@gary @toodles @majordennisbloodnok Thanks for the comments. Im working up a simple excel model to test various tariffs based on load from the m...
Yes, Im sceptical about the longevity of some of the more extreme current tarrifs and any info about likely future tarrifs would at least allow a fain...
@toodles , @gary Thanks. Im developing a simple excel model that I can plug various tariffs into. I suspect that the Ovo 15p for heat pump consum...
Im going through a similar process, working out a sensible battery setup with ASHP, electric car and 4kWp of PV. I still cant get the finances to sta...
