Four years is accurate for Australia. Almost one fourth of all homes in Australia have solar on them. The super fast payback period is why.
The payback period is so fast because Australia has the most expensive electricity in the developed world. Because of this, Australia also has the most developed residential solar installation industry in the world. The blokes in Australia can do a residential install for around a third of the price of a residential install in the USA.
