We had our solar system installed 1,5 years ago. No battery though as I decided to try the option they give you to pay for whatever you throw to the grid.
The market went very high last year and now prices are moderate. I plan to set up a complete off-grid system in our property in Portugal and maybe end up adding batteries to what we already have at home.
I may also try a windmill to complement the solar panels in Portugal as we are rural and there are no regulations there.
Our final goal is to try off-grid also here at home. My recommendation to anyone is to start getting into renewables, even if it is a small system, once you try, all you want to do is to grow in that direction, plus new panels and tech keeps coming to the market.
