First Solar Stops Installation at Agua Caliente Project

First Solar Inc., the biggest U.S. solar manufacturer, halted panel deliveries to the world’s largest photovoltaic power plant, which it’s building in Arizona, because construction is ahead of schedule and the company must slow down to meet contractual milestones.

First Solar won’t ship additional modules until January to the $1.8 billion Agua Caliente project and won’t install panels currently sitting on the ground at the site, said Fred Pech, the power plant’s construction manager. The solar farm is scheduled for completion at the end of 2013 and is 85 percent built.
