6.9 Solar panel installation
FIGURE 6-42. Solar panel mounting and cabling
1. Mount the solar panel to the pole using the mounting brackets ( FIGURE 6-42 (p. 59)).
2. Mount the solar panel to the pole so it faces south (northern hemisphere). Position it as
high off the ground as practical, ensuring it cannot interfere with air flow or sunlight around
the sensors. The solar panel should be oriented to receive maximum insolation over the
course of the year. Suggested tilt angles referenced to the horizontal plane (
FIGURE 6-43
(p. 60)) are listed in Table 6-1 (p. 59).
