The utilization of ANN demonstrates their efficiency and stability for maximum power point tracking (MPPT) against varying irradiation and temperature.

That indicates that both algorithms can track effectively the maximum power point but the FC technique tracks more, despite varying weather conditions especially variable irradiation. Similarly, subject to stable irradiation and varying temperature scenarios, the FC technique verifies a MAPE of 2.18%, also lower than that of the ANN of 2.67%.

Unlike conventional models that primarily address either economic or operational aspects, the proposed approach offers a comprehensive optimization framework that simultaneously considers energy generation, storage management, and grid interaction.

Computational experiments reveal that GMOA consistently outperforms GWO, achieving lower total costs, higher renewable energy utilization, and improved computational efficiency.

Using solar energy to dry these food products is a promising approach that does not compromise their nutritional value. Despite significant advances in solar energy drying systems, the adoption of solar drying remains limited due to low energy efficiency, inconsistent performance under varying weather conditions, and the absence of scalable design frameworks.
