BACKTRACKING system with real time sensor (RTS) secures higher yields through
strengthening the tracker performance. Backtracking system maintain constant
efficiency through adjusting module positions when periods of low solar height,
lessening the effect of shadows on cells.
This system captures maximum and it shows better energy gain up to 30%.
SCATTERING MDOE was developed to increase energy harvest even on a
cloudy day. When sun is block by clouds, PARU trackers immediately operate this
mode to absorb scattering solar energy while RTS tracks the brightest source of
irradiation. This system perfectly matches with real time tracking method.
REAL TIME TRACKING SENSOR (RTS) is a technology developed to capture
maximum energy from the sun. It uses two solar sensors to detect the highest
point of irradiance, and instantaneously communicates with the tracker control
box to make the necessary movement to face the array perpendicular to the sun.
It simply means to accelerate ROI of your business.
SELF POWER CONTROLLER can be easily tailored to meet demands for OFF-
GRID market and extend the market along solar business value chain. The
high performance of independent power supplying device provides perfect
independent operations in less infrastructure places and natural environment.
ALLOY COATED STEEL is a high corrosion resistance product that is 5 to 10
times stronger resistance than that of a normal hot-dip galvanized steel sheet(GI,
GI(H)) with the same coating weight. It has an excellent cross section corrosion
resistance. With ALLOY COATED STEEL, PARU produces trackers.
ACTUATOR based on PARU core technologies deliveries stainable yields. This
critical part was developed by PARU and performs optimally throughout the
entire day producing more energy per hour than fixed type. Also the critical
parts operating with low voltage DC motors require low maintenance cost and
minimize downtime for service.

Simple assembly and rapid installation results in costs and efficient construction
schedules.
During the overcast sky, the PARU tracker absorbed all the diffused light by moving
the horizontal position.
Optimized power consumption vs. other AC power tracker.
The PARU Single Axis tracker offers fewer foundations per MW than the market
average. Direct impact on CAPEX.
Using the Magnesium Alloyed Metal (POSMAC) has resulted in the higher
corrosion resistance quality and long life. PARU tracker system protects itself in
high wind and faults conditions.
Automatically drives to slow position at high wind speeds. Mechanical protection
from over-travel. The simple and robust design requires minimum maintenance.
The Self-Power-Controller(SPC) enables to require no AC power source for drive
operating. It allows 10 days operation without recharging.
