A new configuration of V-trough concentrator for achieving improved concentration ratio of >3.0x

A new configuration of V-trough solar concentrator is proposed, constructed and investigated in an attempt to improve the concentration ratio of the V-trough concentrators. The new design consists of two conventional V-trough concentrators arranged in a cross, which lead to improvement in concentration ratio and angular response. The results of an experimental study show that the concentration ratio of this new configuration (referred to as OVSC) is 40%-60% higher than its corresponding conventional V-trough solar concentrator (CVSC) with additional benefits. The study reveals that the angular response of this new configuration is better than conventional V-tough concentrator with a potential to reduce the cost of concentrators by using less reflector materials. Surprisingly, the improvement in the concentration ratio is not accompanied by significant reduction in optical efficiency and light uniformity, making it a better alternative for low-cost and low con-centration applications in future.

A new configuration of V-trough solar concentrator, consisting of two conventional V-trough concentrators arranged in a cross, has been proposed to improve concentration ratio and angular response. Experimental results show a 40%-60% increase in concentration ratio compared to the conventional V-trough solar concentrator, with no significant reduction in optical efficiency and light uniformity. It has potential for low-cost and low concentration applications.
