Most well-sized NZ home solar systems pay back in roughly 6–10 years, then generate effectively free power for the rest of their 25-year-plus life. This estimate assumes power prices rise about 4% a year — so the longer you wait, the more a system would have saved you. Adjust the system size and region below.
