| May 29, 2016 at 8:22 | comment | added | Russell McMahon | Larry OBrien's superb 2012 reference The energy balance of the PV industry provides an excellent overview of what you want. They say in summary that new panels exceeded energy use in manufacture in 2015 and that output of all panels ever produced will exceed energy used in manufacture by 2018. | |
| Sep 14, 2015 at 11:04 | comment | added | GordonM | I know you're asking about the second claim (the amount of energy needed to make a panel) but I have some serious doubts about the first one too (the one about every solar panel in the world producing the equivalent of 2 coal power stations worth of power) | |
| Sep 7, 2015 at 20:43 | comment | added | jjack | How much coal-equivalent goes into building a common coal-fired electric power plant, by the way? | |
| Apr 19, 2015 at 13:06 | comment | added | jeromej | For those interested, there is the cached version of the deleted answer myedit.io/v.php?is=1904b8778691 . @Skliwz let me know if I am allowed to link to a deleted answer or not. IMHO I see why this deletion system is established but I also see a flaw in that very system… Thanks anyway. Have a good day. | |
| Apr 19, 2015 at 9:56 | comment | added | Sklivvz | The answer had objective problems, it was lacking references in a critical part and this lead to an unwarranted conclusion. You can read about them in Skeptics Chat. After addressing them, the OP got to a similar answer as the one currently visible by Larry. We are waiting for him to update the text to undelete it. As it is practice pretty much anywhere on the network, you can't expect to read off-topic content for any length of time. Unreferenced material is, unfortunately, off-topic on skeptics. | |

| Apr 19, 2015 at 1:41 | comment | added | jeromej | @Sklivvz Even if OP was (wrongly?) satisfied with the answer (I accepted it)? Ok… seems weird to me. Also, even if you guys disagree about it, I'm sad I can't see it anymore somewhere: Whichever its actual accuracy was, it was a start at least, definitely something I would want to still be able to read now. Even if there was a lot of extrapolations, it is much more documented than in the video. Also, but that might be only my personal opinion but, "multiple attempts" = only one day? Seems short to me, some people can't afford such short delays to SE. Can I still see the answer anywhere? Thx. | |
| Apr 19, 2015 at 1:35 | comment | added | jeromej | @DavePhD Common sense would tell me it would be a "standard" size one if not specified. The point here was, the number feeling so huge, that your "solution" could have been answered by a really giant solar panel, in which case the information would have been much fallacious in the way presented in the video. | |
| Apr 19, 2015 at 1:33 | comment | added | jeromej | @EnergyNumbers Thanks for insisting on this point. I could/should have been more rigorous about this concern. | |

Please avoid back of the napkin calculations because: jameskennedy.ie/wp-content/uploads/2014/04/… | |
| Apr 18, 2015 at 16:05 | comment | added | DavePhD | Without specifying the size or capacity of the solar panels, it is a meaning less statement. However much or little energy it takes per panel area, there will always be a size that would take a given amount of energy (such as 1 ton of coal equivalent). | |
| Apr 18, 2015 at 15:03 | comment | added | 410 gone | NB there is a difference between "the equivalent of between 1 and 4 tons of coal" and "1 to 4 tons of coal": solar panels don't need any coal per se. | |
