Power Plant

  • The power generation capacity of the plant is approximately 235 MWdc. Solar energy generation is dependent on natural conditions such as direction and height of the sun, cloud coverage and air temperature. Each year the plant will produce enough energy to power about 68,000(*) households.
  • This solar plant is located on about 260 hectares of the former 500-hectare salt field. That is the equivalent to about 56 Tokyo Domes.
  • It is expected to reduce approximately 125,000t(*) per year.
  • The solar panels used at the plant are "poly-crystalline silicon cell type". The technology is proven over several years and module structures and efficiencies improve on a daily basis.

Components of our power plant

Solar PV modules The solar PV modules convert sun light into electric power. It is a panel composed of a number of photovoltaic cells.
Combiner box This box bundles the DC power generated by the solar PV modules and supply to power conditioners.
Power conditioner The power conditioners convert the DC power supplied from the combiner box to AC power.
Transformer   Booster transformer
 
  Main transformer
 
Transformers increase the voltage of power produced from power conditioners to meet the requirement from the utility.
Weather measurement instruments Solar irradiance and other weather conditions are measured at the power plant.
Surveillance cameras The security cameras are used to check conditions of natural disasters and detect intrusions to the plant.
