Handling and Fitting Manual for semi-flexible solar panels EFLX series

Important!
For difficult shaped roofs where a rebounding motion of the solar panel is
likely, use other means to secure the solar panel in place while the adhesive dries. This
may involve using weights (distributed evenly across the solar panel) or tape. If you
decide to use tape, ensure that no residual glue is left on the solar panel surface after
you remove the tape.
After bonding with adhesive,
do not seal the edges of the solar panel
. The solar panel
must be kept breathable underneath to allow any air to escape.
If multiple solar panels are mounted on the same surface, or if the edges of the solar
panel are close to other objects (such as a roof skylight), leave a gap between the solar
panels (or between the solar panel and nearby objects) of at least 2mm to compensate
for the linear expansion of material under different temperatures.
Important!
If mounting a solar panel on a non-horizontal façade or a difficult mounting
surface (e.g. glass, wood, concrete, brick, canvas etc.) the instructions provided above
are not applicable. Please seek special guidance for installations of this nature.
Drilling, screwing and riveting
Mounting by self-tapping screws or securing the solar panel with fasteners via mounting
holes are both good methods of fitting the solar panel which help eliminate the risk of
trapped sealed air under the solar panel. To secure a solar panel using one of these
methods:
•
Mounting holes can be drilled into the corners of the solar panel and along the
long edges in gaps between the solar cells corners.
•
Holes should be positioned at least 8 mm away from the solar cells.
•
Holes should be sealed with an adhesive after mounting to avoid the risk of
future delamination of the solar panel material.
Mounting with Velcro tape
Fitting the solar panel using strips of Velcro tape helps avoid the risk of trapped sealed
air underneath the solar panel. However this method is not recommended for vehicles
and speedboats due to the wind drag which might force the solar panel to detach.
Once the solar panel has been mounted with Velcro tape, it should be treated as a
permanent installation. Attempting to remove the solar panel, particularly if a large part of
or the entire back surface is covered with Velcro, can seriously damage the solar panel.
Fitting a solar panel with the rear junction box
If your solar panel features the junction box on the underside (JBB sub-series), we do not
recommend using a double-sided adhesive tape to mount it, especially on uneven
surfaces with irregularities. This is because it will be harder to ensure that the cable entry
hole under the solar panel is fully waterproof. Please use a suitable adhesive instead.
