Is that payback time with a battery?

It’s about 7 years without and 10-12 with here in New Zealand.

I get some installed next month.




I'm in Northern Europe (54N) and when I had solar installed 3 years ago I calculated it would be around 7 years, without incentives and without a battery. The price has dropped a lot since then, so it would be under 5 years now.


With a battery. Costs have halved per kWh over the last year or so here.
