Installation effects

  • Power production
    • 1. Annual power production (total 317,865kWh) : (1st) 206,612 kWh, (2nd) 111,253 kWh
    • 2. Environmental effects
      Classification 1st 2st Total Unit
      Reduced oil consumption 44.39 23.9 68.28 TOE/year
      CO2 suppression effect 91.9 45.05 136.95 tCO2/year
      Reduced coal consumption 95,451 51,397 146,848 kg/year
    • 3. Production effects : utilized for the air-conditioning load of the building
  • Education and PR
    • 1. Contribution to energy demand and supply (replacement and savings)
      -The first project and the second project will combine to generate 317,865kWh per year and thus reduce electricity costs.
    • 2. The state-of-the-art and future-oriented facilities will be used for education and PR of energy saving and alternative energy.
    • 3. As one of the destinations of Daegu City Tour, it will be utilized as a tourism resource that will show the image of a cutting-edge city to Daegu citizens, domestic and foreign visitors.
    • 4. It is easy to attract international academic conferences related to energy and solar city.
