Site Selection; Tilt Angle; Installation Safety - Sharp NA-E115L5 Installation Manual

17. 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.
18. 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.
19. Do not keep PV modules without grounded by minus-pole.
< HANDLING SAFETY >
1. Do not cause an excessive load on the surface of PV module. The
glass surface can easily break.
2. Do not stand or step on the PV module.
3. Do not hit or put excessive load on the glass. The PV module can
be easily broken.
4. Do not hit on the terminal box or do not pull the cables. The
terminal box can crack and break.
5. 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.
6. 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. Ensure that the bend radius of the connection cables is kept
greater than 60 mm at all times.
7. Do not pull the output cable excessively. The output cable may
unplug and cause electricity leakage or shock.
8. Do not drop PV module or allow objects to fall down on the PV
module.
9. Do not try artificially to concentrate sunlight on the PV module.
< INSTALLATION SAFETY >
1. Always wear protective head gear, insulating gloves and safety
shoes (with rubber soles).
2. Keep the PV module packed until installation.
3. Always store the PV modules securely in a dry place. The
packaging is not weather-resistant.
4. Do not touch the PV module unnecessarily during installation. The
glass surface get hot. There is a risk of burn, or you may collapse
because of electric shock.
5. Do not work under rain, snow or windy conditions.
6. Use insulated tools.
7. Do not use wet tools.
8. Do not drop tools or hard objects on PV modules
9. When installing PV modules far above ground, do not drop any
object (e.g., PV module or tools).
10. Make sure flammable gases are not generated near the installation
site.
11. Completely cover the PV module surface with an opaque material
during PV module installation and wiring.
12. Plug in the connector tight and ensure the wiring work.
13. Due to the risk of electrical shock, do not perform any work if the
terminals of PV module are wet.
14. Do not touch the terminal box and the end of output cables 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.
15. Do not unplug the connector if the system circuit is connected to a
load.
16. Do not stomp on the glass at work. There is a risk of injury or
electric shock if glass is broken.
17. Do not work alone (always work 2 or more people).
18. Wear a safety belt if working far above the ground.
19. Do not wear metallic jewelry which can cause electric shock during
installation.
20. Do not damage the surrounding PV modules or mounting structure
when replacing a PV module.
21. Bind cables by the insulation locks. Drooping down of cables from
the terminal box could possibly cause various problems such as
animal biting, electricity leakage in puddle.
22. Cables shall be located so that they will not be exposed to direct
sunlight after installation to prevent degradation of cables.
23. Do not shade any portion of the module during installation as this
will cause heating (e.g. tools, clothes, etc.)

4. 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.

5. TILT ANGLE

The tilt angle of the PV module is the measured between the PV
module and a horizontal ground surface. The PV module generates the
maximum output power when it faces the sun directly.
The tilt angle of the PV modules should be determined to optimize the
performance. 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. The tilt angle
of PV modules should be not less than 5 degree.
The modules shall be mounted so that minimum 100 mm clearance
between the module and the support surface shall be maintained to
assure the ventilation of the modules.
