The solar panel panel, integrated with the C3+ Solar Enclosure, can be set to one of three angles (30, 40, and 50 degrees as measured from horizontal). The panel can only fully lock into place when seated at one of these angles. An indication of the position can be seen by the index marks on the rear of the enclosure. The angle should be set to optimize solar exposure during the winter months. A guide for a given latitude (South or North) is to set the angle to:
- 30° when in latitudes between 0° and 30°.
- 40° when in latitudes between 20° and 30°.
- 50° when in latitudes greater than 30.
Note that in the southern hemisphere the enclosure must be oriented with the panel facing true north. In the northern hemisphere, the panel must face true south.
