Home electricity bill of a decent GPU alone is usually more expensive than renting GPUs on demand.

Do you have any numbers to back that statement up?

E.g. I have solar panels and a home battery and pay less than a $100 a year for electricity.

Solar panels aren't free. And aren't hassle-free either.

I wouldn't even bring that into the equasion since a large part of the population can't use solar panels.

Not to mention GPU value depreciation.
