Solar SCADA systems need to take advantage of the great repetition intrinsic in solar plant design. This paper presents several key facets of a SCADA system designed specifically for utility scale solar generating assets. The presented SCADA system gathers and stores approximately 400 points per MW of installed photovoltaic generating capacity. This paper discusses both the hardware and software architecture of this SCADA system including design choices related to point types and the data system used to aggregate the information. Means and methods of data analysis are presented to enable rapid responses to forced AC and DC outages in concert with JSI's utility partners.
