Technology of Dual-Axis Tracking System
PARU’s technology is acknowledged not only domestically but also globally. Based on an optimal design process. PARU develops excellent quality products and reduces risks through analyzing cases from FRACA and FEMA. PARU also runs continuous test beds to prove product reliability and operates CFD and FEA simulation to develop a safer system. 13 different patents and international certifications, including UL, prove PARU’s global competitiveness.
Product Specification
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.

▲ PARU's Dual-Axis Tracker (USA Alamo)
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
Controller
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

PARU
Single Axis Tracker produces optimal efficiency of the solar PV. Compared to the Fixed type, this has up to 30% more of a generating efficiency.
Fixed type was established through the process including simplifying structure, convenience of constructing and installing, and minimizing welded areas.
Utilizing the fixed type’s structure simplification, construction, and easy installation, PARU developed a carport type solar product with a sense of taste and uniqueness.
