COMMISSION AND MAINTENANCE
5.1
BLOCKING DIODES AND BYPASS DIODES
Blocking diodes prevent current flowing from the battery to the module when no electricity is being generated. It is
recommended to use blocking diodes when a charging regulator is not used. Your specialist dealer can advise you
regarding the suitable types.
In systems with more than two modules in series, high reverse current can flow through cells that are shaded partially
or outright when part of a module is shaded and the rest is exposed to the sun. These currents can cause the affected
cells to get very hot and could even damage the module. To protect module from such high reverse currents, by-pass
diodes are used in modules. All modules rated greater than 55 Watt have bypass diodes already integrated in the
junction box. In the unlikely event of diode failure, it can be easily replaced; however, doing so will void warranty
unless this exchange is made by an authorized person.
Protect yourself from electric shocks while debugging or maintaining the solar power system.
5.2
TROUBLESHOOTING
DANGER! Life danger due to electric shock!
Please do not attempt to correct problems on your own!
In case of problems or damaged modules (for example, glass breakage, damaged cables)
please contact your installer or the Talesun Technical Customer Service.
5.3
MAINTENANCE
Talesun modules are built to last and require minimal maintenance. The dirt is typically washed away by rain. However, rain
may not adequately clear more stubborn grime (i.e. pollen, vegetation, bird droppings, etc.). Such soiling which shades the
active area of the module can lead to a reduction in the system‘s performance. Talesun recommends the following
maintenance in order to ensure optimum performance of the module:
Clean the glass surface of the module as necessary. Always use water and a soft sponge or cloth for cleaning. A mild,
non-abrasive cleaning agent can be used to remove stubborn dirt.
Check the electrical and mechanical connections every six months to verify that they are clean, secure and undamaged.
If any problem arises, have them investigated by a competent specialist. Attention: observe the maintenance
instructions for all components used in the system, such as support frames, charging regulators, inverters, batteries
etc.
