In this video, I show my Automatic Solar Light with Solar Tracker project.
This project is a combination of two separate circuits working together.
First, I made an automatic solar light circuit using a 100 mA solar panel, an IRF540 MOSFET, 10k resistor, 1N47 diode, and a 3.7V lithium iron battery.
During daytime, the solar panel charges the battery, and at night the LED automatically turns ON without any switch.
Second, I made an automatic solar tracker using two BD139 transistors, 200-ohm resistors, and LDRs.
The solar tracker helps the panel follow the sun throughout the day to get maximum sunlight.
Since the 3.7V battery is not enough to rotate the DC motor, I used a voltage booster module to supply higher voltage to the solar tracker circuit.
After combining both projects:
The solar tracker tracks the sun all day ☀️
The battery charges efficiently 🔋
At night, the LED turns ON automatically 💡
This project is simple, low-cost, and very useful for automatic outdoor solar lighting.
