Solar hot water has to account for pumping losses as well, its going to be in the same ballpark but the electric heat pump hot water system is much more flexible in how the power is used and decouples production from use along with electrical vs plumbing on the roof which is simpler and dare say less prone to issues. Solar thermal heating used to make more sense but cost of photovoltaics has come down so much along with relatively cheap heat pump systems nobody is doing the former anymore it seems. I just got a large solar system installed and next up is a heat pump water heater as thats the second largest user of power next to the HVAC, plus it will cool and dehumidify my garage some where the solar inverter and batteries are located, converting some of the waste heat from the inverter into hot water at the same time.
