    Saving

    How much have you saved since you converted to solar power?

      Maybe it is time to move that off grid system to the mountains of Arizona.

          As of November 30, 2015 my accounting to date is as follows:

          Total Net Investment less Federal tax credits....$17,199.00 (does not include my labor cost)
          Total Cash Flow Project to Date including SREC credits of $1,197.83....$7,496.40
          Net Profit Project to Date (defined as Total Value of Solar Produced less Production Cost)......$4,151.56
          Return on Investment Project to Date....9.26%
          Estimated Payback.....6.4 years

          If I include the value of my internal labor the estimated payback would be 25.5 years and a negative ROI. If I had to pay someone to build or install my system it would not be viable.

            A year and a half ago I installed a 4 KW system, I paid $8,000 for all costs and received $2,400 back at tax time, so I'm $5,600 out of pocket. My average yearly power bills totaled $1,200 before that, but in the first year I over-generated slightly and broke even. So in the first year I didn't spend $1,200 for power that I would have otherwise.

              I haven't "saved" anything yet but by the numbers I have under 7 years until I reach the break even point and then I'll be set through 2034 when I'll worry about my contract with the utility expiring. With just over a year elapsed since I purchased my system I've only sent my utility about $250 which is the minimum connection fee for my grid-tie system. I paying $200 more towards my mortgage each month with the "savings".
