Amonix CPV solar power plants

In 2008 and 2009, Amonix installed 300 kW of its seventh-generation systems in Las Vegas, USA. Use of III-V multijunction cells resulted in a ~30% reduction in the cost of energy of Amonix CPV solar power plants. AC system efficiencies currently reach 25% and energy yield is over 2500 kW-hr/kW. A performance model has been developed that predicts system output based on the spectral response of the III-V multijunction cell corrected for operating conditions. This model is used to inform ongoing system optimization. Systems installed in 2010 are expected to deliver over 10% more power and energy.
