Precious Metals In Solar Panels

There are a lot of things to like about solar power.

Precious metals in solar panels.

Basically anything that has an on off switch includes copper thanks to its incredible ability to conduct electricity and we. An average solar panel uses some 20 grams or 0 643 troy ounces of silver. Experts have found that the rare metals required to build solar panels such as indium and tellurium are not in sufficient supply to keep up with demand. Thin cheap solar panels need tellurium which makes up a scant 0 0000001 percent of the earth s crust making it three times rarer than gold.

But it needs the sun to work which makes it less practical in places where overcast days are common. There is also talk of substituting silver with copper in solar panel production. But silver s cost contribution to solar panels outweighs its proportional expense over virtually any other application it has other than perhaps jewelry silverware or in 999 fine bullion coin or bar form. Researchers are using bacteria to give solar an energy boost.

Two thirds of an ounce of silver in every solar panel may not sound costly given today s silver spot price. High performance batteries need lithium which is only easily extracted from briny pools in the andes. Silver s use for solar panel manufacturing is around 80 million troy ounces per year or currently about 8 of annual silver supply. It helps the world kick the fossil fuel habit it s clean and plentiful and leaves no carbon footprint.

Precious silver bullion metal we buy and sell here at sd bullion has more applications than virtually any other limited resource we use other than perhaps crude oil or fresh h2o.
