I'm working on a project in wich I need to have a system running 24hrs
a day , power supply will be solar panels feeding a battery. Can any
one share with me formulas on how to calculate de Amp/hr for the
battery and the power of the solar panel?
Systems will consume average 80watts and need to keep running on a few
clowdy days as well.
Thanks for the assistance!



Watts = Amps * Voltage

The Amp/hr rating of the battery (I think) says that if the device draws
x amount of amps, the charge will last this many hours.

This should get you started.
