Single Axis Tracker Introduction
Solar First single axis trackers have one
degree of freedom
that acts as an
axis of rotation
. The axis of rotation of single axis trackers is typically aligned along a true North meridian. It is possible to align them in any cardinal direction with advanced tracking algorithms.The orientation of the module with respect to the tracker axis is important when modeling performance.
Applicable Areas
1. Mid-high latitude flat land, mountainous terrain
2. Suitable for all types of modules, C-SI, A-SI, bi-facial modules
Features & Advantages
1. Higher installation capacity, single array up to 400KWp Max.
2. Higher terrain flexibility, adaptive slope N-S direction 5°,E-W 12°
3. Higher reliability control& drive system, Siemens PLC control and verified components ensure the reliability of controller, one-click operating design, fewer number of control and drive units, fewer piles, allow for simple installation,operation and maintenance.
4. Full automatic tracking, high tracking accuracy of less than 0.5°,additional electric power output by 15-25%
5.Centralized control,convenient for overall arrangement for power/communication wires
6.Wireless monitoring system & closed loop control system,maximize tracking accuracy and system reliability

FAQs:
Q1:
What are the types of single axis trackers Solar First makes?
A: The types of Solar First single axis trackers includes horizontal single axis tracker (HSAT), horizontal single axis tracker with tilted modules(HTSAT), vertical single axis tracker (VSAT),tilted single axis tracker (TSAT). The orientation of the module with respect to the tracker axis is important when modeling performance.
Q2:
What is the capacity range of your single axis tracker?
A: One single array of SF horizontal single axis tracker(HSAT) is up to 400KW max , depending on terrain conditions.
Q3:
Is your system centralized or decentralized?
A: SF provides both centralized and decentralized systems. And we offer customized solutions on a project basis.
Q4:
Solar panels are included in your single axis trackers?
A: No. Unless otherwise prior required.
Q5:
Do you offer a complete single axis tracking system for grid or non-grid purpose?
A: Yes. SF offers a complete set of solar power system including panels, inverter, controller, cable and battery package (for non-grid system) .
Q6:
What is the product warranty?
A: 2 years on the mechanical and electrical, 10 years for steel structures.
Q7:
What technical supports will you offer?
A: SF will offer full on-line technical supports in terms of installation,debugging and operation. On-site support is available with the scaled projects.
