N2 - We report progress towards developing methods to forecast solar-power intermittency due to clouds using analysis of digital images taken with a ground-based, sun-tracking camera. We show preliminary results of block-motion estimation analysis applied to a sequence of sky images recorded in Tucson, Arizona. In addition, we discuss statistics of ramp rates and duration of cloud-induced intermittency based on the analysis of one year of photovoltaic power output data measured at one-second intervals for a 2-kW system.
