The Southern Nevada Water Authority contracted with Amonix, Inc. in 2008 to procure 220 kWdc of their latest generation multi-junction cell High Concentration Photovoltaic system. This paper describes the installation of the six HCPV systems including the design layout of the field, installation of the foundations, the PV modules, and tracking control systems. In addition, the basic operation and features of the Amonix HCPV system are discussed, along with data showing the performance of each system since the start of operation.
The Southern Nevada Water Authority contracted with Amonix, Inc. in 2008 to procure 220 kWdc of their latest generation multi-junction cell High Concentration Photovoltaic systems (HCPV). This paper discusses the performance of the six HCPV systems that started operating in mid 2009. Data sets included show: a. Daily power performance; b. Power performance compared to the specified performance; c. Effect of field shading upon the daily power performance. What is demonstrated is the system power performance has not degraded during this initial period of operation and continues to meet or exceed the specified performance levels.
