This orientation does not optimize the amount of sunlight.
- Ideally, the direction of the sunlight needs to be perpendicular to the collector at all time in order to obtain the maximum sunlight.
- That is the reason why tracking system are developed.
- The tracking system, however, has two main disadvantages compared to a fix mount.
1. High cost and 2.Maintenance
- Therefore, a fix position system can still be seen widely because of its cheapness and lower maintenance problem.
