Purpose This study aims to investigate the thermal performance enhancements of phase change materials (PCMs) through integration extended fins and CuO nanoparticles under impact solar irradiation. The research focuses on improving melting behavior efficiency PCM-based energy storage systems facilitate design more efficient solutions. Design/methodology/approach analysis is conducted a top-heated rectangular system filled with pure PCM nanoparticle-enhanced (NePCM) mixed 0.01% Wt. nanoparticles, varying fin configurations considering volume surface area constraint. shape modified from single multiple numbers, maintaining same area. carried out both experimentally numerically for without case, (utilizing finite method) different sizes positions fins. evaluates nanoparticle inclusion, geometry variations three types (lauric acid, RT-35HC P-58). Numerical results are validated against in-house experimental results. Findings successfully validates numerical simulations data, enhancing credibility findings real-world applications. addition resulted in 16.36% enhancement storage, as observed experimentally, whereas simulation showed an 8.55% increase. inclusion accelerated process across all configurations, notable parameter 16.51% arrangement. introduction structure increased rate, but further additions led diminishing returns, maximum rate 35.19 J/min achieved CuO-enhanced presence fin. also highlights most effective PCM, offering highest fastest speed, making it ideal rapid response Research limitations/implications Future could explore concentrations well broader range geometries enhance systems. Long-term validation conditions would applicability reliability findings. Originality/value provides valuable insights into optimizing by combining optimization. offer practical guidance effectiveness units various
