FIGURE 6-40. Solar panel mounting and cabling
1. Mount the solar panel to the pole using the mounting brackets (
(p. 53)).
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

the course of the year. Suggested tilt angles referenced to the horizontal plane (
(p. 54)) are listed in
