The manufacturing of the Sun-Link Solar Tracker was done completely off-grid in an environmentally friendly way!
SUN-LINK Solar Tracker
The small PV sensor modules mounted on the east and west sides
of the array give extremely accurate information to the innovative
control circuit. The powerful actuator drives the array to the correct position
quickly and accurately. A 1000 watt array mounted on the Sun-Link will recover
all the energy used to drive the tracker through a full days operation in just 30
seconds of full sun.
∗ Comes complete with flanged steel mounting post, mounting bars specific
to your brand & size of module & stainless fasteners for modules.

SUN-LINK Solar Tracker Features:
- A powerful actuator which allows full function in windy areas.
- Is not affected by hot or cold weather.
- Has a robust circuit, rated 200% above maximum load, and is
epoxy potted to protect it from the environment.
- Does not put a parasitic load on your system. The power from
your system is only used to activate the actuator when the
circuit determines there is an advantage in moving the array.
- Works with any battery charging system from 12 to 48 volt.
- AC power supply allows the system to work without batteries.
Advantages over roof mounted PV arrays:
1) Lower cell temperature = higher output. Air flow around the array is
unrestricted. Avoids heat radiated from the roof itself.
2) Easy seasonal adjustment from the ground avoids the danger of climbing
and possible damage to the roof from ice.
3) More range of adjustment allows near vertical winter angle, almost eliminating
snow cover on the modules.
4) High noon performance from early morning.
Reliable and Inexpensive
The Sun-Link tracker delivers amazing performance. Typically the tracker’s first
movement is 20 to 30 minutes after sunrise on flat terrain. The circuitry is
designed to operate in steps, following the sun across the sky, making it more
efficient than continuous movement.
On bright cloudy days the PV array will take advantage of dispersed light by
facing south. On dark rainy days the tracker will not move when there is no
increased advantage in power output. This is a single axis tracker that uses
unique circuitry and photovoltaic technology to sense the direction of
maximum power output.
SUN-LINK Tracker Frames:
- Rated for 144 kph winds with 100 sq. ft. of solar modules.
- The frame adjusts for most popular PV modules.
- Has a simple manual seasonal adjustment that can be accomplished in minutes.
- Tracker frames are constructed of two part epoxy coated steel and are
assembled on site.
- New aluminum channel module bars
Advantages:
• Will position itself south on bright cloudy days, even if the sun is not visible.
• Doesn’t tend to follow the edge of the clouds.
• It will not move unless there is a significant increase in PV power output.
• It is immune to electrical disturbances in the DC system caused by charge
controls and inverters.
• Sun-Link is very efficient by moving in steps, waiting for the sun to pass and
following in its path. Typically plus or minus ten degrees.
Warranty:
The sun-Link tracker control - 5 years
The PV sensor modules - 10 years
The actuator arm - 2 years
