5. Introduction to installation method
5.1 Introduction to installation environment
DAS Solar recommends that the Modules shall be installed in an environment with the operating ambient tem-
perature of -20 ° C- 50 ° C (-40 ° C - 85 ° C under extreme conditions). Please provide protective measures in
sandstorm, prevent sands from entering the Modules, otherwise the installation and performance may be affected.
Generally, the Module shall be installed in a location which receives the most solar radiation in a whole year. In
the northern hemisphere, the Module shall be installed to the south, and to the north if in the southern hemisphere.
If Module's tilting angle deviates from due south (or due north) by 30 degrees, the power output will be 10% to 15%
less, and 20% to 30% less if 60 degrees. When choosing the ideal location, please avoid trees, buildings and other
obstacles which may shade the Module. Although we have installed appropriate bypass diodes to minimize the
loss, shade will always reduce the output power.
When the photovoltaic generation system is used with battery, please install the battery in strict accordance
with relevant laws and regulations. In doing so, the operation of the system can be protected, and the user's safe
use can be assured. Please observe the recommendations of the battery manufacturer in relation to installation,
operation and maintenance of the battery. Generally speaking, the battery shall be kept away from main traffic
routes of people and animals.
While ensuring normal operation of the battery, please avoid sunlight exposure and rain & snow erosion, and
keep good ventilation; Most batteries generate hydrogen while in charging, which can be explosive easily, thus
please do not create any open fire or spark in the surrounding environment of the battery; If the battery is installed
outdoors, please make sure to place it in a specially designed location and keep good insulation and ventilation.
When the Modules are to be stacked on the roof, please first verify the bearing capacity of the roof, and pre-
pare a construction plan conforming to applicable specification requirements.
When the Module is used in an area with high wind pressure and high snow pressure, please provide a struc-
tural design of supporting and fixture according to the local design specification, and ensure that the external load
doesn't exceed the mechanical strength of the Module.
According to the salt-spray corrosion test of the photovoltaic Module conducted according to the requirements
of IEC61701, the photovoltaic Module of DAS Solar can be installed in coastal or corrosive environment, however it
can't be immersed in water or kept moist (e.g. by foundation, wave) If the Module is installed in a salt-spray (e.g.
maritime environment) or sulfur-containing (e.g. Volcano) environment, it may be exposed to the risk of corrosion.
The installation location of the module should be > 50 meters from the coastline. For photovoltaic projects with
a distance of less than 50 meters from the coastline, please contact the DAS solar sales staff to confirm the product

5.2 Module tilting angle
The tilting angle of photovoltaic Modules refers to the included angle between the photovoltaic Module and the
level ground. Different tilting angles can be adopted for different projects due to varied local conditions. DAS Solar
recommends that the tilting angle of the Module shall not be less than 10 ° . For your ideal choice of tilting angle,
please refer to the design procedures, specifications, regulations or follow the recommendations of the Module
installation provider.
In terms of ideal installation, the Module shall face south for installation in the northern hemisphere, and face
north in the southern hemisphere. If the photovoltaic Module is installed in North America or other regions where
UL standard applies, then, according to local laws and regulations, a clearance of 155mm (recommended value)
shall be reserved between the Module (backboard surface) and the wall or roof surface. If other installation specifi-
cation is adopted, the UL certification or fire resistance grade of the photovoltaic Module may be affected.
The Module can be installed by the following methods: Bolt installation and fixture installation. The installation
of the Module shall be in strict accordance with the operation instructions provided in this manual so as to conform
to IEC certification. Prior to Module installation, please go through these instructions to get familiar with the entire
installation procedures.
The connection between the Module and the bracket system can be made through the mounting holes of the
frame, fixture, or snap-in system. Module installation must be in line with the installation requirements. If the
Module is to be installed in a way inconsistent with the instructions declared by DAS Solar, please consult the local
technical support or after-sales personnel of DAS Solar and obtain the consent of DAS Solar, otherwise, the
Module may be damaged and the product warranty will be invalidated.
The term "load' mentioned in this manual refers to test load. For the installation method conforming to local
laws and regulations, the safety coefficient of 1.5 shall be adopted when estimating the allowable maximum design
load. The project design load is dependent on structure, application standard, installation location, and local climate
condition. The design load shall be determined by professional supplier or professional engineer. For details,
please comply with local architectural regulations or contact professional architectural engineer.
The described Module shall be installed on an extended continuous bracket underneath the Module. If the
Module is to be installed without a continuous bracket, the maximum allowable load of the Module will decrease,
which shall be reviewed by DAS Solar.
The maximum spacing between two Modules is 5mm. If special brackets are used, you may determine an ap-
propriate interval according to the technical requirements of the bracket supplier.
Note: All installation methods introduced herein are for reference only. DAS Solar is not responsible for provid-
ing relevant installation parts, and the design and installation of the Module system. The mechanical load and
safety must be verified by a professional system installation provider or qualified persons with corresponding expe-
rience.
Prior to installation, please make the following major verifications:
•Please check whether the appearance is defective, whether there are any sundries, and verify the safety per-
formance of the wiring box. If any sundries, please remove them.
