I want to design an LED street light operating on solar power. The maximum voltage and current output from the panel are around 16.4 V and 2.4 A. The light should get switched on or off automatically as per the ambient light conditions.
For this purpose photo-sensors are available, but I want to use voltage sensors. When it gets dark , the output from solar panel becomes low. If I take 4 V as the threshold, the light should get ON when the panel output voltage drops below this, and vice versa.
Can I use microcontrollers for this? But wouldnt the current (2.4 A) be quite high for a microcontroller?
Thank you
