Here, the statistical features of a proxy of the local entropy production rate, in solar quiet regions at different timescales, are investigated and compared with the symmetry conjecture of the steady-state fluctuation theorem by Gallavotti and Cohen. Our results show that solar turbulent convection satisfies the symmetries predicted by the fluctuation relation of the Gallavotti and Cohen theorem at a local level.ELETTRONICOenArticle10.3390/E220707162-s2.0-85088311430https://api.elsevier.com/content/abstract/scopus_id/85088311430https://www.mdpi.com/1099-4300/22/7/716FIS/05 - ASTRONOMIA E ASTROFISICA
