Abstract

The impact of photovoltaic power plants (PVs) on ambient temperature has received global research attention. However, existing reports predominantly focus on ground photovoltaic power plants (GPVs), with limited attention to water photovoltaic power plants (WPVs). As a new type of PVs, the influence of WPVs on nearby water surface temperature (WST) remains unclear. Utilizing 15 WPVs in China as case studies, this study assessed the effect of WPVs on nearby WST through remote sensing techniques. The findings revealed that WPVs have a significant heating effect ( < 0.001) on the WST in the nearby zone (0–120 m from the photovoltaic panels) compared to the distant water (120–240 m from the photovoltaic panels), indicating that WPVs can modify the thermal environment of adjacent water. Furthermore, we further found that the photovoltaic coverage ratio is significantly ( < 0.05) positively correlated with the heating effect of WPVs on nearby WST. This paper highlights the effectiveness of remote sensing techniques in evaluating the impact of photovoltaics on surrounding WST. Considering the potential impact of the photovoltaic heating effect on the aquatic ecological environment, we recommend carefully considering the necessity and appropriate area proportion of WPVs in specific water.

利用遥感技术评估水上光伏发电对附近水面温度的影响

光伏电站（PVs）对环境温度的影响已受到全球研究的关注。然而，现有报告主要关注地面光伏电站（GPV），对水上光伏电站（WPV）的关注有限。作为一种新型光伏电站，水上光伏电站对附近水面温度（WST）的影响尚不清楚。本研究以中国的 15 个水上光伏电站为案例，通过遥感技术评估了水上光伏电站对附近水面温度的影响。研究结果表明，与远处水域（距离光伏板 120-240 米）相比，近处水域（距离光伏板 0-120 米）的 WPV 对附近水域的 WST 有显著的加热效应（< 0.001），这表明 WPV 可以改变附近水域的热环境。此外，我们还进一步发现，光伏覆盖率与 WPV 对附近 WST 的加热效应呈显著正相关（< 0.05）。本文强调了遥感技术在评估光伏发电对周围水体温度影响方面的有效性。考虑到光伏加热效应对水生态环境的潜在影响，我们建议在具体水域中仔细考虑安装 WPV 的必要性和适当的面积比例。

期刊介绍： The COSPAR publication Advances in Space Research (ASR) is an open journal covering all areas of space research including: space studies of the Earth''s surface, meteorology, climate, the Earth-Moon system, planets and small bodies of the solar system, upper atmospheres, ionospheres and magnetospheres of the Earth and planets including reference atmospheres, space plasmas in the solar system, astrophysics from space, materials sciences in space, fundamental physics in space, space debris, space weather, Earth observations of space phenomena, etc. NB: Please note that manuscripts related to life sciences as related to space are no more accepted for submission to Advances in Space Research. Such manuscripts should now be submitted to the new COSPAR Journal Life Sciences in Space Research (LSSR). All submissions are reviewed by two scientists in the field. COSPAR is an interdisciplinary scientific organization concerned with the progress of space research on an international scale. Operating under the rules of ICSU, COSPAR ignores political considerations and considers all questions solely from the scientific viewpoint.
