13 Hours for me but I was fortunate with the weather and a good instructor. I know as pilots the first solo is a major achievement but the key is not to get hung up over the number of hours or the time it is taking and to concentrate on the learning and most of all enjoying the training.
The only advice I can offer is to ensure you get the air law exam out of the way so this does not act as barrier when your instructor feels you are ready to go.
Enjoy it when it comes.......
