IMPORTANT SAFETY INSTRUCTIONS
PLEASE READ THIS MANUAL CAREFULLY BEFORE INSTALLING OR USING THE MODULES.
PLEASE PASS ALONG THIS MANUAL TO YOUR CUSTOMER.
A) GENERAL MANUAL
A-1. INTRODUCTION
< GENERAL SAFETY >
1. Wiring and grounding method of the frame of arrays shall comply with
national, regional and local codes, laws and standards.
2. PV modules should be installed and maintained by qualified personnel.
Only installation/service personnel should have access to the PV
module installation site.
Thank you for choosing SHARP photovoltaic (PV) module. This
Installation Manual contains essential information for electrical and
mechanical installation that you must know before installing SHARP
photovoltaic modules. These modules are listed to standard UL 1703.
This Manual also contains safety information you need to be familiar with.
All the information described in this Manual is the intellectual property of
SHARP and is based on the technologies and experience that have been
acquired and accumulated over the long history of SHARP. This Manual
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 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 modules. SHARP reserves the right to make
changes to the product, specifications or Installation Manual without prior
notice.
3. Keep children away from PV modules.
4. Prior to installation, do not store modules outdoors or in a damp
environment to prevent glass from damage due to white efflorescence.
5. When PV modules are installed on roofs or any other structures
above ground, appropriate safety practices should be followed
and appropriate safety equipment should be used in order to avoid
possible safety hazards. Note that the installation of PV modules on
some roof types may require the addition of fireproofing, as required
by local building/fire codes.
6. Roof mounted PV modules are to be mounted over a fire resistant roof.
7. Only PV modules with the same cell size should be connected in series.
8. Follow all safety precautions of other components used in the system.
9. In order to avoid risk of injury or electrical shock, do not allow anyone
to handle damaged PV modules if the person is unqualified or has
limited knowledge of PV modules. Place defective PV modules in
cartons so PV cells are completely shaded, because a defective PV
module or module with broken glass may generate power even if it is
removed from the system.
A-2. GENERAL INFORMATION
(INCLUDING WARNING AND SAFETY)
The installation of PV modules requires a great degree of skill and should
only be performed by qualified licensed professionals, 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. These SHARP PV modules are equipped with a
permanently attached special cable assembly for ease of installation which
does not require special assembly.
10.Avoid uneven shade on the PV module surface. Shaded cells may
become hot (“hot spot” phenomenon) which may result in permanent
damage to the module (e.g., solder joints may peel off).
11. Do not clean the glass surface with chemicals. Do not let water stay on
the glass surfaces of PV modules for a long time. This creates a risk of
permanent damage to the glass, such as white efflorescence, otherwise
known as “glass disease,” which may cause reduced power output.
12.To avoid dirt accumulation or white efflorescence due to water
accumulation, do not install PV modules horizontally (flat).
13.In case of snow build up, snow would be slide down easier on the
module than other parts of the roof. When snow suddenly slide and
fall off the module’s surface, it may fall to under the roof and reach
nearby areas. Ensure that the installment of the modules would not
cause any damage to objects (carport, bicycle, entrance) nearby.
Apply appropriate safety measures and/or safety equipments (e.g.
snow stopper) when necessary.
< 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 sufficient sunlight or other
light source illuminates the module. When modules are connected
in series, voltage is cumulative. When 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 PV modules directly to motor loads. Variation in PV
module output power as a function of solar irradiance may damage
directly-connected loads. For example,
1: In the case of a brushless motor, the lock function may become
active and the motor may be damaged;
2: In the case of a brush type motor, the coil may be damaged.
6. Always use gloves when handling the module, never touch the glass
surface with bare hands.
14.Do not expose PV modules to sunlight concentrated with mirrors,
lenses or other means.
15.Turn off inverters and circuit breakers immediately, should a problem occur.
16.The maximum open circuit voltage must not be greater than the
specified maximum system voltage. Voltage is proportional to the
number of PV modules in series and is affected by weather conditions.
For strings connected in parallel take proper measures to block
reverse current flow.

Installation Manual for PV Modules
Ver. 6.0U _ Sep 6, 2012
SERIES WIRING (VOLTAGE ADDITIVE)
For grounding, each PV module has a hole in the frame for either a bolt,
nut and washer, a ground lug fastened by bolt or screw, or an appropriate
screw (hardware not provided). Installation for wiring and grounding
method shall be in accordance with national, regional and local codes,
laws, standard, and the relevant instructions below. In a connection of this
type, the hardware (such as a star washer) must score the frame surface
to make positive electrical contact with the frame. The ground wire must
not be smaller than No.12 AWG.
PARALLEL WIRING (CURRENT ADDITIVE)
The National Electrical Code (NEC) 690.33 requires that connectors are
installed in a readily accessible location, circuits operating at over 30
volts, shall require a tool to open. PV module’s connectors comply with
the NEC corresponding section.

of the wire (the wire slot will cause the wire to form a slight curve).
The grounding conductor wire should be sized according to national,
regional and local codes, laws, and standards. Note that the TYCO
SolKlip 1954381-2 only accepts wire sizes 10 -12 AWG.
4. Manually, or using channel lock pliers, push the slider over the base
until it covers the base. This will terminate the wire.
Please contact “Tyco electronics corp.” about detail information of
“1954381-2”
A-6. MAINTENANCE
SHARP PV 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 usually sufficient to keep the module glass surface clean under
most weather conditions. Do not touch the glass since finger prints or
stains will easily mark the glass. For AR coating - Sharp modules utilize
special materials to increase energy harvest. Always use gloves when
handling the module, never touch the glass with bare hands. If dirt build-
up becomes excessive, clean the glass surface with water only. If cleaning
the back of the module is required, take utmost care not to damage the
back side materials. In order to ensure proper operation of the system,
please check all wiring connections and the condition of the wire insulation
periodically.

B) MODULE SPECIFIC INSTRUCTIONS
Mounting Using Clamps on Long Edge of Module: Long Edge
Perpendicular to Array Rails (Figures 5 & 9)
MECHANICAL INSTALLATION
There are several approved ways to mount these Sharp PV modules to
a support structure. They may be mounted either using the bolt holes
provided or using frame clamps (not provided). Inter-module type or
end-type clamps must be designed for PV modules and have minimum
dimensions shown in Figure 4 & 5 and listed in Table I on the long sides
of the module in accordance with the instructions below and drawings
provided. To avoid shading and module damage, the clamp should be
within frame coverage width. Further, the clamp should not extend higher
than the level defined by an imaginary line drawn at 24 degrees from
the module glass outward from the intersection of the frame and glass.
Clamps should be made of aluminum, stainless steel or other appropriate
material to resist weathering and galvanic corrosion. Sharp does not
warranty frame clamps or take responsibility for any third party mounting
system. Sharp does not warranty frame clamps. The Sharp module
warranty may be void if customer-selected frame clamps or third party
mounting system are improper or inadequate with respect to properties
(including strength or material) or installation. Note that if metal clamps
are used, there must be a path to ground from the clamps, (for instance,
by using star washers in the hardware set). Please review the descriptions
below and drawings carefully; not mounting the modules according to one
of these methods may void your warranty. Additionally, UL has tested and
listed these modules for mounting using either bolts or clamps. Mounting
with clamps is considered to be equivalent to mounting with bolts and is
acceptable under the same conditions as bolt mounting.
The modules may also be mounted using clamps on the long sides of
the module when the array rails are perpendicular to the long sides, as
shown in Figure 5 and listed in Table I. The clamp centerlines must be
between 5.9” (150 mm) and 16.1” (410 mm) regarding ND/NU series as
shown in Figure 9 from the ends of the module. Note that the mounting
clamps should meet the minimum dimensions as shown in Figure 5 and
listed in Table I. The array rails must support the bottom of the modules
and clamps, also must be continuous pieces (no un-spliced breaks in the
rail). This mounting method is designed to a static load rating of 2400 Pa
(50.1 lbs/ft²).
To provide adequate ventilation, modules must be mounted such that
there is a minimum 50 mm gap between the bottom of the module frame
and the roof deck/ground surface.
Rail parallel with long side of module
Figure 4
Mounting Using Frame Bolt Holes (Figures 6)
The modules may be fastened to a support utilizing the four 9 mm
diameter holes in the bottom of the frame and according to Figure 6. The
module should be fastened with four (4) M8 (5/16") bolts. Recommended
torque value is 12.5 Nm. This mounting method is designed to a static
load of 2400 Pa (50.1 lbs/ft²). For your reference, please use the washer
specified as below for the minimum requirement:
We recommended parts of the following specifications.

Mounting Using Clamps on Long Edge of Module: Long Edge Parallel
to Array Rails (Figures 4 & 8)
Figure 5
The modules may be mounted using clamps designed for solar modules
as shown in Figure 4 and Table I. Note that the clamp positions are
important – the clamp centerlines must be between 5.9” (150 mm) and
16.1” (410 mm) regarding ND/NU series as shown in Figure 8 from the
end of the module. The module must be supported along the length of the
long edge, and should overlap the array rail by at least 0.4” (10 mm). Note
that the mounting clamps should meet the minimum dimensions as shown
in Figure 4 and listed in Table I. The array rails must support the bottom
of the modules and must be a continuous piece (no un-spliced breaks in
the rail). This mounting method is designed to a static load rating of 2400
Pa (50.1 lbs/ft²).

Mounting using Clamps on Long Edge of Module (Figure 7) – 2 Clamp Method
The modules may be mounted using clamps designed for solar modules as shown in Figure 7. Note the clamp position is important. The 22” length clamp
should be positioned so that it supports the center of each long frame of the solar module. The clamp should be affixed to the modules and mounting
structure with 4 bolts on each long frame. For the 2 clamp mount method, the minimum clamp length dimension is 22”. The modules should be inserted fully
into the module clamps so that the outside edge of the module frame is flush with the inside surface of the clamp. The clamp is designed to overhang the
top module edge by 12mm. This mounting method is designed to allow module loading of 1,440 Pa.
