A Full Solar Home  powers your home and vehicles  with solar energy. Compare the cost of living in a typical home with gas-powered vehicles to living in the same home with Full Solar power and electric vehicles. Generations of Americans have worked 10 to 15 years of their lives just to pay  for energy and interest. They had no choice. Now, you do have a choice.  Now, free solar energy can power your home and vehicles, and the savings could pay for your home. This changes everything. This is a path to generational wealth for working class American families. This calculator shows how much you can save on energy, and how part of those savings can eliminate a decade of house payments and a fortune in interest.  It’s not magic. It’s math.  See for yourself.

How many years would you need to work to pay the difference?
What if you might move in a few years? You’ll be far better off with a Full Solar Home. Many people move several times over the years. They don’t accumulate much home equity because all of their mortgage payments are mostly interest. By following the Full Solar Home financial plan described above, you accumulate equity much faster, and pay less interest from the very first month. Your extra equity far exceeds the amount of your extra mortgage payments. When you’re ready to move, your Full Solar Home will sell faster, and for more, than a conventional home. Transfer your equity into a new Full Solar Home and continue your savings. Based on the mortgage and payment figures above, see how much more equity you have even in the early years of your mortgage.
