I note VAT £1.88 VAT on a -£24.76 bill. Because VAT is on import not the total import and export.
I like I am sure many others, look at the off-peak of 8.625p/kWh and export of 12p/kWh, and it is both easier and cheaper to fully charge my battery rather than work out how much I will need.
Where the tariffs are closer off-peak to export, it is not so cut and dried, and it helps the grid to have solar panel and battery customers to charge the battery high enough, so there is no draw from the grid at the critical time 4 pm to 7 pm.
If I look at solar yesterday.
The solar dropped at 4:30 pm, but the state of charge faint purple line above it, shows the battery lasted out, which asks of why is the government not encouraging the use of battery storage more?
It seems nearly all grants are for panels only, no battery. I would say the battery saves us more per cost to install to the solar, but they do work together, and VAT on import only has been resulting in paying the government to store power for them.
But what well the government tax instead? We have seen some daft taxes through history, the window tax, and as people bricked up the windows a brick tax, which is why bricks became larger. Which in turn is why It's so hard to match brick sizes even today.
I look at this thread and wonder how such small solar panels help, I hope he gives us some info on how they work out?
