Handling and Fitting Manual for semi-flexible solar panels EFLX series
Page 11 of 12
To fit a solar panel with a rear junction box:
•
Most rear junction box solar panels come with a round junction box. Drill a round,
appropriately sized hole into the mounting surface (typically 30 mm) so that the
rear junction box fits well.
•
Place the solar panel on a soft, non-abrasive surface with the rear side facing
upwards, and apply the adhesive in beads as described above.
•
Apply a thick adhesive ring (at least 12mm line diameter) around the junction box
to form a closed seal around it, and bond the solar panel to the surface.
•
Two people are recommended to perform this installation.
As per the guidance above, to avoid trapped air forming underneath the panel,
do not
seal the edges of the solar panel
with adhesive.
V. Electrical connection
Warning!
This product generates electrical current when the front side is exposed to
light. Even if the voltage and current from a single solar panel is low, multiple solar panel
connected in the same circuit can have a much greater voltage and current. Touching
the terminals or wiring may cause an electric shock or burns. To avoid risks, fit an isolator
switch for solar panels or cover them during the installation.
When connecting the solar panel(s) to a solar charge controller, remember that most solar
charge controllers require a battery connection first, so that they can detect the battery
voltage and condition, before they start taking power from the solar panel. So the solar
panel(s) should be connected to the solar charge controller after the battery connection
has been made live.
Always observe general safety standards, specifications and manuals of the connected
equipment, as well as the installation advice below:
•
Do not use different types or sizes of solar panels in the same system, unless your
installation has been preapproved by your supplier or another qualified person.
•
Do not modify the electrical connections of the solar panels. In particular, do not
open or remove the junction box.
•
Do not cut or pierce the solar panels, as this may cause live components to
become exposed and/or damaged.
•
Any installation or maintenance of solar panels must take place in dry weather on
dry surfaces.
•
Use tools with insulated grips only.
•
Do not use damaged solar panels (including damages received in transit or during
the installation).
•
Do not apply any protection covers, coating, paint or varnish to the solar panels.
•
Do not drop heavy or sharp items onto the solar panels.
•
Do not concentrate sunlight (e.g. from mirrors or lenses) or other sources of
artificial light on the solar panels.
•
Do not install solar panels in locations where they may be submerged in water for
lengthy periods.
