No. You can't get more waste heat from charging batteries with solar
power than what you get from solar energy warming the planet directly.
You can't get more energy out of a system than you put into it.

Except for the initial habitat destruction incurred by the creation of
the reservoir in the first place.

Mechanical storage isn't any better than chemical storage. It's
different with different problems like friction and mechanical wear.

The problem isn't how we store electricity. It's that we store
electricity. Regardless of how we end up generating electricity,
converting it for storage and then converting it back for use will
always be less efficient than using electricity directly.
