Kyocera Begins Construction On World’s Largest Floating Solar Power Plant

January 25th, 2016 by  

Japanese multinational manufacturer Kyocera has announced it has begun construction on the world’s largest floating solar PV power plant.

The competition for largest floating solar PV plant has been heating up over the last few years, with one company after another all vying for contention. Kyocera is generally held to be the company leading the way: In November, 2014, the company announced that it would be developing a 7.5 MW solar power plant atop the Umenokifurukori reservoir in Japan, which was followed a month later by an announcement for a 13.4 MW floating solar power plant atop the Yamakura Dam reservoir in Chiba Prefecture, Japan.

Kyocera-2Announced last week, Kyocera revealed that it had begun construction on the Yamakura Dam project, with the 13.7 MW project expected to be completed for launch in the fiscal year ending March 31, 2018.

In cooperation with co-shareholders, Tokyo Leasing Corporation, Kyocera has begun construction on the project on the Yamakura Dam reservoir, managed by the Public Enterprises Agency of Chiba Prefecture in Japan for industrial water services.

The completed project will comprise of approximately 51,000 Kyocera solar modules installed over the freshwater surface of the Yamakura Dam, across an area of approximately 180,000 square meters. Upon completion, the project will generate an estimated 16,170 MWh of electricity per year, which is enough to power approximately 4,970 typical local households, and offset 8,170 tonnes of CO2 emissions annually.

Floating solar is especially important in Japan, with the increasing lack of available tracts of suitable land required to develop conventional land-based solar PV installations a non-issue when floating solar can be installed on Japan’s abundant freshwater resources.

    If all the hydro power plant’s 40% catchment area is covered with floating solar panels, then some load on land is reduced and life in the water will be less harmed as they have some area for growth. Evaporation will be curtailed and summer days will be liveable for flora and fauna.

    Hey Joshua, by my math that means the plant would be running the equivelant of something like 50 days a year. Is this more due to the nature of solar power (i.e. needing sunlight) or the plant itself?

      In Chiba Japan, which is where this dam is, along with Tokyo Disneyland, optimally aligned fixed panel will receive the equivalent of an average of 4.2 hours of direct sunshine a day. This means they could operate at a capacity factor of up to 17.5%, although in reality I’d expect to operate at around 16% or more, if fixed, which I guess it is since it would be hard to rotate something that big without smacking it into land. But it appears these panels will only operate at a 13.5% capacity factor. There could be several reasons for this. Maybe the dam doesn’t get as much sunshine as I think, or perhaps the facility will be inverter limited, or maybe they are just lowballing the expected generation amount.
