The panel must face south in the Northern Hemisphere and north in the Southern Hemisphere.
Table 1. Recommended tilt angle for solar panelTo maximize the annual energy output, tilt the panel towards the sun at the recommended angle. The further you are from the Equator, the more vertical the panel must be.

In some installations, it can be effective to adjust the tilt seasonally. To improve the solar panel performance during summer at most latitudes, use an angle smaller than recommended. Conversely, a larger angle can improve the performance during winter.
  1. Slightly loosen the adjusting screws.
    CAUTION Be careful not to damage the power cable.
