I've managed to gather some bit's n pieces to start a project that I've been wanting to do for a while.
The initial aim is to run a raspi using a small 12v battery that's charged via a 50 watt solar panel
1 x 50w 12v solar panel
1 x 12v 20AH battery
20 amp Charge controller
Cannibalised usb car phone charger to get from 12v - 5v
Now I'd also like the raspi to monitor output from the solar panel and output to a wep page, what would be the best way to get that data?
I'm new to electronics so I dont know if it's one of the many add on boards that have popped up or if it would be easy to make a home grown solution.
Once I get the basic setup working, I'll replace the battery with a couple of leisure batteries and most likely another panel or wind turbine as this will end up being the power source for my external garage.
Thanks in advance
