solar photovoltaic system, contact your aleo solar

2.2: „Contact").

9 .2 Inspections

aleo solar recommends an inspection every year.The
inspection includes the following aspects.
9.2.1 Inspecting the generator
• strings: condition of the insulation and mounting
• condition of the junction box
• condition of the visible connectors
• condition of the mounting system
• dirt on modules: type and degree of dirt
• shade circumstances (e.g. from trees or neigh-
bouring houses)

9 .3 Cleaning

Depending on the ambient conditions, modules are
likely to get soiled more or less heavily over time. This
can cause reduced output.
Dirt could be:
• dust, pollen or seed
• leaves or twigs
• deposits from stable vapour
• moss, algae, fungi or bacteria growing on
• depo sits (in short: biofilms)
• salt (in coastal regions)
9.3.1 Safety precautions
Contact of live parts with water.
Risk of electric shock!
Never use a high pressure cleaner.
You will also retain the manufacturer's warranty as a
result of this measure.

9.3.2 Glass surfaces
The glass surfaces of aleo modules have microscopic
structures or anti-reflex coatings. Ensure that these
do not get damaged. Do not use any cleaning agents
which will polish or scratch the surface.
Avoid the use of very hard water.
Also avoid the use of distilled or demineralized water
if possible.
Avoid the use of acids, bases or other aggressive
cleaning agents.
Dirt- or water-repellent coatings subsequently applied
to the modules can negatively affect the efficiency of
the aleo modules and therefore the power output of
the whole photovoltaic system. We therefore advise
against the use of these agents.
RECOMMENDATION
For cleaning the glass module surfaces,
aleo solar recommends:
• rainwater without additives with its temperature
• a soft sponge or a soft brush
• If necessary, use a telescopic rod with a sponge or
For stubborn patches of dirt, use the following to help:
Isopropanol: aleo solar recommends a mixture of
isopropanol and rainwater to the ratio of 1:1
Glass cleaner: As an alternative, aleo solar recom-
mends clear, colourless glass cleaner with no ethanol
or denaturants (e.g. Bitrex®).
Anti-reflex glass
aleo modules have an anti-reflex layer on the glass
surface to achieve a higher output. This means that
some marks (e.g. fingerprints) are more visible than
on normal glass. These marks are mostly seen as
shimmering patches.
These kinds of marks do not have any
