Developer Swinerton Renewable Energy has signed a deal to use the latest trackers from Array Technologies on a 1GW pipeline of US PV plant projects.

The tracker manufacturer announced yesterday that over a dozen utility-scale projects will be built in various regions, using the DuraTrack HZ v3, which Array claims is a “groundbreaking design built to lower the levelised cost of electricity”.

As of June, when a 40MW supply deal for two plants in California was announced, the two companies had worked together on 270MW of solar installations, with yesterday’s announcement therefore representing a significant scaling up of the partnership.

Array Technologies, the solar market’s leader for tracker sales, has seen 3GW of its trackers installed worldwide. The company claims DuraTrack HZ v3 needs no scheduled maintenance over its 30-year expected lifetime and has a 6% power density advantage over rivals.

“Its advancements will allow us to provide the lowest installed cost tracker in the industry,” Swinerton Renewable Energy vice president and division manager George Hershman said of the single-axis tracker.

“ATI’s high reliability and low maintenance costs provide our clients the best overall plant performance. Swinerton is proud to be a long-term partner with ATI and we look forward to successfully delivering our 1GW portfolio together.”

Array Technologies CEO Ron Corio meanwhile talked up the company’s partnership with Swinerton.

“Our partnership is based on a mutual interest to increase the dissemination of solar by lowering LCOE and improving its economic viability. We are honored to work with such a well-respected organisation and believe that the experienced team at Swinerton proves to be a superior asset to the solar industry,” Corio said.

Corio recently said that Array had expanded manufacturing output and increased automation at its production lines in order to meet an expected surge in demand for utility-scale system components as the US solar industry readies itself for the likely scaling down of the investment tax credit (ITC) support in December 2016.
