Photovoltaic (PV) panels play a pivotal role in advancing renewable energy adoption by offering clean and sustainable alternative to fossil fuels. However, elevated operating temperatures diminish PV cell performance, reducing output accelerating material wear. This research evaluates the cooling efficiency of panel equipped with three‐dimensional oscillating heat pipe (3D‐OHP) integrated hybrid nanofluids consisting graphene oxide–copper oxide (GO–CuO), carbon nanotube–CuO (CNT–CuO), multiwalled CNT–CuO (MWCNT–CuO). The OHP is charged two concentrations each nanofluid, specifically 0.1 0.2 g/L, evaluate their impact on thermal management panel. study involved experimental tests using panels: one 3D‐OHP as cooled other reference under identical environmental conditions. Hybrid were prepared dispersing nanoparticles base fluid, properties characterized prior use. Energy exergy analyses quantify enhancements reduction entropy generation. Experimental results reveal that concentration g/L remarkably improves electrical power 12.07%, outperforming studied systems maximum 31.2%. findings also highlight notable gains first‐law efficiency. Furthermore, levelized cost (LCOE) storage (LCOS) are analyzed, demonstrating economic feasibility nanofluid‐based for systems.
