You know quite a bit.
DC can create a sustainable arc above 15 Volts. It does not require a motor or induction coil to do so. Multiple series interrupts are a way of handling the problem, but they do not eliminate the arc or the possibility it may start a fire.
One thing is for sure: if the people trying this have any degree of success they will crow about how they know so much more than engineers despite their success being 100% dependent on pure luck. But when they burn the place down they'll never post pictures of the disaster.
Now if you'll excuse me I'm going to feed my diplomas through the paper shredder and become an Internet Expert.

No doubt it will work. It won't be very maximized in power recovery though, without something back-regulating panel voltage. That's the purpose of the MPPT circuitry. With that fixed resistance load, at lower sun levels, production will be VERY small. By actually increasing the resistance (that's what the MPPT controller would do in this instance), panel voltage would be allowed to increase, to a point where the actual power produced would be higher. Solar panels are not like other voltage and/or current sources, in regards to I/E curves. Allowing as much current as possible to flow out of them does not necessarily make the most power.

Scary some of the things one reads on the internet. Could very easily lead to disaster. Hopefully (for the victim) the insurance company can be convinced the fire started elsewhere.
Soooooo, it works, then?
