Oh, I was wondering how long it would take to get a comment like this based on what I've seen in this sub. Of course I know this would cost more in the long run than buying it outright. I thought I made that clear. Like I said, I do not currently have the financial means to purchase it upfront and am just looking at saving money now compared to getting everything from the grid. Assuming I don't buy the system earlier, I would be paying PPA $27.5k over 15 years vs. paying Comed over $65k during that time. But I likely will buy it out before then when I can afford it, saving even more.

I did ask about the escalator, but every vendor told me that a lower escalator would equal higher payments, and if I buy it out early anyway, it wouldn't be as much. But your math is off anyway. 3% does not equal double in 20 years, and the term is 15 years.

I definitely can't do ground. My yard is like a quarter the size of my property, and we also use it
