Today let's see how I built this mini solar power system with a battery to store energy. Do you need to power an electronics project with a solar panel because the place where it is mounted is not reached by electrical wires? That's just what I needed to do, to automate my balcony vegetable garden but without having wires everywhere. This solar system is perfect for powering an ESP32, an Arduino, an ESP8266, or other electronic boards with low power consumption 24-hour, thanks to the lithium battery.
