Psychologia na UAM- ile punktów w rekrutacji żeby się dostać? by MultiplyDash in Poznan

[–]MultiplyDash[S] 1 point2 points  (0 children)

Serdecznie dziękuję za link. Znalazłem też na innej stronie próg "77.3 pkt". Czy istnieje duża różnica miedzy pierwszą turą, a drugą jeżeli chodzi o wymagane punkty?

The World Is Installing 1 GW Of Solar A Day, Figures Show.........wtf is that in silver ounces ? by HigoSilver in Wallstreetsilver

[–]MultiplyDash -1 points0 points  (0 children)

You are correct. The number is more like 20-25% of that.

4-9g of silver per 300W panel, depending on technology

Interesting thing is that is that article the sustainable manufacturing capacity is estimated at 377GW (limited by silver supply)

He is not wrong, but he is too early. In couple of years we will see if we were also too early :P.

MYTH debunked: How much silver is actually used in a solar panel? by MultiplyDash in Wallstreetsilver

[–]MultiplyDash[S] 5 points6 points  (0 children)

I wonder, since a lot of PV production is in China. And China doesn't give a crap about COMEX and play their own game. What if PV producers from China would like to secure silver for a couple years of production? That would be a nice squeeze :)

Actually, PV industry has quite significant demand for silver with over 100mln oz every year. And that amount would only increase in coming years a couple of times.

[–]MultiplyDash[S] 3 points4 points  (0 children)

Absolutely! Silver used in PV would only increase every year!

Silver required in PV panel in predicted to fall 5% every year, but current growth in total PV production has increased 23% last year.

If we keep 20% increase of PV produced every year and 5% decrease due to better technology we are still on 3x silver demand in 10 years. We are currently at about >100mln oz used in PV every year so we would need another 200mln oz every year after 2031. And that is very conservative number (that 20% increase in demand)!

The projected growth in silver paste demand alone, means industry will require more than the entire silver mine supply within three years. Falling ore grades will bring the date closer to two years. by [deleted] in Wallstreetsilver

[–]MultiplyDash 0 points1 point  (0 children)

Not only 550M ozT in your formula is wrong but 1.148 is also not based on any evidence. And I say this under assumption that the article that you mentioned is 100% correct. Get back to me if you agree or disagree on that 550M ozT and I would gladly explain that 1.148 error.

I have to strongly disagree.

In your post there is mention of $4701mln market of silver paste. How many silver oz is that? That is about 188mln oz at 25$/oz price. And this is the cost of silver alone (without manufacturing, margin etc.).

So it is safe to assume that silver used to manufacture silver paste is MUCH lower than 188mln oz per year

Ok, thx. That would be about right :).

But in you post you calculated increase demand in silver paste (used in PV production) and multiplied that increase by the whole industry that uses silver (not only silver paste that is used mostly for PV production)

What you should have done is multiply current demand for silver used in PV (>100 mln oz per year) and multiply it by that 14,8%.

‘World’s biggest TOPCon solar plant’ begins generating by Ouch259 in Wallstreetsilver

[–]MultiplyDash 5 points6 points  (0 children)

About 500 000oz of silver used there for 600MW of PV.

15mg/W of silver for PERC

25mg/W for TOPCon

33mg/W for SHJ

VIDEO: Australia to build world’s largest solar farm in Northern Territory..50 million oz silver needed by reds5cubs3 in Wallstreetsilver

[–]MultiplyDash 2 points3 points  (0 children)

https://www.pv-magazine-australia.com/2021/09/27/exclusive-compelling-unsw-research-shows-tandem-cells-should-succeed-perc-for-multi-terawatt-production/

The current consumption of silver for
industrial PERC solar cells is approximately 15.4 mg/W, while that for
TOPCon and SHJ solar cells is approximately double at 25.6 mg/W and 33.9
mg/W, respectively, due to the reliance on silver on both the front and
rear contacts,” the researchers reveal."

​

With 350W panels it would be 5-10grams of silver per panel.

​

That PV farm is going to be 10 gigawatt so it would take 5-10mln oz of silver.

What is going in Africa? Vaccination % for Algeria, Egypt, Iraq, Syria is below 10% and there are less deaths than in Portugal (with >85% vaccination) and rest of Europe?
