the loads such
as motor since the variation of the output power
depending on the solar irradiation causes damage for the
connected motor.
1: In the case of a brushless motor, the lock function
becomes active and the hall IC is most likely to be
damaged.
2: In the case of a brush type motor, the coil is most likely
to be damaged.
6. In case of snow build-up, snow would slide easier on the
smooth surface of the module than other parts of the roof.
Snow may suddenly slide, fall o the roof and hit nearby
objects/areas. Take preventive measures (e.g. snow
stopper) when there is possible risk such case would
cause an injury or a damage.
GENERAL SAFETY
1. Consult local codes and other applicable laws concerning
required permits on regulations for installation and
inspection requirements.
2. Before installing a PV module, contact appropriate
authorities to determine permit, installation and inspection
requirements that should be followed.
3. Install PV modules and ground frames in accordance with
applicable rules and regulations.
4. PV modules should be installed and maintained by
qualied personnel. Only installer/servicer personnel
should have access to the PV module installation site.
5. No matter where the PV modules are installed, either roof
mounted construction or any other type of structures
above the ground, appropriate safety practices should be
followed and required safety equipment should be used
in order to avoid possible safety hazards. Note that the
installation of some PV modules on roofs may require the
addition of reproofing, depending on local building/re
codes.
6. In the case that the PV modules are non-integral type,
the module is to be mounted over a re resistant roof.
7. Use PV modules with the same cell size within series.
8. Follow all safety precautions of other components that
are used in the system.
9. In order to avoid a risk of injury or electrical shock, do not
allow anyone to approach the PV module if the person
has little knowledge on PV module or on the measures
that should be taken when PV modules are damaged.
10. Do not shade portions of the PV module surface from the
sunlight for a long time. The shaded cell may become hot
(hot spot phenomenon) which results in solder joints
peeling o. Shading causes drop in generated power
and/or operation failure of the PV modules.
11. Do not clean the glass surface with chemicals. Do not let
water collect on the glass surface for a long time. This
creates a risk of white eorescence (glass disease)
which may result in the deterioration of energy generation.
12. Do not install the PV module horizontally. It may cause
dirt or white eorescence (glass disease) due to water.
13. Do not cover the water drain gap of the frame. There is a
risk of frost damage when the frame is lled with water
cumulation.
14. If there is a risk of sliding snow, an appropriate measure
has to be taken so that PV module frames on lower edge
of PV modules will not be damaged.
15. Do not expose PV module to sunlight concentrated with
mirrors, lenses or similar means.
16. Turn o inverters and circuit breakers immediately,
should a problem occur.
17. In case the glass surface of a PV module is broken, wear
goggles and tape the glass to keep the broken pieces in
place.
18. A defective PV module may generate power even if it is
removed from the system. It may be dangerous to handle
the PV module while exposed to sunlight. Place a
defective PV module in a carton so PV cells are
completely shaded.
19. In case of series connection, the maximum open circuit
voltage must not be greater than the specied maximum
system voltage. The voltage is proportional to the number
of series. In case of parallel connection, please be sure to
take proper measure (e.g. fuse for protection of module
and cable from over current, and/or blocking diode for
prevention of unbalanced strings voltage) to block the
reverse current ow. The current may easily ow in a
reverse direction.
20. Keep modules away from children.
HANDLING SAFETY
1. Do not cause an excessive load on the surface of PV
module or twist the frame. The glass surface can easily
break.
2. Do not stand or step on the PV module. The surface
glass of PV module is slippery.
3. Do not hit or put excessive load on the glass or back
sheet. The PV cell is very thin and can be easily broken.
4. Do not scratch or hit at the back sheet. The back sheet is
vulnerable.
5. Do not damage the junction box or do not pull the cables.
The junction box can crack and break.
6. Never touch junction box or the end of output cables with
bare hands when the PV module is irradiated. Cover the
surface of PV module with cloth or other suitable
suciently opaque material to isolate the PV module from
incident light and wear rubber gloves when handling the
wires to avoid electric shock.
7. Do not scratch the output cable or bend it with force. The
insulation of output cable can break and may result in
electricity leakage or shock.
8. Do not pull the output cable excessively. The output
cable may unplug and cause electricity leakage or shock.
9. Do not drill holes in the frame. It may compromise the
frame strength and cause corrosion.
10. Do not scratch the insulation coating of the frame (except
for grounding connection). It may cause corrosion of the
frame or compromise the framework strength.
11. Do not touch the PV module with bare hands. The frame
of PV module has sharp edges and may cause injury.
12. Do not drop PV module or allow objects to fall down on
the PV module.
13. Do not concentrate sunlight articially on the PV module.
14. Do not hold the PV module on one side. The frame may
bend or twist. Hold the PV module at opposite sides.
15. Do not touch the anti-reective coated glass since nger
prints and/or stains can be easily left on the glass surface.
INSTALLATION SAFETY
1. Always wear protective head gear, insulating gloves and
safety shoes (with rubber soles). Do not wear metallic
jewellery to prevent electric shock during installation.
2. Keep the PV module packed in the carton until
installation.
3. Do not touch the PV module unnecessarily during
installation. The glass surface and the frames get hot.
There is a risk of burn, or electric shock.
4. Do not work under rain, snow or windy conditions.
5. Use dry insulated tools.
6. Do not drop tools or hard objects on PV modules
7. When working at heights, wear a safety belt and take
care not to drop any items (e.g., PV module or tools).
8. Make sure ammable gases are not generated near the
installation site.
9. Completely cover the PV module surface with an opaque
material during PV module installation and wiring.
10. Plug in the connector tight and ensure the wiring work.
Make sure that the connectors have been locked by a
snap-in latch. Any treatments over the connectors which
may allow to unlock the snap-in latch shall not be done.
11. Due to the risk of electrical shock, do not perform any
work if the terminals of PV module are wet.
12. Do not touch the junction box and the end of output
cables, the cable ends (connectors) , with bare hands
during installation or under sunlight, regardless of
whether the PV module is connected to or disconnected
from the system.
13. Do not unplug the connector if the system circuit is
connected to a load.
14. Do not stomp on the glass at work. There is a risk of
injury or electric shock if glass is broken.
15. Do not work alone (always work as a team of 2 or more
people).
16. Do not damage the back sheet of PV modules when
setting the equipotential bonding by bolts.

17. Do not damage the surrounding PV modules or mounting
structure when replacing a PV module.
18. Bind cables by the insulation locks. Drooping down of
cables from the junction box could possibly cause various
problems such as animal biting, electricity leakage in
puddle.
19. Take proper measures for preventing the laminate
(consisted of resin, cells, glass, back sheet, etc.) from
dropping out of the frame in case the glass is broken.
20. Cables shall be located so that they will not be exposed
to direct sunlight after installation to prevent degradation
of cables.
21. If batteries are used with modules, follow safety
precautions of the battery manufacturer.
22. In case of extreme snow build-up, the weight of the snow
may cause the module’s frame to deform. Take
appropriate preventive measures to minimize any
possible resulting damage.
4. SITE SELECTION
In most applications, the PV modules should be installed in a
location where there is no shading throughout the year. In the
Northern Hemisphere, the PV modules should typically face
south, and in the Southern Hemisphere, the PV modules
should typically face north.
Please make sure that there are no obstructions in the
surroundings of the site of installation. TAKE PROPER
STEPS in order to maintain reliability and safety, in case the
PV modules are used in areas such as: Heavy snow areas /
Extremely cold areas / Strong wind areas / Installations over,
or near, water / Areas where installations are prone to salt
water damage/corrosive gas environment/ Small islands or
desert areas.
The results of the ammonia test and the salt-mist-corrosion
test on the modules, carried out under such strict test
conditions, should be disclosed for reference purposes only.
The decision on whether the modules are suitable and
compatible for each installation eld will depend on the user’s
judgement and responsibility.
5. TILT ANGLE
The tilt angle is the measurement between the PV module
and a horizontal ground surface. The PV module generates
the maximum output power when it faces the sun directly.
5 degrees or more is recommended for the tilt angle of the PV
module for the maintenance. (See 9. Maintenance)
For the standalone systems with a battery where the PV
modules are attached to a permanent structure, the tilt angle
of the PV modules should be determined to optimize the
performance when the sunlight is the scarcest. In general, if
the electric power generation is adequate when the sunlight is
the scarcest, then the angle chosen should be adequate
during the rest of the year. For grid-connected installations
where the PV modules are attached to a permanent structure,
it is recommended to tilt the PV module at the angle equal to
the latitude of the installation site so that the power generation
from the PV module will be optimum throughout the year.
6. WIRING
To ensure proper system operation and to maintain your
guaranty, observe the correct cable connection polarity
(Figures 1) when connecting the modules to a battery or to
other modules. If not connected correctly, the bypass diode
could be destroyed.
PV modules can be wired in series to increase voltage.
Connect wires from the positive terminal of one module to the
negative terminal of the next module. Figure 1 shows modules
connected in series.
7. GROUNDING
The frame grounding must consider the local requirement
and regulation at the installation site. When grounding is
required, please refer to below example connection (Figure 3).
Please be careful in arranging the system ground so that the
removal of one module from the circuit will not interrupt the
grounding of any other modules.
The modules should be grounded to the same electrical point
as described below.
You can use a hole with the appropriate symbol for
equipotential bonding on the side frame for either a bolt, nut
and washer grounding the module to the frame, a ground lug
fastened by bolt or screw, or appropriate screw (hardware not
provided). An example of acceptable ground connection using
a bolt, nut and washer retaining a ground lug is shown in
gure 3. In a connection of this type, the hardware (such as a
toothed locked washer / star washer) must score the frame
surface to make positive electrical contact with the frame. The
ground wire must be considered within the local requirement
of local and regulation at the site of installation.
8. MOUNTING
Please make sure that all the information described in the
installation manual is still valid and proper for your installation.
The mounting method has been veried by SHARP and NOT
CERTIFIED by a third party organization.
The approved way to mount Sharp PV modules to a support
structure is described in this INSTALLATION MANUAL.
Although Sharp does not specify or warrant frame clips or
clamps, using frame clips (not provided) or clamps (not
provided) is possible when they are designed for PV modules
and with minimum dimensions on the sides of the module in
accordance with the instructions and drawings provided. If
using frame clips or clamps, the modules should bexed
rigidly and there shall be no damage to the modules by
deforming mounting structure against design load.
The Sharp module guaranty may be void if customer-
selected frame clips are improper or inadequate for module
properties (including strength or material) or installation. Note
that if metal clips are used, there must be a path to ground
from the clips, (for instance, using star washers in the clip
hardware set).
Please review the descriptions and drawings carefully; not
mounting the modules according to one of these methods may
void your guaranty. These mounting methods are designed to
allow module loading of 2400Pa. Support structures that PV
modules are mounted on should be rigid. Sharp PV modules
are designed to ensure optimal electrical performance under
the condition that they are mounted on rigid support structures.
Deformation of support structure may damage PV module with
its electric performance.
When mounting the module on structure, ensure that no
corner has a displacement of more than 2mm per every
1000mm of the diagonal.
9. MAINTENANCE
The modules are designed for long life and require very little
maintenance. If the angle of the PV module is 5 degrees or
more, normal rainfall is sucient to keep the module glass
surface clean under most weather conditions. If dirt build-up
becomes excessive, clean the glass surface preferably with
water only, or with wet soft sponge or cloth in case to remove
stubborn dirt. If cleaning the back of the module is required,
take utmost care not to damage the back side materials. In
order to ensure the operation of the system, check the
connection of wiring and the state of the jacket of wires
occasionally.
