Solar firm reaches 30% module efficiency

Circadian Solar, the concentrated photovoltaic (CPV) systems supplier, has achieved a temperature-corrected peak module aperture efficiency of 30% during trials at its test site in Lisbon. The efficiency result continues to be reproduced with a number of different modules over the course of the trials.
Circadian Solar has been testing its system, which is designed for optimum performance in sunbelt regions, at the University of Lisbon since June 2010. These trials complement the Company's module evaluation programme that was set up in Cyprus in late 2008. A further test site is being established in the Middle East, as part of the Company's plan to demonstrate cost effective energy yield in different regions and environments.
 Focusing on the design at the full system level ensures that the CPV modules work most efficiently as part of the complete system. Integral to this has been the Company's proprietary tracker, which demonstrates outstanding accuracy, even under high wind loading. The company expects to announce results of its system testing in early 2011.
