PV Solar Panels Materials List

The most common type of PV panel is made using crystalline-silicon (c-SI). That technology accounts for 84% of US solar panels, according to the US Department of Energy. Other types include cadmium telluride, copper indium gallium (di)selenide panels, and thin-film amorphous silicon. Because c-SI panels compose most of the US and global market, I focus on them in this blog.

What’s in a solar panel? By weight, the typical crystalline silicon solar panel is made of about 76% glass, 10% plastic polymer, 8% aluminum, 5% silicon, 1% copper, and less than 0.1% silver and other metals, according to the Institute for Sustainable Futures.

Wait. Where is all the cement?

(referring to the thread discussion the tons of cement (not concrete) used in solar panels)

Used structurally in large solar arrays?

Where on large solar arrays would you use cement?
Here are some pictures that show you why there is no cement.

In that link, on the back-side of the panels are several support columns or pillars. Those support pillars appear to be anchored in concrete. Portland cement is a major part of concrete. Or, the cement referenced in the other post was in regard to the synthetic glues or epoxies used in the manufacture of the panels, which is a real thing.

Wrong!

The table you presented showed concrete and cement as separate line items. So they are not duble dipping.

There is no synthetic glues or epoxies in the manufacture of solar panels that weigh more than the glass in the panels. Just look a the materials list in my OP.

Why not just stop guessing and give up on the meaning of your 10 year old table that you do not understand and can not explain to anyone else.
