Now I did take into account the interest on the loan over the 20 years, and I am not including inflation due to the complexity that it will cause over all my calculations that I had to do to get these numbers.

105,281.03 initial loan that will be paid off in 20 years

After the 20 years it will only cost 533.50 per year after the 20 years

The other side of the equation will have 1,347 each year ( this represents a non solar system electric bill)

When will I break even?
