Investment Cost Effectiveness
Although the cost of POLO Solar Tracker is slightly higher when compared to an equal capacity fixed installation, the increase in energy production is significantly higher than the increase in the investment capital, therefore the IRR and the NPV of the investment is greatly improved.
The POLO Solar Tracker’s lean design is based on Mechatron’s accumulated design knowledge and field experience. Every detail has been thoroughly engineered to have the minimum impact to LCOE.
The motion mechanism can drive up to 8 rows, 53 m long and 3 m wide each (25 kW). The position of the pivot joints and the motion mechanism is out of reach of the modules during the operation, therefore there are no gaps above the foundation, making POLO Solar Tracker the solution with the best Ground Coverage Ratio.
The structure is a combination of large diameter rectangle tubes and cantilever purlins providing maximum material usage efficiency and enabling great cost reductions.
In order to secure safe operation for many years the POLO Solar Tracker uses a hydraulic motion mechanism. The motion mechanism is completely assembled and tested prior to shipping and it is delivered ready to be installed and switched on (plug and play).
Time and Cost Savings In the Field
The installation of a POLO Solar Tracker is quick and easy with optimized functionality in every step of the procedure. The high stiffness and stability design enables the foundations to be 5 m apart, reducing labor and material costs during assembling (compared to the costly narrow spaced foundations of fixed installations).
Also, the use of the M-CLAMP clamp saves labor time, as each module needs less than a minute to be mounted on the tracker.
There is no need for field work (drilling, cutting, welding, etc) and there is no room for decisions during assembling, thus eliminating application errors and the need for expert staff.
The POLO Solar Tracker foundation and assembling cost is kept similar to, or in many cases even lower than that of fixed mounting systems.
The networked Tracker
Mechatron Solar Trackers are equipped with the most advanced telemetry system. Each plant has a web control interface with an incorporated web server which connects the plant with World Wide Web though any available connection type (aDSL, GSM, etc). This web control interface is communicating with each tracker of the plant and monitors their status.
Plant operators can log-in from any browser and see the status of each tracker. They are also able to interact with any tracker and make movements or perfotm any test they wish.
In case of failure the telemetry sends a message to the operators which contains a description of the probable cause of the fault. Messages can be sent by SMS or E-mail.
