Unirac has launched the ISYS Single Axis Tracker at the Solar Power International (SPI) trade show, which is claimed to be the most robust and versatile ground mount tracker system on the market today. The system is able to work with any space or module system. Unirac backs the ISYS Tracker with a 20-year structural performance warranty.
EPCs, utilities and solar integrators have identified a distinct need for a higher-load capacity tracker requiring fewer foundation installations and offering quick assembly and reduced maintenance.
Designed for large-scale solar installations, the ISYS Single Access Tracker works with any standard solar modules, providing a flexible, highly versatile tracking solution for solar arrays. As with many of Unirac's other products, the ISYS Tracker allows for module pre-assembly. Optimized for quick construction, there is no field fabrication required and minimal foundation installations are needed. Unirac claims that 20 modules can be fitted on each foundation, four times that of competing solutions, which reduces construction time and materials are noticeably reduced, according to the company.
Commercial and utility-scale solar arrays
The ISYS Tracker is made with highly durable structural tubes that reduce material costs and enhance structural integrity. This combination of strength and design enables the ISYS Tracker to withstand up to 25 psf of snow and 120 mph winds while GPS and tilt sensors ensure a precise and unparalleled tracking system. It's also resistant to corrosive environments, further protecting its functionality and increasing return on investment for buyers. Standard bearings have been replaced by a no-maintenance, long-life sleeve/bushing to ensure parts performance over the long haul. The ISYS Tracker's simple, off-the-shelf hydraulic actuation system, featuring one hydraulic drive per 50kW.
