The structure’s design principle is inspired by the beetle’s exoskeleton, which exhibits superior strength to weight ratio. The structure is a combination of an elliptical tube design and a simple lattice structure that holds the panels.
The elliptical tube, provides significantly superior stiffness and strength compared to the conventional frame designs of other tracker manufacturers.
The lattice structure, that supports the PV modules, is designed to lower the assembly time in the field, while providing high structural rigidity that protects the PV modules from forces that occur on the underframe under extreme external loads (wind, snow etc).
The zero-backlash hydraulic drive does not use gears or other means of mechanical transmission.
The purely hydraulic drive allows for smooth movement and operation. Also, due to the continuous slip capability under strong winds, the drive mechanism is extremely robust and capable of surviving even hurricane conditions.
REMOTE CONTROL AND MONITORING
The D30 is equipped with an advanced telemetry system which informs you of the machinery operations in real time.
The D30 uses an astronomical algorithm to find the position of the sun. This contributes to maximum solar radiation intake even when it’s cloudy and also helps the tracker to avoid unnecessary movements.
This results in an overall better tracking quality and up to 45% greater energy production, ensuring greater benefit per unit of installed capacity in comparison to fixed systems.
The installation of the D30 is quick and easy with the highest degree of standardization (plug & play).
All work takes place in the field without need of experts. The PV modules are easily fixed on the tracker by using the PV-CLAMP, which has been designed exclusively by Mechatron for that exact purpose.
