MOUNTING OVERVIEW
5.1 MOUNTING
Solar PV modules usually can usually be mounted by using
the following methods: bolts or clamps.
PV modules can be mounted to a substructure with either
corrosion-proof M8 (bolts placed through the mounting
holes on the module frame) or with specially designed
module clamps.
Note: All installation methods herein are only for
reference. Boviet Solar will not provide related BOS
components. The system installer or trained professional
personnel must be responsible for the PV system's design,
installation, mechanical load calculation and security
of the system.
Figure 2: PV Module I Mechanical Drawing
Regardless of the method, the final installation of the
modules should ensure that:
A clearance of at least 115mm (4.5in) is required provided
between the module frame and the surface of the wall
or roof. The minimum distance between two modules is
10mm(0.4in).
The mounting method should not block the drainage holes.
Panels are not subjected to wind or snow loads exceeding
the maximum permissible loads and are not subject
to excessive forces due to the thermal expansion
of the support structures.
Note: The drainage holes cannot be blocked in any
situation during installation or use.
For bifacial modules (double-sided glass),
they must be installed with all 12 holes (blue,
and red) when the snow pressure and wind
pressure reach the maximum.
