APARICIO, Hugo; DELLICOMPAGNI, Pablo  and  CADENA, Carlos. Software for concentrating solar systems: experimental validation. Rev. ciente. UCSA [online]. 2025, vol.12, n.2, pp.22-32. ISSN 2409-8752.  https://doi.org/10.18004/ucsa/2409-8752/2025.012.02.022.

This study presents advancements in the development of simulation software for determining thermophysical parameters in solar concentration systems, focusing on thermal energy supply for heat-driven processes. The new version introduces significant improvements, including the incorporation of non-concentrated solar gain (direct incidence on the absorber) and end-losses (non-illumination losses). Additionally, a condensate factor was added to quantify non-evaporated fluid. The user interface was redesigned, changing the vertical input fields to a horizontal layout. Also, a field for equipment orientation (north/south or east/west) was included. To validate the software, extended experimental measurements were conducted over five days of energy generation using an 11 m² parabolic trough concentrator. Linear regression models were applied, and metrics such as RMSE%, MAE%, and MAPE% were used, yielding acceptable values that confirm the software's accuracy and practical applicability.

Keywords : solar concentration; numeric simulation; software; experimental validation; heat for processes.
