2.3.9.3.2 Tilt Angle
30/40 Watt Solar Panel Systems (see Figure 2-35) have adjustable tilt angles. Table 2-17
shows the angle (from horizontal) at which the Solar Panel should be installed in order to
maximize annual energy output. At most latitudes, performance can be improved by less of
an angle during the summer and more of an angle during the winter.

2.3.9.4 Installing the Rechargeable Battery and Solar Panel Harness
The Rechargeable Sealed Lead-acid Battery must be removed from its shipping carton and
installed on its mounting bracket within the enclosure as illustrated in Figure 2-36.
