In the UK, I've had a battery plus solar for just over a year. its a 5kwp set of panels and a 13kwhr battery. From mid march to late November, we only drew from the grid once (that was because we had a portable hottub setup, which took ~28kwhr to heat up.) Its raining and january and december are shit months for solar, well mostly because of the short days. December we were 45% independent from the grid. Currently we do not have heating or cooling from electricity. If that were the case we'd need 10kwp plus more storage.
