Have you done the numbers on how long it will take to pay this system off?
Yes, I have it somewhere. I think it was in the order of 10 years but I'd have to find the details to confirm that.
I didn't do it with the thinking of return on investment however. To me, it is an increase in property value, and a reduction in day-to-day costs which were big factors, and of course reducing my environmental impact.
I actually installed my panels in two stages. The second stage added 60% production, but cost slightly less than the initial 40% did. The costs are even less now. Couple that with input from the government, and the pay-off time would be much less if I installed it today with this policy in effect. Much more appealing to people whose main concern is strictly reducing costs.
I'm also a big fan of residential solar for redundancy and disaster resilience.
