Maintenance Free Horizontal Single Axis Tracker
Working principle:
The solar sun tracker is a kind of power unit that can maintain the
solar cell board facing the sun, so the sunlight can vertically ray
on the board that can obviously raise the module's electricity
generation efficiency. Solar tracker controller is a system that
tests and optimizes the tracking accuracy of single-axis solar
trackers. It accurately monitors second by second the inclination
of PV modules, analytically calculates the deviation from the
optimal tilt, and generates the tilt-correction parameters
delivering optimized alignment and maximized energy production.
In traditional fixed type plants, the power output follows a bell
curve during the day, it gradually increases until peaking at noon,
then begin to decrease. However, in single axis solar tracker
plant, we get the maximum power from early morning and this output
is maintained until late afternoon. Hence, the performance will be
increased of approximately 25% as compared to the fixed PV
installation.
Our solar sun tracker choose the slew drive, enabling each row to
be independently controlled by its own motor with the tracking
method ‘Astronomical algorithm + closed-loop control’. making the
system accurate and reliable, real-time closed-loop feedback
tracking angle, automatic tracking, without human intervention.
Functions:
1. High reliability: It can handle freely in the area with serious
electromagnetic interference. Its excellent electromagnetic
compatibility design ensures high reliability operation of the
system.
2. Intelligent wind resistance: It is automatically leveled to the
initial position at night. At the same time, the system has a wind
load protection interface and supports an external wind speed
sensor, which can control the system to enter the maximum wind
resistance state of the machine at any time.
3. Power-off memory: There is a backup battery inside the system,
which can ensure that the system power-off data is not lost, and
automatically enters the running state after power-on.
4. Remote Communication, Group Control for Multi-Equipment
Automatically identify the failure, with automatic self-protection
and alarm; Quadruple over-current protection ensures the safety of
the whole system
