Solar Panels and ASHP worth it?

[MumofCandR]

Are solar panels with batteries and ASHP worth it? I'm looking at the solar panels with batteries and ASHP but from what I can tell the payback is very long. Even with a £20k Nationwide green 0% mortgage over 5 years it seems tricky to achieve payback. What's your experience, what did these systems cost and do you feel it's been beneficial to your lives in practice?

I have them with 6 batteries. Hugely beneficial to us. In the summer we generate and export so much that we have no bills including the standard charge as it’s covered. It’s only really December and January where we don’t get much. Best purchase we’ve made. Had them around 6 years now
