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.
Problem
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.
Solution
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.
Applications
Commercial and utility-scale solar arrays
Platform
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 Standard bearings have been replaced by a no-maintenance, long-life sleeve/bushing to ensure parts performance over the long haul.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.
Availability
October 2011 onwards.
Latest Comments
Wonder what the warranty on the drives might be. Sure, steel will certainly last 20 years.
One hydraulic drive per 50KW as opposed to 1 motor per 300-400KW for ATI Tracker and 400KW for T0.
This post omits the important detail of the relative size of these foundations compared to the competition. RayTracker tried the “fewer/deeper” foundation approach and ended up with costly 8” 20’ tube steel members. Hydraulics close to dirt surface doesn’t engender confidence. This blog should seek to provide objective perspective, not sales language, for its readers.
