OKEGAWA: 1,180 kWp

Located in Okegawa, in the prefecture of Saitama, Japan, this 1,180 kWp floating solar plant is installed on a rain water retention reservoir with an area of 30,000 m² (3 ha).

The platform is equipped with Classic version of Hydrelio® technology and supports 4,536 floating solar panels of 60 cells (260W JA SOLAR standard modules). The total structure covers 38% of the water surface.

For this project, Ciel & Terre supervised the engineering of the floating PV system. Our scope included:

  • Supply of our Hydrelio® (made in France) and design of the floating platform
  • Design of the anchoring solution

Anchored at the bottom of the pond, the anchoring solution has been designed to meet a maximum 0.6 m depth and a same water level variation (0.6 m, as the pond can be affected by drought).

 

Okegawa’s floating solar plant has been operational since July 2013, making this one the first megawatt-scale floatovoltaic project installed in the world, and generates green electricity to the local grid.
