This old power station, located at the Gansu Institute of Renewable Energy, is the oldest surviving photovoltaic power station in China. Established in 1983 in Xiaocha Village, Yuanzi Township, Yuzhong County, Lanzhou City, Gansu Province, it was later relocated to the Gansu Institute of Renewable Energy and has a history of 40 years.
How long can a photovoltaic power station actually be used? The exact number is currently unknown, but a power station located in Lanzhou, Gansu, has answered this question in another way.
Longi Green Energy, the Gansu Institute of Natural Energy, and Xinhua News Agency recently jointly hosted the "With Initial Heart, Respect Initial Heart: Forty Years of Chinese Photovoltaics" event, visiting China's oldest existing photovoltaic power station. Reporters visited the Gansu Institute of Natural Energy to explore China's oldest existing photovoltaic power station.
This old power station, located at the Gansu Institute of Natural Energy, is the oldest existing photovoltaic power station in China. The power station was completed in Xiaocha Village, Yuanzi Township, Yuzhong County, Lanzhou City, Gansu Province in 1983, and later relocated to the Gansu Institute of Natural Energy. It has a history of 40 years.

According to reports, Xiaocha Village, Yuanzi Township, Yuzhong County, Lanzhou City, Gansu Province, was one of the poorest areas in Gansu at that time, located in the mountains at an altitude of 2600 meters, with very inconvenient transportation. Before 1983, due to the lack of electricity supply, people relied on bean oil lamps, kerosene lamps, and candles for lighting. However, in this year, the completion of a photovoltaic power station brought electricity to Xiaocha Village for the first time. In 1983, China's first 10kW solar photovoltaic power station was established here, bringing electricity and light to 130 households and thousands of people.
According to Li Shimin, vice chairman of the Photovoltaic Professional Committee of the China Renewable Energy Society, the photovoltaic modules of this power station use 36 single-crystal 102X102 velvet surface cells, with a single module rated output power of 45 peak watts, an installed capacity of 10 kilopeak watts, and 200 900 Ah batteries to form a 200-volt DC battery pack.
Today, in the northwest region, after 40 years of harsh weather, including cold and heat and sandstorms, this 10kW photovoltaic power station is still operating stably and continuously generating electricity, maintaining a power of 7kW.
Shi Zhengrong, a professor at Shanghai University of Electric Power, said that the 40-year-old photovoltaic power station in Gansu has verified that crystalline silicon photovoltaic products are indeed reliable. "The industry provides a 25-year warranty for photovoltaic modules. The fact that it has lasted 40 years proves that 25 years is not a problem, and it can operate for even longer."
Li Zhenguo, founder and president of Longi Green Energy, further pointed out: "The actual financial returns of this photovoltaic power station are better than our financial model. This means that our original calculations, whether it is the energy recovery cycle or the material recovery cycle, these indicators will be better than we predicted in the future."
Li Baoshan, special advisor to the council chairman of the China Renewable Energy Society, pointed out that over the decades, China's photovoltaic development has grown from small to large, from weak to strong, experiencing various changes and trials, and has now become a business card for China.
At the Gansu Institute of Natural Energy, reporters also saw many well-preserved solar component products. These photovoltaic "old objects" record the bits and pieces and progress of solar energy development over the past few decades. "Looking back at the history of photovoltaic development, renewable energy technologies have been more widely developed and applied, especially the rapid development of solar photovoltaic technology has significantly reduced the cost of solar power generation, and it has become an important alternative to traditional energy." said Zhou Jianping, director of the Gansu Institute of Natural Energy.
In Zhou Jianping's view, this old photovoltaic power station has developed along with the development of China's and the world's photovoltaic industry, blooming as the earliest built and longest running photovoltaic power station in the history of Chinese photovoltaics, and has also accumulated rich experience and research results for the long-term use of Chinese photovoltaic power stations.
"The history of China's photovoltaic development is far more than 40 years, and currently, it has only taken the first step, and there is still a long way to go. Solar power generation is a permanent topic, and human civilization cannot be separated from photovoltaic power generation." said Li Shimin.
