We got a 3KW system with a 10.5KW battery enough to power our (still) tiny household. Even in a few cloudy days. So now we are living off-grid in Central Portugal. Sounds cool, we are part of the trend. But to be honest it doesn't really feel like off-grid. We still rely on water/gas from the grid and a generator for our heavy machines. but yeh. Technically #offgrid
