Oh no. Water heaters are the most efficient form of solar. Newer solar water heaters might be a bit more efficient than old systems, but we are talking like 80->90%. PVC solar peaks in the 20% range.
What’s funny is it’s enough energy that a heat pump water heater + solar ends up being more efficient than a solar water heater. Especially in a warm environment.

20% of a looot of energy is still a lot though
