Recently, the rooftop distributed photovoltaic construction project in Yuqing County, Zunyi City, Guizhou Province, has made significant progress. After completing the initial procurement of materials and clearing the rooftops, the project has entered a crucial phase involving site measurement, line marking, and base installation. This foundation work is essential for the subsequent assembly of photovoltaic panels, aiming to accelerate production and contribute to local green development.
The construction site is bustling with activity. On one rooftop, workers are using professional equipment to meticulously collect data, mark, and map the flat surfaces, ensuring precise installation of the photovoltaic components. Simultaneously, they are leveraging the principle of leverage to collaboratively transport concrete blocks, reinforcing the safety of the equipment’s load-bearing capacity. On another rooftop, the construction team is focused on core structural tasks, welding the photovoltaic support bases according to strict standards to secure the foundation for the safe installation of the solar panels. Each stage is progressing in an orderly manner, demonstrating the project’s “accelerated pace” of construction.
According to Wang Zixuan, the deputy general manager of the Yuqing County Industrial Development Group, “The rooftop distributed photovoltaic project we are planning and constructing in Yuqing County is significant in scale, with a total investment of approximately 176 million yuan. The designed area covers about 220,000 square meters, with a total installed capacity of 45 megawatts. We are currently advancing the first phase of the project.”
The project spans two towns, Baini and Longxi, and primarily utilizes rooftops of industrial standard factories and public buildings. The effective installation area reaches 193,300 square meters. The project will utilize 630Wp monocrystalline silicon BAPV smart photovoltaic tiles, constructing a 45-megawatt rooftop distributed photovoltaic power station, along with supporting equipment for power distribution, photovoltaic construction, and factory reinforcement. Based on the installed capacity and installation locations, the project is divided into 10 segments, with a total of 75,428 photovoltaic modules to be installed. The overall construction period is expected to last one year.
Construction began in early September 2025, with a planned completion date of December 30, 2025. Once operational, the project is expected to generate approximately 40 million kWh annually. Compared to coal-fired power generation, this will save a substantial amount of coal each year and significantly reduce emissions of CO, SO₂, CO₂, nitrogen oxides, smoke, ash, and other pollutants. In its first year, the CO₂ reduction is anticipated to reach 26,032.27 tons, which is crucial for improving the regional ecological environment.
The project’s operational model is equally impressive. “In the future, we will adopt a ‘self-consumption and surplus power online’ model. Enterprises within the park will prioritize using the electricity generated by the project to meet their production and daily electricity needs. When the electricity consumption exceeds the enterprises’ requirements, the surplus power will be connected to the national grid, facilitating rational allocation and efficient utilization of electricity,” Wang Zixuan stated. This approach not only ensures power supply for the enterprises but also contributes clean energy to the national grid.
The advancement of this project will not only support Yuqing County’s low-carbon transition and improve air quality but also promote local economic development, achieving a “win-win” scenario for ecological and economic benefits, thereby contributing to the green and low-carbon development of Guizhou.
