Fusion in the Sun’s core releases neutrinos and high-energy photons together: a neutrino can reach the surface in about two seconds, while the photons’ energy may take roughly 170,000 years to escape after countless scatterings, absorptions and re-emissio - Space Daily

Solar neutrinos escape from the core in seconds, while radiant energy diffuses through dense plasma for roughly 170,000 years before it can leave as sunlight.
