Lots of details, but this one is the kicker:

It wasnt until panels started going up next door that Inder saw a surprising opportunity. He could see that green grass was growing under the panels every time it rained, and there was none on his side of the fence.
I had a had a beer down at the local pub with the site manager at the time, and he was explaining to me that they were looking at mowing the [solar farm] six times a year at a cost of $90,000 per mow.
That beer turned into a collaboration. Inder suggested using sheep to manage the grass under the panels instead of expensive mowing.
Today, Inder grazes around 2,000 merino sheep across two solar farms, where the sheep get constant shade and shelter, and the solar operator has slashed mowing costs to a single pass per year.
The only drawback to solar sheep grazing? Mustering can take longer because the sheep dont want to come out of the shade.
