Amonix CPV Modules Hit 36 Percent Conversion Efficiency


Amonix Inc., a designer and manufacturer of concentrating photovoltaic (CPV) solar power systems, says it has achieved a conversion ratio of 36% with its latest-generation CPV technology.

The solar system had been in outdoor testing since late February. During this period, the Amonix module demonstrated a peak operating efficiency of 36.2% measured on March 14, 2013, with a DNI of 876 W/m2, an ambient temperature of 16 degrees C and instantaneous wind speed of 1 m/s, breaking the previous 34.2% peak efficiency set by Amonix in May 2012.

Over the entire testing period, the Amonix module earned a National Renewable Energy Laboratory (NREL) outdoor efficiency rating of 34.9%, a new world record, under international standard operating conditions for concentrator photovoltaics of 900 W/m2, 20 degree C ambient temperature and 2m/s wind speed, breaking the previous 33.5% rated efficiency record also set by Amonix in May 2012.

The module uses Boeing Spectrolab 40% high efficiency solar cells and Amonix's proprietary CPV technology.
