I have a feeling that the Angle the light hits the surface at has a far
greater effect than a few piddly little million kilometers.

The angle of planet tilt added to the angle of the surface where you
live can drastically lower the quantity of energy hitting the surface in
the winter.

cosine(23 degrees tilt plus 50 degrees(where I live)) X available energy
= about a third of what's available.

I'm not good with spherical math, but I'm guessing that distance would
vary the energy per square unit in some ratio to a cube power...that
percent reduction would be multiplied by whatever the angle cosine gives us.

I have to go get a sweater now...
