Not yet, but will do when we extend, so I've been looking into it just
recently...

Evacuated Tube panels work fairly well in winter as well (where flat
panel ones don't do so well), and you could size your solar panels to
provide enough on average to supply you all year round, but that will
mean in the height of summer you'll have way, way, more hot water than
you can possibly use (Summer to Winter insolation ratio is 10:1 if
I've understood correctly), and there will always be cloudy days...
You might find the Navitron and greenbuilding forums helpful (I
certainly have):
