China's largest solar power station, covering 609 square km, the area close to the size of a Singapore
You are now looking at the largest solar power plant in China - 609 square kilometers, almost as big as Singapore. With an investment of about $10 billion, this project will be the world's largest solar farm and energy storage station in the next decade. It will not only provide the world with a large amount of electricity, but also deliver energy to the grid. At the same time, it will also reduce CO2 emissions. This is the largest photovoltaic power generation base in China - Qinghai Talatan Solar Power Station.
Qinghai province Hainan Tibetan autonomous prefecture republican county tara beach once for the sandy land area of 98.5% of the semi-sandy grass, it is not only barren, but also seriously endanger the surrounding Yellow River ecological zone. Due to the dry climate, pasture degradation and other reasons, herders can only graze mainly, rely on natural food to maintain their livelihood. 1990s, the local people use solar energy for breeding, animal husbandry has been rapid development. The income of herders has been increasing. However, as the photovoltaic industry in Qinghai Province began to promote in a big way, the pastoral industry here can be developed sustainably, the ecology is gradually recovering, and even the economy is further developed.
Republican County of Qinghai Province is located at the southern end of Qaidam Basin, which not only has an average altitude of nearly 3000 meters, but also has a serious lack of oxygen content, accounting for only 64% of the plain area. Rainfall is still very scarce here in Tara Beach, and precipitation cannot even meet the daily growth needs of the bushes.
Therefore, more than 10 years ago, there was no grass here, and the vast Gobi and the flying sand were the most common scenes here. Nowadays, as people become more aware of environmental protection, the ecological environment here has gradually improved. However, the sandstorm still happens from time to time because the problem of land sanding has not been solved. In order to make a living, the herders have to move to another place and choose a place with more luxuriant grass for their cattle and sheep.
However the height of Tara Beach also means closer to the sun and more abundant daily. So in such a very sunny season, Tara Beach will have more time to enjoy and relish the beauty and warmth that nature brings. Of course, this is just an illusion. Tala Beach is located in the eastern plateau of Qinghai. Most areas in Qinghai province have an average of about 1600 hours of sunshine per year, and Tala Tan even more so, but it has a unique advantage in the field of solar power generation.
That's why in 2012, China's first 10-megawatt solar power base was built in Talaatan, which has covered a total area of 609.6 square kilometers from the original 77.9 square kilometers to date. One very special thing about this country is its large area. It consists of two parts: one is called the Taklamakan Desert Region; the other is called the Qinghai Province, and there are many areas called the "Roof of the World" - the Qinghai-Tibet Plateau. It is the same size as Singapore. This is also the reason why Qinghai Talaatan PV Power Station is the largest PV power generation base in China.
At the Tara Beach PV power station in Qinghai Province, rows of solar PV modules are arranged in concentric circles, chasing the sunlight like sunflowers, not only replacing the bare sandstone ground, but also playing a role in blocking and reducing the wind speed here. "This is because direct sunlight hits the panels to generate a lot of heat, which raises their temperature, and then absorbs and transfers heat through the heat absorber." Wang Jianming, a researcher from the Qinghai Meteorological Bureau, said. Due to the low water vapor content in the air. And the shaded part of the PV panel also reduces the amount of water evaporation by even 30%.
In addition, the characteristics of the solar panels need to be cleaned regularly will also increase the amount of watering, because the moisture seeping out during cleaning will irrigate the plants here as regularly. But if not cleaned in time, this moisture will form a water film on the ground, which will adversely affect the growth of crops. So to prevent this from happening, we must irrigate frequently. However, due to the weather, it is not possible to irrigate every day. As a result, the grass in Tara Beach grows slowly and the grass is getting bigger and bigger, plus the planting of highland ecological type crops such as snow chrysanthemum and turbinia according to the soil and light conditions of this place, the whole ecological environment has improved greatly.
In addition, because the grass is really growing too well, it highly affects the solar power generation, and in the winter when the sky is dry, there are many dry grasses which are also fire hazards. If the grassland is not properly protected and utilized again, then the grassland may become barren due to overgrazing. Therefore, how to make the grassland healthy and sustainable is a question we need to think about. Therefore, the company in Tara Beach PV Park has come up with a solution, which is to call on the nearby herdsmen to raise "PV sheep" in the PV Park. This will not only weed and eliminate fire hazards, but also save the cost of weeding, so that nearby herdsmen do not need to move to other places and increase their economic income by raising "solar sheep".
