Motivated by the aforementioned research, the objective was to develop a PV model of clear sky correlations at different surface elevation measurement stations at the measurement scale. However, the theoretical model was used to determine the solar energy analysis. Initially, the solar energy sample collected in about 16 locations across Mozambique was processed using time intervals of 1, 10, 15 min, and 1 hour. Then, the clear sky radiation was found, and the clear sky index (<span><math><msubsup><mi>K</mi><mi>t</mi><mo>*</mo></msubsup></math></span>) was calculated. Other data were collected using PVGIS, NOAA, and Meteonorm data from 2004 to 2024.

Four identical units, constructed with galvanized iron basins, internal matte black coating, thirty millimeters of polyurethane insulation, and four-millimeter-thick clear float glass, were tested simultaneously with a constant basin water depth of two centimeters.

Conventional cooling systems often overuse water, consume high auxiliary energy, or lack automation, limiting scalability. To overcome this, an automated hybrid system combining passive fins, active water flow, and ultrasonic humidification was developed and tested. The system features a microcontroller-based control unit that triggers staged cooling responses at defined temperature thresholds, minimizing operational resource input. Field trials were conducted under real outdoor conditions in Rajshahi, Bangladesh. The experimental results revealed average panel temperature reductions of 8°C, with peak reductions reaching 13 °C. Electrical conversion efficiency improved from 13.35% to 15.60%, corresponding to a 16.85 % relative gain, while power output increased by 15.9%. The system achieved a net daily energy gain of 0.0469 kWh with minimal auxiliary load (0.0075 kWh/day), and water consumption was limited to 40 L/day. The techno-economic assessment yielded a levelized cost of electricity of 0.052 USD/kWh for the cooled system. The analysis further indicated a payback period of roughly 18 years for the cooling investment, with a corresponding net additional energy yield of 357.7 kWh over the system's operational life.

Additional measures like heating electrification, storage, flexibility, and local energy management are needed. While most studies either focus on individual case studies or aggregate the national energy system into a single entity, this work combines municipality-level resolution with a nationwide assessment. Using an hourly multi-energy system model, we simulate the energy systems of 2131 Swiss municipalities to assess the impact of solar PV expansion with and without complementary measures. Alongside PV expansion, we study the effects of replacing 50% of fossil-based heating with heat pumps (HP) and implementing thermal energy storage (TES) sized up to 20% of annual heat demand. At the national scale, emissions decrease by 40%, and the renewable share increases from 43% to 66%. The largest improvements result from replacing fossil heaters with HPs, which lower emissions and absorb additional PV generation. TES further increases renewable utilization by shifting HP demand to periods of high PV yield. At the municipal scale, the impact of each measure depends strongly on existing PV capacity and demand profiles. In municipalities with high PV implementation, HP and TES deliver larger benefits than further PV expansion alone. The findings show that PV expansion must be combined with system integration measures to achieve substantial emission reductions and higher renewable supply.</div></div>","PeriodicalId":101174,"journal":{"name":"Solar Energy Advances","volume":"6 ","pages":"Article 100135"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147656561","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}
