The concept (or vision) of positive energy districts (PEDs) aims at supporting the energy transition in cities by fostering the development of both, planning processes and tools as well as technologies. Furthermore, the goal is to raise awareness about sustainable cities and to showcase the feasibility to reach a positive energy balance on the district level. While with improved efficiency of buildings, with heat pumps (HP) and on-site PV, a net positive energy balance is possible for new buildings, in existing or in high-density districts, reaching a positive energy balance on the footprint of the district is very challenging. Using a real case study from Austria and different archetype PEDs, electric load and supply curves are generated by means of dynamic simulation and are characterized with the aim to support decision-making in terms of minimum required energy efficiency level, HP system concepts and renewable energy integration. Even if the net energy balance is achieved, a significant gap in winter remains that has to be covered by the grid. Addressing the mismatch between energy demand in winter and RE generation in summer (so-called winter gap) is crucial for building a sustainable, affordable and resilient energy system. The grid stress cannot be relevantly reduced by increasing on-site PV and on-site storage but instead can be significantly limited by efficiency measures (electric peak load reduction by ca. 50 %) and is one of the most relevant KPIs to evaluate and optimize PEDs on the path to or transforming districts into PEDs.</div></div>","PeriodicalId":101174,"journal":{"name":"Solar Energy Advances","volume":"5 ","pages":"Article 100081"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143168224","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The integration of rooftop photovoltaic panels at domestic level, often underestimated, is a priority across Europe to meet targets of net-zero emissions by 2050. PV systems represent a crucial technology for renewable energy generation and mitigating climate change. However, their performance and potential are influenced by various factors, including environmental conditions, building parameters and geographical factors. This paper demonstrates multiple factors that affect PV potential in mild temperate oceanic climates, using Ireland as a representative case study. Unlike broad global reviews, this study contextualises PV system performance within the distinct environmental, architectural and socio-behavioural context of Ireland and similar climates. It provides an analysis of factors impacting rooftop PV efficiency, including solar irradiance, advancements in PV technologies, building typologies, roof orientation and tilt angle, shading, dust accumulation, cloud cover, snowfall and energy consumption behaviours. Additionally, the review examines recent trends such as artificial intelligence integration, self-consumption optimisation, battery storage and dynamic energy tariffs as critical components for enhancing PV system effectiveness. By combining insights from recent studies, the paper highlights the challenges posed by Ireland’s diffuse solar conditions, varying local climate and diverse housing stock, while identifying strategies for PV design improvements and energy-use behaviour adjustments. The study concludes with recommendations of development of integrated, site-specific PV frameworks that align technological, environmental, and socio-economic variables to optimise residential rooftop PV deployment in Ireland and comparable climates.</div></div>","PeriodicalId":101174,"journal":{"name":"Solar Energy Advances","volume":"5 ","pages":"Article 100111"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144312853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Scenarios aligned with the Carbon Neutral 2050 (CN2050) plan, developed under the Long-Term Energy Planning (PELP) program by the Chilean Ministry of Energy, were assessed using EnergyPLAN. In 2019, Punta Arenas emitted 1.32 million tonnes of carbon dioxide equivalent (CO₂eq), projected to rise to 2.2 million tonnes by 2050 under a business-as-usual (BAU) scenario, with annual costs of 947 million euros. Implementing PELP CN2050 measures reduces emissions to 1.2 million tonnes and costs to 560 million euros, demonstrating that decarbonization can be achieved alongside economic savings. This validates the PELP CN2050 plan's effectiveness, highlighting that renewable energy integration supports sustainability and economic benefits. Reductions are achieved through energy efficiency, technological changes, and integrating renewable energies—particularly wind and solar thermal—in industrial, transport, and residential sectors. Electrification and green hydrogen for motive, thermal, and transport applications are crucial. Two cases were evaluated: importing green hydrogen or producing it locally via renewable-powered electrolysers. Sensitivity analyses increasing wind capacity from 13 MW to 310 MW showed that higher renewable integration reduces CO₂eq emissions and costs, indicating a negative abatement cost. Further decarbonization could be achieved by incorporating cogeneration, district heating, and synthetic fuels.</div></div>","PeriodicalId":101174,"journal":{"name":"Solar Energy Advances","volume":"5 ","pages":"Article 100087"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143168219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In general, the market offers a limited range of viable alternatives for a number of specific applications. In this study, the 1,12-dodecanediol compound was evaluated as a PCM in its original ambient storage atmosphere. The physicochemical properties of a PCM ultimately determine the conditions under which it can be employed in a given application. Many of these properties, including phase change temperatures, enthalpies, specific heat, and temperature-time relationships, are determined using differential scanning calorimetry (DSC) instruments. In summary, the phase change temperature and enthalpies of 1,12-dodecanediol were found to be 80–76 °C and 238–237 J g⁻¹, respectively, for heating/cooling. Moreover, TGA is used to ascertain the maximum temperature that a common PCM is capable of withstanding. The first degradation temperature of 1,12-dodecanediol (220 °C) was considerable as compared to other organic PCMs. Further thermal analysis of a new PCM may involve thermal conductivity and its potential to increase using conventional additives. The investigation was conducted on 1,12-dodecanediol across the aforementioned aspects. The surface morphology of both the 1,12-dodecanediol and 1,12-dodecanediol/expanded graphite (EG) composites was examined below the phase change temperature using a polarized optical microscope (POM) to reveal surface morphology of 1,12-dodecanediol as the crystalline organic material.</div></div>","PeriodicalId":101174,"journal":{"name":"Solar Energy Advances","volume":"5 ","pages":"Article 100079"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142747256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Solar photovoltaic (PV) has become especially prominent in thematic research on energy these days. Research focusing on the keys to improving the energy efficiency of solar photovoltaics and managing the end-of-life issue, more specifically in materials recycling and reusing, is emerging in the recent era. Aligning with the UN-SDGs 7, 11, 12, and 13, a comprehensive survey is done about the advancements and challenges in solar photovoltaic technologies to emphasise enhancing efficiency and addressing end-of-life management for sustainable, clean energy. Solar PV efficiency, which is still low compared to competing technologies and depends on a large space to harness solar radiation, is severely affected by dusts and high irradiance in the middle east region. The current review shows a decrease in efficiency by 0.3 % to 0.5 % with a one-degree rise in temperature and a decrease in the output performance by 16 % to 24 % with 5 g/m² dust accumulation on the panel. Therefore, there is a demand for mitigating strategies, such as cooling and cleaning procedures, which are critical in improving the efficiency and lifespan of PV panels. The review also confirms that the remanufacturing strategy for PV is crucially important as the feedstock (e.g., silicon rocks) for PV panels is finite and also a large amount of toxic e-waste will be produced at the end of life. Around 75 million tonnes of e-waste (solar PV waste) could be generated by 2050. This review uniquely combines advanced computational analyses, experimental findings, and mitigation strategies for cooling, cleaning, and recycling, focusing on performance optimisation and sustainable end-of-life management of solar PV panels. The readers will be aware of practical insights and a detailed framework for enhancing solar PV technology and provide useful information to researchers, policymakers, and industry stakeholders to address the barriers to the rapid uptakes of PVs in a sustainable manner.</div></div>","PeriodicalId":101174,"journal":{"name":"Solar Energy Advances","volume":"5 ","pages":"Article 100084"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143169325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We observe pronounced warming across all thermal indices, with mean surface air temperatures rising by +0.25 °C per decade (<em>p</em> &lt; 0.001), accompanied by increases in maximum (+0.21 °C/decade) and minimum (+0.28 °C/decade) temperatures for the period 1958 to 2024. Photovoltaic (PV) cell operating temperatures mirror this trend, climbing by +0.26 °C/decade. We further found cumulative efficiency losses of 0.4 - 0.5 % per °C for crystalline silicon PV modules, compounding Yemen’s energy vulnerabilities. Counterintuitively, downwelling surface solar radiation (SRAD) remains stable with a near-zero trend (slope ≈ -0.00 W/m² yr^-1), while declining wind speeds of -0.002 ms yr^-1 reduce natural cooling of PV modules. Our spatiotemporal analysis reveals stark regional contrasts whereby coastal zones exhibit stable or increasing PV resource potential (PVres; +0.10 W/m²/year), while inland deserts like the Rub’ al Khali margins show declines of up to -0.10 W/m²/year, likely driven by intensifying dust aerosols and land degradation. Nationally, PVres shows no significant long-term trend (-0.043 W/m²/year, <em>p</em> = 0.070), obscuring these critical regional vulnerabilities. Seasonal extremes ranging from April peaks of 264 W/m² to December troughs of 201 W/m² highlight the necessity for adaptive energy storage systems. We identify a critical paradox wherein nationally stable solar resources mask spatially divergent risks requiring high-resolution energy planning. Coastal regions emerge as optimal for PV deployment, whereas inland areas necessitate dust-resilient technologies and hybrid systems.

In designing solar power plants, we must consider important details. This article explores the design of a 100-kW rooftop solar power plant, addressing challenges and selecting the best design, particularly focusing on the impact of bi-facial coefficients. One of the challenges is accurately assessing the amount of radiation received from the rear of the panels and optimizing the row spacing to prevent shading. Another challenge is determining the effective installation angles and the height of the panels above the ground to enhance bi-facial efficiency. Neglecting to properly configure this factor can lead to incorrect energy yield estimates and negatively affect the economic analysis of the designed project. The main objective is to create an appropriate design for bi-facial PV systems in PVsyst by considering several obstacles. These challenges include field segment shading, solar energy availability in different months, nearby shading, roof configuration and wiring, cable design, grounding system, protection system calculation, risk assessment, lighting, and installation of lightning rods for shadow measurement. Various software, such as AutoCAD, PVsyst, ETAP, PVLPC, Helioscope and Volta, were utilized in this study.
