That's sort of my point. You are essentially getting to parity to a grid operator, who does not pay VAT.

I see, but the grid operator has to collect the VAT for every kWh from the customer. I don’t pay VAT for my balcony PV and also not for the energy I get from it. That is not parity, I as a producer have an advantage here.

This is a good point.

Yes true, vat exception is an advantage.
