屋顶太阳能光伏（PV）系统可以为欧洲的能源转型做出重大贡献。实现这一潜力给政策和电力系统规划层面带来了挑战。为了解决这个问题，作者开发了一种地理空间明确的方法，利用欧盟建筑存量的最新空间信息来量化光伏系统的可用屋顶面积。为此，它将基于卫星的统计数据源与机器学习相结合，以整个欧盟 (EU) 100m 的空间分辨率对屋顶光伏发电的技术潜力进行可靠的评估。它使用特定国家的参数估算平准化电力成本 (LCOE)，并将其与最新的家庭电价进行比较。结果显示，欧盟屋顶每年有可能产生 680 太瓦时的太阳能电力（占当前电力消耗的 24.4%），其中三分之二的成本低于当前的住宅电价。国家汇总结果说明了电价低、投资利率高的国家在具有成本效益的屋顶系统方面存在的障碍，并提供了如何解决这些问题的指示。
Rooftop solar photovoltaic (PV) systems can make a significant contribution to Europe's energy transition. Realising this potential raises challenges at policy and electricity system planning level. To address this, the authors have developed a geospatially explicit methodology using up-to-date spatial information of the EU building stock to quantify the available rooftop area for PV systems. To do this, it combines satellite-based and statistical data sources with machine learning to provide a reliable assessment of the technical potential for rooftop PV electricity production with a spatial resolution of 100m across the European Union (EU). It estimates the levelised cost of electricity (LCOE) using country-specific parameters and compares it to the latest household electricity prices. The results show that the EU rooftops could potentially produce 680 TWh of solar electricity annually (representing 24.4% of current electricity consumption), two thirds of which at a cost lower than the current residential tariffs. Country aggregated results illustrate existing barriers for cost-effective rooftop systems in countries with low electricity prices and high investment interest rates, as well as provide indications on how to address these.
