That is pretty optimistic. The calculators I've used online estimate my payback at 18 years and my lifetime savings at about $18K, with $32K out of pocket up front for the install. But my roof is 50% through the lifespan and I was told they would not warranty it against leaks due to panel mounts unless I first replaced the roof. That's $25K.
My next house will be my forever home, a little farther south than where I am now in the PNW, and on a big enough piece of land to use ground mount instead of roof mount. But right now, I cannot make the numbers work. I'd love having solar but I am not spending five digits of extra money just for the fun of it.
