Imagine if you put a mirror under the sun, it heats up and the light is reflected back. How is solar panel different from this concept? Does it uses a special material so the heat will not bounce back to the atmosphere and make our Earth more warmer causing more global warming and helping to melt down the iceberg in north and south pole? Are you a genius? answer my question

I used to install solar heaters and we used a matt black type panel. These would absorb heat and reflected a lot less. These also did not have a glass covering so were exposed directly to the sun.
For glass covered ones for electrical generation, use a laminate cover on the glass that has a matt finish and there will be less reflection. You’ll only lose a little of the effect of the light but will also give the glass a coating that will reduce breakage (the laminated film will help keep glass together and will resist small impacts).
Now I’m no genius but I am pretty sure that solar panels do not take in heat, but the energy the sun gives off. Next time you see one up close, look at it. I don’t think they really look like mirrors. They are made up of:
‘a glass covering and a frame and backing made of metal, plastic or fiberglass, are known as a photovoltaic panel or simply solar panel’
Even if they are somewhat contributing to Global Warming, they are still 3000 times better than burning Fossil Fuels to get our Energy. If everyone got a solar panel, than I think the polar bears would be much happier.
They don’t reflect much but even if they did, that energy is still pouring down, regardless of whether it hits a solar panel or the ground.
The idea is to reflect the light not hold it in the planet causing global warming. The problem is all the smog and other crap we have been putting in the air that is blocking the reflections and causing global warming.
If all the smog is blocking the light from reflecting back out into space then why not stop making smog? Seems that solar panels would slowly shut down smog making power plants. So the less smog the more the planets water bodies and solar panels could reflect the light and and the smog would not be there to asorb it meaning less heat.
Heat is bad for a solar panel. (Note: a solar panel is made up of solar modules and a solar module is made up of solar cells.) The colder the solar cell is the more electric power it puts out.
What that is melting the icebergs is not that the water and solar panels and roofs on cars are bouncing the light back out but again the junk in the air is collecting the heat and heating up. So the more smog the more light is blocked and the more heat buildup. Then more iceburgs melt making more water which reflects more light back in to the smog and makes it even hoter and melts more ice.
Get the picture?
don k is right. except solar thermal panels absorb heat to, of course, to heat water. to even think that solar panels heat up so much to attribute to global warming has to be the most idoitic, clueless question i have ever read. we are all dumber to have read it. does your hot breath cause global warming? It gets hot under your arm pits and behind your legs, must be melting ice bergs with that body heat, right?
well i dont think that the heat will feed back from that metal ..they uses a special kind of metal for that purpose…
