In May of this year, the National Renewable Energy Laboratory (NREL) confirmed an outdoor operating efficiency rating of 33.5% for an Amonix module, breaking the previous 30.3% record also held by Amonix. Over several days of on-sun testing conducted by NREL, the module efficiency peaked at 34.2%. This is the highest efficiency ever reported under real-world, operating conditions for a solar PV module.
