The student pilot reported that during a solo flight he was performing takeoffs and full stop landings in the traffic pattern. During the landing roll, he configured the flaps to zero and applied full power. The airplane pulled to the left and he overcompensated the right rudder pedal application. "In an immediate reaction to reverse this I applied left rudder to quickly and went immediately to far left causing a fishtailing effect." The airplane exited the runway to the left and struck runway signage and a fence. The airplane sustained substantial damage to the left wing, the landing gear attachment points, the horizontal stabilizer and the elevator.
The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
