I took off in Aircraft X with lighter than normal weight due to COVID...no passengers.  It was just me and about 1/3 tank of fuel.  The plane climbed much faster than I am used to.  Typically; I fly at gross with fuel and passengers.  On initial climbout I may have ever so slightly clipped ZZZ airspace.  I was with ATC; and given the 'own nav' instruction.  I took that to mean I could continue my climb.  However; that climb may have been just a little too fast.  In the future; I need to be more careful when climbing when I'm significantly below gross.
Pilot reported an airspace violation due to a fast climbing; lighter than usual aircraft.
