    In standby mode the IO Expander only uses 37.6mA with 12V, but if you have 5V only 11mA. The IO Expander was designed to run in Hydroponics/Aquaponics systems that need to run off the grid, so yes it should work on a 12V panel with a battery.

    It makes it a whole lot easier using the IO Expander and takes a lot less code space on the Arduino since all the sensor drivers are written in the IO Expander.
