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.
7. Installation
7.1. Environment conditions and site selection
Risen module should be installed in the following environmental conditions.
Table 7-1 operation condition
NO Environmental conditions Range
1 Recommended Working temperature -20°C to+50°C.
2 Extreme Working temperature -40°C to +85°C
3 Storage temperature -20°C to +50°C
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

15
RS/03-GT-016-2019 日期：2020-3-9
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.
According to IEC 61701, salt mist corrosion testing of photovoltaic (PV) modules, Risen Solar
modules can be installed in corrosive salt areas within proximity of the ocean or sulfurous areas. The
module must not be soaked in the water or be installed in the environment (i.e., fountain, spindrift,
etc.) where the module would touch water (pure water or brine) for a long term. If the modules are
placed in an environment of salt fog (i.e., marine environment) or sulfur (i.e., sulfur sources,
volcanoes, etc.), there is a risk of corrosion.
According to the test result of IEC62716:2013 “Ammonia corrosion testing of photovoltaic (PV)
modules” for ammonia resistance, Risen Solar modules can be safely installed in ammonia-heavy
environments, such as farm, meadow and so on. I
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.

16
RS/03-GT-016-2019 日期：2020-3-9
Installation inclination refers to the Angle between the solar photovoltaic module and the ground
plane, as shown in Figure 7-1.
Fig. 7-1 Tilt angle
Table 7-2 Recommended tilt angle for fixed systems
latitude Fixed angle of inclination
0°~15° 15°
15°~25° The same latitude
25°~30° Same latitude +5°
30°~35° Same latitude +10°
35°~40° Same latitude +15°
40°+ Same latitude +20°
7.3. Installation requirements for bi-facial dual glass 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.
Fig. 7-2 Distance from the earth
In the system design, besides the ground type and the module installation height to ground, the proper
array spacing and how to avoid shadow shading on the back need to be considered too, please consult with
the professional system designer.
8. Installation Guidelines
