Abstract

Parabolic trough solar collector is providing nonpolluting energy for domestic and industrial application. Assessment of profile of manufactured parabola by precise instrument is basic need for high efficiency. This paper presented the assessment of parabolic profile by two dimensional linear scales having right angle to each other and compared the results with the analytical equation. Graphical view also presented for results measured by linear scales and analytical equation. The efficiency of the solar trough also can be increased by installing thermocouples at periphery of the receiver tube.
