7.2
PV module cleaning
If the PV module has a sufficient angle of tilt (at least
15°), it is generally not necessary to clean the PV
module (as the rainfall will provide a self-cleaning
effect). If there is a large accumulation of dirt on the
PV module surface that has seriously affected the
power production, the module can be rinsed with water
without detergent, and use a gentle sponge or brush to
clean the surface during the cooler hours of the day.
Dust must not be scraped or wiped off under dry
conditions as this may result in tiny scuff marks. For
snow removal, the PV module surface can be cleaned
with a brush with soft bristles.
For more details on cleaning and maintenance, please
refer to the PV Module Cleaning Manual.
