Have you run the ROI on that? It's been a while since I did one of these analysis with a customer. But, if I remember correctly, I'm 0 - 5 trying to sell "green" energy sources for private commercial companies.
Why? Because the ROI (Return on Investment) is always longer than the expected manufacturer's stated useful life. In other words...the monthly savings that your realize will finally pay for the initial investment for the technology 5 to 15 years after the technology quits working. It will never pay for itself.
Money matters in the real world.
Yes. My array is fully paid off in terms of reduced energy bills. It is still functioning. Not much bang for the buck, and there would have been better investments, but it’s pure (minuscule) profit from here on.
