We went looking for photovoltaic installations that were either utility-scale ground-mount systems or smaller roof-top installations. We found those, plus a little of everything in between:

City of Madera wastewater treatment facility

The City of Madera’s wastewater treatment plant is one of the city’s largest utility buildings, and its vast energy needs cost Madera millions of dollars in maintenance annually. In an effort to reduce electricity costs for taxpayers and make use of abundant land while achieving sustainability initiatives, the City of Madera commissioned REC Solar to develop a 1.1MW solar installation with dual-axis tracking for the wastewater facility. This makes it one of the nation’s largest dual-axis tracker systems. Design and construction began in early 2010, and the system was completed in August 2010.
