I'm planning to install a 20kW ground-mounted solar array and need advice on tools to help determine the right size for the concrete footings. I know I'll need to dig holes of specific depths and diameters, but I'm also considering factors like wind ratings, the square footage of the array, and tilt angles. Are there any other important considerations I should keep in mind?

I found some tools that might be useful! Check out the SkyCiv load generator for wind load calculations specific to solar panels. Also, the MT Solar's pole mount calculator could provide useful insights. And don’t forget to look into your local building codes, as they'll likely have specific requirements you need to follow.
Definitely check your local building codes; they can vary a lot! The size and setup will depend on your solar array's dimensions, wind load, soil type, and if you're in a frost-prone area. It's complex, so a thorough assessment is necessary to get it right.
I used the Iron Ridge calculator for my installation, and it was really helpful! It's free to use and provides detailed plans with drawings and a material cut list. You can find everything you need right here: [Iron Ridge Calculator](https://base.ironridge.com). It helped me figure out the specs I needed to finalize my setup!
