GENERAL INSTALLATION MANUAL FOR SHARP PV MODULES
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 warranty, 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, specifications or installation manual without prior notice.
GENERAL INFORMATION (INCLUDING WARNING AND SAFETY)
The installation of PV modules requires a great degree of skill and should only be performed by a qualified 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 terminal 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 is
connected or not.
4. PV modules produce electricity when the sufficient 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.
General Safety
1. Consult local codes and other applicable laws concerning required permits on regulations concerning 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 qualified 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 fireproofing, depending on local building/fire codes.
6. In the case that the PV modules are non-integral type, the module is to be mounted over a fire resistant roof.
7. Please use PV modules with same cell size within series.
8. Follow all safety precautions of other components 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 off.
11. Do not clean the glass surface with chemicals. Do not let water stay on the glass surface of PV modules for a long time. This creates a risk of
white efflorescence (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 efflorescence (glass disease) due to water cumulation.
13. Do not cover the water drain holes of the frame. There is a risk of frost damage when the frame is filled with water.
14. When sliding snow load has to be considered, 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 off 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 specified 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.
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 hit on the terminal box or do not pull the cables. The terminal box can crack and break.
6. Never touch terminal 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 sufficiently opaque material to isolate the PV module from incident light and handle the wires with rubber-gloved hands 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 of the frame.
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 loosen or remove the screws of the PV module. It may compromise the joint strength of PV module and cause corrosion.
12. Do not touch the PV module with bare hands. The frame of PV module has sharp edges and may cause injury.
13. Do not drop PV module or allow objects to fall down on the PV module.
14. Do not try artificially to concentrate sunlight on the PV module.
15. Do not grab the PV module at only one side. The frame may bend. Grab the PV module at two sides facing each other.
Installation Safety
1. Always wear protective head gear, insulating gloves and safety shoes (with rubber soles).
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 you may collapse because of electric shock.
4. Do not work under rain, snow or windy conditions.
5. Use insulated tools.
6. Do not use wet tools.
7. Do not drop tools or hard objects on PV modules.
8. When installing PV modules far above ground, do not drop any object (e.g., PV module or tools).
9. Make sure flammable gases are not generated near the installation site.
10. Completely cover the PV module surface with an opaque material during PV module installation and wiring.
11. Plug in the connector tight and ensure the wiring works.
12. Due to the risk of electrical shock, do not perform any work if the terminals of PV module are wet.
1
3. Do not touch the terminal box and the end of output cables (connectors) with bare hands during installation or under sunlight, regardless of
whether the PV module is connected to or disconnected from the system.
14. Do not unplug the connector if the system circuit is connected to a load.
15. Do not stand on the glass at work. There is a risk of injury or electric shock if glass is broken.
16. Do not work alone (always work as a team of 2 or more people).
17. Wear a safety belt if working far above the ground.
18. Do not wear metallic jewellery which can cause electric shock during installation.
19. Do not damage the back sheet of PV modules when fastening the PV modules to a support by bolts.
20. Do not damage the surrounding PV modules or mounting structure when replacing a PV module.
2
1. Bind cables by the insulation locks. Drooping down of cables from the terminal box could possibly cause various problems such as animal biting,
and electricity leakage in puddle.
22. Take proper measures for preventing the laminate (consisting of resin, cells, glass, back sheet, etc.) from dropping out of the frame in case the
glass is broken.
23. Cables shall be located so that they will not be exposed to direct sunlight after installation to prevent degradation of cables.
COMPONENTS 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(*) / Small islands or desert areas.
(*) If you are planning to use the PV modules where the salt water damage may be possible, please consult with
SHARP local agent first to determine an appropriate installation method, or to determine whether the installation is
possible.
TILT ANGLE
The tilt angle of the PV module is measured between the PV module and a horizontal ground surface . The PV module generates the maximum output
power when it faces the sun directly. 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.
WIRING
To ensure proper system operation and to maintain your warranty, 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 connected in parallel.
INSTALLATION ELECTRICAL RATING
Refer to installation manual of individual models of PV module. Refer to installation manual of individual models of PV module.
GROUNDING
All PV modules must be grounded by electrical connection of the module frames to ground. 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. Each PV module
has a hole 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 figure 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 requirement of local regulations at the site of installation.
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 verified by SHARP and NOT CERTIFIED by a third party organization. The approved way to mount Sharp PV modules to a support structure is
using the bolt holes provided as described in the Specifications. Although Sharp does not specify or warrant frame clips or clamps, using frame clips
(not provided) or clamps (not provided) is also 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 fixed rigidly and there shall
be no damage to the modules by deforming mounting structure against design load. Sharp does not specify or warrant frame clips. The Sharp module
warranty may be void if customer-selected frame clips which are improper or inadequate with respect to the 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
warranty. 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 secure their electric performance under the condition that they are mounted on rigid support structures. Deformation of support structure may damage PV module with its electric performance.
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 sufficient to keep the module glass surface clean under most weather conditions. If dirt build-up becomes excessive, clean the glass surface only with a
soft cloth using water. 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, please check the connection of wiring and the state of the jacket of wires every now and then.
