Great. Here is an example regulator that will take 30-60V input and output up to 10A at 12V. You could run quite a bit on that. If your panel is vertical, but in direct sun through a window, you should be able to produce typically about half that current and run a 60W device. Alternatively, you could put in a small battery and a charge controller to power something interactive that takes more power.
