Thanks for clarifying. You might reach a different conclusion if you take a look at some industry guides, for example "A Guide to Metals for Solar Suppliers" published by Kloeckner Metals in 2022. My company installs commercial solar arrays; our experience has been that all the components have become more affordable and more easily available. With the ramp up in global manufacturing capacity, industry publications are predicting a glut of solar equipment. But you may be right -- there may be unexpected glitches as the supply chain expands.
