Hi, I have similar calculations, but Germany has a simpler model installing 800 W solar system without any paperwork for one electricity meter. Produced but not consumed electricity is not paid for. However it covers most use cases. It worked sooo well for my colleague, that he illegally installed second 800 W system on second phase (we have here mostly 3 phase systems in Germany). I am waiting for autumn/winter to get my system cheaper off season. The savings come in second year with regular prices and in third year with current insane prices.
