DESIGNING AND PERFORMANCE ANALYSIS OF SOLAR TRACKING SYSTEM FOR A PARABOLIC TROUGH
Keywords:
Solar parabolic trough, Solar-tracking device, electronic circuit, DC motor.Abstract
An active type solar trekking system is developed for a novel modular sized parabolic trough. The system contains a pair of photo resistors that are connected into a wheat stone bridge circuit that operates a dc motor. Static balancing of the support structure was done after finding the centre of gravity through a 3-D CRE-O software to minimise the trekking power. The Tracking System is a hardware and software prototype, which will provide alignment of the trough with respect to sun for getting maximum output. Performance analysis of the device was made under clear sky conditions.
