Grow towards the sun, strive for "light" and "green".
Light, the source of power for upward growth, how to use light to empower the road of green and high-quality development, Lu'an, which "chases the light and moves forward", has given the answer of "green energy surging".
As of the end of August 2024, the city has built a total of 3,256,500 square meters of photovoltaic building integration projects with an installed capacity of 356.73 megawatts.
Housing is transformed into a "power plant" and there is a profit from self-consumption
Dozens of high-rise residential buildings, building thousands of photovoltaic modules, like a green "power plant", this is the first photovoltaic residential building pilot application project under construction in Lu'an City - the revitalization of · Wenhefu Phase II photovoltaic power generation project.
How much "energy" will be generated by the "cross-border" linkage between photovoltaic and buildings?
"The project has an installed capacity of 394.02 kilowatts, a total of 1,194 polycrystalline silicon photovoltaic modules are installed, and the annual power generation is about 503,000 kWh, and the total power generation is expected to reach 12.575 million kWh in 25 years, which is equivalent to saving 4,401 tons of standard coal, reducing carbon dioxide emissions by 12,573 tons, and reducing sulfur dioxide emissions by 378 tons, with obvious energy saving and emission reduction effects." Wang Biao is the person in charge of the installation of the project, and the set of data he said is eye-catching.
The reporter saw at the scene that the construction personnel are seizing the favorable opportunity of fine weather to install photovoltaic modules in an orderly manner.
According to reports, the project adopts the consumption mode of "spontaneous self-consumption and surplus power grid", and the direct current energy generated by the photovoltaic system is converted into three-phase alternating current by the inverter and connected to the internal power grid of the community for public supporting electricity. In the case of surplus electricity, the national grid will be connected to the grid, and the related income generated will also be fed back to the owners of the community.
As a clean energy source, photovoltaic power generation is gradually becoming an important driving force for rural revitalization. Wei'an Village, Yu'an District, will be photovoltaic power generation and green farmhouse ingenuity combination can be described as unique, the former roof tiles, with the blessing of science and technology, replaced into "photovoltaic tiles", can not only shade the rain but also generate electricity, sunny days to enjoy the "sunbathing" of photovoltaic tiles, absorb light energy into electricity, light up the warm new houses.
"In the design and construction of green farmhouses, we optimized the energy consumption structure of farmhouse buildings, applied renewable energy to farmhouse buildings, and adopted the 'photovoltaic tile' thin film power generation technology of photovoltaic power generation and building integration to build farmhouses into a 'light, storage, direct and flexible' building integrating photovoltaic power generation, energy storage, DC distribution (charging) and flexible electricity consumption." The relevant staff of Anhui Gaodi Circular Economy Industrial Park Co., Ltd. told reporters that the green farmhouse has achieved self-sufficiency in heating, lighting, refrigeration, kitchen and other electricity consumption, and the surplus electricity can also be connected to the Internet, and the income generated belongs to the village collective.
"Blue Ocean" chases the light forward and highlights the "new quality of productivity"
Green development is the background color of high-quality development, and new quality productivity itself is green productivity. How to accelerate the development of new quality productivity? On the roof of the park in Lu'an Development Zone, solar energy is used for photovoltaic power generation, giving a model.
Against the backdrop of the blue sky and white clouds, on the roof of the factory of Lu'an Zhongcai Pipeline Technology Co., Ltd., the brand-new photovoltaic equipment is neatly arranged and shining, and the photovoltaic panels converge into a "blue ocean". In order to better reduce costs, the company finally cooperated with Huadian in the development of rooftop photovoltaic projects through understanding and market research of photovoltaic projects in the early stage, using a rooftop area of about 130,000 square meters to develop and build a photovoltaic system with a capacity of about 10.5 megawatts, with an annual power generation of about 10 million kWh. In November last year, the construction of the photovoltaic project started, and in April this year, it reached full capacity grid-connected operation.
As of July this year, the total power generation capacity of the east and west areas of Zhongcai pipeline is 4,716,500 kWh, and the consumption is 4,349,500 kWh, with a consumption ratio of more than 92%.
Nowadays, following the drone from a high altitude, from urban high-rise buildings to rural farmhouses, from universities to production plants, photovoltaic equipment has been installed on many rooftops of Lu'an, demonstrating the huge potential of green productivity.
In the beautiful Moon Island, the Dabie Mountain Revitalization and Development Science and Technology Innovation Center (Science and Technology Building) of West Anhui University is about to be delivered, and the building is also the city's first photovoltaic building integration "photovoltaic storage, direct and flexible" pilot project.
According to Huang Xingyun, the relevant person in charge of the project, the science and technology building is designed in accordance with the two-star standard of green building, and the photovoltaic power generation system is arranged on the main building and podium roof, and the electric energy is mainly used for the lighting of the public space of the building and the power supply of central air conditioning in some areas.
"A total of 400 monocrystalline silicon photovoltaic modules are installed on the roof, of which 80 photovoltaic modules are used in photovoltaic air conditioning systems, using photovoltaic storage, direct and flexible technology. The remaining 320 photovoltaic modules are equipped with storage batteries to form an off-grid photovoltaic system. The estimated installed capacity is 100 kilowatts, and the annual power generation is about 105,000 kWh based on the annual effective sunlight of 1,050 hours in Lu'an. Huang Xingyun said.
Green energy surging "empowers" the road of high-quality development
In recent years, Lu'an City has adhered to the concept of "ecological priority and green development", and integrated the "double carbon" requirements into the integrated application of photovoltaic proposals, and has achieved remarkable results.
Liu Xiaoqing, director of the Municipal Building Industry Center of Lu'an Housing and Urban-Rural Development Bureau, said that photovoltaic building integration is an important measure to achieve the national dual carbon goal, and Lu'an City has carried out building photovoltaic applications since 2021, and in September of that year, Jinzhai County was identified by the National Energy Administration as a pilot county for the development of rooftop distributed photovoltaic in the whole county, and began to promote the application of rooftop distributed photovoltaic in the whole county. In 2022, we will seize the policy opportunity to guide Shucheng County to successfully create a pilot city (low-carbon area) for green development of urban and rural construction in Anhui Province, vigorously promote the application of photovoltaic building integration, and have gradually promoted distributed photovoltaic power generation in industrial buildings, public buildings and rural residential buildings in the city. As of the end of August 2024, the city has built a total of 3,256,500 square meters of BIPV projects, with an installed capacity of 356.73 megawatts.
