I believe she was 18.

In the script of the first episode it says that when Merlin walked in on Morgana that he knew she was around the same age as he was.

A boy becomes a man at age 21 in this universe. At the beginning of each episode the Great Dragon says that a young boy (Merlin) has a great destiny. At the beginning of season 4 that changes to "man". So assuming that 3 years have passed till he was 21 - we can assume that Morgana was 18 at the beginning of the series.
