Well done mate. It's an achievement and shows you've got a natural ability to handle an aircraft.
But as CAT3C AUTOLAND points out, if you've been taught according to the JAR syllabus you'll have done a minimum of 13 lessons and these ought to take an hour each. If they haven't, I would question the thoroughness of the training.
No matter how good the student, my FTO wouldn't have allowed solos below 13 hours.
IMHO there's simply no point rushing through the PPL, especially in the early days when you're learning new techniques on each flight which will underpin your future flying skills. My PPL instructor only had to show me each skill once because I picked it up quickly, but I was then encouraged to consolidate the skill before moving on.
Seeing as most people who start out to get a PPL eventually go solo and get their licence, the basics can't be that difficult. But as you get more into the aviation world you'll see plenty of people with a couple of hundred hours who get up in the air and back down again without crashing, but you wouldn't call them good or even safe pilots. They're probably more confident in their abilities than they ought to be. IMHO it's preferable to be self-critical of your flying abilities and modest. It makes you question yourself and constantly improve.
So what I'm saying, in the nicest possible way, is that piloting is not an ego trip and it's not about breaking records or doing things in quick time. It's about being safe and flying safely, properly and improving each time you go up.
Going solo early is a great start, but use the extra time you've got in your training to consolidate!
