Hi, I am on the hunt for methods for as the title says, "Detect when solar panel has sufficient power available". The vision is to build an arena where two robots 'battle' only while in direct sunlight. Each robot will have a solar panel and a microcontroller along with the drivetrain with no energy storage element besides a large capacitor for minor changes in sunlight. Using a 1W panel as an example with 200mA maximum rated current, I would like to know how to detect when the panel is capable of outputting at least 50mA at 5V before the load is connected. The problem I am having is how to approach detection when the detector is powered from the panel and so prone to the sudden changes in sunlight. One approach is to use a Zener diode. Thoughts are appreciated.
