it is recommended that the designer or installer
evaluate the load-bearing capacity of the roof and
reduce the load-bearing unit area of the roof by
reducing the number of piles. At the same time, avoid
installation tools and other objects on the surface of
the photovoltaic module.
Chint PV modules adopt high and low current
bins, and the handlers need to place them separately
and mark them according to the markings on the
power list of the PV module outer packaging (for
example, 270W-L means low current gear; 270W-H
means high current Gear position; the current division
method required by other customers is similar);
According to the system design requirements, the same
current gear position is usually required in the same
array during installation.
If the customer requires PV modules to be
distinguished by color, the outer packaging box shall
be marked accordingly, and the PV modules shall be
marked to prevent confusion when they are taken out
of the packaging box and stacked. According to the
system design requirements, the color of photovoltaic
modules in the same row or square array should be the
same.

Installation conditions
Recommended ambient temperature: -20°C to
+50°C;
extreme
working
environment
temperature of photovoltaic modules: -40°C to
+85°C.
Photovoltaic module mechanical load: Under
standard installation conditions, the maximum
test snow/wind load is 5400Pa/2400Pa, and the
design load (considering a safety factor of 1.5) is
3600Pa/1600Pa. For specific installation methods
and mechanical load values of photovoltaic
modules, please refer to Table 2 for detailed
installation instructions for photovoltaic modules.
Photovoltaic modules are strictly prohibited to be
installed and used in excessive environments such
as hail, snow, hurricane, sandstorm, dust, air
pollution, and soot. It is strictly forbidden to
install or use photovoltaic modules in a closed
environment with strong corrosive substances
(such as salt, salt spray, salt water, active
chemical vapor, acid rain, strong steam, or any
other substances that will corrode photovoltaic
modules and affect the safety or performance of
photovoltaic modules. ) In the environment.
If photovoltaic modules will be installed in
special environments such as high temperature
and high humidity environment, wet salt fog
environment (C3 and above areas specified in
ISO 9223), water and breeding farms, etc., the
purchaser or user must inform Chint in advance.
