Plants love sun, why would I put them below a panel into shade. Article mentions blueberries which I grow and those which get the sunshine only half of the day (partly in shade) don't have the same sweet taste as other in better sunny spots of my garden.

> Plants love sun

No. Some plants love direct sunshine and others don't.

They do love sun, but they might not like intense heat.

Take those blueberries, Mine hate being in certain parts of the patio because whilst they get full sun, they also get longer and more extreme levels of heat. I almost lost them the year before last.

(this is with a decent irrigation system too)

You can get bifacial panels that let light filter through. Not sure what is filtered, but perhaps the remainder is sufficient for certain crops?

Here is a chart of DLI (daily light integral) needed for lots of common crops.

Here is a map of DLI in the USA by month.

So there is some wiggle room maybe. Looks like about 30 is good DLI and the USA gets 40-60 in the summer.

My gut feeling though tells me that the best performance is panels that use all the light or plants that get full access to it.

I would assume that the biggest factor in this would be that the racks and solar panels make it very difficult to use large machinery such as tractors and harvesting machines? Somehow this isn't even addressed.

Farm machinery got "big" because it enables one human to be more productive, cover more area in one unit of time. Human time is one of the most expensive resources in farming.

As we automate more farming, and move to self operated machinery, we can shrink those machines down again. We can design fleets of machines to work in tandem, and operate around other structures, such as solar. The age of the tram lines is going to come to an end.

This also provides opportunities for replacing chemicals with small robots, such as for weeding.

One of the incentives the article doesn't mention is property tax. Where I live, agricultural land is taxed much less than other property. The moment you put solar on your meadow you pay the regular rate. I think it would be fair if property kept its agricultural tax status if it is used in an environmentally friendly way.

Human or AI generated, it's clearly SEO optimized. I think that's the real problem.

Or maybe use illegal cheap labour from another country. Something like feudalism, but more modern!

Really I blame Google for this, obviously any online publication needs to optimise for traffic, they need to pay the bills. But Google's latest algorithm changes quite clearly prioritise longer prose, and so bulking out text in articles has become the norm. It's a shame, and Google have the resources to do better, but unfortunately not the incentives. Most of the pages have some amount of Google ads on them.

You joke, but there are a lot of crops that can't easily be machine picked, and probably never will be. Although I'm a proponent for legal safe immigration for sessional work with a route to permanent residency. The lack of legal routes results in unsafe working conditions and modern slavery.

PVs are always raised off the ground.

This is not some new invention, people just planted some stuff under the PVs.

You can also get some goats to clean the weeds in the place before that. They will appreciate the shaded area (but hopefully not the cables)
