Solar diverting excess to tank or using solar to power the ASHP to heat

It can be clearer to think about it in terms of price if you have a reasonable export tariff. If you can export 1kWh solar for 15p and add 1kWh of heat to the tank with an ASHP for ~11p (33p/CoP of 3) then worst case (no solar) you are still 4p/kWh better off.. That only gets better if you happen to have excess solar during the ASHP schedule, as the ASHP will then
