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.

CAUTION: HIGH VOLTAGE

To reduce the risk of electric shock, do not touch.

SIM424-003

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.

SIM424-003

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 be xed

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.
