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.
