10. Maintenance
When properly assembled, the Sigma S1 is a reliable
and trouble-free system that requires minimal
maintenance. Nevertheless, S-Rack Australia Pty
Ltd recommends performing regular inspections
and creating a maintenance schedule. By doing so,
potential problems can be detected and resolved
before they can become serious, ensuring the
system’s excellent long -term durability and
reliability.
The following procedure pertains only to the Sigma
S1 System structure. Maintenance and repair of
other PV system components should be carried out
in accord
ance with the respective manufacturers’
recommendations.
9.1. Inspection
The system should be visually inspected for obvious
loose connections, missing components, modules
which appear to have shifted, vegetation
overgrowth, wind-blown debris, and other
indications of abnormality annually. Any problems
detected at this time should be addressed and
repaired as necessary.
9.2. Testing
After one year in service, it is good practice to check
the torque settings of a representative sample of
system connections including module clamps and
rail clamps. Do not exceed the recommended
torque settings. If a disproportionate number of
loose connections (more than 10% of connections)
are found, it may be an indication of an improper
assembly and it may be necessary to take
comprehensive corrective action.
S-Rack Australia Pty Ltd recommends keeping
records of connections sampled each year and
checking untested connections in the succeeding
years. Once all connections have been tested,
sample sizes and test frequency can be reduced.
