Haven't read the full article (paywall), but the biggest issue with co-mingling livestock and solar panels is the damage they cause to the installation by chewing through or rubbing up against insulated wires.<p>Also, when the panels are at full extent first thing in the morning (e.g. almost vertical facing east), it's very easy for animals to come in contact with the panels themselves.<p>The corollary to this (at least in Australia) is that most solar farms are being installed on (now) vacant grazing land where 150+ years of cultivation has meant that the grasses that grow on them are very fast growing and hardy.<p>Mowing the fields beneath the panels is a full time job just to reduce the fire hazard.
...and sheep are good for preventing forests from regrowing in the UK and the Republic of Ireland? (for one regional example)<p>And sure, wool and mutton too, but the level of environmental destruction wrought by humans via sheep is baaaad.
