The tracker claim
ARRAY has launched a DuraTrack D2S dual-row tracker with a patented passive wind-stow approach and a stated 60-degree stow angle. The company says the system is designed for temperatures from -20 C to 60 C, with an option to -40 C. Source: Solar Power World.
Why wind stow belongs in the RFQ
Stow strategy affects more than controls: it influences torque-tube loading, driveline selection, foundation reactions, row spacing and operational procedures. A tracker comparison should therefore use the same wind basis, terrain assumptions and module configuration for every bidder.
Land use and operating envelope need validation
ARRAY also says the configuration can fit up to 6.3% more installed capacity on the same land area than designs with bearing-housing gaps. That type of claim is a useful design input, but developers should validate it against actual setbacks, topography, drainage and maintenance access.
Buyer impact
For a single-axis tracker review, buyers should ask for the design wind basis, stow logic, temperature range, pile loads and layout assumptions in writing. This makes technical comparisons more meaningful before a preferred supplier is selected.
