First Solar has signed an agreement with Strata Solar, a utility-scale solar project developer and builder in the U.S.,for the procurement of an incremental 400MWdc of First Solar’s advanced thin film PV modules, with delivery expected from 2017 into 2018. With the agreement, Strata will have purchased more than 1,000 MWdc from First Solar.

“We are pleased to be extending our relationship with First Solar,” said Markus Willem, CEO of Strata Solar. “Strata has a relentless focus on quality, efficiency, and flawless execution, so it’s critical for us to have world-class technology partners like First Solar.”

“This deal shows confidence in the continued strength of the utility-scale solar market in the U.S.,” said Georges Antoun, First Solar’s President, U.S. “We are excited by Strata’s ongoing commitment to First Solar as a source of high-performance technology that provides a competitive edge in their project portfolio.”

Antoun said the agreement demonstrates the sustainability of utility-scale project development. “We see ongoing opportunity for continued growth over the next several years,” he said. He further noted that First Solar has now sold more than 1.8GW of modules in the U.S. Southeast, with modules either sold to outside developers, EPC contractors, or used in First Solar’s own projects.

Strata expects to install the modules in a series of solar projects in the southern and eastern U.S.
