Technical characteristics
Structure typeThe STT1 is designed as a single row system, i.e., the built-in motor is directly related to a single axis.
AngleThe trackers rotate East-West throughout the day, with a +/- 55º tracking range
SlopeMaximum north-south slope is 12%, however, the east-west slope is unlimited. It also possible to adapt to other conditions.
Structure materialsAll the trackers use the following materials: HDG Steel S280, S355, S350GD ZM310 (Magnelis). The bearings however are made of polymeric, self-lubricating materials (requiring no maintenance.)
Assembly All the tracker joints are bolted, using GV class 10.9 bolts.
Set-upThe set-ups we have are 1V, 2V and 3H.
StandardsThe wind codes/standards that have to be met are: Spanish Building Code (CTE), Eurocode, ASCE07, local standards
Temperature rangeThe tracker tolerates temperatures from -20ºC to +55ºC.
Module fasteningDepending on the tracker configuration, the modules are fastened by means of staples or screwed assemblies.
FoundationDepending on terrain characteristics, the foundation can be direct pile driving, pre-drilled, foundation bolts or footings.
Wireless communicationCommunication between the various control system elements is via Zigbee protocol. This is a wireless protocol, eliminating the need for communication cables between elements separated by large distance and reducing the likelihood of failure.
Remote or on-site dataThe system includes an internet connection and an industrial PC where it is possible to view data. Data can also be viewed remotely, with an option to include a data viewing environment to make it easier for the customer to understand the data.
Up to 200 solar trackers per control unitEach central control unit can control up to 200 individual tracker units, making it possible to produce large projects without needing additional central control units, helping to acquire data in a far more centralised way.
