China is now investing a lot of resources to develop clean energy. In terms of photovoltaic power generation, China has made a lot of achievements. China recently hit the world first. A few years ago, China's largest electric power floating photovoltaic power plant was connected to the grid, which reached 150 megawatts of power. The power station can generate 200 million degrees a year. It is equivalent to saving more than 70,000 tons of coal. This has sparked many netizens' concerns about whether throwing a board on water can generate electricity. What is the principle of this floating photovoltaic plant? The technology is simple in principle, with solar cells mounted on buoyancy tanks that float on water, but there are a number of technical hurdles to overcome before the technology can be used on a large scale, which is why China's achievement has caught the world's attention.
The technology of floating photovoltaic power stations with floating PV systems
actually is very simple. The photovoltaic power generation using solar cells itself can build on any stable surface. Therefore, it only needs to install bubbles and other buoyancy materials under the solar battery installation. It can float on the surface of the water. At the same time, it will take enough insulation measures to prevent the water in order to cause a short circuit. The floating photovoltaic power station also can be built. However, it was not until recent years that the power station received more attention. When compared to building on the land of the photovoltaic power station, the floating photovoltaic power station faces maintenance difficulties and the problem of high maintenance cost. China's achievements are for the application of this technology to find a new space. It can have greater benefits besides generating electricity.
The floating photovoltaic power station with the floating PV mounting system
in the area which China built is very special. It has no construction on rivers or the sea, but on a building in Huainan coal mining subsidence area, Anhui province. The subsided was collapsed by the underground coal mining subsidence work. At the same time, there formed a pond because of groundwater and the accumulation of rain water. However, a lot of pollution was caused by the mining work. There is hardly any aquatic life in the pond. There is only a large number of algae, causing serious pollution. Why is the floating photovoltaic power station built in this area? In fact, it shows the whimsy and ingenuity of Chinese engineers.
Theoretically, floating photovoltaic power station can be built on any water surface. However, the construction on this pond can play a bigger benefit. After the construction of a large number of solar cells can absorb a lot of sunlight, reduce the water of the pond and inhibit pond algae breeding. At the same time, a large number of solar battery covers can also prevent the pond water from losing. After China built the floating photovoltaic plant, it installed a large number of planting boxes around it, planted water hyacinth and other water-purifying plants, and scattered grass seeds and fish fry into the pond.
Under the dual role of the cover of these plants and animals and solar battery, the water quality has improved in recent years. All kinds of aquatic plants and animals have already appeared. It changed into a thriving small lake from an originally drab stinking pond, which reflects that the floating photovoltaic power station can bring extra income. In theory, it can be built on any water surface. However, in practice, if its impact on the water is used flexibly, floating PV plants can make a huge contribution to the improvement of water quality.
Now, China can build stronger power plants with larger capacity by flexibly using the characteristics of floating photovoltaic power stations. Some experts believe that the floating PV power station can be built in the reservoir surface. It reduces the evaporation loss of the reservoir, as well as the great power. China is now exploring floating photovoltaic power stations for the greater use of space.
