If the above precautions are not followed, the
Chint Solar Warranty will be invalid.

Installation angle selection
The tilt angle of the modules is measured between
the surface of modules and a horizontal
grounding face, as shown in figure 1. The
modules generate maximum power output when it
faces the sun directly.
In the northern hemisphere, modules should
typically face south, and in the southern
hemisphere, modules should typically face north.
Dust building up on the surface of the modules
can impair module performance, Chint Solar
recommends installing the modules with a tilt
angle of at least 10 degrees, making it easier for
dust to be washed off by rain. At the same time, it
is conducive to the flow of accumulated water on
the surface of the module, and avoids long-term
large amounts of accumulated water leaving
marks on the glass surface, thereby affecting the
appearance and performance of the module.

PV modules connected in series should be
installed in the same orientation and angle. If the
orientation and angle are different, the solar
radiation received by each module may be
different, resulting in power loss.

Installation Method
The photovoltaic module mounting bracket must
be made of durable, corrosion-resistant, and
UV-resistant materials. The mounting bracket
must be inspected and tested by a third-party
testing organization with static mechanical
analysis capabilities to meet the country, region,
or corresponding international standards.
The photovoltaic module must be firmly fixed on
the mounting bracket. If the photovoltaic module
is installed in a snow-covered area, the height of
the support should ensure that the lowest point of
the photovoltaic module will not be covered by
snow. In addition, it should be ensured that the
lowest point of the photovoltaic module will not
be blocked by surrounding trees or other plants.
When the photovoltaic module is installed on a
bracket parallel to the roof, the minimum gap
between the frame of the photovoltaic module
and the roof is 10cm, and air circulation is
required to prevent damage to the wiring of the
photovoltaic module.
The frame of the photovoltaic module will have
