My solar lights charges the rechargeable batteries. But in the winter there is not enough sunlight to keep the lights on all night.
The solar cells and batteries are in parallel; can I add an AC 3 volt DC output power supply to augment the existing solar cells?
It's an address light with 5 LEDs. The batteries are two 2.1 rechargeable in parallel with unknown spec solar cells. My idea is to add a 3V solar panel with diode in a south direction connected by a long wire to the unit.
