10. MAINTENANCE
Cleaning method of ARC-Glass of Silfab PV Module
Silfab uses anti-reective coated glasses for maximum
performance. It is recommended to regularly clean the
modules to ensure maximum power output.
Module cleaning should be done in the early morning, in the
evening, at night or on rainy days when solar irradiance is low.
Detailed description:
• Do not touch the glass with bare ngers or hands.
Wear clean gloves to prevent ngerprints and oth-
er dirt from staying on the glass.
• Do not use metal tools, such as blades, knives, steel
wood and other abrasive materials. Cleaning the
glass with hard surface will scratch the ARC-glass.
• Do not use high pressure washers, abrasive
brushes, powders, cleaners, polishers, sodium hy-
droxide, benzene, nitro-thinners, acid or alkali and
other chemical substances. Doing so may damage
the anti-reective coating that is present on the
glass of the modules and void warranty.
• All types of commercial glass cleaners, or alcohol/
ethanol/methanol can be used.
ROUTINE STEPS OF CLEANING:
1
Whisking: Debris such as dust and leaves on
module surface should be removed with
dry cloth.
2
Scraping: hard foreign matters such as dirt,
bird droppings, plant branches, etc., should
be scraped off with non-woven fabric or
hair brush.
3
Washing: Colored substances, such as bird
dropping, plant juices, etc., on module surface
can be removed by cleaning by spraying wa-
ter onto the dirty region and scraping with hair
brush or non-woven fabric. The pressure of
the cleaning water should be less than 690Kpa
(100 PSI).
4
Cleaning of snow: Silfab modules can withstand
heavy snow pressure up to 5400 Pascal. Do not
try to remove frozen snow or ice from the mod-
ule. Use a hair brush to gently remove the snow.
