600 m², Autonomous Horizontal Single Axis Tracker
Less than 10% increase in CAPEX
up to 25% more energy production
ENGINEERED TO LAST
The S5 uses a hydraulic drive which despite its higher initial cost compared to electric drives, 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.

DISTRIBUTED MECHANICAL LOADING
Depending on its length the tracker can have up to 6 actuators, where each actuator drives a 1/6 sector of the total length. This means that the maximum free rotating length on each side of the actuator is less than 12,5m. This very short free rotating length (unlike most other available solutions) gives exceptional torsional stability and zero backslash in alternating eccentric loads which usually occur during extreme wind conditions. This high torsional stability eliminates the need for stabilizers or shock absorbers.
All moving joints are made from a combination of stainless steel and bronze components and they do not require any kind of maintenance throughout the service life of the machine.
A change of the hydraulic oil and filter is required every 5 years.
All drive and control components can be removed and replaced in a few minutes, without disrupting the operation of the rest of the plant and without the need to dismantle the table.
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 innovative Six-Axis Hinge can absorb up to 10cm of foundation pole misplacement in any direction, it also makes possible the installation on areas with extreme slopes. S5 can be installed on slopes of up to 15° in the North-South direction, and on unlimited slope in the East-West direction.
The tables are independent from one another and can have different lengths, thus making very easy the distribution of trackers in irregular fields. The lack of power and communication cabling, reduces the installations costs and time. The S5 foundation and assembling costs are kept similar to, or in many cases even lower to that of a fixed PV system installation.
Since the Six-Axis Hinge and the rotation mechanism does not interfere with the PV modules during operation, there are no gaps between the PV modules, making the S5 the solution with the best ground coverage ratio in the market.
The S5 is equipped with an advanced control system. A single Master
Controller can communicate and control wirelessly up to 256 S5 trackers. The Master Controller, incorporates an anemometer and a GPS receiver. By using the time and position information from the GPS, the Master Controller solves the astronomical algorithm to find the sun’s position. Then the Master Controller applies the backtracking rules and if the wind speed or the snow is inside the safe limits, it broadcast the optimum position to each table.
The Master Controller connects the plant to the Internet through WiFi or Ethernet TCP/IP connection. The owner or the plant operator can have access to the plant through any web browser. There are several user access levels available to suit any security needs (viewer, operator, superuser). The users are able to interact with the trackers and make movements or perform any test they wish.
If an error occurs, the Master Controller can inform the operators by sending a message which contains a description and the probable cause of the error. Messages can be sent via SMS or E-mail.
During the first or the last hours of the day, where the sun is close to the horizon, the Master Controller continuously adjusts the slope of the modules as to prevent the Tables from casting shadows to each other.
