The STI-H250™, solar tracker model selected for these facilities, "is ideal for challenging projects", explains Ignacio Irureta, STI Norland project manager. "Dual-row trackers are designed to adapt to uneven terrains and ground contours, optimizing the use of available land and increasing power generation". A special technical feature of this project of that STI-H250™ solar trackers employ a tracking logic which enhances performance on cloudy days. This logic was developed and successfully tested in previous projects supplied by STI Norland. These solar trackers are also equipped with large photovoltaic panels which enable in-series connection of 38 modules. To do that, STI Norland designed a solution to inter-connect solar modules from different trackers or different rows of the same tracker.
