Firstly, I just want to mention that I am well aware that 'Free Energy' is only a concept and that no actual device known to man is capable of producing or harnessing free energy. My critical thinking faculties are in fine order, and I am well aware of James Randi - so please, no "free energy doesn't exist retard" answers. I am only interested in the concept of free energy, not in debating whether or not it exists.
Now, to my question: Why isn't solar energy (when absorbed by solar panels) considered to be 'free energy'?
Every proposal for a free energy device I've seen seems to involve some kind of equipment (often equipment that is quite expensive and cumbersome for something that doesn't even work), so I just don't see much of a difference between these types of technology and solar panels - except that solar panels actually work. So what is it exactly that makes something Free Energy?

Perhaps you are thinking of the thermodynamics concept of free energy (see the reference). Otherwise, it depends on who's counting and what they are counting. For photovoltaic and hydroelectric energy, there's no direct operating or fuel cost, but there is a capital cost for the equipment and infrastructure. You could even say petroleum is free, since we don't need to pay God for the oil.
If this doesn't help, tell us who is setting this standard and what they consider free energy.

Oil is the closest thing to free energy we have.
There is something called 'vacuum energy' or zero-point energy that exists but will probably never be harnessed. It's everywhere, even space.
Solar isn't free because even if you have the solar panels, you need to have some real estate to put them on. The sun won't last forever, either.

Free energy is that which is available when no energy input is involved. Solar energy is the result of fusion in the sun. It is difficult to debate this if you are unwilling to accept that perpetual motion does not exist nor is it possible.

Once the solar installation is up and running, it's essentially free. Setup for solar for a typical home is around $50,000
