We are moving to France in a few months to a house that needs

thinking that instead of putting in the usual electric water heating
system that is common in France, a solar system might be nice.

They're hardly ever good value where mains power is available.

I've seen consistent proclamations that a solar DWH system is the best buy
for the money that can be made after pure conservation.

And those comaprisons are verses natural gas. I would expect solar verses
electric to be a very good proposition.

Why would you think that isn't true?
