ENGINEERED TO LAST
The S250’s design is based on our accumulated design knowledge and extensive field experience. Every detail has been thoroughly engineered to have the minimum impact to the levelized cost of electricity (LCOE).
The S250’s design presents high rotational stiffness while keeping the natural frequency close to 2 Hz. It also has exceptional stability in alternating eccentric loads which usually occur during extreme wind conditions.
The high stiffness and stability of the main carrier tube allows the foundations to be 6 m apart, reducing labor and material costs during assembling (compared to the costly narrow spaced foundations). The Drive Mechanism can actuate up to 12 (42 m long, 3 m wide ~20 kWp) Tables, thus enabling almost 250 KWp of PV modules to be installed per single tracker.
The S250 uses hydraulic axis drive, which despite its higher cost compared to other technologies, is the only safe choice for harsh environments (proven for decades in earth-moving machinery). The hydraulic circuit is isolated from the environment and the hydraulic oil is constantly filtered by a micro-filter. This makes the operation possible even in the thin dust of a desert, securing reliable and low maintenance operation for many years.
The innovative Six-Axis Hinge can absorb up to 10 cm of pole misplacement in any direction, it also makes possible the installation on areas with extreme slopes. Slopes up to 17 degrees can easily compensated in the North-South axis, and unlimited slope in the East-West.
Since the Six-Axis Hinge does not interfere with the PV modules during operation, there are no gaps between the PV modules, making the S250 the solution with the best ground coverage ratio in the market.
We have optimized every step of the procedure. There is no need for field work (drilling, cutting, welding, etc.) and no need for decisions during assembling, thus eliminating installation errors and the need for expert staff.
The S250 foundation and assembling costs are kept similar to, or in many cases even lower than that of a fixed PV system installation.
The PV-CLAMP saves labor time, as each module needs less than a minute to be clamped on the tracker. Visit the following link to learn more about the PV-CLAMP: www.mechatron.eu/3z7q
The S250 uses an open loop astronomical algorithm. By using direct GPS information, the Plant Controller CPU solves the astronomical algorithm to find the sun’s position and drives the PV module surface to the most appropriate position against the sun.
During the first or the last hours of the day, where the sun is close to the horizon, the Plant Controller continuously adjusts the slope of the modules as to prevent the Tables from casting shadows to each other.
WEB ADMINISTRATION AND OPERATION
The Plant Controller incorporates a web server, which allows the plant to be accessed through the internet.
The Plant Controller controls and communicates with each tracker while showing the status of the plant a well designed web interface.
Plant operators can log-in from any web browser to see the status of the plant. They are also able to interact with the trackers and make movements or perform any test they wish.
In case that an error occurs, the Plant Controller can inform the operators by sending a message which contains a description and the probable cause of the fault. Messages can be sent via SMS or E-mail.
