Precautionary measures
5.13.1.
Facade or overhead installation
WARNING
Only use aleo modules for roof or free-field
installation.
Do not use aleo modules for facade or
overhead installation.
5.13.2.
Structural analysis
WARNING
Perform the necessary verifications for the building or
property or have the following carried out by
professionals:
load capacity verification
structural integrity verification,
usability verification (deflection under load
verification).
See also the following literature references: [6], [7], [8],
[9], [10], [11], [12], [13], [14], [15] and [16].
CAUTION
Take into account the expected snow loads
and wind forces at the location.
With respect to the structural analysis of the
overall building, take into account the
additional loads created by the photovoltaic
system. Remember, in elevated systems, e.g.
on a flat roof, snow or ice may accumulate
behind the modules.
5.13.3.
Fire protection
WARNING
The solar modules as well as the sub-
structure may affect the level of the
building’s fire resistance.
Improper installation may create an
additional risk in the event of a fire and when
measures are undertaken to extinguish a
fire.
Determine and follow the relevant require-
ments of authorities, energy supply compa-
nies, insurance companies and fire services
as during the planning phase of the photo-
voltaic system and definitely prior to the
start of installation.
Install PV system components (e.g. inverters)
away from business premises at risk of fire
([45]). Select a different, permitted location.
When planning, please also take into account
the additional fire prevention components
that are recommended, necessary or requi-
red, such as fire prevention switches, direct
current fuses and/or short-circuit
monitoring.
Fire prevention switch
RECOMMENDATION
aleo solar recommends the installation of a double
fire prevention switch between each string of the
PV generator and the corresponding inverter con-
nection. Local, national or international regulations
may require a fire prevention switch.
Install the fire protection switch so that it is easily
accessible and at the point at which cables from
the photovoltaic generator enter the building. This
allows the current for the direct current devices of
the photovoltaic system to be switched off inside
the building.
Please note that direct current cables directly con-
nected to the inverter may still be live for some time
after disconnection from the photovoltaic generator
(see also Ch. 6.2.3, 'Precautionary measures in
inverters').
