It looks like you didn't factor in the time value of the $11,000 initial cost. In 9 years, $11,000 invested at 5 percent per year, would yield an investment income of about $5,000. Also, have you factored in the cost to remove and re-install the panels when you replace the roof? This can cost about $3,000 to $5,000. And, during that 9 years, if you didn't have roof leak, you have been lucky. Try calling a roofer to repair even a small leak and tell them that the leak area is covered with solar panels. They will probably hang up on you.
