Antaisolar, the first in the list, is also a new company to the survey, not to the market though. The company’s TAI-Space tracker, which the company says represents a diverse catalog of trackers so that the right configuration can be chosen for the right terrain and corresponding layout. As per the data, TAI-Space has a maximum length of 240 m, accommodating 210 modules in 1P configuration. It has a ground coverage ratio of 25 to 45%. The system features electric synchronized with multi-point drive powered by a self-powered DC brushless motor. In addition to the powering from the string, the company also supports supplying power from an inverter or an AC motor. It supports a moving range of +/- 60°. The tracker is governed by the Solar Position Algorithm (SPA) and recommends stowing at 5° facing the wind. TAI-Space supports various foundation types—concrete with flange, concentrate with pile and ramming, while W8 Sections are used for driving post and C-Shaped steel is used for general post All the trackers of the company are designed based on the results from the CPP wind tunnel studies, including aeroelastic study for instabilities. Antai says that wind codes are deeply studied and adapted to realize wind tunnel tests and finite element analysis is performed for every component in detail. The products are certified by DNV and TUV. According to the company, the most important recent developments associated with the products are optimized integration of bifacial panels, torque tube section design and fatigue calculation of main components. The product has a tolerance for wind speeds up to 198 km/h and a 3-second gust. The tracker is also compatible with auto-cleaning robots (see Improvements At A Glance).
