Circadian Solar achieves world-class CPV module efficiency results

Coventry, UK – 16th December 2010 – 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.

Circadian Solar has achieved the world-class DC module efficiency by adopting its Ultra Power Density approach, in which all aspects of system design are engineered holistically to deliver the lowest possible cost of electricity generated. 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.

CEO of Circadian Solar, Jeroen Haberland, said, "The achievement of 30% module aperture efficiency is a significant milestone for us and we are seeing rapid progress in the development of our world-class CPV systems. Delivering high efficiency, reliable electricity at an affordable cost level is of the utmost importance to us, and the latest efficiency result demonstrates that exceptional efficiencies can be delivered without sacrificing affordability. Ultimately, optimum cost-per-kilowatt hour is the value that we will deliver with our CPV systems.”

Circadian Solar’s testing is expected to continue into mid-2011 as the company builds up to manufacture.
