Soldato
I have Solar and an EV (Tesla). Currently considering battery. In the summer, the Solar pretty much covers my daytime use. Night time I try and move washing, dishwasher, etc to off peak where practical.That's a tricky call and for me would depend on which of these you have, solar/battery storage/ev and what your split is between on and off peak use.
I can't see the current go tariff being available by the end of Jan so if the bulk of your use is on the night rate I'd probably renew and guarantee a bulk of my use is at 7.5ppkWh for another 7 months after Jan.
I also WFH so there’s always usually someone home.
