How many Ampere hour of battery needed to power raspberry pi 3 for 24/7 using solar panel?

We are currently using raspberry pi 3 with fan, 3 infrared sensors, 1 ultrasonic sensor and 1 rain sensor. Our solar panel is rated 50W and we would like to power our rpi 3 24/7, can you recommend us how many Ampere hour of lithium ion battery needed to operate it 24 hours? thank you.

How can I make one delay for all sensor?

This code data logs IR, Ultrasonic and a raindrop sensor but the code prints for about 2 milliseconds each time and it overwhelms our sd card, we would like to make the delay for about 30 second each time to print but right now we don't know how to do that. Thank You import RPi.GPIO as GPIO from tim...

How to combine two infrared sensor codes for one program?

Hello, I am new to python and i would like to run my program based on the two infrared sensor to read two different readings of rpm of the two motor at the same time. Here is the code that we tried to make. #!/usr/bin/python3 import RPi.GPIO as GPIO from time import sleep import time, math dist_meas...
