Anyone got good recommendations for a solar panel to sit in the car? Don't worry about wiring I'll deal with that. My car uses about 25ma quiescent, and 600ma when the becm is awake. All I want is to trickle it when stood still, I have a smart charger as and when I want to charge it properly, and a volt meter on the cigarette socket. I suppose 15W will give good coverage,
and diode protection to stop overnight discharge. Not sure if I need to care about a charge regulator, but they're not so expensive. SunPower monocrystalline seems to come up as good tech....blah blah, but does anyone have any specific ones to recommend?
