Yup, that holds true. And we hear people say aids are the only factor solar makes sense. So just for enjoyable, let's attempt it one more time without the tax credit:$ 16,660/ $1296 = 12.
4 years to 12. 8 years by employing an installer and skipping the tax credit, and we're still settling the expense midway through the life of the system. Solar costs a reasonable little bit of money in advance, but no matter how you slice it, grid-tied solar can pay for itself long before the devices breaks.
