I. Item Checklist
a. Solar Panel
b. Solar Panel Manual
II. Inspection
a. Your Solar Panel was carefully inspected and certified by our Quality
Assurance Team before shipping. If any damage has occurred during
shipping, please notify Global Water Instrumentation, Inc. and file a
claim with the carrier involved.
Use the checklist to ensure that you have received everything needed
to operate the Solar Panel.
III. Installation
Precautions
Global Water
800-876-1172 • globalw.com
a. The Solar Panel is designed for rugged use, however it must be
handled with care. Front and rear impacts can damage the panel.
b. The panel should not be flexed or bent.
c. There are no user serviceable components inside the housing.
d. Light should not be concentrated on the panel to increase the power
output.
Location and Placement
e. The Solar Panel should be located in an area where it is free of
shading for the majority of the day, particularly during midday when the
unit is most productive.
f. The Solar Panel comes with mounting hardware that will allow the unit
to be attached to a 1” pipe. The pipe may be mounted horizontally or
vertically. For best results the face of the panel should be pointed true
north if you are in the southern hemisphere and true south if in the

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.
Electrical
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.

VI. Maintenance
a. Global Water recommends inspecting the panel once every 6 months
to verify the connections are still good and there is no corrosion on the
contacts.
b. The panel should be cleaned periodically. Dirt and dust will reduce the
power output of the panel. Gently clean the surface with a soft cloth or
sponge using water and a mild detergent. Do not scrub the surface
using a brush or abrasive material this may damage the face. Please
take care, since the unit generates direct current and the potential for
shocks is present.
