Do you have a car, lawnmower, 4-wheeler, dump trailer, or any other application where you have a battery that sits for long periods and always goes dead just when you need it? A Simple $20-$30 solar trickle charger might be a way to avoid these inevitable headaches. I will test out a 7-watt panel to see if this will actually work without the need for a charge controller between the panel and the battery.

If it is a small tractor or dump trailer out in the AZ desert for a long period of time (months) I would err on the side of safety and add a cheap PWM inline.
But if you are getting only 4-5 hours of direct sunlight a day, and there are clocks and ECUs, it will be a good ebb & flow.
Do note that car windows are treated to reduce energy entering, so there will be a significant drop in performance inside the car.
A charged battery is a happy battery!
just get a generic OBD plug to bare wire and wire up + to pin 16 and - to pin 4
they should be able to handle up to 50W on the wire
It's probably even a good idea for a daily commuter who parks the ride up at the train station or at work for most of the day (sorry night shift workers...this won't work for you!!!!)
