1.3 Precautions of Installation
1.3.1 Module’s unpack and transfer
a) When the whole pallet of modules are delivered to the site and unloaded, make sure the
safety of the modules especially if they need to be lifted for roof projects. Put them into a
protective device and then lift it to the roof in case of bumping against the wall during the
lifting process.
b) Firstly, tear the stretch film, then move away the top cover after cutting off each module
packing strip while unpacking. Two operators work as a group, grasp the module frame
tightly in the same direction and take out the module one by one. It is a must that the
operators remove the adhesive tape of the fixed module one by one, rive one piece and
then take out one piece of module. We don’t allow to tear off all the adhesive tape at one
time to prevent the whole package from toppling over or falling down. The whole process
must be taken very gently. Don’t collide with any hard objects or let any parts of the frame
touch and drag on the ground.
c) After unpacking the modules should be installed that day as far as possible. It’s
Chint Solar (Zhejiang) Co.,Ltd. | Add:1335 Bin´an Road, Binjiang District, Hangzhou | P.C: 310053
Tel: 0086-571-5603 1888 | Fax: 086-571-5603 2316 | Website: http://energy.chint.com/
recommended to take the right amount of modules according to the progress of the project
every day. Heavy rain and other inclement weather may have the potential to soak the
packaging which can affect product reliability, such as storms, typhoons, hurricanes or other
events in which they may be blown away. If the users need to store modules before
installation, do not open the package, the goods should be stored in a room temperature,
dark, dry and ventilated place.
1.3.2 Module’s Stack
a) When a module is taken out of the box, cardboard bedding below should be applied in order
to avoid contact with cement surface / ground, hard metal or tile. Modules should be placed
neatly and should not be dropped, slammed or scratched.
b) When stacking modules, it needs to be stacked neatly in the horizontal plane, under the
condition of the glass facing down and the back way piled up, while the cardboard bedding
need to be underside the modules. If the modules will be installed on the rooftop, the
number of each stack is suggested no more than 20. In case of the poor load-bearing
capacity, it’s recommended that the designer and/or installer check with the structural
engineer or architect to determine the amount of load allowable for specific location. During
the whole process, the installation tools and other objects must be prevented from
contacting the module surface.
c) If the modules are requested to be classified by current, the handling personnel are required
to carry out of the level of the current and make a mark separately according to the power
on the list. (e.g. 275W-L, identifies the modules of the packaging according to the power on
the list, indicating a low current position; 275W-H, compared to high current position).
Usually, the same series of modules in the same current position are required in
accordance with the system design requirements.
d) If the modules are color-coded and marked the corresponding logo on the carton due to the
customer requirements, when modules are taken out and stacked, they should be labeled to
avoid confusion. Usually the same row or the same square have the same color according
to the system design requirements.
e) Due to the complexity and difference of the construction site, these precautions may not
cover all items, please refer to the specific construction standards.
