This study examined autonomous photovoltaic systems with batteries as an alternative to Benin's public electricity grid. Five different load profiles with the same daily energy consumption were investigated, and their effect on the PV/battery system cost was estimated. The PV/battery system's sizing was optimized using decision criteria such as cost of energy (COE) and loss of power supply probability (LPSP). The multi-objective problem was solved using the non-dominated genetic sorting algorithm II (NSGA-II) metaheuristic. The effect of geographical location on the cost of PV/battery systems was also investigated. The findings revealed that load profiles that prioritized deferred energy consumption had higher energy costs than those that prioritized direct consumption from solar panels. The PV/battery systems proved to be less expensive for consumers than the tariffs currently charged by Benin's national grid, regardless of geographical location. The widespread use of these systems could significantly reduce greenhouse gas emissions. Consequently, substituting the electricity grid with photovoltaic/battery systems for the five load profiles investigated in this research could effectively avoid the release of around 1.94 tons of carbon dioxide into the atmosphere.</div></div>","PeriodicalId":101173,"journal":{"name":"Solar Compass","volume":"16 ","pages":"Article 100140"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145020356","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}

This growth has made it even more important to have good cleaning methods, since dust and other particles can cut PV performance by 20–50%, and even 80% in dry conditions. This evaluation looks at many ways to clean, including as robotic systems, electrostatic methods, ultrasonic techniques, and self-cleaning coatings. It looks at how well they clean, how much water and energy usage, how they affect panels over time, and how much they cost to run. The results show that robotic and electrostatic cleaning can bring back 95–98% of panel efficiency, although they use more energy (0.5–2% of PV output) and cost more money. Passive nanostructured coatings cut soiling losses by 50–70% and preserve water, but they break down when exposed to UV light for a long time. Combining robotics with coatings in hybrid approaches makes cleaning less frequent while keeping high efficiency.

This not only optimizes land use but also enhances food and energy security. Since Agri-PV is closely linked with crop cultivation, it is not solely about energy generation but also requires careful consideration of crop suitability within Agri-PV installations. Despite its significance, there is limited information available to guide decision-making for crop selection in Agri-PV systems. Selecting suitable crops remains a complex challenge, as factors such as shading tolerance, water requirements, and economic viability vary across different geographical and climatic conditions. This study develops a novel, review-based decision support model for crop selection in Agri-PV systems, synthesizing international research and case studies to provide a structured framework for decision-making. The model is based on 12 main crop typologies and key parameters such as water use, shading adaptability, crop yield/economic potential, and space requirements, derived from 117 research articles and case studies from 25 countries. By leveraging insights from successful international implementations, the model provides a practical framework for policymakers, farmers, and energy planners to enhance the sustainability and efficiency of Agri-PV projects. Findings suggest that crop selection strategies must align with regional climate conditions and PV system design to maximize synergies between energy and food production. High-value crops that require less space and have higher shade tolerance are more suitable for small-scale or decentralized Agri-PV systems. Future research should focus on advanced modeling techniques, AI-driven optimization, and real-world pilot studies to further refine decision-making in Agri-PV deployment.

To reduce the global dependence on natural resources and pollution, many scientific efforts have been made to reduce the energy production costs from renewable sources, including efforts to exploit the inherent properties of semiconductors to generate electricity using sunlight. Solar batteries based on the first semiconductor, with efficiencies of &gt;10 %, were produced between 1950 and 1960. Currently, 80–90 % of photovoltaic components worldwide are made from silicon sheets. The use of semiconductors is revolutionizing the optical and electronics industries. Understanding the properties of semiconductors is important for understanding the activity of solar cells and improving their performance and conversion efficiencies. To generate electricity, solar cells must produce electricity and tension. Electricity is produced by motion loads, and tension requires a difference between electronic energy levels. Metal and insulation are free loads, and there is a prohibition between electronic energy levels. However, semiconductors have several advantages over metals. For a highly effective conversion, an effective load must occur, which depends on factors such as the diffusion length of the electrons and holes. The creation and recombination of electrons and their vulnerabilities are of utmost importance in solar cells. This article offers a detailed review of advanced solar sun cell technologies, new materials, loss mechanisms, and efficiency-improvement techniques. Research includes silicon materials (Si) and III-V, punishment lines of lead, durable embryos, organic photovoltaics, and solar cells that are aware of colors. In this context, promising architectural progress with graphene and super materials has been emphasized in the literature. This study also included different types of losses, including interior and external losses, in the single solar cells. Techniques to improve efficiency, such as light management and spectrum use, have been evaluated. Although the effect of solar cells based on Si is delayed by approximately 25 %, the effectiveness of multi-transition solar cells based on III-V semiconductor compounds is improved. However, mixed III–V semiconductors are subject to high material costs. In addition, indium gallium and cadmium telluride solar battery technologies can compete with crystalline solar cells owing to recent progress in cell performance. However, environmental concerns and open tensions regarding the remaining Cd are prevalent. In contrast, perovskite solar cells are highly efficient for both single and multiple arrays.

Adsorption desalination (ADS) and solar thermal humidification-dehumidification (HDH) systems are emerging as efficient, eco-friendly solutions. ADS utilizes low-grade thermal energy, operates with zero brine discharge, and has a water recovery ratio exceeding 80 %. Recent advancements in ADS include metal-organic frameworks such as composite adsorbents, which exhibit adsorption uptakes and significantly enhance performance compared to adsorbents. Raw silica gel (SG) and sodium polyacrylate (SP) are adsorbents, and SG/CaCl₂ and SP/CaCl₂ are composite adsorbent materials. Research indicates that composite adsorbents, such as SG/CaCl₂ and SP/CaCl₂, achieve the maximum specific cooling power, measured at 498.7 W/kg and 310 W/kg, respectively, compared to traditional raw or composite adsorbents in solar adsorption desalination systems. Employing raw silica gel within an ejector-integrated hybrid desalination system featuring heat recovery results in notable performance, including a gained output ratio of 2.76 and a specific daily water production (SDWP) of 83.1 m³/ton/day during June. Heat and mass recovery methods, such as pressure equalization and dual-stage evaporator-condenser configurations, have improved SDWP to ∼16 m³/ton/day and coefficient of performance (COP) to ∼0.87, reducing energy requirement. Results also reveal that with SP adsorbents, the hybrid system with heat recovery powered by solar energy (SE) and waste heat (WH) provides the cheapest desalinated water production costs (1.1 $/m³ for SE and 0.4 $/m³ for WH) among all systems. Solar thermal HDH systems are particularly effective for small-to-medium scale applications.
