CLEANING METHODS
Method A: Compressed water
Requirement for water quality:
PH: 5 ~7;
Chloride and Salinity
:
0 - 3,000 mg/L
Turbidity
:
0-30 NTU
Conductivity
:
1500~3000 μs/cm
Total dissolved solids (TDS)
:
≤1000 mg/L
Water hardness (calcium and magnesium ions)
:
0-40 mg/L
Non-alkaline water must be used; demineralized water shall be used when conditions are
available
The maximum water pressure recommended is 4 MPa (40 bar)
Method B: Compressed Air
Trina Solar recommends using this method to clean the soft dirt (like dust) on modules. This
technique can be applied as long as the method is efficient enough to clean the modules considering
the on-site conditions.
Method C: Wet cleaning
If excessive soiling is present on the module surface, a non-conductive brush, sponge, or other mild
agitating method may be used with caution.
Please make sure that any brushes or agitating tools are constructed with non-conductive materials
to minimize risk of electric shock and that they are not abrasive to the glass or the aluminum frame.
If grease is present, an environmentally friendly cleaning agent may be used with caution.
Method D: Cleaning robot
If a cleaning robot is used for dry cleaning, the brush material is required to be soft plastic material,
and the glass surface and aluminum alloy frame of the module will not be scratched during the
cleaning process and after cleaning. The weight of the cleaning robot should not to be too large. If
the cleaning robot is improperly used, and the resulting module damage and power attenuation are
not covered by
Trina Solar’s warranty.
TROUBLE SHOOTING
If your PV system does not work normally after installation, please inform your installer immediately.
It is recommended to perform preventive inspections every six months, and do not change the
components of the modules without authorization. If electrical or mechanical performance inspection
or maintenance is required, they should be operated by qualified professionals to avoid any electric
shock or personal injury.
