SunLink’s TechTrack Centralized* single-axis tracker pairs the most robust mechanical technology with best-of-breed project intelligence technology to deliver superior energy production and long-term ROI for commercial and utility-scale solar tracker projects anywhere in the world.

What Advantages Does Hydraulic Technology Provide?

With a unique power system based on the same globally accepted, proven hydraulic technology that drives heavy machinery in construction, power generation and beyond, the centralized TechTrack commands an industry-leading 1.2 MW per drive. This permits use of the highest quality drive components while achieving the lowest equipment cost of any proven solar tracking system on the market today.

Can TechTrack Centralized be Deployed Internationally?

SunLink’s design features internationally recognized industrial automation equipment, ensuring that components will always be available and eliminating the need to keep an inventory of spare tracker parts.

The hydraulic systems are built to withstand any environment, but should they require service, local technicians can be found worldwide.

Does SunLink Offer Turn-Key Services to Support TechTrack Centralized?
