Numbers still don't seem great as you aren't factoring in any interest. If you factored in even 5% you'd be more like 25 years return which is likely the life of a lot of stuff, or less. Adding in the rebates, etc I doubt they'd ever truly pay for themselves.
I paid cash for the system so not paying interest. Show me a bank that pays 5% interest and I'll jump right on that, stocks sure but that's never guaranteed.
Panels and inverters both have 25 year warranties on them. Everything else is standard electrical components that should easily last 25 years.
