Dual Axis Control Mode


  • Automatic Safety Mode

       When sun brightness is below 3,000 lux (continuously for longer than 2 hours), the tracker goes into a Safety, Horizontal, mode automatically.


  • Maximum Generation Efficiency

       Real time tracking (Azimuth / Altitude) → Tracking the optimal irradiance angle


  • Snow Mode

       Altitude Angle will be changed by heavy snow (It is possible to adjust the angle(0º~45º) manually)

Are you familiar with the Battle of the Alamo?


As one of the most famous battles, the Battle of the Alamo was a pivotal event in San Antonio, Texas, USA. Following a 13-day siege, Mexican troops under President General Antonio López de Santa Anna launched an assault on the Alamo Mission near San Antonio de Béxar (modern-day San Antonio, Texas, United States), killing all of the Texian defenders. The Alamo was the key to the defense of Texas, and they were ready to give their lives rather than surrender their position to General Santa Anna. People worldwide continue to remember the Alamo as a heroic struggle against impossible odds — a place where men made the ultimate sacrifice for freedom. For this reason, the Alamo remains hallowed ground and the Shrine of Texas Liberty.

180 years later, 2014, a Korean leading solar PV company, PARU started one of the world’s largest solar projects with 400MW solar Tracking System (approximately $150 Million) here in this historical area. The land size of the project is 4 times bigger than Yeouido and also 1,700 times bigger than a soccer field. 400MW is enough electricity to run 400,000 households daily. PARU’s technology has been acknowledged and accepted not only domestically but also internationally. PARU’s Alamo project will be continued until 2016.

With various Tracking Methods


Receives signals from sensors as solar/wind sensors, etc. and transfers those signals to “Slew Drive”, “Actuator” to control the tracker according to user’s configuration. The type of controller shall be variable to customers’ local conditions. Only 1 controller shall be offered per tracker.


- LCD Display 

- Auto/Manual control 

- Safety Mode 

- Real-time tracking control 

Real-time Sensor

A component that senses the location of the Sun and sends signals


- E/W Sensor, sensing Sun’s East and West

- S/N Sensor, sensing Sun’s North and South

Linear Actuator

To control the vertical (elevation) angle of the tracker. Stokes of the Actuator can be changeable according to the tracking angles.


- High Degree corrosion protection

- Vibration resistant 

- Duty cycle up to 100% 

Slew Drive

To control the horizontal (azimuth) angle of trackers.


- High torque transmission 

- Reduced backlash 

- Max. Load capacity and extended life
