The Agua Caliente Solar Project is a 290 megawatt (MW) photovoltaic power station, built in Yuma County, Arizona using thin-film technology based CdTe PV panels manufactured by First Solar.[2] The project was completed in April 2014.[3][4]


39 MW was online as of December 2011 and 100 MW was completed as of April 2012.[5] 200 MW was completed as of July 2012,[6] and 247 MW in August 2012, when the 10th section was completed. The addition of more panels has halted until 2013, with crates of panels covered to protect them.[7]

Project overview[edit]

In August 2011, the Department of Energy finalized a $967 million loan guarantee for the project. The project sponsor, NRG Solar, estimates the photovoltaic generation facility will fund approximately 400 construction jobs and 16 full-time operating jobs, and will be one of the largest plants of its kind in the world when completed.[8] The power produced will be sold to PG&E (Pacific Gas & Electric) in California in a 25 year Power Purchase Agreement.[1][9]

The Series 3 thin film panels use CdS/CdTe,[10] and are rated from 75 watts to 77 watts each, and are mounted at a fixed tilt angle. 20,940 are connected in each array, rated at 1.26 MWAC, and over 400 SMA 720CP inverters are used. Two inverters are connected to each array.[11]


In February 2012, Agua Caliente competed in the Excellence in Renewable Energy Awards and won Project of the Year Award.[9]
