One way to look at solar power is as a “refinancing” of the expense of electricity over the years.
The basic idea is that power is a persistent and unending expense and the rate you are charged for it will continue to climb. Why not take that money and use it more wisely?
By taking all or a portion of your power bill and fixing its cost, you save during the payment period and then ultimately produce free power once it’s yours!
Think owning instead of renting a home. You clearly come out ahead buying a home in the long run.
Also, like mortgages, you can prepay the loan down without penalty and save a ton on interest.
