The list is to share
In your case , what I will do in your case is look to
reduce the lost of power in heat , try to use only
12vdc equipment, trasnformers and power inverters are
not good in the solar powered equipment
I will start with one battery size 27 or 29 deep cycle
full charge and the 45 w panel for a start, if your
solar controler have a low voltage control can save
your bateries and save the day, but most of the
Linksys run in low voltage with out problem (i use
those in 5v some times)
I get the idea for the solar sistem , but running
equipment at 24vdc equipment as repeater in a hill
top
good luck in your project
