8 For operators: maintenance
Inspect and maintain your system to:
• Keep it safe and reliable
• Achieve top output
• Prevent damage and protect your investment.
8.1 Inspections
An inspection every year is recommended. This
should be a visual inspection. Refer to Ch. 8.3: „Details
for the inspections“.
8.1.1 Inspecting the generator
• Strings: condition of the insulation and mounting
• Condition of the junction box and the visible connectors
• 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
• 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 6,
• Check the inverter's status reports
• Determine and archive the annual output
• Create and archive the inspection report.
8.2 Review
Carrying out a thorough review at least every 4 years is
recommended. This includes the following work in
addition to the inspection:
• Measure the characteristics of individual strings
(MPP current IMPP, open-circuit voltage UOC, power
output PMPP);
