5. SITE SELECTION AND WORK ENVIRONMENT
☆
In most applications, the PV modules should be installed in a location
where there is no shading
throughout the year. 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 EGING local agent first to determine an
appropriate installation method, or to
determine whether the installation is
possible.
☆
EGING PV modules have also passed salt mist corrosion test according to IEC60701. But
corrosion may occur in the module frame connecting to the bracket portion or the portion of ground
connection. those parts shall be prepared with anti-corrosion treatment before usage.
☆
Make sure flammable gases are not generated near the installation site.
☆
EGING PV modules have passed the tests in IEC61215 and IEC61730, including damp heat test,
wet leakage current test and so on. The protection level of EGING PV modules is IP65. The PV
modules should not be installed in flooded areas. The junction box should be on the higher side of
the module when it is mounted.
☆
EGING recommend that the PV modules should be installed in the place where the operating
temperature is from -20
℃
to 46
℃
. The operating temperature is the maximum and minimum
monthly average temperature of the installation site. The limit of working temperature is from -40
℃
to 85
℃
.
☆
EGING PV modules can be used on proper structure or any other place which is suitable for
module installation(such as ground, roof and façade).
6. TILT ANGLE
☆
The tilt angle of the PV module is the angle between the PV
module and a horizontal ground
surface. The PV module generates the
maximum output power when it faces the sun directly.
☆
In the Northern
Hemisphere, the PV modules should typically face south, and in the
Southern
Hemisphere, the PV modules should typically face north.
☆
For the standalone systems with a battery where the PV modules are
attached to a permanent
structure, the tilt angle of the PV modules
should be determined to optimize the performance
when the sunlight is
the scarcest. In general, if the electric power generation is adequate when the
sunlight is the scarcest, then the angle chosen should be adequate during the rest of the year. For
grid-connected installations where the PV modules are attached to a permanent structure, 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.
☆
For the detailed installation angle, which is different in different area, may refer to the
recommendation of the experienced PV modules installation supplier.
7. WIRING
☆
To ensure proper system operation and to maintain your warranty, observe the correct cable
connection polarity (Figures 2 & 3) when connecting the modules to a battery or to other modules.
