6�1 Maintenance Plan
Unqualified personnel treading on the roof
Mortal danger!
• Any work that requires stepping onto the roof may only be carried out by specialist personnel.
Falls due to working without personal protective equipment against falls (PPEAF)
Mortal danger!
The installation of the photovoltaic system is only permitted with collective protection. However, certain work may also be
carried out before the installation with PPEAF (checking the existing building structure, taking measurements), and likewise
maintenance work on the installed photovoltaic system. When work is carried out using PPEAF:
• Only allow personnel who are trained in its use to carry out work using PPEAF.
• Only use regulation PPEAF including lanyards with energy absorbers.
• Permit no personnel to work alone using PPEAF
• The persons present in the workplace must always be able to rescue persons using PPEAF with their own equipment (even
hanging for only a few minutes in the safety harness carries the risk of permanent injury!).
• Installation work is only permissible with collective protection (scaffoldings, roof guard rails) in accordance with the local
regulations.
Slipping on damp roofs that are covered in algae, moss or soiled by other means
Danger of injury!
• Before stepping onto roofs that are covered with dew, allow them to dry off
• Descend immediately from roofs that are soiled if it starts to rain
6 MAINTENANCE
When
What
Who
After exceptional meteorological events, but
at least once a year
Visual inspection
No special requirements
Quarterly
Yield check
No special requirements
If yield declines significantly
Check the PV array with an infrared camera
Specialist personnel,
alternatively: Operator with relevant equip-
ment and competence
If PV array soiled for instance fallen leaves
Spray off the leaves with a water jet from the
ground
No special requirements
6�2 Replacing Modules
1. Shift the module to the left of the defective module upwards until it detaches from the mounting clamps on the bottom
edge (when replacing modules on the left-hand edge of the PV array, the flashing profile must be pushed upwards).
2. Lift up the right-hand corner of the module to the left of the defective module by about 3 to 5 cm and secure the module
in this position using a wooden wedge.
3. Shift the defective module upwards until it detaches from the mounting clamps on the bottom edge.
4. Lift up the defective module by the bottom edge and pull it downward and out.
5. Disconnect the connections to the neighbouring modules in the string and secure the loose cable ends of the neighbouring
modules so that these do not “disappear” down between the PV array and the roof underlay.
6. Disconnect the grounding cable and secure the loose cable end so that grounding continues to be pro-vided for all
remaining modules.
7. Remove the defective module.
8. Connect the grounding cable to the replacement module.
9. Establish connections to the neighbouring modules in the string.
10. Mount the replacement module under the raised module or the flashing profile left beside it, push it under the module
above it (at the top edge of the PV array: under the side flashing) until it clicks into place and lower it.
11. Pull the replacement module downwards until it clicks into place into the bottom mounting clamps.
12. Remove the wooden wedge under the right-hand bottom corner of the module to the left of the replacement module.
13. Pull the module or the flashing profile left beside the replacement module downwards until it clicks into place into the
bottom mounting clamps.
7 DEINSTALLATION AND DISPOSAL
Incorrect handling because of insufficient qualification and expertise.
Danger of severe injuries!
• Deinstallation and disposal of PV systems may only be carried out by qualified specialist firms.
• Commission only a specialist firm for in-roof photovoltaic systems to carry out deinstallation and disposal.
