INSTALLATION MANUAL AND USER MANUAL
FOR SHARP PHOTOVOLTAIC MODULES
PLEASE READ THIS MANUAL CAREFULLY BEFORE INSTALLING OR USING THE MODULES.
A-1. INTRODUCTION
This Installation Manual contains essential information for electrical
and mechanical installation that you must know before installing
SHARP photovoltaic (PV) modules. These modules are UL listed (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.
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 junction box for
ease of installation of wires and conduit.
< 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.
< GENERAL SAFETY >
1. Consult local codes and applicable laws concerning required
permits and regulations concerning installation and inspection
requirements.

A) GENERAL MANUAL
2. Install PV modules and ground frames and other metal
components in accordance with applicable codes and regulations.
3. PV modules should be installed and maintained by qualified
personnel. Only installation/service personnel should have access
to the PV module installation site.
4. 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.
5. Roof mounted PV modules are to be mounted over a fire resistant
roof.
6. Only PV modules with the same cell size should be connected in
series.
7. Follow all safety precautions of other components used in the
system.
8. 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.
9. 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).
10. 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.
11. To avoid dirt accumulation or white efflorescence due to water
accumulation, do not install PV modules horizontally (flat).
12. Do not cover the water drain holes of the frame. There is a risk of
frost damage when the frame is filled with water.
13. In high snow load regions, appropriate measures are to be taken
so that PV module frames (on lower edges of the modules) will not
be damaged.
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. A defective PV module or module with broken glass may generate
power even if it is removed from the system. It may be dangerous
to handle the defective PV module while exposed to sunlight. Place
defective PV modules in cartons so PV cells are completely
shaded.
17. 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.
18. Keep children away from PV modules.
