The visual inspection of the modules

 

 

The purpose is to detect 

any:

  

  

 

Tears of glass.  

 

Deteriorations interior of the seal watertight the module 

GruppoSTG Fabbrica Srl

.

 

 

Oxidations  of  the  circuits  and  of  the  welds  of  photovoltaic  cells  for  the  most  part  due  to 
moisture  in  the  form 

GruppoSTG  Fabbrica  Srl 

in  following  the  rupture  of  the  layers  of  the 

housing in the phases of installation and of transport. 

 
 

Control of the connections and the wiring

 

 

Every 6 months or so, do a maintenance preventive :  

  

 

Check the mounting and the state of the terminals of the cables for connecting the modules. 

 

 

Check the seal sealed the box of terminals. 

 

 

If necessary, check the electrical characteristics of the 

GruppoSTG Fabbrica Srl 

module . 

 

 

In the event that you they spot problems of seal watertight, it is necessary to replace the elements concerned and  
carry out the cleaning of terminals.  

  

It is essential to cure the sealing of the box of the terminals, using, in the second of the case, joints new or a 
sealant to silicone
