6.2    Connector and Cable Inspection

6.2.1

         Check if all cables are securely connected.
 It is suggested that all cables shouldrunin 
proper cable ducts and should be located 
away from the water-prone area.

6.2.2

         Check the electrical, grounding, and 
mechanical connections every 6 months to 
ensure that they are clean, safe, free from 
damage, and rust-free; ensure that the 
mountings properly tightened; check all 
cables to make sure they are tight.

6.2.3

         It is forbidden to use WD-40 or various 
organic solvents to wipe all parts of the
junction boxes, wires, and connectors.

6.1.1

         Maintenance should be carried out at 
least once a year by trained person. A s 
system voltage is so high, that maintenance 
person should always wear rubber gloves 
and insulated boots. Removing all possible 
shading of the solar array, which would affect
power generation of the module array.

6.1.5

        Cover the front surface of Modules with an 
opaque material. Modules exposed under the sun 
could be extremely dangerous, as high voltages 
could be generated.

6.1.6

       Module junction boxes is equipped with bypass 
diodes to minimize module heating and current loss

6.1.2

         Check if the installed hardware is securely 
in place.

6.1.3

         Check if all array fuses in each of the 
non-grounded poles are working properly.

6.1.4

         If module is damaged (glass breakage 
or scratches on the back glass), it is need 

to be replaced. Module must be  replaced 
with same type one. Do not touch the live 
parts of the cables or connectors when 
replacing modules. Use appropriate safety 
guards (insulation tools, insulated gloves, 
insulated boots, etc.) when handling modules.

         Modules in array should be regularly 
inspected to check damage modules. If 
damage module is founded, it must be 
replaced with same type one. Such as broken 
glass, broken cables, damaged junction box, 
etc., which would lead to functional and safety 
failure of modules.

         Well-designed solar systems require 
minimal maintenance, and some simple steps 
could be taken to improve system performance 
and reliability.
