This proves that with the "counter running backwards", the system as it exists in Belgium only hides the dust under the carpet, because it is unlikely that PV in Belgium is intrinsically more "profitable" (in the sense of the community) than in France or Germany. In Germany, the EEG surcharge (support for renewables) is around 65 € / MWh consumed.
In short, there is someone who pays for your virtual storage amounting to 400kWh today according to what you told us.
And there is especially someone who pays for the existence and the use of the network, which you hope to have reduced your personal cost to zero when you use it 24h / 24, that you inject or that you withdraw.
Well, it's like that in Belgium, you'd be wrong not to enjoy it, is it a sustainable model, it seems less safe.
