The thing is, the solar panels were really buffed, they're now already 2/3 as space efficient as personal fusion (not taking into account that they don't work at night, 16 x 30 = 480 kW). In a way it makes this mod kinda deprecated, if the burner generator is only marginally more efficient, why even bother given the hassle involved. So I think it's reasonable for the burner generator to now be 1/3 more space efficient than personal fusion. The personal fusion reactor remains attractive as it's only slightly less space efficient, but completely hassle free.
