• Optimum Orientation and Tilt
To achieve the maximum annual yield gure out what the optimum orientation
and tilt of the PV modules is. If sunlight shines vertical onto the PV modules you
have the best conditions to generate maximum power.
• Avoid Overshadowing
Even the slightest partial shading (e.g. from dirt deposits) will cause a reduction
in yield. A module is considered “shadow-free” if it is unobscured across its entire
surface for the whole year and even on the shortest day of the year unobstructed
sunlight can reach the module.
• Reliable Ventilation
Functioning ventilation prevents the build-up of heat, which would reduce
performance.
• Earthing
Although the modules are certied to safety class II, we still recommend earthing
them. The earth connection must be made by a qualied electrician.
Connect module frames to each other using cables with cable lugs. Use the hole
(Φ7*11mm) attached that are provided for this purpose. To create the conductive
connection (frame is anodized), use a serrated washer or a self-tapping screw
(Φ5.5mm). The earth connection should be made by a qualied electrician.
All the junctions on the conductive connection must be xed.
The fastness does not depend on soldering.
The metal containing iron in the conductive connection should be handled by
some way, such as anodization, spray-painting, galvanization.
Stainless steel does not need to be handled.
