NEXTracker has introduced its smart single-axis solar tracker family, ‘NX Gemini’, which enables two-module-in-portrait (2P) tracking of either monofacial or bifacial PV modules. The next-generation two-module-in-portrait (2P) tracker is optimized for customer sites with hard soils, challenging terrain, irregular parcel shapes, and high-wind requirements.

Solution

NX Gemini’s 2P architecture results in shorter overall row lengths for design flexibility and contiguous solar panels for maximum array density. NX Gemini allows for the maximum number of modules per foundation, requiring only 60 meters and seven foundation posts to provide support for up to 120 modules on four 1500-volt strings, which is claimed to deliver the industry’s lowest number of foundations per megawatt, according to the company. The ruggedized 2P tracker features a patent-pending self-locking, multi-actuator distributed drive system for maximum stability in all wind conditions eliminating the need for dampers and producing virtually zero energy losses associated with stowing.
