The Mystery Flaw of Solar Panels

1. Fossil fuels is is a democrat shadow word,oil is not made from fossils or skeletons of any form.

2. The flaw is that they only work in daylight..lol

3. Is this a Brilliant add?

4. Wait until they charge you for a view of green…

5. ❝forcing fossil fuel producers out of the market❞

   Pffft, yeah right! 🤦‍♂ Won't happen unless ❝green technology❞ can outperform fossil fuels, and at the moment it's not even close! I wish it was, but just because I wish it, that doesn't make it so! 🙄

6. Oil is green energy, it is all the dead life (plants, animals) over millions of years. Renews itself over time rare earth elements are mined used and gone

7. You explain why we need your sponsor better than most other Channels (even for the exact same sponsor!), probably because you are being honest about what you know and don't. Thanks.

8. Another SALES video, Brilliant SHOULD be FREE to ALL humanity ! Only GREED keeps Us from Evolving !

9. All P-N junctions suffer from heat, which is why electronics that gets too hot suffers thermal runaway and loses its properties…

10. It only just occurred to me that plant leaves being green means that they are reflecting the peak band of the Sun's energy output and absorbing everything else.

11. Can solar electricity charge an EV's battery?

12. The very beginning of this video tells out-right lies about implementation and cost of this regressive junk ….

13. I would think the real problem or limitation is the 80% they are not converting to power, rather than the 2% loss of an already proven and functioning system.

14. Mystery flaw, my brother in christ, the entire green energy movement is one of the most elaborate money making schemes in history. Besides Nuclear, none of these energy production methods are efficient enough to run industry, nor are they actually green.

15. 00:22 "…forcing fossil fuel producers out of the market through technological advance."—more like, "forcing fossil fuel producers out of the market through marxist green corruption and government coercion."
    00:32 "Solar capacity US TOTAL 630,000 MW(•hr/yr?—incomplete units here)" vs ONE hydroelectric plant (Grand Coulee) 21,000,000 MW•hr/yr—so for EACH dam the greenies want to tear down, we just need to multiply current solar capacity by 33.3!
    Beginning to wonder if this vid is a waste of time…

16. I bailed after the first 20 seconds "Forcing fossil fuel producers out of the market through technological advance!". This is a LIE. Solar is being subsidized my MY TAXES. And natural gas, and gasoline is being pilloried by governments, and NGOs like WEF, and are being canceled by Biden. Wake up! So I'm sure you have a slick video. But I don't need the "global warming, dirty petro!" religion, thank you. I'm outta here! I don't need Chinese child slave-labor to dig my "clean solar"!

17. Please improve your grammar.

18. So where does the pollutant 'cadmium' come into play? We purchase the vast majority of our solar cells from China and they are not recyclable because of the poison, cadmium, in them and they have to be deposited in special hazardous waste land fills when they expire. The USA manufactured panels have less cadmium in them, so they are better to use as far as our planet is concerned. BUT, all of those very nice solar programs don't give us a choice, we are forced to use cadmium cells for cost reduction. So…. I refuse to continue to poison our planet, even though I WANT solar on my roof, when there are less polluting products directly available. So what is our answer to THIS problem?

19. It is NOT that solar cells are so great that they have replaced fossil fuels. It IS because of government interference in the energy industry and taxation! No? Then end all green energy subsidies immediately! No??? Lol I thought so.

20. Better yet use reliable coal, oil, and nat gas for reliable energy.

21. The first part was good, but leading into a sales pitch, not cool.

22. Nice to see someone digging deeper into a relatively stereotypical and popular source of renewable energy. Unfortunately I think most people don't know enough about the disadvantages of Solar energy. How the panels themselves become toxic waste, and how they require a lot of area to create a small amount of energy. Area that often provided a home to many different animals and species. I found this information all in a recent TED talk called Why Renewables Can't Save the Planet if anyone's interested.
    The problem of protecting the Earth is perhaps the biggest problem our species have faced, and I'm excited to see how we're going to continue to face it.

23. Replacing good farm land with solar deserts should be ever so obviously morally wrong, not to mention counterproductive to the reduction of airborne carbon. Solar produces electricity only a 4 to 5 hours a day. It is therefore not a viable addition to the grid where other power sources can't be ramped up on and hourly basis. Fossil fuel generators ramp up in days not hours. Solar panels can reach 150ºF. So if they are massed in farms (some as much as 1000 acres or more) they can generate and exacerbate thunderstorms and tornadoes. But they can also generate cooling at night because they produce “black body radiation”. So solar farms can exacerbate weather extremes. Solar has it's place but replacing farm land with solar is counterproductive to saving the planet.

    There is no “green energy” that can survive without tax incentives. That should tell you something right there. “Green energy” isn't truly viable.

    This is what you get when politicians with no science or engineering background try to design your future for you. And all the more especially when their primary motive is their own personal avarice, not to mention their moral and intellectual bankruptcy. If it takes 600 unelected officials to fly their private jets to some remote location to tell you to ride your bicycle to work there is no climate crisis. The only thing green about green energy is the dirty money flowing into corrupt pockets.

24. The whole video starts with pure unadulterated bullshit – aka religious propaganda of the doomsday cult of climate change. Carbohydrate fuels are put out of business by TAXATION and REGULATION. The Toxic nonrecyclable and nonrenewable "renewables" cult is subsidized by hydrocarbon fuel industry. And only uneducated moron with single digit IQ would call hydrocarbons "fosil" – yes, it's the pinacle of 4 billions of years of evolution but everything alive on the planet still runs on hydrocarbons – including us. It's the most diverse, most stable, most environmental friendly solar based power source that's completely recyclable by the environment itself AND without ANY toxic byproducts

25. Also a HOT panel in the Desert is 10% less efficient than a panel in the cold of winter in Colorado.

26. Another flaw of solar panels is they’re not worth recycling adding more materials to landfills that eventually will leak into groundwater. A product as inefficient as today’s solar panels should not be allowed to proliferate on the scale they have thus far until R&D can make them more viable & longer lasting. A job for DARPA.

27. I still can't believe he said that plants evolved that structure over millions of years (12:05–12:14). How embarrassing to include such BS in a scientific explanation. Evolution is not scientific. Just think about it! A plant had to survive for millions of years to develop a structure for survival. Cut down a tree in a forest and see how it dies in a week. It won't evolve new roots and here you're suggesting it can lay there for millions of years to evolve new information. Trees do not have a conscience and even if they did they could not evolve themselves at will the same way you can't evolve tolerance to radiation poisoning or a granade. I would suggest give God the credit for the leaf design or leave out origins all together.

28. Very well explained for a non technical audience.

29. The electrones barely move through the circuit, it's an electromagnetic field which does all the job.

30. if the solar panels are losing electricity to heat, couldn't we use some kind of fluid to capture that heat and use it to drive a turbine?

31. engineering is applied science, which means that engineers are not scientists themselves, they just apply other people's findings, which is why so many of them are nothing but frauds

32. Doesn't matter. There are still places on earth that don't get much sunlight year-round. These places will continue to require gasoline for the foreseeable future just to say warm and bring in food and building supplies. Unless these panels can replace gasoline in these areas and batteries can be heavily insulated from the cold. Gas isn't going anywhere.

33. Let's hope I find this again when I have to put this info into the eight-page report I have due in 3 weeks.

34. The one thing I asked in electrical school was what will the impact of the solar panels be ..teacher at first looking a bit confused said GO ON so I completed my question ..when will the tipping point of panels be negative .as in when will we have so many panels that it will heat the environment even more as they reflect a certain amount of light back above what naturally bounces back combined with the current contaminates issue of smoke particles causing the planet to heat ..if u don't know what I mean picture a hot car in the sun…how much hotter does a darker car get compared to a lighter car …then if we're to put mirrors in the car so even more infra red heat bounces off the interior to get trapped inside the car …can u see where I'm going with this …
    It's similar to the methane gas under the permafrost ..it's not sumthing that was included in the science but it should be it just wasn't thought of …teachers response was WOW BEST QUESTION EVER ..didn't have an answer but agreed that I was on the money

35. Good depth dive in solar energy concepts

36. Cover every square inch of earth's surface in solar panels and mirrors to reflect even more light, then move everyone underground…Boom, done

37. Nuclear power is much more effecient

38. Crazy how this video is 2 years old yet it's super outdated already 😊

39. You lost me at “the holes jump into the n-type” how tf does a hole jump. Wouldn’t the electron just fill that hole to form a covalent bond?

40. Wonderfully well explained

41. Why does it rain on the two cars parked in front of my neighbors house with solar panels at sun rise

42. Wait

    Why The Heck Is Ancestry's Channel and Video included on this playlist? Aren't they a genetic data risk — AND A WHOLE OTHERE CHANNEL?

43. The explanation about how the solar cells work is a little wrong in my understanding. A lot of other YouTube channels explain the same way. The P-N junction occurs naturally when coupling P type and N type. It will create an electric field between these layers. The strength of the field depends on the material. With silicon it's about 0.7V. Photons have to hit the P-N junction area where holes are being occupied by electrons in order to kick them out of the holes. Then the electron will be accelerated by the field. There are 2 directions it can go, one is to pass the PN junction to go back to the N layer, or the other way is through the load, which generates electricity. That's why we are trying to expand the P-N junction as wide as we can, by heavily dope the N layer which is the top one and lightly dope the P layer on the opposite side. If a photon hits the N layer, nothing will happen because they always have free electrons moving around. So with heavily doping, N layer will be very thin that electrons can pass through easily. So it's the field created by the covalence bond of Silicon that creates the potential, and photons are like the hit that releases the energy. That's why silicon cells can only generate below 0.7V. With other materials like SiN that we can create higher voltage because the bandgap is wider. Hopefully you can justify this so when the new generation watches your videos, they can understand more deeply and accurately. By the way I really love your work also. Keep pushing
