      Please carefully check the modules of the existence of visual defects, focusing on the following items: 

a)

 

Check whether the module glass is broken. 

b)

 

Check if the front of the module is obstructed by obstacles or foreign objects. 

c)

 

Check the module negative-sheet whether there is hot, negative film raised, burn through the traces 

and so on. 

d)

 

Check  whether  the  cell  bus–bar  is  corroded,  whether  encapsulation  materials  of  the  module  has 

delamination, bubbles, etc. 

e)

 

Check the tightness of the bolts and the electrical connections at the connection points between the 

modules and the supporting rail. 

8.3 Inspection of connector and cable 

      It is advisable to carry out a preventive check every 6 months and check the following: 

a)

 

Check Junction box adhesive for cracks or cracks. 

b)

 

Check the connector interface sealing and whether there is loose, melt deformation, aging or corrode. 

c)

 

Check that the cable connections are secure and that the modules are properly grounded. 

      When  module  is  found  to  be  defective,  consult  a  qualified  service  technician.  If  servicing  is  required,  it 

should be serviced by a qualified service technician. Module exposure generates high voltages in the sun, so 

cover the modules with opaque material when servicing modules to prevent electrical shock. 

Note:

If using maintenance and repair measures not included in this manual, consult your local dealer for professional support.
