Hi, Greetings from Jaikumar. I am basically a farmer. Would like to know if someone could help me to design automatic solar powered light to trap insects in farm

The system should have 12v battery, 12v solar panel, 3 set of 8x1.5v(12v) ultraviolet LEDs in parallel.

During daytime, the battery need to charged from solar panel

At 6pm, the LEDs need to powered on and at 10pm, the LEDs need to powered off.


In case of any issues in powering the pic (which affects the timer), we need a press switch to be reset the timer. It could be done at particular time say 8am

I would suggest using a light sensitive diode instead of a timer and eliminate a microcontroller completely

Good point but the OP wants the unit to run at night only until 10pm.
Some timer mechanism would be required.

Starting point would be a link to the ultraviolet LEDs you want to use.
Need to work out how much drain on the battery during the night and allow for rainy/overcast and seasonal solar charge times on the battery.
Average hours of daylight at your location would also be a consideration.
