Mr de la Viña’s presentation included an overview of how Vanguard 1P is integrated within the rest of the tracking solutions that TrinaTracker offers to its clients.
“Vanguard 1P series, fully compatible with ultra-high power modules ranging from 400W to 670W+, further enriches the tracker's application scenarios and upgrades TrinaTracker solutions” said Mr de la Viña.
Oscar Aira, Head of Solutions Sales, EMEA, explained the mechanical characteristics incorporated in the state-of-the-art tracker design. He described how ‘Trina Clamp’, reduces installation time by up to 70 percent. The also patented ‘TrinaTracker Spherical Bearing’ improves terrain adaptability, ramming ratio and eliminates risks of misalignment and additional forces that create extra friction.
Mr Aira introduced the various differentiating innovations that Vanguard 1P includes. The tracker has a new 130 x 130 mm torque tube with round edges that increases bending resistance by up to 12 percent and the torsional one by almost a 30 percent. The torque tube also allows more distance between piles, reducing the number of the structure's components and consequently leading to an appreciable impact in the installation's cost.
The tracker also includes a dual-damper system that reduces the time of tracker oscillation, prevents the oscillation spread, improves the dynamic response, and increases the critical wind speed.
Oscar Aira also explained how TrinaTracker integrates intelligent solutions ‘SuperTrack’ and ‘Trina Smart Cloud’, adding value to Vanguard 1P. He presented Supertrack as a smart tracking control system that combines Smart Tracking Algorithm and Smart Backtracking Algorithm to increase energy generation by up to 3-8 percent. In addition, ‘Trina Smart Cloud’ a unique intelligent monitoring control solution, enables reliable and accurate operation across a wide range of weather conditions and increases productivity from preventive diagnosis and O&M suggestions.
Juan Manuel Gómez, Head of Support Structures Research and Development (R&D), talked about TrinaTracker R&D capabilities and explained the process of development and testing implemented in Vanguard 1P. Juan Manuel Gómez, also presented an introduction of the wind tunnel performed on Vanguard 1P by CPP, which was later supported by Dr Jubayer Chowdhury, Senior Engineer at CPP, who illustrated the pressure and the full aeroelastic tests implemented in the tracker.
Dr Jubayer Chowdhury emphasised the importance of performing a full 3D aeroelastic wind tunnel test to obtain critical wind speed for torsional instability, as was done by CPP for Trina Trackers.
“Such wind tunnel tests with 3D aeroelastic models of trackers ensures tracker safety by providing two key information, one, the wind speed at which the tracker should be in stow, and two, the maximum wind speed trackers can withstand during a windstorm” Mr Chowdhury said.
The webinar showed how Vanguard 1P widens the portfolio de tracking solutions that TrinaTracker offers to its clients.
