I believe that, while a cool technological innovation, the cost of installing and maintaining these panels will be significantly higher than doing the same on open land.
The article’s biggest claim is that devoting one percent of US farmland to agrivoltaics could cover 20 percent of the country’s electricity, pointing at the Texas to Nebraska to California corridor, which is exactly where big mechanized farms are most common.
They run large equipment (combines, sprayer booms, center pivot irrigation systems[1], etc). To keep that working under panels you need tall posts, wide spans, and a layout that matches the equipment paths, which would push structural cost significantly above a ground installation. All maintenance would require a boom truck, not just a ground crew. And center pivots in particular (very common) need an entire circle cleared for the system to pivot, meaning a multi-acre span with no posts for the pivot to hit, which is simply infeasible.
That’s before accounting for pesticide spray and dust on the PVs, or the logistical burden of running PV crews through a working farm.
It’s also worth noting that the study itself was broccoli, which is hand harvested and about the best case crop for this. Even so, the broccoli took 25 extra days to mature. On a farm running multiple rotations a season that lost time has a real cost, separate from the structural costs.
This innovation has a lot more promise on smaller plots. Co-ops, market gardens, specialty crops, and the like that don’t rely on large equipment. I’d be surprised to ever see it on a large farm.
Maybe today but with the rise of automation, who knows?
