The design of the Solar Ark was inspired by the vision of an ark embarking on a journey toward the 21st Century. Only four columns are used to support the entire structure, thus giving the impression of it floating in the air. Elevation of Solar Ark
| Construction | Steel frame with solid trusses. |

| Construction company | Kajima Corporation |
| Wind resistance/Earthquake resistance | Resistant to maximum wind speed of 34 m/s (peak gust of 60 m/s) |
| Resistant to level 7 on the Japanese earthquake scale | |
| Clear Coating Material | Fluorocarbon polymer coating (guaranteed rust-proof for 15 years) |
| Curvature | Upper radius: 2,001 m, Lower radius: 740 m |
| Construction materials | Designed to be ultra-thin, giving the Ark the impression of being suspended in the air. Structural steel was used that is 1.5 to 2 times the strength of normal steel. |
| Made using customized "G-Column" pillars produced by Kubota. These high-quality pillars are homogenous, due to a seamless construction method that utilizes centrifugal force. | |
| Max. diameter: 1,250 mm, Max. thickness: 120 mm, Pillar mass: Approx. 61 tons per pillar | |
| Base and shafts | 4 shafts of 2000 mm in diameter and 31 m in length are cast in each pillar and support pillars with a total of 16 shafts. |
| Base and shafts: (Base) Reinforced concrete 7.0 (W) x 7.0 (L) x 5.0 (D) m 4 pillars weighing a total of approx. 5,000 tons |
|
| Solar lab | Total floor area of this 2-floor, steel-structure building is 542.36 m2 |
| 9.3 (W) x 54 (L) m, Pillar span 9.3 x 36 m The Lab is built in a piloti style at a height of 4.5 m above the ground. The building is structurally separate from the Solar Ark. |
| Overview of Solar Cell Modules | Type: Single-crystal silicon solar cells |  |
| Dimensions: 1,320 (W) x 895 (H) x 35 (T) mm | ||
| Weight:15kg per cell | ||
| Number of solar battery panels installed:5,046 | ||
| Angle: 81 degree slant; 20 degrees west from due south | ||
| Solar Array Installation Type | 12 solar cell modules per unit (standard) were assembled on the ground, and 470 units were lifted up and attached to the main body of the Solar Ark. | |
| Total Power Generation of Solar Arrays | Groups of 6 solar cell modules are connected in parallel, with 841 circuits in total. | |
| Max. output: 630 kW, Estimated amount of annual power generation: 530,000 kWh | ||
| Power Conditioners | Rated output: 300 kW x 2 | |
