2. General description
2.1. Technical characteristics
The technical characteristics of the DualSun panels can be found in the technical sheets published in our -
online library
2.2. General recommendations
2.2.1. Handling
DualSun 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.
For the complete deconditioning and handling procedure for DualSun modules, see DualSun sheet No. 04-78.
2.2.2. 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).
2.2.3. 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 DualSun module is damaged or broken, it must be replaced. Never install a damaged mod-
ule.
2.3. 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
Installation, use, maintenance manual DualSun FLASH

of the modules. To extend the service life of the modules and ensure proper operation of the installation, impor-
tant factors and adjustment parameters must be considered:
2.3.1. Static roofing requirements
The solar installer must ensure that the roof structure can carry the additional weight of the hybrid system.
2.3.2. Angle of inclination
The optimal mounting position of the DualSun 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.
DualSun 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.
2.3.3. 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.
2.3.4. System location
The overall yield of the photovoltaic system in series is always limited by the module delivering the lowest pow-
er. 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.
DualSun suggests installing the modules in areas where the temperatures are between -20 ° C and + 50 ° C,
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 ° C and + 85 ° C.
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 DualSun modules, and are excluded from the Dual-
Sun 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
• DualSun 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

2.3.5. Types of mounting
The fastening of the modules must be secured by at least 4 points and spread according to the areas specified
in the diagram Installation areas on the rails of the mounting system [10]
In-roof assembly
This assembly guarantees the retention of the original functionality of the roof. Special attention should be paid
to the insulation as well as to the protection against rain and humidity. To achieve this level of sealing, the mod-
ule must be mounted on a special frame that can route rainwater and withstand the wind and snow loads occur-
ring in the geographical area of the installation.
On-roof assembly
The modules can be mounted on a frame designed to support the photovoltaic panels. This framework must be
able to withstand the wind and snow loads occurring in the geographical area of the installation. When fasten-
ing and connecting the system to the building, it is necessary to avoid damage or destruction of the roof cover-
ing in order to maintain optimum resistance against rain and moisture.
WARNING
The instructions given in the installation guide for the mounting system must be followed for
proper installation.
2.3.6. Protection against fire / explosion
Do not install the DualSun modules in the vicinity of highly flammable gases, vapours, or dust (e.g., next to a
gas station or containers). The national and local fire prevention standards and regulations must be respected
during installation. For installations located on a roof, the modules must be mounted on a fire-resistant roofing
cover adapted to the application.
The DualSun modules have a fire resistance of class C according to standard IEC / EN 61730-2.

Assembly specifications [10]
CAUTION
The management and installation of DualSun panels and the equipment making up the com-
plete installation must be carried out by trained and qualified personnel. The system must be
assembled and operated in accordance with the instructions provided, in accordance with the
local and national health and safety, and risk prevention regulations.
During assembly and operation of the system, no unauthorized person may be on the
roof or around the installation.
3.1. Installing DualSun modules
DualSun panels can be installed both in portrait and in landscape.
DualSun does not provide the mounting system for fastening the modules on the roof: please refer to the instal-
lation instructions of the chosen mounting system, to install the modules whether for an integrated or for a su-
perimposed installation, in landscape or portrait.
NOTE
The list of mounting systems compatible with DualSun modules is available in the “Mounting
systems compatibility" document in our online library
CAUTION
Even when solar radiation is low, the photovoltaic system produces direct current (DC). This
DC current flows from the module to the inverter, do not handle the module or connections
without protection.
The modules are qualified for use in class II and comply with standards IEC / EN 61215-2 and
IEC / EN 61730-1. These standards concern PV modules for use on buildings, or on ground
structures.
Artificially concentrated solar radiation must not be directed onto the module.
The frame thickness and the dimensions of the SPRING panel are identical to photovoltaic panels. It adapts
easily to photovoltaic mounting systems; however, it is necessary to ensure the positioning of the hoses in rela-
tion to the mounting system frame and to the roof covering surface.

The mounting system must have a flat surface for mounting the panel and must not cause twisting or stress on
the panel, even in case of thermal expansion.
We also remind that the waterproofing of the roof is not ensured by the panels but by the panels mounting sys-
tem and that the drainage must be provided.
It is necessary to provide a space between the frame of the panels and the structure or the floor to avoid dam-
age to the cables and hydraulic fittings.
The panel mounting systems must be installed only on buildings that have been formally validated for structural
integrity, and which have been considered capable of supporting the additional weight of the panels and mount-
ing systems, by a certified building specialist or engineer.
The supplier of the mounting system must take into account the galvanic corrosion which may appear between
the aluminium frame of the panels and the mounting system or the grounding parts if they are made of different
metals.
The module is only certified when its original frame is completely intact. Do not remove or modify the module
frame in any way. Drilling additional mounting holes is likely to damage the module and reduce the strength of
the frame, and thus is not allowed.
The use of flanges and fasteners with additional grounding bolts or grounding connectors shall be in accord-
ance with this safety and installation instruction manual and according to the conditions of Grounding and light-
ning protection [14].
The modules can be installed according to the following methods:
1. Frame holes: Attach the module to the structure using the factory-made mounting holes. It is recommen-
ded to use four M8x16 mm stainless steel screws with bolts, washers and lock washers for each module.
The maximum tightening torque of the bolts is 24 N.m.
2. Calipers or clamps : the brackets can be mounted on the longitudinal (longest side) or lateral (shortest
side) side of the module. The areas allocated to these clamps are specified in Installation areas on the rails
of the mounting system [10].
Installers must ensure that the resistance of the clamps is sufficient given the maximum pressure to which
the module can be exposed. The clamps are not supplied by DualSun.
IMPORTANT
It is important to make sure that the clamping brackets do not distort the top of the aluminium
frame of the DualSun panel, this may weaken or even break the glass.
CAUTION
The tightening torque of the clamps must not exceed 24 N.m.
WARNING
The compatibility of the mounting system with the modules must be assessed before any in-
stallation, especially when the system does not use brackets or clamps.
