    • How do I know if my solar trickle charger is working?

    I suppose that you could put a potentiometer across the solar panel leads and increase the resistance till the voltage across the solar panel is 19V again then you could calculate the current by measuring the resistance in case the solar panel simply doesn’t have the wattage to do anything measurable. That should give you an idea as to whether the solar panel is giving you the rated power. There’s no doubt that a lead acid battery would overwhelm a small solar panel hence the “trickle charger” label. The only true test is if the voltage across the battery manages to increase over time.

    If you connect a diode between the panel and the battery, will the voltage across the panel leads read 0.6 volts higher then the voltage across the battery leads? That would mean some current is flowing for the diode to let it through. It would be a good idea to have such a diode to limit self discharge through the panel anyways.
