UV-resistant material. Modules must be securely attached to the mounting structure.
4.1.5 In regions with heavy snowfall in winter, select the height of the mounting system, so
that the lowest edge of the modules is not covered by snow for any length of time. In
addition, ensure that the lowest portion of the modules is placed high enough so that it is
not shaded by tress or other plants.
4.1.6 When the modules are supported parallel to the surface of a building roof, a minimum
clearance of 10cm between the module frame and the surface of the roof is required to
allow air to circulate behind the modules and to prevent wiring damage.
4.1.7 Chint solar modules are designed to meet the requirements of IEC61730 and UL 61730,
application the fire performance Class C (IEC61730) and type 4 (UL61730).
4.1.8 Observe the linear thermal expansion of the modules frames, must ensure that the
minimum distance between neighboring frames is 10mm.
4.2 Tilt Angle Selection
The tilt angle of the modules is measured between the surface of modules and a horizontal
grounding face, as shown in figure a. 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
