6 FAQs about [The service life of solar panels on Chinese buildings]

How many solar panels will be recycled in China?

The cumulative installed capacity of solar power generation reached 425GW by the end of the first quarter of 2023. With such a rapid increase in installation volume, about 1.5 million tonnes of solar panels will need to be recycled in China in 2030. By 2050, the figure will rise to 20 million.

How long do solar panels last?

It is acknowledged that not much attention has been devoted to the end-of-life options for solar panels. The life of most commercially available panels is stated to exceed twenty years, and the lack of urgency in finding solutions may in part be attributed to the anticipated delay by which solutions are thought to be needed.

Why are solar panels so expensive in China?

Changes in the value of the raw materials used in solar panels are another factor. As of May 2023, the price of silicon in China has fallen by 30% from its 2022 peak of 320,000 yuan per tonne. Recyclers are reluctant to do business at the same cost.

Does China have a centralized photovoltaic system?

, since 2013, China’s newly added distributed photovoltaic installed capacity have fluctuated upward, and reached 29.28 GW by 2021, accounting for 53.4% of the total, and exceeding the centralized photovoltaic system for the first time in history.

Does China have a rural residential photovoltaic system?

China’s rural residential photovoltaic system has been greatly developed in recent years. However, most existing researches, are difficult to reflect the real development situation of the whole system.

How a photovoltaic system can save society?

In the case of a rural house in Shanxi Province, the annual power generation capacity of the photovoltaic system is 6,700 kwh, which can save 2,680 kg of standard coal for society in one year, thereby reducing the emissions of 6,681 kg of carbon dioxide, 201 kg of sulfur dioxide, 26.8 kg of nitrogen oxide, and 45.56 kg of dust (Yan 2018).
