my country's first floating photovoltaic power station was completed in Yunnan. Compared with Japan, Britain, South Korea and other countries, it has successively settled in floating photovoltaic power stations. my country has started late. At present, Japan has maintained the largest output record of floating power fields. However, with the development of the industry and the advancement of technology, it is believed that more and more domestic companies will start to get involved in the development and utilization of floating photovoltaic power generation systems.
1.7 MW and 1.2 MW large water photovoltaic power station in Hyogo Prefecture, Japan, jointly invested by the Kyochrome Co., Ltd. and Tokyo Shengshi Lease Co., Ltd. were put into operation at the end of March 2015; Dreamsolarfloat1, a photovoltaic power station with a power of about 1.044 MW, started construction on April 14th and started to sell electricity at Kansai Electric Power Company in October this year. Previously, Britain and the United States also had a precedent for floating solar power stations. And domestic information has not been obtained about floating photovoltaic power stations.(Lithium - Ion Battery Equipment)
Beijing Porcelain Large Water Philosophy Power Station advantage
1. The floating shelf platform is a hollow structure, which facilitates the passing of the wires to reduce the infrastructure and land costs brought by the cable groove in the ground photovoltaic power station;
2. Floating photovoltaic power stations are integrated, which is convenient for the installation and operation of the solar tracking system.
3. The photovoltaic panel is based on the floating surface of the floating surface. Due to the cooling effect of the water, the photovoltaic power plant can get more power generation than large ground power stations and roof distributed photovoltaic power stations;
4. Floating photovoltaic power stations can cover a large amount of water body and reduce the evaporation of the reservoir water. At the same time, due to the obstruction of the sun, it forms a large projection surface. To a certain extent It will affect the breeding industry;
5. 100%recycling can be recycled. High -density polyethylene is used to resist ultraviolet rays and corrosion;
6. The surface power plant is attached to the water body. When the typhoon comes, it can float with the water body to prevent damage and resist the attack of the typhoon;
7. Floating photovoltaic power stations on the water surface rely on the surface of the water body to reduce the occupation of land, forest land, grassland and other land;
8. It can be assembled through the shore, convenient transportation and installation;
9. The surface photovoltaic power plant is in the water environment, eliminating solid adsorption such as dust, and realizing the true free cleaning, reducing the cost and power loss caused by the cleaning of the photovoltaic panel.
Program cost of floating photovoltaic power stations
Taking the shore -and -field storage pool on the shore -on -pivot power plant as an example, the area of the storage pool is about 20,000 square meters, and 4016 Taiyangneng battery boards will be laid on 10,000 square meters of them with a power generation scale of 1.044 MW and a investment amount of about 500 million days. The yuan, which was equivalent to approximately RMB 25.8 billion, and a uniform kilowatt cost of 24,700 yuan, compared with the current uniform level of 8,000 yuan in the kilowatt cost of the current ground photovoltaic power station in my country. However, because my country's land and resources are largely different from the price and labor costs of Japan, it is for reference only.
The domestic cost unit price of high -density polyethylene is 6,500 yuan/ton, and the domestic cost unit price of plating ZN steel brackets used in ground photovoltaic power stations is 3400 yuan/ton. 0.965*103 kg/cubic meters, the density of steel is 7.85*103 kg/cubic meter, about 8 times the density of high -density polyethylene, so if you only consider the volume factors, the weight of polyethylene is 1/ 8. Considering the unit price, the total cost of using polyethylene as the floating shelf is about 1/4 of the cost of steel brackets.
The National Land Classification (Trial), which is implemented on January 1, 2002, stipulates that the national land is divided into three categories, namely agricultural land, construction land, and unused land. In accordance with the "Interim Regulations on the Tax Tax of the People's Republic of China", taxation provisions for agricultural land and construction land are not involved in taxation for unused land.
There are 4,500 solar panels floating on the 12,400 square meters of water, while reservoirs with a surface area of 30,000 square meters and the full water sources of its surrounding rivers also have good cooling effects.
