  • OAT one axis tracking
  • One way of increasing the efficiency of OAT solar collectors is through improving the angular radiation efficiency which is defined as the ratio between the solar radiation intensity received at a surface and between the radiation intensity received at the surface when it faces exactly in the sun's direction. Accordingly, in case of a parabolic reflector or a Fresnel's concentrator, when the sun's rays strike parallel to an optical axis of the reflecting or concentrating surface, then, the angular radiation efficiency is maximal.
  • tracking means are to be provided for tracking the sun as it progresses in the sky.
  • One kind of tracking systems known is the two axis tracking systems, However, due to complexity of the two-axes tracking systems, they arc usually applicable to parabolic dishes supported by a substantially tall single leg. Rotating a parabolic trough-like collector in two axes is practical only for short and narrow collectors, since in large collectors there may be severe problems such as torsion of the reflector giving rise to poor optic performances and various torsion forces which may even cause damage to the heat collection element (HCE).
