About a month ago, the title of largest operational U.S. photovoltaic plant belonged to the 55-MW (DC) Sempra Copper Mountain solar facility in Boulder City, Nev., about 40 miles southeast of Las Vegas, which boasted 775,000 First Solar (Nasdaq:FSLR) solar panels.
That is so "last month."
The crown heralding the largest operational PV plant in North America now belongs to the 100 MW on-line of the 290-MW Agua Caliente solar project in Yuma County, Ariz..
Construction is still in progress, with completion expected in 2014.
