The fault probability of the modules in the later
operation is extremely low.
You can use the below fault judgment methods:
apperance defects, such as break, cracked, su
rface stripping and so on, the electrical perform
ance of the whole string or of the whole module
failed.
For the fault modules, you cannot disassemble
them by yourself. Disassembling must be exec
uted by qualified experts. You should contact o
ur sales persons at once to apply for repaire or
replacement of the fault modules. (the modules
need to be replaced must be the same kind a
nd type ,if needed) .
Modules can operate effectively without ever
being washed, although removal of dirt from the
front glass can increase output. The glass can
be washed with a wet sponge or cloth. Wear
rubber gloves for electrical insulation.
8 SAFETY PRECAUTIONS
Module installation and operation should be
performed by qualified personnel only. Children
should not be allowed near the solar electric
installation. Modules of unpacking, transport,
installation process must be handled with care.
To avoid collision with the sharp and hard
objects so as not to cause damage and affect
the normal use.
Module must be installed in the absence of
shadowed areas, otherwise it will not work to
generate electricity. If the module long
shadowing state (dust and bird feces shadowed)
to work, it will Breakdown caused by
overheating
Avoid electrical hazards when installing, wiring,
operating and maintaining the module. Modules
produce DC electricity when exposed to light
and therefore can produce an electrical shock
or burn. Modules produce voltage even when
not connected to an electrical circuit or load.
Modules produce nearly full voltage when
exposed to as little as 5% of full sunlight and
both current and power increase with light
intensity. Do not touch live parts of cables and
connectors. As an additional precaution, use
insulated tools and rubber gloves when working
with modules in sunlight.
Fall of modules from high place will cause
death, injury or damage. Do not drop module or
allow objects to fall on module. Never leave a
module unsupported or unsecured. If a module
should fall, the glass can break. A module with
broken glass cannot be repaired and must not
be used.
When installing or working with module or
wiring, cover module face completely with
opaque material to halt production of electricity.
Modules have no on/off switch. Modules when
exposed to sunlight generate high voltage and
are dangerous. Modules can be rendered
inoperative only by removing them from
sunlight, or by fully covering the front surface
with opaque cloth, cardboard, or other
completely opaque material, or by working with
modules face down on a smooth, flat surface
when installing or maintaining.
Do not expose the artificially concentrated
sunlight to a module.
Trunsun modules are designed to fulfill the
criteria of Application class A requirements
according to IEC61730-1.Modules rated for use
in application class A may be used in systems
operating at greater than 50V DC or 240W,
where general contact access is anticipated.
Modules qualified for safety through
IEC61730-1 and IEC61730-2 within application
class A are considered to meet the
requirements for safety class
Ⅱ
referring to
IEC61140.
Modules can produce higher output than the
rated specifications. Industry standard ratings
are made at conditions of 1000 W/m2 and 25°C
cell temperature. Reflection from snow or water
can increase sunlight and therefore boost
current and power. In addition, colder
temperatures can substantially increase voltage
and power. Modules are intended for use in
