I'm not a solar panel expert, but I thought the purpose of a solar panel was to capture and absorb the energy from the sun and to convert it into electrical energy. So, your fear seems to be the opposite of what really occurs.

Whether the energy from the sun is absorbed into the earth or reflected upwards, the total amount of heat energy doesn't change.

The loss of ice cover at the Poles is speeding climate change as the white surface reflects a lot of the Sun's energy straight back into space. Anything that reflects this energy will help slow climate change, and the nearer that surface is to the Tropics the more beneficial the effect will be (as there is a lot more of the Sun's energy per square foot at the Tropics than at the Poles).

Solar panels have also been shown to be beneficial on farmland in hot areas as livestock can use the shade to stay cooler and grass tends to grow better because there is more moisture due to lower evaporation.

It would be nice if large areas of black tarmac (roads and car parks) could be made lighter to increase reflection, but doing this would be difficult in high-traffic areas

Replacing dark roofs with a lighter-colored material would also be beneficial. Flying into CLT and MIA last week I was disappointed by the huge areas of warehouse rooftop with not a single solar panel - no doubt with air-conditioners working overtime to keep the buildings cool

Our near neighbors, a husband and wife, say solar farms can attract the beams from space lasers, and combined with the deadly rays from 5G phone towers, cause things like Covid, and brain cancers.
Says we should erect a small Yurt in our garden, and hang lots of crystals inside to purify our body systems.

Barely even a novice, but, while I understand that light colored and shiny things reflect the light, are you saying that a white roof reflects the sunlight all the way back into space so that it does not heat our atmosphere? I know that when I wear a white shirt, I am not nearly as hot as when I wear a black shirt in the sun. But I assumed that the effect was localized, i.e. while I personally was cooler, the heat energy still existed around me and was not reflected all the way to space so that the earth's temperature was lower.

Cause Global warming? Global warming has been going on for years. Farms with live stock - cows - have contributed to global warming. Farms are disappearing because the younger generation doesn't want to do the hard work in farming. Immigrants are the only people who will do the work. Solar panels are the least of our worries about global warming. Do some legitimate research on the subject.

That's partly correct...farming is generational...so when that younger generation is faced with continuing the family business or cashing out in acreage that is at an all time high in value....i can understand the choice. Unless I'm mistaken, didnt the developer here buy out several farms over the years to accomplish his goals?

Has the last ice age ended?

Glacials are somewhat better defined, as colder phases during which glaciers advance, separated by relatively warm interglacials. The end of the last glacial period, which was about 10,000 years ago, is often called the end of the ice age, although extensive year-round ice persists in Antarctica and Greenland.

I guess that is about the same time humans started using fossil fuels.

Have you been to solar farm? They kill off every living thing when they put them in place They spray for weeds regularly to keep the weeds from growing too tall to block the panel. Cows are not allowed into the area because cows have a tendency to rub on anything to scratch themselves. You should see what they bend and break at a farm. Now let's talk about the 100s of thousands of farmlands that are gone from producing food, I hope silicon tastes good. Then there are hailstorms that destroy solar fields, plus as they degrade they will have to be replace or abandoned. What is the plan to recycle them? As of right now, there isn't one. Let's face it, this is a boondoggle put in place to make some people feel good.

Vikings discovered Greenland in the 1500's. They named it Greenland why? Because the tundra was covered in green plant life not ice. In the 1500's there were no CO2 emissions from vehicles or manufacturing and the world's population was much much lower. I very much doubt that great changes in climate are caused by human activity. There is historical evidence that the main influence on our climate is solar activity and the solar minimum and maximum periods.

I think it is naive to think that we humans do not have an effect on climate change. There are far too many humans using up the earth's resources, tearing down trees and emitting all kinds of pollutants. How could this not affect the climate?

The YouTube video does show lakes, but they are now building windmills in the ocean so I can't imagine they won't be able to the same with solar panels. As far as lake front property and tax compensation, I'm sure something will be worked out. Farmers have been compensated for the use of their land and seem to be happy. Now to the fishing, one of the videos I saw claims this was good for fish growth and let's be realistic these solar panel will not cover an entire lake or ocean, so fishing will not be eliminated.
I purchased an EV on Monday and I'm fully aware there will be some benefits and some sacrifices, like almost anything these days. We just have to figure what we consider more important and can we except the cost.

“can we accept the cost”

To me anything is possible in your premise but most of us not likeminded would ask....is it necessary

To line the landscape, woodlands and waterways with these unsightly panels and turbines as you suggest...it’s like we’re going back to the 50’s/60’s and 70’s with antennas hanging off of houses and tenements. I’m fine with some sort of balance but nobody wants to be forced fed theories and subsequent practices....that are still wildly open to different interpretations and outcomes. I’m the furthest from being a tree hugger....but when I’m on a hike in Mt Washington Valley of NH.....I want to see natural resources, not panels and turbines

You might want to read the above article you cite in its ENTIRETY. Anybody can cherry pick quotes. From the article you cite, a damning quote:

“This cooling trend is partly due to natural variability and partly due to upwelling currents that bring to the surface deep waters that have not yet warmed because of anthropogenic climate change [e.g., Armour et al., 2016].”

In other words, the “cooling trend” of parts of the Antarctic Ocean (due to disruptions of ocean currents due to climate change) has YET to show the warming at the surface that will eventually manifest — due to “anthropogenic” change. Anthropogenic change is defined by the United Nations as: “Climate change refers to long-term shifts in temperatures and weather patterns. These shifts may be natural, but since the 1800s, human activities have been the main driver of climate change, primarily due to the burning of fossil fuels (like coal, oil, and gas) which produces heat-trapping gases.”

To paraphrase the old Shakespeare quote: “Hoist(ed) on your own petard.”

Unless I'm mistaken, didnt the developer here buy out several farms over the years to accomplish his goals? Not a bad thing for the model but from a business perspective, both parties seem to benefit from the transaction. Exactly, I grew up on a farm (my family still owns it) and over the years the surrounding land has been taken by industrial buildings, a highway and then a truck stop near by to support the highway. Being familiar with the solar industry, I get so tired of hearing they are taking the farm land. Farming is hard work and if you have animals it’s 24/7. If I had a choice of neighbors, a quiet solar field would be high up on the choices list.

It is sad to see the sheer ignorance exposed by all the folks who posted their "answers" to these two relatively simple and reasonable questions.




Reflection back into the sky is not really the way to look at this. Albert Einstein got a Nobel Prize for his paper describing the photoelectric effect (https://www.khanacademy.org/science/physics/quantum-physics/photons/a/photoelectric-effect) - but most know him for his later work in relativity. The engineering outcome of that knowledge resulted in capturing electrons that are emitted when light hits metal in an electric circuit. (Solar panels). Once those electrons have completed some sort of electric circuit, some work has typically been done and the difference between the total energy of the emitted electrons and that work turns into heat. Roughly only 20% of the radiation hitting the panel gets turned into electrical energy. Most of the rest is absorbed causing the panel to heat up.

Objects with a temperature above absolute zero emit electromagnetic radiation - you can look up black body radiation for more details, but it has been well understood since the 19th century. So the solar panel is always radiating energy in every direction, even at night! So, too, is everything around you, including your body.

Also well understood is that different gases absorb different frequencies of light. The absorbed energy raises the temperature of the gases. The gas radiates in all directions. Some radiates out into space and some radiates into the earth. The balance of energy absorbed by the earth and the energy re-radiated affects the climate (https://www.ces.fau.edu/nasa/module-2/how-greenhouse-effect-works.php#:~:text=Water%20vapor%2C%20carbon%20diox ide%2C%20methane,space%20and%20downward%20toward%2 0Earth.).

One of the interesting and observable effects of radiation of heat at night occurs during temperatures where the air cools enough that moisture condenses on grass. Often times you will see this and notice that the grass under trees is dry or drier. That is because the black body radiation of the grass got blocked by the tree which re-radiated downward warming the grass. So the grass stayed warm enough that water vapor did not condense on the grass under the tree.




The cell, per se, won't cause global warming. It will reradiate pretty much like the earth's non-water-covered surface.


As to the farmland loss issue, solar cells are more efficient at generating energy than vegetation. So trying to generate usable energy from plant production, like, for example, ethanol is relatively more wasteful.

I guess I'm not as smart as most replies. Common sense tells me there is a reflection up into the sky. Loss of farmland might not be important to some, but only the sheep eat the grass under all these panels. Then in 20-25 years they will need to be replaced. Hopefully they won't leak much before being replaced.

I guess I'm not as smart as most replies. Common sense tells me there is a reflection up into the sky. Loss of farmland might not be important to some, but only the sheep eat the grass under all these panels. Then in 20-25 years they will need to be replaced. Hopefully they won't leak much before being replaced.
What is there to leak it’s made out of silica and minerals.

Someone looked? Oh boy..... tell that to the Polar Bears.

Agree about the Polar Bears. I've seen video of Polar Bears being stranded because their polar ice is slowly shrinking.

Polar bears are excellent swimmers. They weren't "stranded". It was a purposely chosen angle, ignoring all of the ice behind the photographer...

It's like Bear Grylls, who used specific camera angles to make his "stunts" look dangerous...

You forgot to mention toxic heavy metals such as lead, selenium and cadmium.

Solar panel fields are showing all over the country. Loss of farmland is my biggest fear. But what does the reflection back into the sky effect? Could this cause global warming?

The farmland is not lost to solar panels, the panels can come down and plants go in at any time in the future.

Farmland lost is TV development where the land is permanently lost to housing which isn't going away . .

Ergo, unfounded fear and faulty logic considering you are living on lost farm land. . .

You might want to read the above article you cite in its ENTIRETY. Anybody can cherry pick quotes. From the article you cite, a damning quote:

“This cooling trend is partly due to natural variability and partly due to upwelling currents that bring to the surface deep waters that have not yet warmed because of anthropogenic climate change [e.g., Armour et al., 2016].”

In other words, the “cooling trend” of parts of the Antarctic Ocean (due to disruptions of ocean currents due to climate change) has YET to show the warming at the surface that will eventually manifest — due to “anthropogenic” change. Anthropogenic change is defined by the United Nations as: “Climate change refers to long-term shifts in temperatures and weather patterns. These shifts may be natural, but since the 1800s, human activities have been the main driver of climate change, primarily due to the burning of fossil fuels (like coal, oil, and gas) which produces heat-trapping gases.”

To paraphrase the old Shakespeare quote: “Hoist(ed) on your own petard.”

I'll believe the Magic 8 Ball before I believe anything the United Nations says.

It’s a point many of us have brought up on this topic SG....the same ones that are sounding the lost farm land alarms are the same ones that seem to have no problem reconciling those conflicts when closing on their respective TV forever homes!

Sorry to be late to the bashing. . just got back from 6 weeks of traveling, and trying to catchup. . . hoomans, just one enigma after another conundrum.

I promise not to pile on again, boss

I'm not a solar panel expert, but I thought the purpose of a solar panel was to capture and absorb the energy from the sun and to convert it into electrical energy. So, your fear seems to be the opposite of what really occurs.

The do reflect back, you can spot them when in plane gigantic glare.

So population reduction is in order? I think we’re living on cattle grazing land? Now if villages was in nice river bottom where dirt fertile due to centuries flooding then yes. Dirt in Florida very low end of fertile.

I think it is naive to think that we humans do not have an effect on climate change. There are far too many humans using up the earth's resources, tearing down trees and emitting all kinds of pollutants. How could this not affect the climate?

I agree need ban chainsaw, D8, 9, 10, and 11 bulldozers, and anything over 5 bottom plow. Also need volunteer reduction in population. O and free birth control pills and mandates on child numbers, no more litters… :22yikes::loco:

They should cover rivers/lakes with solar panels to reduce loss of water due to evaporation. Especially out west where there is routinely drought problems.


They’re doing that in water reservoirs with millions of black round floating balls.

your logic escapes me. . no idea what that word salad means . . or what you are trying to convey. .

what you are describing is bio-diversity collapse. . .

The effect on climate is more about humans creating a bigger solar radiation heat sink by replacing green areas with steel, asphalt and concrete, which absorbs and retains heat and is capable of raising the local temperature significantly

As far as climate change, the earth has been warming for at least 10,000 years since the last ice age, though there were no thermometers back then. . however the thermometer with a standardized scale is only about 200 years old, so there's a bit of excessive extrapolation going on as a mind game using fear. .

You are living in the perfect solution. Every house and building in The Villages should have solar on the roof. No wasted farm land, lots of sunlight and solar for a population which requires a large amount of electricity. Win-win.

This is basically the opposite of common sense. The solar panels are black to absorb as much light as possible. Why would they possibly waste time in their design reflecting any light back up to the sky? There's no reflection. I have solar panels on my shop up North. They work great. I have them mounted on a steel roof and the excess heat goes down not up as I can hear the roof expanding from the heat on a sunny day.

Many new housing developments here in the UK incorporate solar panels in the tiling of the roof. They are part of the roof, not great lumps put on after roofing.
Any unused electricity generated is fed back into the National Grid, and the owner gets paid for it.
All we lack is the amount of sun that Florida has.
Never understood how a State, with as much sun as Florida, does not make it mandatory for new builds to have solar energy.

Economically it does not seem to work out for us old folks. Also when shingles need to be replaced after 15 years or so, not cheap to take down and reinstall the solar panels

I'd be worried about hailstorms ruining the solar panels
