Yes, except panels with regulated 5V out only exist retail with batteries. You'd want some small amount of electronics ideally connecting to the internal to ereader cell (3.7 V to 4.2V depending on charge).
But you don't even need built in panels and separate ones are easier to leave in the daylight on a windowsill.
