Array Technologies has supplied the ‘Mount Signal’ 265MW solar plant in Calexico, California with its Dura Track HZ solar tracking system.
Array Technologies was awarded the tracking supply contract in November 2012. The 265MW project is said to be the largest tracking system for thin-film installed in the world, to date.
The project uses thin-film panels manufactured by First Solar, and is being constructed by Abengoa.
Using 1,300 delivery trucks to deliver the tracker system, Array Technologies completed the shipment several weeks early, but was challenged with the thin-film panels’ frameless design, so used a unique patent-pending bowed tracker rack. Array Technologies said using the specifically designed bow-truss solution saved on labour and material requirements for a speedier installation.
In August, Array Technologies also provided 170MW of Dura Track HZ for the ‘Centinela Solar' project, constructed by Fluor, with Yingli modules; the solar plant is also near Calexico, California.
