when the PV modules are removed from the container,
the distance between the upper surface of the forklift
tines and the ground should be less than 80mm,
otherwise collisions may easily occur, which may
damage PV modules.
4.2 Unpack
When unpacking, you need to tear the stretch film first,
then use a knife to cut the binding tape, and remove
the packing box cover.
If the inner packaging is fixed with anti-falling tape, two
people in a group should hold the frame with both hands
in the same direction to take out one piece of PV module
each time. Take out the PV module by tearing a piece
of fixing glue, and do not remove the fixing tape at one
time to prevent the whole PV module from tipping.
Unpacking should follow the steps of tearing off one
piece of the fixing tape followed by taking out one piece
of PV module, instead of tearing off all fixing tape
which may cause module collapsing. If the internal
packaging is fixed by the internal packing belt, first cut
the internal packing belt, use non-sharp and stable items
to prop up one of the long-side enclosure frame, and
then cut the other side of the frame. Two people in turn
move and take out the PV modules. The whole handling
process needs to be handled gently to avoid any
collision with hard objects and any part of the frame
dragging on the ground.
4.3 Stack
When taking out the PV module from the packing box,
put the cardboard on the ground first to prevent the PV
module from colliding and scratching with the cement
surface, hard object on the ground, color steel tile,
7
metal corrugated, etc.
When the PV modules are stacked, they must be neatly
and stably stacked on a horizontal surface, and stacked
with the glass side facing down and the back side facing
up. At the same time, there must be cardboard bedding
under the PV modules. For example, when installing PV
modules on the roof, the number of piles should not
exceed 20. For roofs with poor load-bearing capacity, 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 PV module.
