Upon completion, the first phase will annually generate about 2.4 million kilowatt-hours of electricity.
Frances Ciel et Terre has confirmed that it will supply its Hydrelio floating platforms for the project, which will span an area of 240 metres by 200 metres on the surface of the Akungtien reservoir, north of the southern city of Kaohsiung.
Cottbus-based PV solutions specialist GermanSolar, which has a regional office in the Taiwanese city of Hsinchu, has not revealed when it expects to complete the second phase of the project.
Lille-based Ciel et Terre which has offices in Tokyo and Shanghai has already cornered the small market in Japan for floating PV installations with its Hydrelio platforms.
The floaters are made of recyclable, high-density polyethylene and are guaranteed to withstand typhoon conditions over periods of 30 years.
Earlier this year, Ciel et Terre started working on a 13.7MW floating PV project at a dam near Tokyo with Japanese PV module supplier Kyocera and its partner, Century Tokyo Leasing (CTL).
And in June, Ciel et Terre revealed that it had started working on a 10MW floating demonstration project in eastern Brazil, in cooperation with Brasília-based utility Eletrobras.
