Abstract
The construction details and the performance characteristics of
a Parabolic Trough Solar Collector system are presented in this
paper. Two main items of the system are presented namely; the
collector and the tracking mechanism. From the results obtained
the collector performance equation is given by:
n = 0.642 - 0.441 (~T/I)
The collector time constant is equal to 30 sec and its half acceptance
angle is 0.5°. The tracking mechanism proved to be
very reliable and accurate. Its maximum error is 0.2°.
From all the above results it can concluded that the
Parabolic Trough Collector System is a viable means for
harnessing solar energy.
