Goats are definitely off, I found they ate everything except what you
wanted them to. Very cute though. The low profile "Robo mower" idea
has merit.
The best I've seen was a wild flower seed mix, that all grew only a
couple of feet high max. They probably needed some weed wacking a few
times a year, but much less than grass. Totally depends on the
location. On the wet side of Maui, you would have the array disappear
into the jungle in 6 months, never to be seen again. In the desert, it
might be sage brush after 10 years.
I worked on a project once that used 4" deep gravel spread over 160
acres. Total disaster in my opinion; think how many cubic yards had to
be trucked in. Vehicles got stuck in the loose gravel, it slowed
everyone down, and 3 ft high weeds were growing up out of it in 6
weeks. Then when you went to weed wack, you had gravel projectiles sent
flying into the glass.

Goats can be tough as they like to eat wire and climb on the panels. But if the
modules are off the ground high enough might work.

This is not so much a "wrench" question--more like a "lawnmower" question...
For anyone involved with large-scale ground mount systems, I am curious about the
various methods being used to control vegetation. My sense has been that O&M
service providers generally gravitate toward gas mowers/trimmers with spot
application of chemical herbicides. Does anyone have any experience with
alternative methods, such as specialized seeding (e.g. pollinator-friendly),
groundcover plants, goat herds, maybe even robotic GPS-guided mowers? I'm
especially interested to hear from anyone who has analyzed the pros/cons of
different methods or who can speak to any approaches that might be site-specific.
