You don't want to use this on the roof, especially on windy area. My neighbor learned it the hard way.

For this tracker, you need a battery. An old motorcycle battery worked for me, but you need another small panel with charge controller to keep it charged. Something like a 20W panel is fine, though if you get snow in the winter, you'll need to keep it cleared.
I have not found standard panels that fit the dimensions of this array. The Eco-Flow panels are an odd size, so see if you can find better panels before you buy this tracker. Also, there is a windspeed limitation. The included anemometer tells the controller when to go horizontal due to wind speed, but there's also a max wind speed where the instructions say you have to remove the panels. That's pretty impractical. In practice, mine went rhough some decent winds last winter with no problems. It rocks a lot, but no structural issues. There are lots of trees around, so wind speeds are moderated in my yard.
I bolted it with 8" or 10" lag bolts to a solid (not rotted) spruce tree stump to test it out. Not expecting that to last more than another year or two. You're supposed to sink some concrete footings to secure these things permanently.
