Mare Flex
flexible, lightweight, solar module, for the use with rechargeable
batteries
This manual includes information about safety, operation,
capacity and maintenance of the module, as well as technical
instructions which you should make yourself familiar with before
you use your solar panel! Please read these instructions
carefully before installation!
Safety Warnings
This manual does not list all precautions needed for safe
work. Follow local guidelines.
Modules may not be folded or creased during handling and
storage
Folding and excessive bending will cause cracks and
internal short circuits which will create locally over currents
causing overheat and melting the encapsulation materials
Voltage of a single module is not dangerous
Never connect more than 3 modules in series
Work under dry conditions with dry tools
Modules exposed to sunlight produce DC electricity. Live
parts may cause electric shock. Avoid contact with the metal
terminal leads in order to reduce the risk of electrical shock
Use electrically insulated tools when wiring modules
Connect your system in a carefully vented environment and
make sure there are no highly inflammable gases or vapours
existing
Observe proper polarity when connecting the module into an
electrical circuit. Reverse connection will damage the module
and may result in fire and/or personal injury. The cables are
marked with the polarity (+ red / - black)
Do not use non-rechargeable batteries!
Please observe during work with batteries and electrical
equipment the industrial standards and safety instructions of
respective manufacturers!
Avoid partially shading modules under load to prevent hot
spots and/or reduction in power.
Artificially concentrated sunlight shall not be directed onto
the module.
Do not carry the module by the wires.
Do not cut, scratch, or puncture the Module.
Do not stand or walk on the module.
Do not immerse unconnected connectors in liquid
Do not drop or allow objects to fall onto the Module.
Do not attempt to open, or otherwise dismantle the junction
box
Installation
1. Choose an appropriate position to assemble your panel on a
solid surface. If the surface is not stable and could be deformed
the module can be damaged by cells cracks.
2. if you glue the module it is
important to avoid closed
chambers. Water will stay in those
chambers for a long time and can
freeze in winter. Increasing volume
of ice can bend module locally and
cause cell cracks.
If you glue in serpentines water can escape. The distance of the
turns should be about 8 to 12 cm.
The turns should be pulled across
the module from one edge to the
other. The turns should cover the
module from the top to the bottom.
3. never bend the module more
than 2,5
% of length. the hight “h”
should be max. 2,5% of length of
the module. see also diagram 1
4. Fix the module in a position that ensures the cell surface is
inclined towards the sun and choose a location where the solar
module is able to absorb as much sunlight as possible. Direct
the panel to the south side to achieve the best possible
charging performance.
5. Connect the solar panel over a charge controller (not
included in delivery) with your battery. Refer to the manual of
the charge controller for installation instructions.
Special care must be taken to ensure that the module and the
underground cannot swing!
Swinging and bending cause cell cracks and damage to
the module!
Reverse connection will damage the module and may result
in fire and/or personal injury
Do not immerse the module under water
Cleaning
Clean module surfaces only with alcohol, window cleaner, or a
mild soap & water solution and a lint-free cloth
Do not use any aggressive cleansing agents or solvents since
they may damage the module. Neither use any pointed, or
sharp-edged items on it since they might damage the panel
surface!
