People often ask how my solar panels affect my electric bills. My total cost of electricity for 2017 was $521.37. Here’s a chart from my utility that illustrates my monthly electric utility bills. Note that my average monthly bill is $45.
If one assumes that the average monthly bill for a south Florida home is around $200, then I have saved $18,600 in electricity bills over the ten years my solar panels have been in operation. If one assumes that the average home’s bill is $250 a month, then I have saved $23,600 in ten years. Projecting my system’s operational life out to 50 years shows a saving of nearly $100,000.
