However, the adoption of BIPV in India remains limited due to factors such as regulatory barriers, lack of standardized designs, and high initial costs. This study uses SWOT (Strengths, Weaknesses, Opportunities, Threats) and TOWS (Threats, Opportunities, Weaknesses, Strengths) analyses to assess the potential, opportunities, and challenges of BIPV in India’s urban planning.

Key findings of this study indicate that BIPV adoption in India can significantly contribute to urban sustainability by reducing carbon emissions, improving energy self-sufficiency, and lowering long-term operational costs. The SWOT and TOWS analysis reveal that while BIPV presents opportunities for smart urban integration, challenges such as high initial investments and lack of awareness must be addressed through targeted policies and incentives.

However, large-scale PV deployment faces key challenges such as high land acquisition costs, elevated panel temperatures, and dust accumulation, all of which can hinder economic viability and energy efficiency. In response, two innovative concept: Floatovoltaics (FPV) and Agrivoltaics (APV) are gaining global traction as integrated solutions to these limitations. FPV systems are installed on water bodies such as reservoirs, lakes, and canals, where the surrounding water provides a natural cooling effect, enhancing panel efficiency and reducing thermal stress. They also contribute to reduced water evaporation and minimal land use. Conversely, APV systems combine agricultural activity with solar energy generation on the same plot of land. This dual-use approach not only improves land-use efficiency but can also create a cooler microclimate that benefits crop productivity. Both systems also exhibit significantly lower soiling rates compared to conventional ground-mounted PV.</div><div>This review presents a comprehensive analysis of FPV and APV technologies, with a specific focus on their potential deployment in India, a country with an estimated solar potential of 748 GWp and mounting pressures on land and food systems.

Among all alternative cooling technologies, the liquid desiccant system (LDS) has gained attention as an energy-efficient and sustainable solution offering precise humidity control. The performance of LDS is strongly influenced by the desiccant type, with desiccant blends demonstrating superior moisture absorption compared to single desiccants. Among these, a blend of lithium chloride (LiCl) and potassium formate (KCOOH) shows promising dehumidification performance with reduced corrosion potential, yet remains underexplored. This study investigates the optimal blend ratio of LiCl-KCOOH through experimental analysis within a hybrid liquid desiccant vapour compression (LDVC) system. The research compares the dehumidification performance of this blend against a pure LiCl solution, employing an optimal mixture design technique to develop empirical correlations for key performance parameters.

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 $/m³ for WH) among all systems. Solar thermal HDH systems are particularly effective for small-to-medium scale applications. Packing materials such as polypropylene and porous plastic balls in humidifiers and fin-tube heat exchangers in dehumidifiers enhances performance. Solar water heaters outperform air heaters due to water’s higher specific heat capacity, with optimized operating conditions achieving maximum efficiency. The freshwater production cost for a hybrid system (ADS+HDH based) using solar energy ranges between 1.4 and 2.24 ($/m³). This study integrates numerical insights from ADS and HDH systems, highlighting advancements in SDWP, COP, and cost efficiency. Future research should optimize adsorbent designs, reduce heat and mass transfer resistances, and develop low-regeneration temperature materials for sustainable and cost-effective freshwater production.</div></div>","PeriodicalId":101173,"journal":{"name":"Solar Compass","volume":"15 ","pages":"Article 100125"},"PeriodicalIF":0.0,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144178002","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}
