I am happy I got solar earlier this year. I thought it would be very expensive but we are very frugal with energy and it only was 7k euro to go off grid. During the day we can run anything (tons of sun so washing, dish washing, etc etc), during the night less so but we go to bed early (21:00) and get up at 5.
Next investment for you then would be chemical batteries to store power. Given that you are paying in Euros, how do you expect to get enough solar energy over winter?
Same in Spain when I lived there.
