ALTERNATIVE charging sources are much more expensive as voltage increases from 12 volts. With a generator and charger or solar panels this is not a challenge. But running down a highway with an alternator sitting on it's butt is perhaps the main drawback to higher voltage. I had two alternators on my Crown conversion. When both were engaged fully, you could see the fuel pump link arm move a quarter inch! This is back when a "real-deal" on Kyocera panels meant 290 dollars for 51 watts. Times sure have changed.
Try to PROTECT those L16's as much as possible from road shock.
