ANY FAULTS
Thanks to rigorous controls of quality that are undergoing the modules Photovoltaic first to be put on sale,
failures are very infrequent.
It can , however, verify the cases of which below, due however to causes unrelated to the process of
manufacture:
Breakage of the glass of the modules.
Penetration of moisture within the modules
Faults connecting the modules to the system.
Shadow effect
Breakage of the glass
Glass breaking generally occurs as a result of external actions: breakage during transport to the
construction site, due to erroneous installations , impacts, throwing stones, etc.
The breaking of the tempered glass always occurs in the form of total chipping of the surface,
clearly highlighting the point of impact.
In addition to reducing performance, chipping can create dangerous conditions for electrical insulation.
Even if the
GruppoSTG Fabbrica Srl
module will continue to function, it is
absolutely
necessary
to
change
the
GruppoSTG Fabbrica Srl
module as soon as possible in order to guarantee both safety for people and
things and the operation of the system.
Penetration of humidity inside the modules
and relative oxidation of the internal circuit of the cells and of
the connection welds .
Even if it is an infrequent failure, it can occur as a result of bumps and scratches on the rear insulating
sheet due to external aggressions . When moisture penetrates up to the circuit of cells and the relative
connections, gives rise to corrosion that reduce and even come to break the electrical contact of the
electrodes with the material of the cells, preventing the collection of electrons and inutilizzando so the
GruppoSTG Fabbrica Srl
module.
The voltage and intensity are reset and the
GruppoSTG Fabbrica Srl
module must be promptly replaced.
If, in a revision are detected serious deterioration of the module
GruppoSTG Fabbrica Srl
, it is preferable
to provide for its replacement.
Faults in the system for connecting the modules
Date the excursion thermal, for eg., between the day and the night, you can verify a loosening of the
connectors of the wiring of the modules. For this reason, it must be inspected regularly (for eg., In
cadence biannual) the connections, providing to a their clamping if necessary.
