Hi,
I am attempting to build a RPI based system that runs a sensor and connects to the net via Cellular. The hardware is all built, runs great so now i want to look at deployment which needs to be solar due to no power availability.
When running and connected to the net i know the system pulls 3.8 amps and around 360 mAh per hour.
To manage the solar and add batteries i was looking at something like the Waveshare Solar Power Manager C which will take 3X 18650 Lithium Ion batteries and output 5V via USB C
With this info how would i work out what size solar panel i need. It will be installed in the UK and needs to operate in the winter so sunlight will be minimal during winter months.
