Installation Manual

 - Jolywood N-type Mono-crystalline Double Glass Module

6.3     Cleaning

The  amount  of  electricity  produced  by  a  solar 
module  is  proportional  to  the  amount  of  light 
reach  on  surface  of  it.  A  dust  covered  module 
produces relatively lower power, so it is important 
to keep module clean.

6.3.1     Water quality requirements

6.3.2     Module inspection after 

             cleaning

6.3.2.1

PH: 5 ~7;
Chloride or salt content:0 - 3,000 mg/L;
Turbidity:0-30 NTU;
Conductivity:1500~3000 μs/cm;
Total dissolved solids:≤1000 mg/L;
Water hardness:0-40 mg/L;
Non-alkaline  water  must  be  used,  use 
demineralized  water  when  conditions  are 
available.

Note: when using robot clear modules, Jolywood 
recommends  using  soft  plastic  brush.  Module 
damage,  poor  appearance  and  power 
degradation caused by improper robot clear are 
not within the warranty scope of Jolywood;

a) 

The PV module should be cleaned under 

the  irradiance  of  less  than  200W/m2.  Avoiding 
cleaning  water  with  great  different  temperature 
from air to avoid cracking. Hard water needs to be 
softened. The water remains should be removed 
from glass surface after cleaning.

b) 

It is strictly forbidden to clean PV modules 

under  special  weather:    wind  level  greater  four, 
heavy rain or heavy snow.

c) 

During  cleaning,  the  water  pressure  on 

the surface of module glass shall not exceed 4MPa 
,  and  the  module  is  not  allowed  to  withstand 
additional external force.

d) 

During cleaning, it is strictly forbidden to 

step on the modules, splashing water to the back 
of the modules or cables. Ensure that connectors 
are  clean  and  dry  to  prevent  electric  shock  and 
fire  hazard.  Steam  clean  machines  are  strictly 
prohibited;  soft  parts,  Cloth  and  mild  detergent 
and  water  should  be  used.  Do  not  put  modules 
directly  into  the  water.  Serious  thermal  shocks 
also could damage modules.

e) 

The difficult-to-clean substances such as 

oil on the surface of modules, use a non-friction 
neutral  liquid  cleaner.  Do  not  use  any  organic 
solvent  containing  alkali  or  acid.  Do  not  use 
corrosive solvents or wipe the PV modules with a 
hard object.

f) 

If you are not sure whether the array need 

to  cleaned,  first  select  a  column  of  particularly 
dirty  array  to  begin  cleaning.  If  the  power 
generated  increased  less  than  5%,  cleaning  is 
usually  not  required.  The  above  verification 
should  be  carried  out  only  under  a  stable 
sunshine rate (sunny, strong sunshine, no cloud).

g) 

The back of the PV module usually does 

not need to be cleaned;  If you need to clean the 
back of the PV module , ensure that the cleaning 
liquid does not penetrate into the bottom layer of 
the material. 

h) 

Regularly  trim  the  vegetation  to  prevent 

shading  created  on  the  module  surface,  which 
would decrease power generation.
