Comment on solar PV → heat pump → water heater; direct, no A/C or intermediate components. Practical? Feasible?

IIUC, it’s variable D/C which must be regulated and/or inverted to A/C involving more hardware, conversion, and waste.
Actually, I had a discussion about this who really knows this stuff recently, and we figured that the inversion process isn’t actually that inefficient. The efficiencies achieved are often >95%, so there isn’t actually a lot of loss.
