2. General description
2.1 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.

2.2 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.

6.5 Venting of the solar installation
After venting the solar installation by means of a filling station and a manual
air escape you should close the air escape valve, in case of an automatic air
escape it is necessary to close the ball valve.
6.6 Insulation work
Insulation work should be done after performing all inspection operations.
Directions!
– High temperature and weather resistant insulation must be used to insulate
the conduits which are outside the building. If necessary, protect the
insulation against damage caused by birds.
– High temperature resistant insulation must be used to insulate the conduits
inside the building
6.7 Maintenance and Service
During the maintenance and other kind of work a collector must be placed firmly to exclude the
danger of tripping over and falling down,
It is not allowed to perform any repair and maintenance work under a lifted collector which has
not been protected against casual falling down,
Repair and maintenance work should be done by means of suitable tools and the servicing
personnel should wear protective gloves and shoes,
6.4Filling up the installation by using a filling station
1. Filling station (9): Connect the hose (1) with the upper valve (3), hose (2)with the bottom valve (4).
2. Fill up the tank of the filling station with the liquid, open the valve (3 and 4) and run the pump.
3. Closing the valve (5) will cause the flow through the solar collectors.During filling and venting the
system, you should several times open andclose the vent (5).
4. Do not turn off the pump until the installation will be completely vent -until from the hose stop
flowing air bubbles.
5. Open the vent (5) and close the vent (4) and still pump the fluid until the installation will reach the
required pressure, p = 2.5 bar - Pressure measurement (6).
6. Turn on the controller plug (7) to the network and enable ~ 230V circulation pump in manual mode.
7. Remnants of the air should be removed automatically by unscrewing the valve manually
8. In case of decrease or absence of flow unscrew the central screw in the circulating pump and let the
air exhale. Do this exercise until full vent installation.
9. In the case of pressure drop on the Pressure measurement (6) below 1.5 bar complete up to the to
the required pressure p=2.5 bar.
10. Disconnect the hose from the filling station from the valves (3, 4)
Before the commencement of maintenance work it is necessary to wait till the temperature of a
collector lowers to such an extent that a risk of getting scalded by hot elements is excluded,
Overhaul of the solar system needs to be done in accordance with warranty recommendations f
or particular elements of the system.
In order to guarantee failure-free operation of the whole system it is recommended to carry out
the following maintenance work at least once a year:
Frost protection – check the solar fluid resistance to frost by means of a control device
(refractometer). In case of a significant fall in frost resistance of the solar fluid it should be
replaced and the system must be deaerated once again.
System pressure – working pressure in the solar system needs to be checked. After the start-up
period no drop of pressure is permissible.
Expansion vessel –input pressure of the expansion vessel should be checked. To this end,
disconnect the vessel from the system and measure the pressure.
The input pressure should be 2.5 bars.
The control and protection system should also be inspected along with the structure for
supporting and fixing a collector on the roof.
