For operators: maintenance
Inspect and maintain your system to:
• Keep it safe and reliable
• Achieve top output
• Prevent damage and
• Protect your investment.
It is recommended to carry out regular inspections
and to do maintenance so that any problems can be
discovered reliably, and rectified.
RECOMMENDATION
• It is recommended to do annual inspections
and a more thorough inspection and measurement
every 4 years.
• It is also recommended to use a monitoring system
to identify any outages or problems quickly.
• Inspecting the output of your photovoltaic system
regularly can help to discover problems promptly,
and ensures your photovoltaic system operates at
top performance, preventing loss of output.
For the proper maintenance and repair of your solar
photovoltaic system, contact installer.

The inspection includes the following aspects.
8.1.1 Inspecting the generator
• Strings: condition of the insulation and mounting
• Condition of the junction box
• Condition of the visible connectors
• Condition of the earthing conductors
• for direct earthing: connection of the earthing
conductors on the frames
• for indirect earthing: connection of the frames to
the sub-structure and the earthing conductors to
the sub-structure
• Condition of the mounting system (in peripheral
area)
• Dirt on modules: type and degree of dirt
• Shade circumstances (e.g. from trees or
neighbouring houses)
Clean the components, if necessary.
8.1.2
Inspecting the documentation and drawings
• Checking the PV module string plan
• Check the inverter's status reports
