The heat-absorbing and heat-releasing properties of phase-change materials (PCMs) at specific temperatures make them ideal for improving the thermal management solar systems. Thermal conductivity PCMs is increased when combined with nanoparticles, leading to significant improvements their ability manage transfer heat efficiently. objective this article anticipate liquid fraction (LF) a suitable level accuracy by utilizing machine learning predictive models in building-integrated photovoltaic (PV) system. Four different system configurations were proposed, namely PCM without fins, longitudinal additional nanomaterials Y-shaped fins. After accomplishing numerical simulation data, order save computational cost maintain accurate predictions, following chosen accomplish objective: linear regression, lasso polynomial an Auto-Regressive Integrated Moving Average (ARIMA) model. Then, comparison all cases, using root mean squared error (RMSE), as well absolute (MAE). ARIMA model had superior performance predicting LF, achieving RMSE 0.0149 MAE 0.0093. This technique has been used predict LF other situations. results indicated that case incorporating inclusion nanoparticles fins exhibited shortest time required reach value 1. approach study reduces reliability on computationally expensive simulations, which provides more efficient method optimizing PV also highlights potential enhance cells, contributing sustainable energy solutions.
