@ariaflame @titia @M0YNG @WiteWulf @stux but not goats.
Apparently trials prove the obvious that they climb on the panels and break them
@Tattie @roastinghouse @ariaflame @titia @M0YNG @stux flexible elastic PV panels: solar trampolines for goats
You know it makes sense 😆

This is apparently true.
I've also read (no reference) that wool yields from sheep grazed underneath went up?
@bytebro @M0YNG @WiteWulf @stux It's worth pointing out that a great many fields are artificial carveouts from other sorts of biome, like forest or grassland. In some cases, building elevated solar panels returns a measure of shade that was lost when farmers clearcut the area.
But yes, by all means, but them over car parks, too.
@bytebro Yep, source for the improved quality wool is https://lightsourcebp.com/nz/news/wool-quality-and-sustainability-insights-from-lightsource-bps-wellington-solar-farm/
(Source is an interested party but still, it does seem plausible that sheep who can hang out under shelter when they want will be less stressed than those exposed constantly to the elements.)
Agrivoltaics seems to be a win for the plants, for the animals, and for the panel efficiency and output.
As for the carparks, how about we get proper public transport, then we can turn most of the carpark into parklands (while leaving just enough space for accessibility and deliveries and emergencies) and that will also be a win for everyone. ;-)
@WiteWulf @stux This article from "Spektrum der Wissenschaft" explains quite a lot regarding the synergy and problems of growing both crops and energy. Unfortunately, its behind a paywall and in German.

But is the farmer making enough money to live on with those grass and animals?
Reliant on variable (and increasing extreme) weather, market prices, export prices, tarrifs etc.
It might look pretty, but it might not be economical worthwhile.
Using part of his land for solar lets the farmer have an guaranteed income through droughts etc.
You can also grow some crops better under solar. Sheep who graze under solar prduce better wool.
@WiteWulf
Switzerland is trying.
Am 24. April 2025 hat Sun-Ways das weltweit erste für den Bahnverkehr freigegebene zwischen Bahnschienen verlegte Photovoltaik-Kraftwerk eingeweiht. Bei eher trübem Wetter hat Sun-Ways seine erste Solaranlage in den Neuenburger Bergen
What reasons wouldthat be?
The reason they're doing it is because Switzerland has >5000km rails. And since Switzerland is not very big, they intend to use every dead space they can. That's why they're doing a field test, see how it goes. And it's not that you could use the space for anything else.
Roads are not a great place for solar.
A) get shades by cars.
B) get dirty
C) don't last
D) slippery to drive on.
Between rail lines also not a great idea.
A) get shades by trains.
B) get dirty, from train brake dust. Have a look under a train, it gets covered in dust.
C) need custom size panels, custom fixtures.
D) needs to be moved to check and maintain sleepers, ballast, tracks.
E) impact damage
D) comes loose or tampered with and can cause serious derailment
F) needs special cleaning train.
G)low energy density.
In both cases building a standard frame on the side of the road/ rail corridor, or building on station roofs, or on the many empty roofs would be a lot cheaper and generate more electricity.
But these practical but boring things dont, don't get your company PR/clicks
@stux There's some rudimentary info here on why it's actually a good idea: https://science.howstuffworks.com/environmental/green-science/agrivoltaics-solar-panels-agriculture.htm
Also, we can have solar panels on BOTH fields and car parks!
@stux Both is better!
But I understand that here in Louisiana, it's impossible. You see, if we covered our car parks then the cars we're forced to use wouldn't get steaming hot under the summer sun.
Sorry, it's very important that we make everyone extremely miserable for no reason. It's extremely important that we don't provide any shade to parked cars here in hot miserable Louisiana.
We also got rid of window awnings. That was very important also.
As panels are getting cheap, the support structure becomes a serious part of the cost (and even of the embedded energy). You need a lot more steel and foundations for such elevated panels.
Not sure about now, but not too long ago parking lots were money-losing PR projects(look us being green), while the field ones were serious.
Once we have enough PV to saturate summer peaks, every next panel produces less useful power. So lower cost is critical
Yes, but that costs serious money as well. Cheaper PV means more installed PV for the same money, means more hours that you can run mostly on the sun before you need batteries or other costly alternatives and complications.
That's why I am nervous about anything that drives up cost. We have not yet fixed that climate thing, and it becomess harder as the low hanging fruit gets done.
(there are some plants that, in some parts of the world, have been shown to grow better in the partial shade provided by solar panels than they would in the full sun)
(I suspect that they would be a bit higher up than they seem to be in the first image)
Rooftop solar, on just HALF of the world's roofs, would produce MORE electricity than is used today from ALL sources. And would uplift all people, strengthen all people, and drive a permanent economic boom.
Let every Neighbourhood become Saudi Arabia, but free.
This 2009 article contained my “go-to" infographic for many years:
https://landartgenerator.org/blagi/archives/127
It's since been updated:
https://landartgenerator.org/blagi/archives/77565
IMHO the former though contains some more "appealing" observations, e.g.
"The Saharan Desert is … 18 times the total required area to fuel the world”
"if the efficiency of conversion from solar to electricity was 100%, the area of USA highway would be equal to exactly that required to run the world”
And repair the accounting error that created the direct cause, the financial aneurysms of accumulated cash, billionaires. Ready to stroke out the civilisation. Billionairism.
Goos tax laws that help everyone become multimillionaires. Everyone.
@stux Solar panels on fields can be very beneficial for the vegetation.
You can even generate energy on 3 levels above the field (huge windmills, smaller windmills, solar panels) while saving water because the plants have more shade.
Parking lots on the other hand shouldn't exist at all.
