It should point:
due north - for the southern hemisphere or
due south - for the northern hemisphere.
The panel should be angled to suit the sites latitude
and season so that the sun shines at right angles to the
face of the solar panel. In normal applications fixed
setting of the unit to 45° from horizontal should
suffice. For more efficiency the panel can be angled
typically to 60° from horizontal in winter and 30°
from horizontal in summer. The solar panel bracket
has slots cut into the side to assist in setting these
angles.
Access Tubes
The access tubes should be positioned to provide the
best representation of the site to be monitored.
See the appropriate Installation Manual for details on
installation of the access tubes and top caps.
Top Caps
See the Access Tube Installation Manual for details
on installation of the access tubes and top caps.
Cabling
External Power
Joining Cables
The length of the cable supplied with the solar panel
should be sufficient for normal applications. If
alternative external power sources are to be
connected to the unit or the solar panel cable needs to
be extended then the cable to be used is a 2 core
sheathed cable with 16/0.3mm conductors.
The following describes the method used for
extending cable if greater distance is required or a
repair is necessary.
1.
Insert the cables into the junction box and pull
through enough cable to make joining easy
(approx 50cm).
2. Strip back the outer sheath so that 5cm of inner
wires are exposed.
