Installation Manual for DualSun PV Modules
Make sure that back plate of modules will not contact bracket into the module or building
structures, especially when the module surface is imposed by pressure.
DualSun Modules have been certified for a maximum design static load on the back of the
Modules of up to33.4 lb/ft
2
(i.e. wind load) and a maximum design static load on the front of the
Modules of up to33.4 lb/ft (i.e. wind and snow load), depending on the clamp mounting (please
refer to follow installing data for this information). And this is printed on the label of modules.
Maximum static load of the PV module by: front 5400pa and back 2400pa, it depends on the
components of the installation type (please refer to the following installation), as described in this
manual load for the test load. Note: on the basis of IEC61215 - 2016 installation requirements, when
computing the corresponding maximum design load, need to consider the safety factor of 1.5 times.
Module installation methods cannot lead to electrochemical corrosion between module aluminum
frame and different metals.
Modules can be installed horizontally or vertically.
