MAINTENANCE 

 

In order to maintain the optimum 

output of the module, quality and 

safety, please conduct periodic in-

spection or cleaning. 

 

It is also recommended to inspect 

the electrical and mechanical con-

nections annually. 

 

If you need electrical or mechanical 

inspection or maintenance, it is rec-

ommended to have a licensed au-

thorized professional carry out the 

inspection or maintenance to avoid 

the hazards of electric shock or inju-

ry. 

ANTI-REFLECTION GLASS SUR-

FACE CLEANING 

 

Light dirt that does not shield light 

completely does not significantly 

degrade power generation perfor-

mance, but if the module surface 

becomes dirty, it may reduce output 

power,  malfunction or hotspot may 

occur. 

 

It is recommended to clean the sur-

face of the module with water and 

a soft cloth or sponge. 

 

When cleaning with neutral glass 

detergent or weak alkaline glass 

detergent, it is recommended to 

start with smallest area and from 

the edge of solar modules in order 

to check no damage occurs to the 

glass. 

 

After that, clean surface of glass 

with wet and clean cloth. 

 

Recommended detergent: "Glass 

Magiclean"

1) 

or "Windex®  Original"

2)

 

1) 

Glass Magiclean is a trademark 

of Kao Corporation. 

2) 

Windex®  is a trademark of SC 

Johnson & Son, Inc. 

 

It is recommended to read carefully 

the manuals of detergent and un-

derstand notes on usage and first-

aid treatment. 

 

To remove persistent dirt, the mod-

ule can be washed with a micro-

fiber cloth and ethanol. 

 

Never use abrasive detergent, 

strong alkaline detergent, strong 

acid detergent or a detergent which 

forms a protective layer on the sur-

face of the glass to clean any part of 

the module. The performance of a 

solar modules may be reduced. 

Please be very careful since the war-

ranty will not cover the damages 

caused by detergents. 

 

When cleaning the PV module, 

please do not put detergent on 

junction box or connector. If deter-

gents and chemical substances ad-
