Good on you. I have something like that too. But I still need an electric element for cloudy days.

However it's not what's normally meant by "free energy". I don't know why you're trying to make an argument out of this.

I used to live in a house with money-free energy, we paid nothing for electricity because the landlord was stealing it from the power company. But that's not what "free energy" usually means. Please don't redefine the term or it'll just cause confusion.

The sun consumes fuel. That's why it doesn't count as free energy. It won't last forever because it's always pouring away energy from "burnt" fuel.
