SP70 Solar Panel
3.3 Orientation
The solar panel should be oriented to receive maximum insolation (incident
solar radiation) over the course of a year. Suggested tilt angles of the solar
panel are given in Table 2.
After determining the tilt angle, loosen the 5/16" nuts on each side of the solar
panel, and reposition the Hex bolt locations according to the hole location
settings shown in Table 3 to adjust the panel. Tighten the two nuts to secure
the position. See Figure 16.
TABLE 2. Solar Panel Tilt Angle*
Site Latitude (N or S) Tilt Angle
0 − 10° 10°
11 − 20° Latitude +5 °
21 − 45 Latitude +10 °
46 − 65 Latitude +15 °
> 65 80 °
