Antaisolar, a well-known Chinese solar tracking system and fixed tilt racking solutions provider established in 2006, exhibited its latest 1P TAI SIMPLE series tracking system and roof mounting systems at the Intersolar 2024 event in Munich, Germany. The company has 6 production facilities, 4 of which are in mainland China and 2 overseas- 1 in Turkey and 1 in Indonesia.
Speaking to TaiyangNews during the exhibition, Antaisolar highlighted the 1P TAI SIMPLE series tracker and fixed rooftop racking systems.
1P TAI SIMPLE tracker
Drive mechanism
The TAI SIMPLE series tracker displayed at the event is a multiple slew-drive single-axis independent 1P tracking system. That means each tracker has more than 1 slew-drive mechanism, which can independently and accurately rotate the PV modules connected in a 1P portrait configuration in sync with the Sun’s movement from east to west, noted the company.
The tracker’s multiple slew-drive rotating mechanism offers advantages in terms of increased PV module load-carrying capacity, enhanced tracking precision, and flexibility in undulated terrain. According to TAI SIMPLE’s technical specifications, the tracker can accommodate up to 3 strings of 1,500 V system voltage in a 1P configuration. Its wide east-to-west rotational range of +/- 60° ensures higher power generation over different types of terrain, added Antaisolar.
Structure
In addition to a flexible driving mechanism, the company says the tracker’s structure also offers high reliability and versatility. Antai offers structures made of different grade steel materials depending on customer demand—pre-galvanized, hot-dipped galvanized, and magnesium-zinc-coated—which enhances the structure’s reliability in long-term exposure to external stresses. Its structures are designed for easy installation over a wide range of foundations, such as concrete or pile ramming steel. The company says the TAI SIMPLE series tracker is certified to experience extreme wind loads of up to 55 m/s, as per ASCE 7-10 standards.
Control
The tracker maker highlighted its upgraded mono control unit (MCU), which enhances system uptime by operating on connected PV string power sources. The latest control unit, with its advanced algorithm, improves tracking accuracy up to +/- 2°. Antaisolar noted its wireless communication under Zigbee wireless protocol helps save on control wire costs during installation.
Roof racking system
Alongside the 1P tracker, Antaisolar displayed multiple PV module mounting systems for different roof applications.
Metal roof solutions
The company showcased racking systems under the MetaRoof brand—for clamps with rails and mono-rail application. Its clamps with rail-type racking systems are available in 2 models—L-feet with C-Rail and Trapezoid L-feet with C-Rail. The L-feet mounting system over the C-rail features good flexibility to match various types of roof clamps. On the other hand, the Trapezoid L-feet model’s non-penetrating roof clamp mounting ensures watertightness of the roof structure, according to the datasheet.
