7.0 MAINTENANCE 

 

Do not

 make modifications to any component of the PV 

module (diode, junction box, connectors or others). 

 

Regular maintenance is required to keep modules clear 
of snow, bird droppings, seeds, pollen, leaves, branches, 
dirt spots, and dust. 

 

Modules with sufficient tilt (at least 15°), generally may 
not  require  cleaning  (rain  will  have  a  self-cleaning 
effect).  If  the  module  has  become  soiled,  wash  with 
water and a non-abrasive cleaning implement (sponge) 
during the cool part of the day. Do not scrape or rub dry 
dirt away, as this may cause micro scratches. 

 

Snow should be removed using a soft brush. 

 

Periodically inspect the system to check the integrity of 
all wiring and supports. 

 

To protect against electric shock or injury, electrical or 
mechanical  inspections  and  maintenance  should  be 
performed by qualified personnel only. 

8.0 Module Cleaning Guidelines 

This  manual  covers  the  requirements  for  the  cleaning 
procedure  of  Canadian  Solar  double  glass  photovoltaic 
modules. The purpose of these cleaning guidelines is to 
provide general information for cleaning Canadian Solar 
modules. System users and professional installers should 
read  these  guidelines  carefully  and  strictly  follow  these 
instructions. 

Failure to follow these instructions may result  in death, 
injury or damage to the photovoltaic modules. Damages 
induced  by  inappropriate  cleaning  procedures  will  void 
Canadian Solar warranty. 

 

SAFETY WARNING 

 

Cleaning  activities  create  a  risk  of  damaging  the 
modules and array components, as well as increasing 
the potential electric shock hazard. 

 

Cracked or broken modules represent an electric shock 
hazard due to leakage currents, and the risk of shock is 
increased  when  modules  are  wet.  Before  cleaning, 

thoroughly  inspect  modules  for  cracks,  damage,  and 
loose connections. 

 

The  voltage  and  current  present  in  an  array  during 
daylight hours are sufficient to cause a lethal electrical 
shock. 

 

Ensure that the circuit is disconnected before starting 
the  cleaning  procedure  as  contact  with  leakage  of 
electrically active parts can result in injury. 

 

Ensure that the array has been disconnected to other 
active components (such as inverter or combiner boxes) 
before starting with the cleaning. 

 

Wear suitable protection (clothes, insulated gloves, etc.). 

 

Do  not

  immerse  the  module,  partially  or  totally,  in 

water or any other cleaning solution. 

 

Rear  side  cleaning  of  the  modules  is  not  required,  if 
cleaning the rear of a module is desired, care should be 
taken  to  ensure  there  is  no  damage  caused  to  the 
module by simply clearing the contaminant by hand or 
with a soft sponge. 

HANDLING NOTICE

 

 

Use a proper cleaning solution and suitable cleaning 
equipment. 

 

Do not

 use abrasive or electric cleaners on the 

module. 

 

Particular  attention  should  be  taken  to  avoid  the 
module  rear  glass  or  frame  to  come  in  contact  with 
sharp objects, as scratches may directly affect product 
safety. 

 

Do  not 

use  abrasive  cleaners,  de-greasers  or  any 

unauthorized  chemical  substance  (e.g.  oil,  lubricant, 
pesticide, etc.) on the module.   

 

Do  not 

use  cleaning  corrosive  solutions  containing 

hydrofluoric acid, alkali, acetone, or industrial alcohol. 
Only substances explicitly approved by Canadian Solar 
are allowed to be used for cleaning modules. 

 

For  cleaning  methods  using  rotating  brush,  please 
consult with Canadian Solar's technical support before 
using.
