Re: Solar + alternator = faster charge?
If the sun is shining while you are driving down the road, they will both charge but the solar panel puts out a mouse-farts worth of power compared to the alternator........
As Brent mentioned above, when the alternator/voltage regulator is charging it's usually around 14V or so; when the solar controller sees the battery voltage that high it will go into float mode.
