There are different setups I have thought of and tbh mostly looked at battery only. So 4kWh = £1 normally or £0.20 off peak then you are saving £0.80/day.
But yeah, solar you can also use power while the sun is shining and the batteries are 100%. Mostly looked at stuff like jackery, anker solix, ecoflow. Can you have them plugged into the mains but they will only use the mains when the battery is empty rather than using the mains to charge the battery? Then the battery doesn’t have to be as large to still benefit from it and it can balance it out a bit through the day.
Downside is that the benefits of it might be harder to calculate.
