9. Never understood the efficiency angle on solar PV

It matters little if it's 8% (that's way low) or 40% as long as they break-even way before the warranty is over. Buy good quality today and the warranty is 80% of rated output after 25 years (which would imply that 50 years isn't out of reason for service life).

Nobody spouts how inefficient an IC engine is and how long the supply chain is to get gas to your local gas station. Typical IC engine is lucky to get 20% thermal efficiency.

Edited to add >>>

Efficiency in Solar PV is less relevant because you don't pay for the fuel - or at the Koch Bros haven't figured out a way to make us pay
