I don't understand - are you comparing the efficiency of solar cells at converting sunlight into electricity to the efficiency of an ICE at converting hydrocarbons to mechanical motion? Aren't those completely different types of processes with no relation to each other?

Agreed. It’s a total apple to oranges comparison.

You can convert W | VA to HP although there is a multiplier. I don't understand the comparison much either, as solar beats ICE in carbon footprint every time.

Probably because solar power is energy return over 20-25 years, while oil wells front load their energy return giving ~50% in the first year of operation.

So you are correct they aren't really comparable...which is a real problem for energy security and the viability of solar in EROI terms.

More like apples to rocks. Sometimes they are both roundish.

Yah, this is easily one of the dumbest comments I've seen on this sub. That and the person that said to ban EVs.
