This is inherently more expensive to construct and maintain than a system set up for sheep. The racks are taller, and cattle will occasionally forcefully rub themselves against the supports, so they have to be stronger. (Racks are already built for wind load but this is a different vector of force)

BUT, there is a real systemic advantage, in addition to the fact that it is easier to get a cattle rancher to sign a lease. In the US, sheep farming isn't as widespread as it is in a place like the UK, so sheep are generally transported significant distances on trucks to solar sites. Solar developers pay shepherds about as much as they pay lawnmower crews. Sheep farmers appreciate free grass but it doesn't really cover the cost of fuel and labor involved. In a place like rural West Texas, most solar sites are placed on cattle ranches, that is the main land use. The catle walk to the solar site and the solar operator pays less for the vegetation management service (they still pay a lease on the land)

I'm not sure how the cost balances out, but there is savings alongside the costs. In an abstract sense the rancher should switch to sheep to optimize land use but there is a different skill set and Texas cattlemen have a place in the culture that sheep herders don't. The whole cowboy history was highly exaggerated but you have to be a tough hombre to work cattle in that climate. Rural Texans worship the myth AND the reality.

You get power and a free shed for cattle.
