You can check if your solar panel is charging a battery by using a multimeter. Connect the probes to the positive and negative wires from the solar panel and set the multimeter to the direct current voltage setting. If the multimeter shows a reading around 12-20v during peak sunlight times, the solar panel is working and charging the battery.
To test your solar charger, simply stick it out in the sun for a few hours and let it do its thing. Whenever it comes time to check the charge, be careful when picking up your power bank as it may be very hot to the touch after hours in the sun. Once safe to use, simply plug in your electronics and begin to power your life with solar energy.
The solar panel voltage is sensed by a voltage divider network consists of two resistors R1=47k and R2=6.8k. The output from the R1and R2 is connected to ESP32 analog pin GPIO pin 34. The output from the voltage divider is smoothed out by using a ceramic capacitor C1. Voltage Measurement :
