I am building a system using an embedded board that appears to use about 1/4 to 1/3 AMP according to my bench power supply. Is this low enough power consumption for this system to be run off of some battery(s) charged by a solar panel no bigger than 3'x 3'?
EDIT: Why the down votes? Is it not a reasonable question? I'm not really an electrical engineer and I've never worked with solar panels before.
1- The board will be "active" for about 10 hours a day.
2- Board uses 5 volts.
3- I'm probably not understanding what my bench power supply is telling me about power usage. Each supply has an "AMP" reading in the form of X.XX and is currently reading about 0.22. I "assusmed" that meant the board is drawing nearly a 1/4 AMP. However the documentation for the board says typical power usage is about 250 mA.
4- The board is an Olimex SAM9-L9260 ( AT91SAM9260 ) that is sitting running Linux and sending output to a serial console as fast as possible ( counting ).
