Dirt could be:

• D ust, pollen or seed

• L eaves or twigs

• D eposits from stable vapour

• M oss, algae, fungi or bacteria growing on depo

sits (in short: biofilms)

• S alt (in coastal regions)

11.4.1 Safety precautions

CAUTION!

Contact of live parts with water. Risk of electric

shock!

• N ever use a high pressure cleaner.

NOTE

You will also retain the manufacturer's warranty as a

result of this measure.

11.4.2 Glass surfaces

NOTE

• 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 demineralised

water if possible.

• Avoid the use of acids, bases or other aggressive

cleaning agents.

Distilled or demineralised water is often used by cleaning services but can damage

glass surfaces with frequent intensive use over long periods of time. aleo solar there

fore advises against the use of distilled or demineralised water.

NOTE

Dirt- or water-repellent coatings subsequently ap-

plied to the modules can negatively affect the effici-

ency of the aleo modules and therefore the power

output of the whole photovoltaic system. We the-

refore advise against the use of these agents.

RECOMMENDATION

For cleaning the glass module surfaces, aleo solar

recommends:

• Rainwater without additives

matching the temperature of the module.

• A soft sponge or a soft brush.

• If necessary, use a telescopic rod with a sponge or

soft brush attached on the end. The rod can have a

water pipe integrated.

• 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 recommends 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 measurable effect on

the module output and fade away after about 2 weeks of

being exposed to weather conditions, as sunlight and rain

break them down.

11.4.3 Insulating back sheet

The insulating back sheet must not be cleaned. Neverthel-

ess, if you still need to perform work behind the modules

(e.g. to remove leaves):

• Make sure you refer to Ch. 6.2.1: „Electrical safety

precautions" and Ch. 6.2.2: „Mechanical safety pre-

cautions".

• Avoid damaging the insulating back sheet.

Rainwater has a low level of water hardness. It is beneficial to use it because a build up of

deposits is avoided.

This prevents mechanical tension in the glass and ensures the module a longer service life.

Ethanol contains denaturants. Some denaturants can leave streaks behind or damage

an anti-reflex layer.
