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, specifications or installation manual without
prior notice.

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 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 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 are 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.
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 off 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.

Consult local codes and other applicable laws
concerning required permits on regulations for
installation and inspection requirements.
Before installing a PV module, contact appropriate
authorities to determine permit, installation and
inspection requirements that should be followed.
Install PV modules and ground frames in accordance
with applicable rules and regulations.
PV modules should be installed and maintained by
qualified personnel. Only installer/servicer personnel
should have access to the PV module installation site.
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.
In the case that the PV modules are non-integral type,
the module is to be mounted over a fire resistant roof.
Use PV modules with the same cell size within series.
Follow all safety precautions of other components that
are used in the system.
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.
the sunlight for a long time. The shaded cell may
become hot (hot spot phenomenon) which results in
solder joints peeling off. Shading causes drop in
generated power and/or operation failure of the PV
modules.
let water collect on the glass surface for a long time.
This creates a risk of white efflorescence (glass
disease) which may result in the deterioration of energy
generation.

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.
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.
Do not cause an excessive load on the surface of PV
module or twist the frame. The glass surface can easily
break.
Do not stand or step on the PV module. The surface
glass of PV module is slippery.
Do not hit or put excessive load on the glass or back
sheet. The PV cell is very thin and can be easily broken.
Do not scratch or hit at the back sheet. The back sheet is
vulnerable.
Do not damage the junction box or do not pull the cables.
The junction box can crack and break.
Never touch junction box or the end of output cables with
