From the 10th to the 14th digits: CCCCC means the serial number of production.
6. Matters needing attention for unpacking
As for outdoors unpacking, it is prohibited to operate in rainy conditions. Because the carton will
become soft and damaged after it gets wet in the rain. The PV modules (hereinafter referred to as
"modules") inside the carton will incline, which may cause damage or injury to personnel.
If there is wind at site, it is necessary to pay special attention to safety, especially in strong wind
conditions, and it is NOT recommended to transport the modules at this situation. The unpacked modules
shall be fixed properly.
The ground should be flat where unpack the packaging, this will ensure that the carton can be placed
stably and to avoid incline.
Wear protective gloves during unpacking to avoid hand injury and finger prints on the glass surface.
Module information and unpacking instructions can be found on the outer package. Please read the
instructions before unpacking.
Each module shall be handled by two personnel. It is forbidden to pull the wires or junction boxes of
the modules to carry the module.
In addition to the above points for attention, consider professional on-site unpacking, exception
handling rules, please refer to RISEN Packaging Manual.
7. Installation
7.1. Environment conditions and site selection

15
RS/03-GT-016-2019 Date: 2021-02-01
Risen module should be installed in the following environmental conditions.
Table 7-1 operation condition

4
Humidity
＜85 RH%
Remarks: The working environment temperature is the monthly average maximum temperature and
minimum temperature of the installation site. The mechanical load bearing capacity of the solar PV
module is determined based on the installation method. The professional solar PV system installer
must be responsible for calculating the solar PV system machinery when designing the solar PV
system load bearing capacity.
If the module will be installed in a place of which the humidity is more than 85RH%, please get contact
with Risen After-service team ([e-mail]) for the properly installation method, or
check whether the module can be installed or not.
For most places, Risen solar PV modules should be installed where the sunlight can be maximally
acquired throughout the year. In the Northern hemisphere, the light-receiving surface of the module is
usually selected to face the South; in the Southern hemisphere, the light-receiving surface of the
module is usually selected to face the North.
When selecting the installation location, avoid areas with trees, buildings, or obstacles because these
objects will form shadows on solar PV modules, especially when the sun is at the lowest position on the
horizon in winter. The shadow will cause the loss of the output power of the solar photovoltaic system.
Although the bypass diode installed in the solar photovoltaic module can reduce this loss to some
extent, do not ignore the shadow factor.
Do not install solar PV modules near fire or flammable materials. Do not install solar PV modules where
there is water soaking, sprinkler or water spray.
Risen Anti-salt mist PV modules have passed the IEC61701 salt mist method 6 test. On land more than
1KM away from the coastline, Risen Anti-salt mist PV modules can be installed; Risen salt spray

16
RS/03-GT-016-2019 Date: 2021-02-01
resistant PV modules have passed the IEC61701 salt mist method 8 test, which is currently recognized
as the most stringent test method. On land and offshore seas that are less than 1Km from the coastline,
Risen recommends installation of salt spray resistant modules that pass the IEC61701 salt spray 8 test
7.2. Tilt angle of Installation
The installation of solar PV module string should be in the same orientation and the same installation
angle. Different installation directions and installation angles will lead to the mismatches in current and
voltage which is caused by different light absorption of different solar modules, this mismatch will cause
the PV system power output loss.
The largest power will be generated When direct sunlight on solar PV module. For modules which are
installed on the fixed brackets, the best installation angle should be selected to ensure the maximum
power output can be generated at winter time, if the angle can guarantee enough power output during
the winter, it will make the whole solar PV system in the rest of the year can have enough power output
also.
Installation inclination refers to the Angle between the solar photovoltaic module and the ground plane,
as shown in Figure 7-1.

7.3. Installation requirements for bifacial module
Under the certain installation conditions, the backside of bifacial dual glass module will also generate
electricity power after receiving the reflected light, which will bring additional power generation gain to
the power station system.
The shading on the module surface will affect the power generation much, the module should be
installed in the place where the module cannot be shadowed totally (such as the shadow from building,
chimney and tree etc.), and even the partially shading (such as the dirt, snow and aerial wire etc.)
should be avoided.
The generation gain is related to the ground reflectivity, the module installation height to the ground, the
array spacing and the shadow shading to the module backside.
Generally speaking, the reflectance is various with the different ground (See table 7-3), and this will
lead to different power generation gain.

Due to the different ground clearance height will affect the power generation gain, it is recommended to
install the module at a height from 0.5m to 2m. See Fig. 7-2.

RS/03-GT-016-2019 Date: 2021-02-01
Fig. 7-2 Distance from the earth
When designing the system, in addition to the type of ground and the height above the ground, the
appropriate array spacing and how to avoid the back shadow should be considered. Please refer to 《Risen
bifacial module PV system design white paper》, or consult professional system designers.
8. Installation Guidelines
Ensure that the support system is strong enough and the components must be fixed to the support
system as required；
The limit load of the support system must be calculated according to the project site conditions,
installation methods, etc. and the local specifications. The support system supplier must be
responsible for the design, verification, installation and maintenance of the photovoltaic system；
In order to reduce the adaptation loss, please ensure that the modules with the same color cells to
be installed together.
To ensure ventilation and heat dissipation ,The minimum clearance between module frame and wall
or roof should be ensure 115 mm at least.
The module frame has the effect of thermal expansion and cold contraction ,the minimum clearance
between two adjacent modules must not be less than 20mm.
The module frame drain holes cannot be blocked in any situation during installation or use.
Packaging angle bead and assembly safe edge play a protective role in packaging and
transportation, which can be removed automatically when assembly is installed
All the load values below are the test load of laboratory static mechanical load experiment, and the
actual design load of the project site needs to consider 1.5 times of safety factor.
The PV support system is generally divided into fixed installation system and tracker system. Risen PV
module can be installed on two systems. The PV module and support system can be connected by bolts
and clamp. Risen recommends some installation methods and accessories, as follows, please give priority.
Other installation methods need to be confirmed with Risen.

8.1.2 Fixture installation：
The Risen PV module can also be installed with clamp. The PV module shall be fixed on the mounting
bracket with M8 bolts and clamp. It is strictly forbidden for the clamp to contact the front glass. The
aluminum frame of the PV module shall not be deformed during installation, and the front of the module
shall not be covered. Each PV module needs to be fixed with at least four clamp, and the applied torque
is 16N · m ~ 20N ·m.
The size, quantity and installation method of the clamp can be determined according to the actual load
of the project site, but it needs to meet the basic requirements in table 8-4 and be confirmed by the
professional technical team of Risen.
