Different clubs have different standards for soloing. Ours happens to require quite a bit more than yours.

During my solo flight my instructor sat in a chair about 30 feet away and watched. I had to take off, fly an oval pattern in each direction while maintaining altitude, then the same with a figure eight. I had to do both a left hand roll and a right hand, and a loop while traveling in each direction. I then had to do a stall turn, and finally show that I could fly a good landing pattern and land.

To me, soloing is something more than just getting the plane off the ground and back down again, but there are no "rules" about what constitutes a solo flight.
