solar panel dusk to dawn circuit

Best answer


During the dawn time the load is disconnected from the battery and battery is recharged with the help of current from the solar panel. A simple dusk to dawn sensor is built using apotential divider formed around Zener diode Z1,resistor R8 and R9 and transistor T1to know the solar panel voltage by microcontroller.
