Stuart I think you would be better off moving to Octopus. You could send all your solar back to the grid @15p per kWh. You would be able to fill your car and battery every night 365 days a year @7p per kWh. Changing to Octopus would cost the same for running your car, 7p per kWh, so no difference there. Your battery would be filled at night so you would be running your house all year day and night for 7p per kWh assuming your battery is big enough to run your house. If you know how much electricity you consume per year stick it on here along with your solar generation for the year and we can see what it would actually cost with each scenario 👍
There I was, bimbling along quite happily in my own little world and you’ve come along and thrown a spanner into the works! 😁 We’ll have had it for a year, this December, and I’ll have the total amount of usage then but…youve sown a seed!
Cheers
