Will it be necessary to replace the panel in a medium future ?
I'd say it's much more likely to be a piece of space debris which surely does not have such a relative velocity...but meteoroids are traveling through space at speeds of well over 25,000 mph — many times faster than any bullet!

However, experts believe the hole was probably caused by a random object, possibly space junk, which would not have been able to penetrate the layers of the station's hull.
Jim Scotti, a planetary scientist at the University of Arizona's Lunar and Planetary Laboratory, said: “It's unlikely this was caused by a meteor, more likely a piece of man-made space debris in low Earth orbit.”
Oops......that's the same place that the astronauts tried to stop ammonia leaking by deploying another radiator last November in an EVA, so apparently that's NOT the culprit! :blink:
Note that this very probably will mean that power channel (2B) will need to be shutdown, taking down one-eighth of the station's power supply. An emergency EVA to replace the pump is not out of the question.
Ammonia Leak Outside Station; Crew in No Danger05.09.13
At around 10:30 a.m. CDT on Thursday, the Expedition 35 crew reported seeing small white flakes floating away from an area of the International Space Station’s P6 truss structure. The crew used handheld cameras and Mission Control used external television cameras to gain additional imagery in an attempt to narrow down the leak’s location.
The crew reports, along with imagery and data received by flight controllers in Mission Control in Houston, confirmed that the rate of the ammonia leaking from this section of the cooling system has increased. Ammonia is used to cool the station’s power channels that provide electricity to station systems. Each solar array has its own independent cooling loop. This ammonia loop is the same one that spacewalkers attempted to troubleshoot a leak on during a spacewalk on Nov. 1, 2012. It is not yet known whether this increased ammonia flow is from the same leak, which at the time, was not visible.
The station continues to operate normally otherwise and the crew is in no danger.
Plans are being developed to reroute other power channels to maintain full operation of those and other systems normally controlled by the solar array that is cooled by this loop.
The early analysis by thermal control systems specialists indicates that the leak rate could result in a shutdown of this one cooling loop in about 48 hours. The team is looking at whether any additional imagery is needed to isolate the leak’s location.
I hadn't seen this posted until today. Something a little different from Chris Hadfield.
