Too hot in Vegas most likely....panels don't like it cooking.

And lithium batteries don't like it cold. The future is sodium (and iron) batteries, I think.
For storage definitely.

Lengthy licensing processes, complex safety reviews, environmental litigation, and ever-changing regulatory requirements dramatically extend construction timelines and financing costs.
Its the regulatory burden, not the physics of generating heat from uranium, that largely makes nuclear appear expensive. Once operational, nuclear plants have relatively low fuel and operating costs and produce massive amounts of steady electricity for decades, meaning the per-unit cost of actual energy production is comparatively low.
And sure if something went drastically wrong there will be costs and issues dealing with that. But that’s the same for other energy sources. How many pensioners die each year because they can’t afford to have their heating on? This is a pro renewal ones article and it has Nuclear in between wind and solar for deaths caused.
Chart: Which power sources are most deadly? Hint — not solar and wind
Fossil fuels kill far more people than renewables and nuclear — and that's just counting deaths from air pollution and accidents, not climate disasters.www.canarymedia.com
I know someone involved in trying to clean up the mess Dounreay created. It's absolute carnage ecologically. There's all kind of horrific stuff been leaking out from the waste deposits into the sea there. Sellafield contamination has also been detected in Norwegian and Irish fish.
How dangerous though? A banana is radioactive. Everything heavier than iron is basically.

He's right. They need light, not heat.The sun is bad for the solar panels. I’ve heard it all
Temperature is not exclusive to sunlight but it is the main factor. Everything I am reading says the heat impacts the life of the panels but only slightly and far less than the increase in production. If I drive outside of Vegas there are about 20 huge solar plants.

They are genuinely trying to devise communication methods to warn the species that will inherit the earth from us about it. So 100,000s of years dangerous

There is heat and there is excessive heat

Panels work less efficiently over a certain temperature. I guess that might be different depending on the PV model but you could be looking at 25-30 % efficiency drop when they get too hot. It is not the only reason why the system may underperform. Each string works only as well as the worst panel in the string. Think of it like a blockage in a pipe. So if one panel is in the shade or faulty, it fudges up the whole string.
Solar farms or solar plants?
Why are they building solar plants in the desert?

I have no idea, you would have yo ask them....

Solar plants using mirrors works off heat, if that is what you mean.
PV needs the sun too so the desert is a good spot for them even if they don't work at optimum efficiency.
Solar Farms*
What I am reading is that they lose about 10% efficiency at 120f.
You can see here it’s still producing more in the summer months with its 100f+ most days. March & October here are similar temperatures to a hot UK summer. Can also see where I accidentally switched it off in February last year and didn’t notice for 6 months which probably cost me well over $1k lol

10% might be one end of the scale but it definitely goes higher than that.
So if I am reading your screenshot right, you are producing between 10-20kwh a day, give or take. That is a decent return and I guess you are selling back into the grid most summer months (unless you have a elec car and then maybe not).
Its half of what my rental was producing at its peak before the performances dropped of a cliff. I only have 8 newer panels on my house and there was 20 on the rental. I was getting some money back but your talking $10 a month.
