摘要:

在光伏(PV)技术进步的推动下,太阳能因其易于集成到建筑屋顶、立面和窗户上,已成为一种有前景的可再生能源。对于新兴城市而言,缺乏详细的街道级数据对有效评估建筑一体化光伏(BIPV)的潜力构成了挑战。为解决这一问题,本研究引入了SolarSAM,一种利用遥感影像和深度学习技术的新型BIPV评估方法,并以中国北方的一个新兴城市为例验证模型性能。在此过程中,SolarSAM使用文本提示引导的语义分割对不同建筑屋顶进行了分割。随后,利用这些分割数据和当地气候信息,分别为屋顶光伏、立面一体化光伏和光伏窗系统开发了独立的光伏模型。研究评估了BIPV安装潜力、太阳能发电量以及城市范围的电力自给能力,结果显示年BIPV发电潜力超过该市总用电量的2.5倍。研究还进行了经济和环境分析,包括平准化度电成本和碳减排计算,比较了不同建筑类别下的各种BIPV系统。这些发现证明了模型的性能,并揭示了BIPV发电在未来具有的潜力。

英文摘要:

Driven by advancements in photovoltaic (PV) technology, solar energy has emerged as a promising renewable energy source, due to its ease of integration onto building rooftops, facades, and windows. For the emerging cities, the lack of detailed street-level data presents a challenge for effectively assessing the potential of building-integrated photovoltaic (BIPV). To address this, this study introduces SolarSAM, a novel BIPV evaluation method that leverages remote sensing imagery and deep learning techniques, and an emerging city in northern China is utilized to validate the model performance. During the process, SolarSAM segmented various building rooftops using text prompt guided semantic segmentation. Separate PV models were then developed for Rooftop PV, Facade-integrated PV, and PV windows systems, using this segmented data and local climate information. The potential for BIPV installation, solar power generation, and city-wide power self-sufficiency were assessed, revealing that the annual BIPV power generation potential surpassed the city's total electricity consumption by a factor of 2.5. Economic and environmental analysis were also conducted, including levelized cost of electricity and carbon reduction calculations, comparing different BIPV systems across various building categories. These findings demonstrated the model's performance and reveled the potential of BIPV power generation in the future.
