the module.
We recommend the following to be used:
Water with low mineral content
Near neutral pH water
The maximum water pressure recommended is 4 MPa (40 bar)
Cleaning Methods
Method A: Compressed Air
Canadian Solar Inc. recommends cleaning the soft dirt (like dust) on modules just with air pressure. This
technique can be applied as long as the method is efficient enough considering the existing conditions.
Method B: 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.
Ensure 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 environmental friendly cleaning agent may be used with caution.
