Another way to understand EROEI is, given a solar panel system (including batteries, circuits, etc) typical lifespan of say, thirty years, how many other systems equal to this would you be able to build with the resulting e energy during those 30 years? It’s improving, but if you also account for the maintenance and required labor to keep it working, it’s still looking really bad when compared to the output we had from fossil until a few decades ago.
