Detailed Specifications of Solar Ark
Main Structure of Solar Ark
- Structure: Three dimensional steel truss structure
- Construction area: 3294.48m²
- Area of the South Side elevation : Approx. 7,500m²
- Overall length: 315m
- Height: 31.6m (center) - 37.1m (both ends)
- Width: 4.3m (top) - 13.7m (bottom)
- Distance between the ground and the building base at both ends: 20m
- Distance between columns: 126.6m lengthwise and 13.7m breadthwise
Cantilever: 94.2m from column to end
- Weight: 3,000 metric tons
Wind and Earthquake Resistance
- Resistant to 34m/s wind speed and 60m/s gusts
- Resistant to level 7 on the Japanese earthquake scale
Would be able to withstand an earthquake the level of the Great Kanto Earthquake of 1923 and Great Hanshin Earthquake of 1995.
Curvature
- Top curvature radius: 2,001m
- Bottom curvature radius: 740m
Surface Painting Material
- Fluoropolymer painting (guaranteed rustproof for 15 years)
Construction Material 
- 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 
- 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 
- 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.
