Grass et al. membandingkan kolektor

Grass et al. membandingkan kolektor konsentrator parabolik non-Tracking dengan dua kolektor tracker: sebuah parabolic trough dan kolektor tabung dengan integrasi tracker reflektor. Tracking dilakukan dengan menggunakan satu sumbu sistem trackingmagnetik. Pada analisa Ray-tracking, mereka menggunakan kode Ray-tracking ASAP (Breault Research Organization Inc, 1999). Untuk menentukan efisiensi optik untuk radiasi langsung dan difusi serta pengubah sudut insiden kolektor, pengukuran dilakukan di dekat suhu sekitar. Hasilnya menunjukkan bahwa efisiensi optik untuk radiasi langsung dapat ditingkatkan pada siang hari dengan menggunakan sistem tracker. Namun, kesalahan kecil tracking dapat memiliki efek yang signifikan, jika sudut langkah kecil.

Grass et al. comparing collector parabolic concentrators non-Tracking with two collectors tracker: a parabolic trough and tube collectors with reflector tracker integration. Tracking is done by using a single axis trackingmagnetik system. At Ray-tracking analysis, they use Ray-tracking code ASAP (Breault Research Organization Inc., 1999). To determine the optical efficiency of direct and diffuse radiation and incident angle modifiers collectors, measurements carried out near ambient temperature. The results show that the optical efficiency can be improved for the direct radiation during the day by using a tracker system. However, a small tracking errors can have a significant effect, if a small step angle.

Grass et al. compares non-Tracking parabolic concentrator collector with two collector tracker: a parabolic trough and a tube collector with the integration of a reflector tracker. Tracking is done using a single axis trackingmagnetic system. In Ray-tracking analysis, they used the SMOKE Ray-tracking code (Breault Research Organization Inc, 1999). To determine the optical efficiency for direct radiation and diffusion as well as collector incident angle modifiers, measurements are carried out near the ambient temperature. The results showed that the optical efficiency for direct radiation could be improved during the day using a tracker system. However, a minor tracking error can have a significant effect, if the angle of the step is small.
