APS STAR Center, West Field Site

There are currently 145 kW in operation in the West field at the APS STAR facility in Tempe, Arizona. The field now consists of three 25 kW units and two 35 kW units. Initially there were three 20 kW units and three 25 kW units as shown in Figure 8. The MegaModules from the three 20 kW units were moved to a new 35 kW drive system. These units were installed during the period from 2000 to 2003 and represent different versions and configurations as the design matured. The 35 kW units, incorporating 7 MegaModules, are the latest design to be manufactured and installed at this site. The units in the west field have produced over 1,185 MWh of grid power since the start of operation.
