Just taken my occasional set of readings and it looks like this has been the ideal summer...

In the ~100 days between 9-May and 17-Aug, we used only 12kWh of grid power to heat 300litre DHW; the rest was all sunlight.

Thank you Ivan and Navitron for turning me on to solar thermal... it works!

My system installed in 2005. makes most of the hot water each summer and has never had a fault and only two services.
Excellent, probably the most satisfying of the technologies I have used.
The collector is so much more efficient than PV and hence much smaller for the same duty and getting paid for export means I certainly don't want to use electricity for DHW.

Schuco solar hot water - 3300kWh/annum, 16 BP 4175N PV panels - 2.8kWp, log burner and back boiler and 18 Ying Li 235 PV panels - 4.2kWp, 42kW ground mount PV, 9kW Panasonic ASHP, 40kWh Nissan Leaf
