Hey Lawrence,
Absolutely. Generally speaking, ground mount installations are a lot easier and safer than roof mount installs. But you need to trench and put cable/conduit from the panels to your house which can be labor intensive and possibly expensive.
Here are a few reddit threads discussing it:

The Install Guide on the Solar Circle website is for roof installs, so I can't speak on specifics for ground mount installs, but the basic idea is the same. Check out https://diysolarforum.com/ and you'll likely find some documentation on ground mount installs (although a lot of folks on the forum are off-grid installs with batteries, which is quite different from a grid-tie install.
