On 3 May 2012, Duke Energy Renewables announced the purchase of a 10 MW single-axis tracker photovoltaic (PV) system under development in Arizona, US. This project is one of over 160 MW of single-axis tracker PV systems installed or under development in Arizona since 2011. Ninety percent of single-axis tracking projects are located in the US Southwest. Key trends in this On Point include: Tracking differentiates utility-scale PV players from fixed-tilt solutions. Trackers augment the US Southwest's solar resource advantage. Uncertainty over long-term O&M costs casts shadow on tracking advantage. Cost advantage reduced in lower-resource areas.
