Intersting read. I've always been skeptical from the full-life cycle of components perspective (same happens to wind turbine blades). One issue I didn't see in your article is that not every country is capable of producing solar energy year long and transporting that stored energy is also costly. Take Brazil for example: we have a massive hidroelectric potential, but most of that energy is stored in rivers in the middle of nowhere, where building power plants is just way too expensive. So it all boils down to cost. As you said, as the technology evolves, costs tent to go down.
Anyways. Our family business is converting to solar, since the energy bill is higher than a loan to convert the building to solar. In the mean time, it's just not financially worthy to convert our house (if the energy bill keeps on inflating it might be worth soon).
Thank you very much for your opinion and point of view.
You are certainly right too.
