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.

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 connected or not. are
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 installation and for
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 reproong, 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 are resistant roof.
7. e PV modules with Us 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. gap Do not cover the water drain 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 flow. The current may easily flow in a
reverse direction.
20. p modules away from children. Kee
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. damage Do not 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. the PV module. Do not concentrate sunlight artificially on
14. Do not hold the PV module one side. The frame may on
bend or twist Hold the PV module at opposite sides. .
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. e Plastic components such as cables or connectors shall b
located so that they will not be exposed to direct sunlight
after installation to prevent degradation of them.

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 field 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 ( 9. Maintenance). See
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 & 2) 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.
Connect PV modules in parallel to increase current. Connect
wires from the positive terminal of one module to the positive
terminal on the next module. Figure 2 shows modules
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
You can use hole with the appropriate symbol for a
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.
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 be xed rigidly and
there shall be no damage to the modules rming by defo
mounting structure against design l oad.
T Sharp module guaranty may be void if customer-selectedhe
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. 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, use only a soft, damp cloth and water to clean the
glass. 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.
For PV modules with anti-reective coating glass, do not touch
the glass since nger prints or stains will easily mark. If dirt build-
up becomes excessive, clean the glass surface with water only.
