SOLAR ARK

Construction Material 01
  • Designed to express the floating image of an ark. Constructed of high-strength construction steel 1.5 to 2 times stronger than regular steel.
  • "G Column" A custom-designed column by KUBOTA, which is a high quality seamless circular column produced by centrifugal casting method, was used.
    Maximum diameter: 1,250mm
    Maximum wall thickness: 120mm
    Weight: approx. 61 metric tons per column was used.
    Maximum diameter: 1,250mm
    Maximum wall thickness: 120mm
    Weight: approx. 61 metric tons per column
Foundation and Piles 02
  • Pile: 2,000mm in diameter and 31m long
    4 piles are used to support a column thus 16 piles support the columns.
  • Foundation: Reinforced concrete
    Size: W7.0m x L7.0m x D4.5m
    Foundations were laid in 4 places under each column
    Built to support up to approx. 5,000 metric tons
Lab Space 03
  • 2 story steel-frame construction with floor area of 542.36m²
    Floor space: 9.3m x 54m
    Distance between columns: 9.3m and 36m
    Self-sustaining elevated-floor style construction with the distance from the ground being 4.5m
    Building is constructed independently from the ark structure

Main Structure of Solar Ark

Solar cell module descriptions
  • Type: Single crystal silicon solar cell
  • Size: W1,320mm x H895mm x T35mm
  • Weight: 15kg/module
  • Total number of modules used: 5,046
  • Tilt angle: 81° to the ground Direction: 20° west of due south
Installation system of solar module array
  • Standard units of 12 solar cell modules were assembled on the ground and raised.470 units were installed on the body of the ark.
Power generation capacity of solar cell array
  • 6 solar cell modules are connected in a series and 841 circuits are configured in parallel.
  • Maximum Output: 630kW
    Estimated Annual Power Generation: 530,000 kWh
Power Conditioner
  • Rated Power: 300kW x 2 units
  • Input Voltage: DC270V Output Voltage: AC440V
Application and Interconnection
  • DC power generated in solar cells is converted to AC
    power and once the voltage is increased to 6,600V, it is then connected to the in-plant substation.
  • Generated power is used in the plant, and there is no reverse power flow.
