Her last name will probably never be properly revealed. I think in one episode - most likely a season finale or perhaps even series finale - someone (or perhaps she herself) will refer to her as "Penny Hofstadter" or even "Mrs.  Hofstadter".

If we ever learn her maiden name it will probably be Wyatt because, as someone else has pointed out, she referred to her father as Bob in the first episode we met Leonard's mother and when Leonard met her father in a later season he called him Wyatt. I can't imagine someone being called Bob Wyatt without Wyatt being the surname. Bob Wyatt and then something more is a bit much for my taste.
