I'm in Australia and we recently committed to putting solar panels on the roof of our small office building. Pay-off projection in the estimate/quote was all of 2 years!

Nice! I had my solar panel installed on the roof of my house in 2015, and they have a pay-off projection of just over seven years. At the beginning of the year, my neighbor had solar panels installed, and we calculated his pay-off projection of just over four years (both of us took advantage of available subsidies).
