Thermal energy storage, particularly through Phase Change Materials (PCMs), is gaining significant attention for its ability to enhance storage capacity and thermal conductivity. PCMs help alleviate the strain on renewable sources stabilize load fluctuations. This study integrates a novel combination of LiNO3-NaSO4·10H2O-NaCl with boron nitride into Flat Plate Collectors (FPCs) boost system performance. Composite Material (CPCM) increases latent heat value by up 245.80 kJ, enhancing decomposition absorption rates while reducing losses. Boron improves conductivity 25%, from 1.378 W/m·K 5.543 W/m·K, increasing CPCM's charging rate. The specific rises 4.2 J/g·°C 5 at maximum temperature 90°C. As result, collector's efficiency 15%, achieving an overall 88%. Water serves as transfer fluid, simulations are conducted using Python in Anaconda Jupyter Notebook.
