The goal of this study was to assess the impact of varying PV transparency on strawberry yield and growth under Cd-Te PV modules, and to evaluate the potential of agrivoltaics as a sustainable solution for strawberry production in northern climates. Seven levels of transparency (10%, 30%, 40%, 50%, 60%, 70%, and 80%) were tested, which resulted in varying photosynthetically active radiation (PAR) values under each PV module type. Modules were tested in a controlled environment designed to replicate outdoor conditions of London Ontario, with regulated temperature and lighting. Strawberry fresh weight, plant height, leaf count, and flower count were quantified. The results indicate that strawberries grown under 70% transparency PV exhibited a fresh weight 140.6% of the average control. Additionally, 40% transparency maintained a greater than 80% yield making them viable in all regions with agrivoltaics yield mandates. Increased transparency in PV modules also correlated with a higher number of leaves, while height correlation was complex. If Canadian strawberry farms converted to agrivoltaics, between 595 and 1,786 GWh of solar electricity could be generated and globally strawberry agrivoltaics offer an electrical potential ranging from 58 to 173 TWh. The adoption of agrivoltaics in the strawberry sector could facilitate energy self-sufficiency and transform it into a net electricity exporter, generating additional revenue for farmers.</div></div>","PeriodicalId":428,"journal":{"name":"Solar Energy","volume":"290 ","pages":"Article 113375"},"PeriodicalIF":6.0,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143454160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using first-principles density functional theory calculations, we show that SMO with cubic symmetry demonstrates a direct bandgap character (∼0.62 eV), exceptional absorption behaviour (∼10<sup>5</sup> cm<sup>−1</sup> in the visible range), substantial dielectric constant (∼11) and a reasonably small exciton binding energy (∼44 meV) promising a sizeable photovoltaic response (PCE<sub>SLME</sub> ∼ 16 %).

This research introduces SolarMTNet, a novel multitask dense-prediction network designed for rooftop solar potential prediction using only aerial images. Unlike previous studies that focus on small manually labeled datasets (approximately 2000 scenes) and only segment rooftop orientations while typically assuming constant slopes, SolarMTNet simultaneously segments both orientations and slopes, enhancing the accuracy of solar potential estimations by 40%. SolarMTNet leverages a large, automatically labeled dataset (up to 280000 scenes) created from open-source Swiss geospatial and aerial data, significantly improving generalization. The model is trained on rooftop data from the Zurich and Geneva cantons and cross-validated on the Canton of Vaud, Switzerland. The results show a mean Intersection over Union (mIoU) of 0.67 for orientation segmentation and 0.40 for slope segmentation. The estimated irradiance exhibits an absolute mean percentage difference of only 5% compared to real solar cadaster data derived from detailed model-based calculations, primarily due to shading issues.
