Current Situation of Solar Power Generation

  • Fixed type
  • Automatic tracker type

Average efficiency of solar panel power generation is between 10 to 14%.
In addition, the total amount of an investment for the power generation plan is equired as its initial investment. Consequently, it takes about 8 to 10 years to be pay-backed. If we can utilize the photovoltaic generation loss (86 to 90%), this payback period can be reduced. But, still, the solar panel generation has problems almost impossible to be resolved, even by using today’s technologies.

Week Points

Solar panels installed mostly remain fixed. The panels set up on the east, receive mainly the morning sun, and those installed in the center receive rays of daytime and others on the west side receive sunlight in sunset. It is said the greatest weakness of the solar power generation is in unstable power generation, which depends on the weather (Sun).

That's why the sun tracking system was born, considering it is the best way to resolve that weakness. Our Sun tracking system follows the sun completely from the sunrise to the sunset and keeps always the solar panels faced directly perpendicular to the sun’s ray.

Our Sun Tracking System

Our heat-seeking solar tracking device (Sun tracking system) follows the sun completely from the sunrise to the sunset. It detects without any loss the heat of the sun’s ray and captures more efficiently the power generation.
The solar power generation efficiency of the panels installed on our San Tracking System with automatic solar heat tracking system recorded 38%, while the fixed panel’s one was 13%. (From: 100W solar panels comparison test in 2013)

Distinctive Features of our Sun Tracking System

  • 1) High efficiency omnidirectional continuous tracking technology with a high-sensibility heat sensor:180°(right-left) and 10 to 90° (up-down)
  • 2) Tracking error : less than ±1°
  • 3) Minimum illumination intensities : 3000lux
  • 4) Solar power stored in the battery is used as a power source of Sun Tracking System
  • 5) Minimization of power consumption (about 2w)
  • 6) Shorter payback period
  • 7) When the wind is strong (more than 15m/s), the solar panel moves to its automatic horizontal position, keeping a stall condition
  • 8) Safety Control by PLC communication system ( 1 control system for each power generation facility)

Main Specifications of Our Sun Tracking System

  • ① Easy anchor fixed method is used for its foundation work, as the frame structures for the panel installation are small and light.
  • ② Competitive price as it requires less foundation works
  • ③ Dual- axis high sensitivity automatic tracking in real-time by PLC communication system
  • ④ Remote and data controls are possible by PLC communication system
  • ⑤ Every panel-manufacturer's products can be used.
  • ⑥ With automatic panel turning function to horizontal position while the illuminance decays in the night
  • ⑦ In case of snow, the panel turns automatically and keeps its position as vertical as possible.
  • ⑧ It can be installed in sloping or uneven lands without soil preparation works
