Solar Systems has more than 10 years experience with grid-connected CPV systems using large reflective optics. Over the last 7 years, Solar Systems has deployed 47 dish units, of which 23 are with multijunction solar cells, in five different commercial CPV power plants and two testing facilities, for a total installed capacity of 1.5 MWp. Recently, Solar Systems has designed and built a 140kWp Heliostat Concentrator PV (HCPV) system at its new Testing and Training Facility in Bridgewater, Victoria. The demonstration of the performance of the HCPV system met all the specification targets. The system reached a power output of 140kW with a DC efficiency of 240/0 to 260/0 and an optical efficiency of 840/0, measured on two different days, four months apart, around solar noon. This is the first utility-scale Heliostat CPV system ever built. It is also for Solar Systems the first demonstration of a new technology to be deployed in a large 154-MWp power plant in Northern Victoria.
