$this->bbcode_second_pass_quote('lonewolf', 'P')V panels require the metals Indium and Gallium in their manufacture. Both are exceeding rare earth elements, already in extreme demand (and constrained) relative to Earth's (in)abundance.
Only
about 15% of panel production requires rare earth elements, and most of that is
CdTe that doesn't require Indium or Gallium.
$this->bbcode_second_pass_quote('lonewolf', 'H')igh-grade silicon is also increasing constrained and energy intensive to produce. There is NO way that even 20% of American'ts can have 'their' PV panels much less the rest of the planet too. Even if we gave up all flat screen TV/s/monitors and recycled the metals in all that exist, only a few % of the US population could access PV.
"Alternative energy" is an oxymoron and a deliberate LIE. There is only one energy source on Earth, namely Sol. PV panels are made from 'fossil' solar energy just like 99.9% of everything else you have, know, use to stay alive. PV panels/systems are NOT remotely "sustainable"- PERIOD. People who promote 'alternative energy' as a solution or some sort of panacea are effing deliberate MORONS, and therefore effing dangerous.
Another note, PV panels may in fact last "a long time" (25 years+ they claim). However, the charge controller does not last nearly as long. Nor do batteries. From personal experience, (top-quality) solid state charge controllers last from 2 to 4 years on average and must be replaced with regularity or the PV panels become entirely worthless (zero usable output). Similarly, batteries must be replaced. Minimally discharged, properly maintained high-quality lead-acid batteries last no more than 10 years even if oversized relative to daily loading.
To 'think' that even a significant fraction of US connedsummers can ever access even minimal solar panel systems us categorically and utterly delusional - even if they were given away free of charge. The materials do not exist, the energy inputs do not exist (unless extracted at someone(s) else's expense), and the support/maintenance systems will not exist/continue.
Green is not only the newest Ponzi scheme, but is also the new religion and the new wanton delusion for promoting mass complacency and for continued ignorance of the extent/degree of your personal problem(s).
OTOH, don't get me wrong, I do 'luv' my off-grid PV system. I can watch as 'civilization' implodes with hot buttered popcorn from a relatively safe distance and be 'lovin' it'. Which makes me a complete asshole and glad of it. Bye bye bipeds.
You claim to have an off-grid PV system, but don't know that most panels are still made w/ good old Si, and the majority of thin film panels don't even use Indium or Gallium? Hell, most inverters are warrantied for
. I'm guessing that you're just BS'ing in order to spread FUD, but I suppose it's possible that you have no clue about your own system and are getting ripped a new one purchasing inverters every couple years. For that matter,
since then, so saying that 99.9% of everything made comes from FF energy is bunk. How's that astroturfing going anyway?
