northern hemisphere. Use the included Allen wrench to tighten the set
screw and lock the Solar Panel onto the mounting pipe.
g. The panel should be angled to receive the maximum amount of light
during the day. To move panel loosen the hinge bolt and rotate the
panel into position, then retighten the bolt. The angle depends on the
panel’s location, see following table:
Latitude of site Tilt angle
0-4°
10°
5-20° Add 5° to local latitude
21-45° Add 10° to local latitude
45-65° Add 15° to local latitude
65-75° 80°
Table for fixed angle above horizontal for solar panel.
At most latitudes the panel’s performance can be improved during the
winter by setting the panel to a steeper angle and during the summer
by setting the panel at a flatter angle.
If the panel will not be cleaned regularly Global Water recommends
that they not be mounted at an angle flatter than 15°. Flatter angles
will not be cleaned properly by rainfall.

h. The Solar Panel comes with a blocking diode installed (internally in the
SP101) to prevent the attached device from reversing the current
polarity on the solar panel.
i. The Solar Panel should be attached to the battery or appliance using
tight connections. Use terminal connectors or if splicing the wire
solder it together for a solid connection. The red or striped black wire
is positive and the black wire is negative. The panel should be
connected to the device with matching polarities.
