Acceptable Dry Cleaning
Prohibited Dry Cleaning
►
Dry cleaning with soft cloths or mops is allowed up to 26 times
annually.
►
Excessively soiled spots on modules (i.e. bird droppings) may
be spot-cleaned with soft cloth or mop and water if necessary
for localized cleaning only (<10% of module area).
►
Backside cleaning: potential for
accidental stress to lead wire or junction
box.
►
Dry cleaning with anything other than
soft cloths or mops (i.e. bristle brushes,
sponges, or squeegees).
Cleaning systems or processes that do not comply with the Module Cleaning Guidance must be reviewed
and approved prior to use. Additional information may be requested from the First Solar Technical Support
team at

Important
First Solar does not warrant against damage to modules that are deemed to be
caused by the cleaning methods used. Failure to comply with the Module
Cleaning Guidelines may void warranty.
Cleaning solutions vary in design and size and can affect the load dispersed onto the modules. Load
specifications and data must be identified and submitted with documentation for cleaning system approval.
First Solar recommends no more than 40.8 kg (90 lb) per module that is evenly distributed while cleaning.
►
Specific contact points (wheels or belts) can affect the load and pressure placed on the modules.
Review of this critical information is part of the approval process.
►
Below are some examples of loads that shall not be exceeded:
o
Point loads (P1)
-
Max of 13.6 kg (30 lb) each spaced 40.6 cm (16 inches) apart
o
Up to 0.18 kg/cm1 (P2) (lb/inch) of contact length for a drive belt anywhere on the module
o
Up to 0.18 kg/cm (P3) (1 lb/inch) of contact length for brushes contacting the module
anywhere on the module
o
Some combination of the above load types so that P1 + P2 + P3
≤
40.8 kgf (90 lbf)
►
Cleaning solutions must not affect or jeopardize any part of the mounting system.
o
This includes all parts of the mounting system: clips, rails, and trackers
►
Vibration from the cleaning solution shall not cause module breakage or any movement of the
modules in their mounting hardware.
