GENERAL INSTALLATION MANUAL
FOR SHARP PV MODULES
PLEASE READ THIS MANUAL CAREFULLY BEFORE INSTALLING OR USING THE MODULES. INSTALLERS SHOULD PROVIDE THIS MANUAL TO YOUR CUSTOMER.
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 is 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.
2. 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 and appropriately 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. SHARP PV modules are either equipped with a permanently attached junction terminal box that will accept a variety of wiring applications or equipped with a pre-terminated cable assembly for ease of installation.
< 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 module 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. PV systems 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 loads such as motors since the variable output power of the PV modules (dependent on solar irradiation) may cause damage to the connected motor.
< 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.For PV modules that are non-integral type, the modules are to be mounted over a fire-resistant roof.
7.PV modules connected in series should have the same cell size.
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 about PV modules or 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. Shaded cells may become hot (hot spot phenomenon) which may result in permanent damage, e.g., 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 reduced energy generation.
12.Do not install the PV module horizontally. It may cause dirt or white efflorescence (glass disease) due to water. A minimum tilt of 5 degrees from the horizontal is required; a tilt of 10 degrees or more is recommended (a higher tilt angle will contribute to cleaning the surface during rainstorms).
13.Do not cover the water drain holes of the frame. There is a risk of frost damage when the frame has water in it.
14.When sliding snow load has to be considered, an appropriate measure must be taken so that the lower edge of the PV module frame will not be damaged.
15.Do not expose PV modules to sunlight concentrated with mirrors, lenses or similar means.
16.Should a problem occur, immediately turn off inverters and circuit breakers.
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 prior to removing the module.
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, when considering the effect of temperature, must not be greater than the specified maximum system voltage. Voltage is proportional to the number of PV modules in 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 reverse current flow; otherwise, current may easily flow in reverse.
< 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 the back sheet. The back sheet is vulnerable.
5.Do not hit the terminal box; do not pull the cables. The terminal box can crack and break.
6.Never touch the terminal box or the ends of output cables with bare hands when the PV module is illuminated. During handling and installation, cover the surface of PV module with cloth or other suitable sufficiently opaque material to shield 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 cable insulation can break and may result in electricity leakage or shock.
8.Do not pull the output cable excessively. The output cable may come undone 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 coating of the frame (except for grounding connection). It may cause corrosion of the frame or compromise the frame strength.
11.Do not loosen or remove the screws in the frame. It may compromise the strength of PV module and cause corrosion.
12.Do not handle the PV module with bare hands. The frame 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 artificially concentrate sunlight on the PV module.
15.Do not lift the PV module by only one side. The frame may bend. Lift the PV module by holding two (opposite) sides.
< INSTALLATION SAFETY >
1.Always wear protective head gear, insulating gloves and safety shoes (with rubber soles).
2.If the PV modules are delivered in cartons, keep them packed in the cartons until installation.
3.Do not touch the PV module unnecessarily during installation. The glass surface and the frames may become hot. There is a risk of burn, or 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.For modules with connectors, ensure connections are fully plugged together.
12.Due to the risk of electrical shock, do not perform any work if the terminals of PV module are wet.
13.Do not touch the terminal box or 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.
14.Do not unplug the connectors if the system circuit is connected to a load. The connectors are not rated for load-break.
15.Do not stand or stomp on the glass. 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 jewelry 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 structure.
20.Do not damage the surrounding PV modules or mounting structure when replacing a PV module.
21.Use UV rated cable ties or other methods to cinch loose cables. Drooping cables could cause various problems such as facilitating damages by animals or electricity leakage (from cables lying in puddles).
22.Take proper measures for preventing the laminate (consisting of 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.
24. Do not put anything (e.g. tools, clothes, etc.) on the modules
