Installation and Operating Guide
AUS240729 7
Water drainage openings in the module frame must not be closed in any way. The mounting frame,
too, must not obstruct them. The earthing holes provided only serve for the purpose of earthing the
frame.
4.2 Site selection
Marine and mobile applications are generally excluded. Floating installations only after consultation
with AXITEC.
If the modules are assembled near the sea, a minimum distance of 500 m to the coastline must be
ensured.
Solar modules may not be installed above 2,000 m above sea level.
Glare caused by modules cannot be ruled out. Modules must therefore not be installed in locations
where glare could pose a potential risk.
Operation of the solar modules in regions with snow loads of up to 3600 Pa is dependent on the
assembly and module type (see 5. Mechanical installation).
The modules must be installed in an environment in which it is ensured that the operating
temperature range will not exceed or fall below -40°C to +85°C. Sufficient air circulation behind the
modules should particularly be ensured in hot environments.
All shading of the module array is to be avoided. The modules must not be permanently shaded
(including partial shading, spot shading, uniform shading or uneven shading). Permanent shading
means that the cells are continuously shaded over a longer period of time, e.g. when modules are
installed behind a pipe, a chimney, a tree, etc. If a defect (e.g. a hot spot) is caused by improper
installation of a module in the shade or by poor maintenance, the warranty is void. The power loss
in fully or partially shaded cells leads to power loss, reduced yield and can lead to localized
overheating, which in turn can have a negative effect on the service life of the modules. Permanent
shading can lead to accelerated ageing of the encapsulation material and cause thermal stress on
the bypass diodes. If modules are nevertheless installed in such shaded areas, optimizers are
required at module level (MLPE).
