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 :
Using a Multimeter to Test Solar Panels You can measure Volts and Amps with a special tool called a multimeter. There are 2 styles of multimeters in the following. When you use the switched multimeter.Please select the appropriate function on your multimeter. Most multimeters have functions for measuring several different quantities.
To test a 18V solar panel voltage output directly, put your solar panel in direct sunlight, set your multi-meter to the DC "volts" setting.
Testing Solar Panels For Amps To test solar panel amperage output, put your solar panel in direct sunlight, set your multi-meter to the DC "amps" setting. To ensure that you don''t blow your device''s fuse, set the maximum amperage sensitivity to well above your expected reading.
