The Fermi-Large Area Telescope (LAT) observations of the flaring Sun over the 24th solar cycle have revealed an extremely rich and diverse sample of events, spanning from short impulsive-prompt flares to the gradual-delayed long-duration phases increasing the total number greater than 30 MeV detected solar flares by almost a factor of 10. Some of the most significant cases are the March 7, 2012 flare whose greater than 100 MeV emission lasted for more than 20 hours and the September 1, 2014 behind-the-limb flare with GeV emission lasting for more than 2 hours. In this hyperwall talk we will present some of the highlight results on high-energy solar flares seen by Fermi-LAT over its first 13 years of orbit.
