2. Other countries in Asia
 
India
India's national hydro power company plans to build the world's largest floating photovoltaic power station in the south of Kerala, with an installed capacity of 50MW. Calcutta's floating photovoltaic system for water testing was completed in January, 2015. The project includes 10 1 KW glass fiber photovoltaic modules, which can generate at least 1400 KWh per year, with an average of four KWh per day.
 
Korea
Topsun will develop a 100MW floating photovoltaic power generation system in Korea. The 100kW pilot project was scheduled to start in 2013, and the scale of the project has expanded to 100MW from 2014 to 2015.
 
Singapore
The floating photovoltaic power generation system installed on the water surface of garden’s pond in Singapore's Bi'An Park was successfully connected to the grid in 2013 with an installed capacity of 5KW. The system was invested by a private cooperative fund led by Phoenix Solar Energy Co., Ltd. It plans to test the suitability of the floating photovoltaic power generation system in the fresh water area for one year. Meanwhile, it will closely monitor the impact of the system on water quality, plants and animals, and quantitatively evaluate the expected benefits, like the improvement of photovoltaic cell efficiency by water cooling and the reduction of fresh water evaporation due to water cover. In addition, it can block the direct sunlight from the water body and prevent the propagation of algae.
 
3. Europe
 
Britain
As early as 2011, Phil Pauley, a British designer, proposed the floating solar cell, which is different from the current floating photovoltaic power station. It is a kind of mesh solar cell floating on the sea. The solar cells can be connected together to form a huge network structure. With the floating ship sinking and floating on the water, it can also collect the wave energy generated.
 
In 2014, the UK's first floating photovoltaic power station was built in Berkshire. The floating power station was located at Sheeplands farm near Wogref. It is composed of 800 photovoltaic panels with a total installed capacity of 200KW. The project costs 250,000 pounds. The investment will be profitable in six years. In the next 20 years, the farmer mark Bennett will receive a subsidy of 20500 pounds per year. The farm will save 24,000 a year on electricity.
 
Norway
In 2012, DNV researchers introduced the so-called dynamic floating offshore solar power plant concept. 4,200 560W thin-film solar panels can be a 2MW hexagonal solar array. If multiple arrays are connected together, a photovoltaic power station of at least 50MW can be formed.
 
The PV array is divided into several power generation areas, and each generating area transmits the generated power to two main switches collecting power, and then raises the voltage at a central transformer. The central island of the offshore solar farm is connected to a 30KV power transmission line, which connects a series of other solar islands to form a closed loop, and then continues to transmit power to the onshore substation for connection to the main grid.
 
4. Americas

U.S.A
As early as 2007, SPG Company of the United States built a 400KW floating solar array project in California. After four years of improvement, the company also launched a commercial floating solar array, which was installed in an irrigation pond in Sonoma County. The system was connected to the power grid through cables laid at the bottom of the pond. The project will be grid connected in 2016 with an installed capacity of 12.5MW.
 
Brazil
Brazil's pilot project of floating photovoltaic power station on water is planned to be carried out in barbina hydropower station in Amazon with a capacity of 350 MW, making it the largest floating solar power plant in the world.
 
5. Australia
This year, the construction of Australia's first floating photovoltaic power plant began. The project was located in a sewage treatment plant in Jamestown, South Australia, with an installed capacity of 4MW, spanning three water treatment tanks. The power generated will supply the sewage facilities themselves and enterprises in the region.
 
Conclusion
From the development of foreign countries, it can be seen that the development mode of floating photovoltaic power stations in various countries basically follow the mode of enterprise leading, government support and scientific and technological support. The scale of power stations has a growing trend from 1MW to several MW, and then to tens of hundreds of MW. At present, Japan maintains the maximum output record of floating power plants (about 13.4MW). However, South Korea, India and Brazil all claim that they will build the world's largest floating photovoltaic power station and it is now in the experimental stage.
