Good to know
- Monthly saving assumes the solar system replaces your current irrigation cost fully during sunshine hours; night irrigation may still need the grid or a battery.
- The payback period is the system cost divided by monthly saving, so cheaper diesel means a longer payback.
- These are estimates for planning only. Panel output falls a little each year, and real maintenance can vary. Get a proper quotation from a solar installer before buying.
