Abstract

To combat global climate change requires fast deployment of photovoltaics (PV), especially for Belt and Road Initiative (BRI) countries. However, PV systems are highly material-intensive with significant waste, underscoring the need for high-resolution material stock mapping to enhance future recycling. Here, we develop an integrated framework that combines multi-source geographical data, to monitor PV material stocks at facility level in China during 2010–2019. The results indicate nearly 86 % (108 GW) of installed capacity concentrated in northwest, north, central, and east China in 2019, with total aluminum exceeding 1.8 million tonnes (Mt), followed by silicon at 87 kilo tonnes (kt), copper at 81 kt, and silver at 6 kt, almost half the PV installed capacity (61.4 GW) with 5.6 Mt PV panels are over 50 km from urban areas, emphasizing the necessity of high-resolution PV panel monitoring and its application in managing those emerging but diverse waste sources.

利用多源地理数据监测中国太阳能电站在用库存和材料回收潜力

应对全球气候变化需要快速部署光伏技术（PV），尤其是在 "一带一路 "倡议（BRI）国家。然而，光伏系统是高度材料密集型系统，浪费严重，因此需要绘制高分辨率的材料库存图，以加强未来的回收利用。在此，我们开发了一个结合多源地理数据的综合框架，以监测 2010-2019 年期间中国设施层面的光伏材料库存。结果表明，2019 年中国近 86% 的光伏装机容量（108 千兆瓦）集中在西北、华北、华中和华东地区，铝的总产量超过 180 万吨，其次是硅 87 千吨、铜 81 千吨和银 6 千吨，近一半的光伏装机容量（61.4 千兆瓦）和 560 万吨的光伏电池板距离城市地区超过 50 公里，这强调了高分辨率光伏电池板监测及其在管理这些新兴但多样的废物源方面应用的必要性。

期刊介绍： The journal Resources, Conservation & Recycling welcomes contributions from research, which consider sustainable management and conservation of resources. The journal prioritizes understanding the transformation processes crucial for transitioning toward more sustainable production and consumption systems. It highlights technological, economic, institutional, and policy aspects related to specific resource management practices such as conservation, recycling, and resource substitution, as well as broader strategies like improving resource productivity and restructuring production and consumption patterns. Contributions may address regional, national, or international scales and can range from individual resources or technologies to entire sectors or systems. Authors are encouraged to explore scientific and methodological issues alongside practical, environmental, and economic implications. However, manuscripts focusing solely on laboratory experiments without discussing their broader implications will not be considered for publication in the journal.
