Visual precautionary measures
NOTICE
Do not artificially concentrate or directly reflect
sunlight on an aleo module. Do not use any lenses or
mirrors.
If your photovoltaic generator is located in an area with strong
reflections (e.g. due to snow or areas of water) then the maxi-
mum performance of the photovoltaic generator may be
increased. This is non-critical for aleo modules.
However, please take this situation in consideration when
dimensioning and selecting your inverter (see Ch. 5.11.
‘Matching of solar modules and inverters’).
5.6.
Selection of aleo modules
Select the aleo module type that is best-suited to your con-
crete system. A main distinguishing feature among modules is
whether they are made from mono or poly-crystalline cells.
Which cell type is best-suited to your needs depends on your
goals and expectations.
The following general rules can make this decision easier:
Mono-crystalline cells have:
an octagonal shape (square with bevelled
corners)
a black base colour. - this base colour can
vary depending on the actual cell being used.
Poly-crystalline cells have:
a square shape
a bluish base colour - this base colour can
also vary depending on the actual cell being
used.

NOTICE
Only use modules of the same type, the same cell
type, and the same output class within a module
string. Doing so will optimise your energy yield.
If you connect numerous module strings to an MPP
tracker in parallel, make absolutely sure that you
use the same number of modules for every one of
the module strings connected in parallel.
Deviating from this procedure can have a significant
effect on the output of a photovoltaic system,
increase the risk of damage, and reduce the service
life of the modules.
Information on how to match aleo modules and inverters can
be found in Ch.
5.11, '
Matching of solar modules and
inverters
'.
