I had looked into this idea a couple years ago. There are so many ways you can go with it though. It can get to be a rabbit hole if you're not careful, you almost have to watch all the different ways, and kind of balance out the factors important to you (between turn-key solution vs DIY, electric or mechanical, single-axis vs dual-axis, tracking control mechanism or electronics), decide on the methodology you want to use.
I never did do anything with it, but just had pondered on all the different stuff involved. I'll just post a couple links from bookmarks I had thought were interesting to me at the time:

There's even more options and videos too now when I do a current search on it:
I would just watch as many videos as you can on it before deciding on a particular way yet.
Wind factor would be a big concern to me, depending on your area, making sure whatever you design is strong enough. I'd almost rather build a single-axis tracker (single-axis still will follow a correct arc on the azimuth angle, and can track the sun fine), using a separate manual up-down seasonal-adjust (similar to the old C-band satellite dish antennas), because the dual-axis right on the pivot, they seem to be too weak, unless you use really heavy-duty parts. I liked the chain drive method above where it pulls farther out from the sides, instead of so close to the pivot, seem stronger.
Also, to keep some spacing between the solar panels to let excess wind pressure bleed off and go through the array (reducing 'sail' effect).
