A substantial share is distributed, and key information – such as their installed capacity, precise location, tilt, and azimuth – are often lacking or inaccurate. Therefore, obtaining accurate data on existing PV systems become increasingly critical to determine optimal locations for adding new PV capacity, in terms of ensuring grid stability. Recent advances in identifying and segmenting solar energy systems, using aerial imagery, point to a logical next step; enhancing the modelling of tilts and azimuths, as these influence the power output significantly. Therefore, a method is proposed that derives the tilt and azimuth of solar energy systems using Light Detection and Ranging (LiDAR) data. Polygons representing solar energy systems, identified in aerial images, are orthorectified to LiDAR data and then linear regression is applied to determine the orientation. The method is evaluated for 3’500 Swedish solar energy systems previously identified in aerial images, with a manually derived ground truth azimuth dataset. For 91%–95% of the systems, the model accurately estimated the azimuth within a margin of 3°. Furthermore, the distribution of azimuths was more narrow for solar thermal systems than for PV systems. A ground truth of the tilt for a subset of 39 systems gave a mean absolute error of 3.6°. The proposed method is believed to provide more accurate PV metadata to, e.g., aggregators and grid operators, enabling more precise PV power simulations and forecasts, in turn leading to better grid operation and planning.</div></div>","PeriodicalId":428,"journal":{"name":"Solar Energy","volume":"291 ","pages":"Article 113344"},"PeriodicalIF":6.0,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143549501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to the complex environmental conditions at engineering sites and the small scale of microcracks, these defects are often confused with scratches or impurities on the surface of PV cells, leading to low detection efficiency and insufficient accuracy. This makes timely maintenance difficult. To address this issue, this thesis proposes a semantic segmentation method for PV cells based on polarization imaging, derived from the underlying mechanism of PV cell crack formation. In this approach, polarization imaging technology is utilized to capture three single-channel images of PV cells: polarization intensity (I), degree of polarization (DOP), and polarization quadrature (Q). These images are then stacked into different channels to create a comprehensive dataset. The dataset is annotated for training purposes, followed by an analysis of the texture features associated with microcrack defects. Additionally, the traditional U-Net architecture is enhanced to better exploit the unique features of the polarized three-channel images. Experimental results demonstrate that the proposed method outperforms existing semantic segmentation networks, showing excellent performance in microcrack defect segmentation in PV cells.</div></div>","PeriodicalId":428,"journal":{"name":"Solar Energy","volume":"291 ","pages":"Article 113364"},"PeriodicalIF":6.0,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143549565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared to rooftops and flat ground, wind filed on hilly terrain is more complex and can vary significantly from the bottom to top of a hill. Consequently, terrain interference must be considered when estimating the wind effects of hill-mounted PV panels, which complicates the estimation of design wind loads for PV power plants. Most previous studies have focused on wind effects on the ground- and roof-mounted PV panels, while limited attention has been given to conditions specific to hilly terrains. To address this gap, this study employed wind tunnel testing to investigate the wind load characteristics of the PV panel arrays mounted on the typical cosine-shaped hills. The effects of hill slope and ground clearance on aerodynamic characteristics were analyzed. The results show that hill slope significantly affects the wind loads on hill-mounted PV array; specifically, increasing the slope increases the positive and negative peak pressures on the panels at the hilltop by 19.0 % and 27.5 %, respectively. For PV panels on a hillside, an increase in ground clearance leads to higher peak wind pressures and wind suctions. This effect becomes more pronounced under steeper slopes. Accordingly, recommendations for peak net pressure coefficients for PV panel array with hill slopes of 15° and 30° were proposed, to facilitate a cost-effective and safe wind-resistant design of support structures.</div></div>","PeriodicalId":428,"journal":{"name":"Solar Energy","volume":"291 ","pages":"Article 113256"},"PeriodicalIF":6.0,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143528846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, no design indicator exists that combines SA or SF with thermal loss considerations.

Benchmarking the PSPR and SGLR against transient simulation results revealed their superior effectiveness in ranking design options by expected net solar heat gains compared to SA and SF.

In analysing what affects residential PV adoption decisions, this study adds emotional to cognitive factors such as cost perceptions. Thereby, it addresses a research gap on emotions in sustainability transitions. Furthermore, building on a nascent stream of recent literature, this research considers spillover effects from having adopted other clean energy solutions, heat pumps and electric vehicles, on PV adoption. The study uses ordinary least squares regression analysis based on survey data collected in Germany (n = 1003) to investigate the roles of three variable groups: emotions, cost perceptions, and spillover effects. The results show that the emotions pride (β ≈ 0.2) and happiness (β ≈ 0.2) and the adoption of a heat pump (β ≈ 0.2) and an electric vehicle (β ≈ 0.3) are positively and statistically significantly related to PV adoption. Operating cost perceptions (β ≈ −0.1) are negatively connected to PV adoption. With these insights, the study highlights the importance of including emotional and spillover factors in the analysis of factors influencing PV adoption.
