On July 31, with the successful grid-connection of the second phase of 500000 kilowatt photovoltaic project , the Dachaidan 1 million kilowatt photovoltaic project of Qinghai Company realized full-capacity grid-connected power generation.
The picture shows the site
of Dachaidan 1 million kilowatt photovoltaic project. The project is located in Dachaidan area, Haixi Prefecture, Qinghai Province. The average sunshine hours are 8.83 hours. The sunshine time is long, the light coverage is wide, and the natural endowment conditions of photovoltaic power generation are superior. With an investment of 4.38 billion yuan and an area of 1552.5 hectares, the project is divided into 137 sub-arrays, including 545 watts, 550 watts, 555 watts, 645 watts, 650 watts and 655 watts of monocrystalline silicon double-sided double-glass photovoltaic modules, 196 kilowatt and 300 kilowatt string inverters . Fixed brackets are used to install 137 6.5M VA box transformers, 47 collector lines and nearly 8000 kilometers of cables. After the project is put into operation, it is expected to contribute 1.793 billion kilowatt-hours of clean energy annually, which can meet the annual electricity consumption of nearly 1.6 million households. Saving 561000 tons of standard coal, reducing 6140 tons of sulfur dioxide emissions, 1.684 million tons of carbon dioxide emissions, 147 tons of carbon monoxide emissions, 6483 tons of nitrogen dioxide emissions and 7588 tons of smoke and dust emissions will further help to achieve the goal of "carbon peak, carbon neutralization". It is of great significance to build a new power system and promote local economic and social development.
