Float-Type Photovoltaic Power Generation System for Water Purification of Honen Pond, Kagawa Prefecture

Kagawa Prefectural Government
Kawasaki Steel Corp.

This is a 30 kW photovoltaic power generation system introduced as a power source for a water purification system of an irrigation water reservoir. A float-type system (a system with solar cells floated directly on the water surface) is employed to fit the surrounding scenery. It is expected that the system will be widely used for purifying water of lakes and ponds.


Features of Equipment, System and Facilities

Each module, having a float integrated, can be installed independently, to enhance the degree of freedom in installation scale, and to allow applications to various sites.
Compared with the conventional water surface installation method, no pontoon is required, allowing cost reduction.
Since the solar cell module is installed on the water surface, the water can cool the module, preventing a lowering of conversion efficiency due to a temperature rise. Thus, the power generation efficiency has improved relatively.
