Cleaning The Surface Of The Modules; Decommissioning The Installation; Disassembling A Module - DUALSUN M-60-3BBP Serie Manual De Instalación, Uso Y Mantenimiento

6 Cleaning the surface of the modules

The higher the level of contamination of the PV system surface, the less the cells are able to absorb the energy
contained by the incident sunlight.
By tilting slightly, the panels relative to the horizontal, the rain and snow can clean the surface, and thus temporarily
protect them from additional contamination. However, after a while, dust, leaves or bird droppings will salt the glass
in front and thus reduce the output power.
In case of persistent soiling, the panels must be washed with cold water and a soft sponge.
Never use solvents or a pressure washer, and never scrape the surface of the panel. Cleaning operations
must be carried out by qualified professionals.

7 Decommissioning the installation

Before any operation on the appliance/installation, the power supply and the injection must be switched off (e.g. via
the appropriate fuse or a general switch) and to prevent any re-operation.
For any intervention involving disassembly of the regulations, make sure that the internal components are not likely
to cause a static discharge.

7.1 Disassembling a module

If it proves necessary to disassemble a module, the following procedure must be followed:
Drain the installation (see DualSun instructions – Installation and commissioning of a pressurised system and
•
Swimming pool system installation).
•
Turn off the electrical circuit upstream and downstream of the inverter.
•
Risk of electrocution. Refer to the inverter/micro-inverter manufacturer's manual for this. It may be necessary
to use a particular disconnection tool. Disconnect the module from its support.
•
Unplug the electrical connectors.
•
Unplug the grounding module.
•
Disconnect the quick fittings of the inter-panel links, see chapter 7.2.
•
If this is the last module that is removed from the installation, the temperature probe must also be dismantled,
see chapter 5.2.
