INSTALLATION AND OPERATION MANUAL CRYSTALLINE SOLAR MODULES Q-CELLS SE - AUSTRALIA
Observe the following when selecting and using connection lines and connectors:
• Only use solar cables as connection cables. Use connectors of the same type and manu-
facturer within a solar system, and compatible connectors to connect the inverter.
• Ensure that all electrical components are in a proper, dry and safe condition. In this way
you avoid electrical short-circuits or dangerous contact voltages due to defective or dam-
aged cables.
• Always avoid mechanical stressing of the connection cables.
• Ensure a tight connection between the individual connectors (especially to the inverter).
Make sure they click together properly.
Upon completion of the installation, ensure that:
• the wiring is protected from dirt and moisture.
• the plug connections do not lie on a water-channeling surface and are properly connected.
• all necessary safety and functional tests have been carried out according to the current
state of technology.
Q-Cells modules are built to last and require minimal maintenance. Light dirt is typically
washed away by rain. However, rain may not adequately clear more stubborn grime (i.e. pollen,
vegetation, bird droppings, etc.). Such soiling which shades the active area of the module can
lead to a reduction in the system‘s performance.
WARNING! Danger of injury from heated and live modules!
Only clean the modules when the module temperature lies between 10 °C and 30 °C, e.g. in
the early morning or late evening. Do not wear electrically conductive parts.
WARNING! Risk of falling during maintenance of roof installations and building-integrated installations!
Never enter the installation area alone and unsecured. We recommend commissioning a spe-
cialist company to perform this work. Consult your installer on location.
As the operator, you should regularly remove dirt built up from the modules. In addition to the
safety instructions and chapter 3, observe the following points:
• Never step on the modules. Do not subject the modules to mechanical stress.
• Avoid cleaning with water when there is a danger of frost and strong temperature
differences between the module, water and air.
• Hard water used as a cleaning agent should be decalcified beforehand in order to avoid
water staining. Remove any standing water from the module.
• Do not use abrasive detergents or surface-active agents (e.g. soap). Do not scratch dirt off.
This can damage the surface of the module.
Only remove snow and ice without exerting force (e.g. with a broom).
Proceed as follows to remove dirt from the
top of the module:
1. Rinse coarse dirt (dust, leaves, etc.) from the module with lukewarm water.
2. Moisten stubborn stains and remove them carefully.
Use lukewarm water and a soft cloth or sponge. If necessary, it is possible to use isopropanol
(IPA)
selectively. Follow the safety instructions on the IPA packaging. Ensure that the IPA does
not run off between the module and the frame or into the module edges.
