You’re talking ROI. I’m talking efficiency. SHW is about 65%-70% efficient. PV is about 20% efficient.

Efficient with money means you get more of that world and environment as savings per dollar.

Would you choose paying €4000 to replace 600 kWh of heat pump boiler hot water with solar boiler, or 4000 kWh of basically a whole home's energy usage including hot water?

The solar boiler doesn't even heat well during all seasons, mine still uses gas to back it up at least half the days.
