If you've never noticed the FE effect of headlights, the effect of fitting a solar panel will only be 1/3 of that (ie you won't notice it). An SG2 will save you much more than a solar panel.

Realisitcally, if you're concerned about alt. load, reducing it is the first place to start. LED's throughout if done carefully, will improve safety, last forever and save fuel.
