20.500.12556/DKUM-95593 Dynamic modeling and experimental validation of the photovoltaic/thermal system The aim of this paper is to present a novel and comprehensive methodology for the dynamic modeling and experimental validation of a photovoltaic/thermal system. The dynamic model is divided into thermal and electrical subsystems, encompassing the photovoltaic/ thermal module and the thermal energy storage. The thermal subsystem of both the photovoltaic/thermal module and the thermal energy storage is described by a one-dimensional dynamic model of heat transfer mechanisms and optical losses, while the electrical subsystem is presented as an electrical equivalent circuit of double diode solar cell. Model validation was conducted on a modern experimental photovoltaic/thermal system over an extended operational period at a five-minute resolution, with validation days classified as sunny, cloudy, or overcast based on weather conditions, thereby demonstrating an applied approach. The results demonstrate the lowest deviation values reported to date, confirmed using six quantitative indicators. The added value of the proposed methodology, not previously addressed in the literature, lies in the following contributions: (i) comprehensive modeling of the entire photovoltaic/thermal system, (ii) accurate consideration of optical losses in the photovoltaic/thermal module, and (iii) long-term experimental validation. Overall, the proposed methodology provides a reliable and efficient framework for PV/T system design, optimization, and long-term performance assessment. photovoltaic/thermal system thermal energy storage dynamic modeling experimental validation heat transfer mechanism temperature electrical power sončna energija fotovoltaika zaloga toplote fotovoltaični/termični sistem shranjevanje toplotne energije dinamično modeliranje eksperimentalna validacija mehanizem prenosa toplote temperatura električna moč true false true MDPI Angleški jezik Slovenski jezik Znanstveno delo 2025-09-30 03:33:32 2025-11-10 09:49:37 2025-11-11 03:08:47 0000-00-00 00:00:00 2025 0 0 Str. 1-32 št. 19, št. članka 10505 Letn. 15 28. 9. 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2025-08-29 2025-09-25 2025-09-28 620.91 250780675 10.3390/app151910505 2076-3417 Sredensek_2025_Dynamic_Modeling_and_Experimental_Validation.pdf Sredensek_2025_Dynamic_Modeling_and_Experimental_Validation.pdf 1 E4C9E21E0FCCE9CCFF055AC042A31043 8d8529f6ccd61c4d0114998022acf870ee29608f9ad2adab64aca31b0c684705 d34a3db8-be11-11f0-8bb8-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=200505 https://doi.org/10.3390/app151910505 0 7a335a5c-9d9d-11f0-99e2-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=199372 Fakulteta za energetiko Fakulteta za elektrotehniko, računalništvo in informatiko 0 0 0
