First Solar has agreed to supply thin film modules totaling 231.6 MW in direct (DC) to a subsidiary of Silicon Ranch.

The modules will be installed as part of several solar projects that will be built in 2017 and early 2018.

First Solar expects to deliver the first batch of modules in the first quarter of next year.

Earlier, the companies signed an agreement that requires First Solar to deliver over 180MW of DC modules for projects entering commercial operations in 2015 and 2016.

The projects are situated in Colorado, Georgia, Mississippi, Arkansas and Tennessee.

The deals also require First Solar to deploy own balance of system solutions such as its single-axis tracker for some projects.

First Solar said its thin film technology demonstrated advantages when compared to conventional multicrystalline silicon (mc-Si) solar products in all regions of the world, particularly in the hot, humid climates that make up a major portion of Silicon Ranch’s project footprint.

First Solar vice president of US business development Roger Bredder said: "There is deep value in aligning with a trusted, major solar developer, and our previous endeavors with Silicon Ranch have allowed us to jointly benefit from working in a region with exciting growth opportunities."

Silicon Ranch chief technology officer Pete Candelaria said: "First Solar is a U.S. manufacturer with superior products and a strong balance sheet, all of which were important factors in our selection.

"Furthermore, their technical and logistics units are the best in the business, which made them a great fit for the Silicon Ranch team."
