We did choose to put solar on our roof with heat pump when we built our home only four years ago and at the time, there was no certainty if this investment will be any good. This year we also bought a battery and can run the house with this setup from spring to autumn with small input from the grid.

Only winter sucks because the heat pump is less efficient when it's cold. Would be great to have better storage for the grid to get cheaper energy during that time.
