How do solar-powered street lights work?

#Charging

First, the solar charge controller will turn off LED lights towards dawn once solar panel voltage rise to 5v, which is accounted for a little sunlight in the morning.


#Discharging

When there is not enough sunlight towards dusk and solar panel voltage drops to a value under 5v, the LEDs will be turned on accordingly.

“Time control mode” and “Motion sensor control mode” will be working during discharging at night.

As the primary function, Time control is used to customize different brightness in different time slots. For example:

Time slot 1: 6:00 pm – 7:00 pm, 50% brightness

Time slot 2: 7:00 pm – 8:00 pm, 70% brightness

Time slot 3: 8:00 pm – 10:00 pm, 100% brightness

Time slot 4: 11:00 pm – 2:00 am, 50% brightness

Time slot 5: 3:00 am – 5:00 am, 30% brightness

And so on.

A motion sensor is used as a minor function which can be recognized as an energy-saving mode

The LEDs’ brightness will rise to 100% when someone is approaching the lights and then revert to the previous level of brightness 20 seconds after the man leaves.
