PV technology is quite different from the flat-plate PV modules sold around the world. CPV units come in larger module sizes (typically 20 to 35 kW), track the sun during the day, and are more suitable for large installations. In 2004, less than 1 megawatt (MW) of concentrator PV systems was installed, out of a total world PV market of 1200 MW. Admittedly, 1 MW does not constitute significant market entry. However, the significant development is an increased number of projects with sizes of several hundred kilowatts (kW), creating a market appropriate for CPV technology. And CPV technologies are ready today for this market opportunity with high-efficiency solar cells and well-developed hardware. But it is the near-term prospects for even better performance and lower installed system costs that are leading to real market entry during 2005 and 2006. Amonix, Inc., of Torrance, California, spent more than 15 years developing five generations of CPV prototypes that led to the products most recently installed in Arizona by Arizona Public Service (Figure 1
