I read over the weekend that silver is widely used in solar panels. Thought that was interesting.

From Google:

How Much Silver Does a Solar Panel Use? An average solar panel uses some 20 grams or 0.643 troy ounces of silver. Two-thirds of an ounce of silver in every solar panel may not sound costly given today's silver spot price.

Silver has been used in solar panels for several decades. Due to better manufacturing techniques, there is much less silver per kilowatt than when we played with them in high school shop class over fifty years ago. The difficult part is recovery of silver and other materials in an economic manner once the panels become waste.

Time for more coffee.
