A few people have been asking how much I’m saving now that my photovoltaic solar system is on. Well, so far, no matter how you slice it, I’ve not saved anything. In fact, it is costing me money.
I will try to keep this Google spreadsheet showing Gordy’s Solar Savings up to date with the actual values. If you have a Google Docs account, you can also try to view it here: Gordy’s Solar Savings in Google Docs.
Gordy, correct me if I’m wrong, but as I type this on 10/19, it appears that you are “chewing through” your upfront cost of $2,000 at a rate of $55.93 per month ($671.19/yr). Meaning your system’s upfront cost will be paid for in 2.98 years.
Have you considered what your ROI would be if you purchased instead of leasing?
