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.

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 anti-inverted sticks and
other 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.

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,
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.
Solahart 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 on the
PV module outer packaging (for example, 270W-L
means low current bin; 270W-H means high current bin;
the current division method required by other customers
is similar); According to the system design
requirements, modules of the same current bin are
usually required to be installed in the same array.
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 up. According to the system
design requirements, the color of PV modules in the
same row or the same array should be the same.
