serious injury. The end user must keep these safety instructions.
•
The installation, control, commissioning, maintenance and repair of the installation must only
be carried out by qualified personnel.
•
The correct functioning of the installation is only guaranteed if the installation and assembly
have been carried out in accordance with the rules of the art.
CAUTION
•
The entire solar installation must be installed and operated in accordance with recognized
technical rules.
•
All electrical work must be done according to local guidelines.
•
The installation must not be used if it shows signs of damage.
DANGER
•
For installations on roofs, it is necessary to comply with personal safety standards, relating to
roofing and waterproofing work and relating to scaffolding work with safety net by mounting the
respective devices before starting work . Refer to the recommendation published by the national
risk prevention organization.
•
Gloves are compulsory when handling the panels to avoid any risk of injury or burns.
•
Disconnect all connection cables from the power supply before working on the installation.
1.2.

General recommendations
2.1.1.
Handling
INAA modules should be handled like any glass product. To avoid accidents, injuries, or damage
to the module during work, the following precautions must always be observed:
•
Do not step on the modules.
•
Do not drop anything on the modules.
•
Protect the modules from possible scratches on the front and rear sides
•
Do not exert mechanical tension on the connectors.
•
Always lift and transport the modules with both hands and never use the junction box as a
carrying handle.
2.1.2.
Transport
In order not to risk damaging the modules during transport, the following instructions must be
observed:
•
Transport the stacked modules vertically, with a separator supported by the frame of each module.
•
Do not remove the original packaging until the time of installation.
•
Do not apply mechanical pressure to the modules (for example, do not fasten the modules with a
strap, or else do not place any object on the surface of the modules).
2.1.3.
Storage
During storage, to avoid any accident or damage to the modules, the following instructions must be
observed:
•
Store the modules vertically.
•
Do not store modules on the edges, on a corner, or on an uneven surface.
•
Do not place any object on the surface of the modules.
•
When choosing a suitable storage location, make sure that:
The location is dry and cool,
No object can fall on the module and thus damage it.
WARNING
If a INAA module is damaged or broken, it must be replaced. Never install a damaged module.

Technical considerations
Throughout the year, the system is exposed to external weather and natural conditions (sun, wind,
rain, hail, snow, thunderstorms, dead leaves, dust, bird droppings, etc.) which influence the
performance and service life of the modules. To extend the service life of the modules and ensure
proper operation of the installation, important factors and adjustment parameters must be
considered:
2.3
Angle of inclination
The optimal mounting position of the INAA solar panels corresponds to an angle of incidence of the
sun's rays of 90
°
relative to the surface of the panels (i.e. perpendicular to the panels). To optimize
the output of the installation, the panels must be installed with the optimal orientation and angle of
inclination. These positioning angles depend on the geographic location of the installation and can
be calculated by a qualified solar installer. Wherever possible, the panels of a group must have the
same orientation and the same inclination in order to avoid any underperformance of the system due
to inconsistent productions
INAA recommends a minimum tilt angle of 5 ° from the horizontal to reduce the clogging
effect.
The cleaning frequency should be increased for modules installed with a very low angle of
inclination from the horizontal..
2.4
Wind and snow load
The module has been tested up to a pressure of 5400 Pa negative pressure (snow) and 2400 Pa
in positive or negative pressure (wind) without damage. It thus meets the requirements of
standard IEC / EN 61215 for wind speeds up to 130 km / h.
2.5
System location
The overall yield of the photovoltaic system in series is always limited by the module delivering
the lowest power. Different factors can influence the performance of a module (shading,
different orientations, fouling ...) and these impact the entire system.
Therefore, it is necessary to study the layout to avoid a shading effect on the modules in series.
In addition, all panels must be mounted with the same orientation. It is advisable to align all the
modules to the solar noon, to obtain optimal performance.
INAA suggests installing the modules in areas where the temperatures are between -20 ℃ and
+ 50 ℃,which corresponds to the minimum and maximum monthly average temperatures, in
accordance with IEC 60364-5-51. The extreme operating temperatures of the modules are between -
40 ℃and + 85 ℃.
In regions with heavy snow cover and exposed to strong winds, the modules must be mounted in
such a way as to ensure sufficient nominal resistance and in accordance with local regulations.
Certain operating environments are not recommended for INAA modules, and are excluded from
the INAA Limited Warranty:
•
No panel should be mounted on a site where it may be exposed to direct contact with :
•
salt water
•
acid rain
•
active chemical vapors or any other aggressive environment
•
INAA modules must not be installed near flammable liquids, gases, hazardous materials or on
any type of vehicle.
•
Maximum design altitude of the photovoltaic module ≤2000m.
