Actually, a storyboard isn't just for a film with lots of cast and crew. It is also very helpful for a film with just one or two crew. It doesn't have to be a work of art, just something that you understand. It's good to be able to see your film before you start filming, then you can know what will work, and how best to make your movie (most movies/films aren't shot in the order that they appear on screen). It will add a better level of continuity throughout your shots, and can mean you wont move the camera more than necessary.
The biggest part of storyboarding to remember, is that even if it's not a work of art, it is still extremely helpful. It can literally be a quick stick figure drawing, with info on what is happening in the scene, lighting info, camera movement, shot duration, etc. on it as well. A good storyboard will save a lot of time during filming, and will also help you to concentrate on making the film the best you can, rather than trying to remember everything that is supposed to happen.

Side note, especially with stop motion animation, it feels awful to throw away a shot you have spent hours working on, only to find out it doesn't work in your film when you edit it all together. Whilst I'm not saying a storyboard will completely remove this, it will cut it back a lot. Also, some animators don't throw away their shots because they are so attached to them, and it makes an otherwise good film average.
