Narrative:

This was an incident where we lost several panels during flight. We had no indication of when the panels came off. The aircraft had gone through maintenance the day before due to the aircraft not producing heat to the passengers or pilots. The following day the aircraft was working good and putting out heat; making the flights that day tolerable. My first officer made the preflight for the day but saw nothing unusual in the walk around. We were originally scheduled to fly one more leg but due to the time and the condition of the airport; both runway and ramp had areas of ice; making taxiing and possible takeoff unsafe. I informed my company that we needed to end the trip there and go to the hotel. The next day when we reported to the airport is when we discovered that the aircraft was missing the panels.
