Simple version, black solar panels absorb more energy than the land around them. This results in the solar panels radiating more heat out from them.
It happens in every installation, although the temperature is most pronounced in massive solar farms that might cover thousands of acres (probably in deserts). The local temperature might be raised by as much as 10 degrees F, changing not only the local climate, but also weather patterns around the world.
I read it from here:https://www.inverse.com/science/why-turning-the-sahara-into-a-giant-solar-farm-could-damage-the-global-climate although there is plenty of data elsewhere.
Although discovered several years ago, this hasn't been talked about. I cannot imagine why.

All we have to do is run enough AC units to offset the warming.
This is so simple.

But leave the windows open when you crank the A/C. We all have to do our part.

I saw an article a few weeks back that since the lockdown, air quality was better but the average temps were on the rise. Could it be that mmgw is just bullshit? Wasn't cleaner air supposed to cool off the planet?
-
Is this heat worse than the tremendous heat generated by nuclear or conventional power plants?
Are these solar panels sucking in more solar energy than would have otherwise penetrated the atmosphere, or are they actually creating heat energy? If the latter, how are they able to create energy? That might be something worth investigating.

That right there is the AOC/GND methodology. And they say we’re a conservative echo chamber! ;D

if I recall correctly (and I'm probably wrong)... but the atmosphere retains certain frequencies of radiated energy better than others.... like UV rays getting reflected back into space. But when the UV rays are absorbed by an object which re-radiates the energy in the infrared getting absorbed by the atmosphere...
Hey, this is the interweb... I'm allowed to get details wrong. :-)

Without going back into my college textbooks, my memory says you are correct. This is why the greenhouse effect warms the planet. The atmosphere allows UV energy in, but infrared radiates up and bounces back down, and stays near the surface. The more particles due to Greenhouse effect, the more like a blanket the atmosphere acts. That's why Venus is so hot.
I think the visible spectrum is in between. Some gets back out through the atmosphere. That's why you can see the earth from the moon. So if sunlight hits bright sand of the Sahara, much more is reflected back out into space (although some remains trapped here). The darker the object, the more visible spectrum is absorbed and re-emitted as infrared ("heat").
I'm a long time away from college so I might be wrong too.
So yes, I can see where dark solar panels would do that... wow, I had no idea they were only 15% efficient. JHC that's terrible.

I get to feel heat energy when I fly over an asphalt parking lot or a recently plowed field with our beautiful black soil here in the upper Midwest.
It only makes sense the same impact comes from solar panels.

Just cover the solar panels with aluminum foil during the day to cut off the heating, and remove it at night when it's cooler.
-
Similarly, I always have wondered what consequences will arise from removing energy from the wind. There is no free lunch.

;D ;D ;D Problem solved, lol!

I have always wondered that too. It probably slows the rotation of the earth thereby lengthening our days and screwing up our circadian rhythm.

First, a typical dark asphalt roof is unlikely to absorb less insolation than a roof of solar panels.
Second, the surface area of solar farms is currently massively dwarfed by the surface area of asphalt roads. There are on the order of 2.9 million miles (4.4 billion meters) of paved road in the U.S. alone[1]. About 94% is asphalt.[2] Assuming an average width of 25 feet (7.6 meters)[3], that yields 33 billion square meters. Assuming 1000 watts/square meter of insolation at high noon, that yields 33 terawatts of absorbed power. That’s about 30 times the total electric generation capacity of the U.S. power system, which is around 1.1 terawatts.[4] Since allegedly the entire world’s average power use (including non-electric sources) is around around 16.5 terawatts of power[5] that asphalt road is looking to be a bigger climate factor than solar panels would ever be.
I once researched and compared the area used world wide by reservoirs with the amount of surface area needed by solar panels at 10% efficiency replacing all energy sources - again, IIRC, the impact was roughly similar.
Keep in mind that the entire ecosystem and weather system of the planet is solar powered - even when 30% is reflected back into space. Solar should not be dismissed with cute and technically shallow arguments.

The warming is causing the cooling. ::)

I thought they just said the cooling in Texas was caused by the warming???

Doesn't matter, so long as Oil Bad.

Cooling, warming, rain, snow, hurricanes, droughts, and tornadoes are OBVIOUSLY caused by Trump because he pulled the US out of the Paris Climate Afraud and ordered the EPA to pollute our rivers and air.

Oil and coal. Fossil fuel bad.

Which is a joke of a statement since the US was never part of the Paris agreement. Republicans Senators should challenge that as a separation of powers issue. The president cannot make an treaty and put it into law via administrative action in order to avoid the treaty approval process.
-
Republican senators are all in with the establishment class of DC, with the exception of a very few.
They didn't oppose BHO entering into an illegal treaty because they too supported it. By allowing BHO to operate with a pen and a phone, this allowed the senate RINOS to go along without putting their name on a vote, which could come back to haunt them with their constituents. This is why we are now seeing Xiden doing the same thing while the Turtle looks the other way.
Many of the Xiden EO's are unconstitutional on their face, but we've yet to see the establishment RINO's challenge them for the same reasons.

Ok, killjoy, way to ruin the joke.
But what you are saying is true. I remain unconvinced that the “Treaty on the Non-Proliferation of Nuclear Weapons” was not a treaty requiring 2/3rds of the senate to ratify, and instead was a “Joint Comprehensive Plan of Action” which didn’t have to be ratified. Obama’s unilateral agreement with Iran was a fraud.
