I am a big fan of solar, we have 420 watts (yes I'd like more) which is more than most.
However, using solar to help power a coach's drive train is a little unrealistic: 746 watts of solar panel is a pretty good solar installation for an RV;
746 watts is ONE horsepower. 300HP (my rig) would be 223,800 Watts. :E That's more than 500 times than what I have on my roof right now. I could just barely get 0.18 percent.
Since the total solar energy reaching the earth's surface is on average slightly under 1400 watts(less than two horsepower) per square meter, even with 100 % conversion you would need an awful lot of roof real estate to make a noticeable difference. (Just to be silly: Roughly 8' 6" wide and 211 feet long for the whole 300 HP) :B
Back to reality. To power other than the drive train, solar is very worthwhile IMHO, and I would like to see a useable solar prewire, with large enough wires for the maximum number of panels that would fit reasonably on the roof and room for a reasonable bank of batteries.
