Inside all solar lights is a circuit board or charge controller that also acts as a sensor or switch. When the sun is shining on to the solar panel the circuit board sends the charge from the panel to the battery. As soon as it’s dark, the circuit board or sensor recognises there is no light shining on the panel and stops charging the batteryGet a Quote

These chips are very ingenious. They contain a diode for charging the single NiMh cell from the solar panel, but also use the voltage from the solar panel to detect when it's dark enough to turn the light on. The circuit pulses a small inductor at about 100kHz to step up the voltage to drive the LED in a similar style to a Joule Thief circuit.

Modification of a typical solar path light with a standard 1000ma-hour NiMH AAA cell. I then replaced the small 4 cell solar panel with a larger 4 cell unit, which produced 150ma in the sun. Next, I simply changed the 470uH coil on the circuit board to a 22uH coil. The lower inductance increased the battery current to 40ma when the LED light was on, which translated to about 13ma LED current.Get a Quote
