In the northern hemisphere, modules should typically face
south, and in the southern hemisphere, modules should
typically face north; For detailed information on the best
installation angle, please refer to standard solar photovoltaic
installation guides or consult a reputable solar installer or
systems integrator.
5.2 Mechanical installation
Ensure that the installation method and supporting system of
modules is strong enough to make the modules to be able to
withstand all the pre-established load conditions. The installer
must provide the guarantee. The installation supporting
system must be tested by the third-party organization with the
analysis ability of Static Mechanical, according to the local
national or international standards such as DIN1055 or
equivalent standards.
The modules mounting structure must be made of durable,
corrosion-resistant and UV-resistant material; Modules must
be securely attached to the mounting structure; In regions with
heavy snowfall in winter, select higher mounting system. So
that the lowest edge of the modules will not be covered by
snow for long time. In addition, ensure that the lowest portion
of the modules is placed high enough so that it will not be
shaded by plants or trees, or damaged by flying sand; Because
of thermal and expansion of the module frames, must ensure
that the minimum distance between neighboring frames is
10mm.
5.2.1 Installation onto the curtain wall surface
Cleaning the surface carefully and spreading the structural
adhesive on it along the longitudinal direction of the modules.
Adhesive column should roughly follow the area of 1650mm
long, 6~10mm wide, 3~5mm thick, and have the gap of
240mm between each other. Sticking the Lohmann
double-sided tape of 1600mm long and 17mm wide onto each
long edge of the modules to prevent falling off before the
structural adhesive solidified. In order to achieve the best
bonding performance, it is required to install the modules
within 5 minutes once the adhesive is applied on the wall.
Then pressing the modules gently against the surface (screws
could also be applied as auxiliary method as per customer’s
requirements). The gap between each module shall be kept
around 1cm.
5.2.2 Installation on the steel tile
Spreading the structural adhesive onto the raised part of tile
Structural adhesive(8~10mm width)
