Payback time varies on many things: your household energy use, how many panels you have, do you have a battery, how big is it, your energy tariff. etc.
My panels will have paid for themselves in 6-7 years from install.
Having a battery you can charge up on cheap overnight rates is also v helpful.
The old economy seven type tariff.
Or years ago we had a grass drying tariff on the farm that was virtually free if you used it during the correct hours.
