With such a vague description I doubt if anyone will be able to give you much specific advice, but a very general and important starting point is to get the mechanical part working first. You will need a support structure and motor/gear arrangement that is able to point the panel in the desired directions before you can do anything else, and I suspect that this will pose some interesting problems.
There are lots of similar projects described on the web, so google something like "solar panel tracker" for ideas, or check out similar project right on this forum. Here is one How I built a sun tracker for my solar panels
PS: you will get more and more appropriate attention if you choose a sensible title for your post, like "sun tracker"
