The solar panel conversion of sunlight to usable energy to around 20%, with a theoretical max of 30%. So it's better than that.

That's not really relevant. They have a light source that runs on a fuel and are putting multiple PV cells around it. The efficiency they care about is the fuel in to electricity out. If you can put more cells around the light, the system efficiency goes up.
