Abstract

This paper represents the comparison and the validation of results obtained from the simulation, towards the measurements performed in a forced-circulation solar water heating system equipped with flat-plate solar collectors. Polysun tool is used to model and to simulate the considered system during an annual time period. Mathematical models are used to calculate the required sensible heat, thermal yield from the flat-plate collector area, delivered energy to the thermal consumer, efficiency of the collector area, efficiency of the system, and the solar fraction. To validate the model, experimental data recorded in time intervals of 5-minutes in a trial installation are utilized. Statistical test errors (epsilon, MBE, MPE, RMSE, and R^2) are used to compare the values obtained from the simulation and measurements. Between them, a very good fit is noticed.
